From the document EP 0916908 B1 discloses a device of the heat exchanger for the heating system of the vehicle, which has a heat exchanger housing, made mainly in the form of a bowl. The outer part of the casing of the heat exchanger is formed with an external surrounding wall and the outer wall of the bottom. The inner part of the Cup-shaped housing of the heat exchanger has an internal okra�surrounding wall and the inner wall of the bottom and is installed in the outside of the housing, so with her it limits the space for the flow of coolant. Located at a distance from the outer wall of the bottom or inner wall of the bottom end zone of the inner part of the housing it is formed with surrounding the inner surrounding wall made mainly in the form of a ring and is attached to the inner surrounding wall in its axial end area of the area of the outer surrounding wall to which is hermetically attached to the outer surrounding wall of the external body. This area of the outer limits of the surrounding wall along with lying in the same axial zone, which refers to the longitudinal axis of the Cup-shaped housing of the heat exchanger, a portion of the inner surrounding wall of the annular intermediate space which prepares the portion of the space for the flow of coolant and which is not closed radially outside the outer surrounding wall.

On the inside of the housing in the axial zone of the area of the outer surrounding wall, i.e. in the axial zone in which is formed an annular intermediate space forming a portion of the space for the flow of coolant fitting provided for the flow of exhaust gas. It passes through an annular intermediate space and is open by limiting radially �Nutra annular intermediate space of the inner surrounding wall surrounded by the inner wall of the internal space of the heat exchanger. When integrated in the heating system of the vehicle via it's internal space of the heat exchanger is leaking exhaust gaseous products of combustion so that the heat from the exhaust of gaseous products of combustion may be collected inside the housing of the heat exchanger and transferred to the environment of the coolant, i.e., for example, water flowing in the space for the flow of coolant. Exhaust gaseous products of combustion exit the interior space through the nozzle for the flow of exhaust gas passing through the annular intermediate space between the area of the outer surrounding wall and an inner surrounding wall.

On the outer surrounding wall of the outer housing, where it borders with the outer wall of the bottom, provided the fittings for the flow environment of the coolant, which are open from the space for the flow of coolant and thereby provide the supply or acquisition environment of the coolant in the space environment for a heat transfer or space for environment-coolant. Fittings for the flow environment of the coolant is, for instance, in the same surrounding area, and provided on the inside of the hull fitting for the flow of exhaust gas.

The object of the present invention is to net�live heat exchanger device, in particular, for the heating system of the vehicle, which would have a simple design that can be easily manufactured.

According to the invention the problem is solved by the device of the heat exchanger, in particular for the heating system of the vehicle containing located along the longitudinal axis of the Cup-shaped heat exchanger housing with the outer wall and the inner wall, and between the outer and inner walls formed a space for the flow of coolant, and on the outer wall is provided, at least one fitting, outdoor side space for the flow of coolant, and wherein on the housing of the heat exchanger has one fitting for the flow of exhaust gas, an open side surrounded by the inner wall of the internal space of the heat exchanger, the housing of the heat exchanger contains the outside of the housing with the outer surrounding wall and outer wall of the bottom and the inside of the shell with the inner surrounding wall and the inner wall of the bottom.

In this case, furthermore, provided that, in located at a distance from the outer wall of the bottom axial end, the outer surrounding wall of the outer housing is provided, at least one fitting for the flow environment of the coolant.

In the proposed and in�finding device design of the heat exchanger in the axial zone of the outer surrounding wall is provided, at least one fitting for the flow environment of the coolant, which is installed close to the open end prepared by an external body portion, prepared, in General, also in the form of a Cup-shaped structure, and thus becomes easily accessible during the manufacturing process. As this kind of part of the body, in General, are made in one casting, and because the molds must be inserted into each other by setting, at measures, one fitting for the flow of the medium is the coolant located at a distance from the outer wall of the bottom axial end, the outer surrounding wall as an integral element of the external body, you can easily install a choke for the flow of coolant, and after the casting process the necessary fittings just separate from each other.

To ensure a reliable flow of the medium in space for environment-coolant, it is proposed to provide on the outer surrounding wall two fitting for the flow environment of the coolant, mainly in the same axial area of the outer surrounding wall at a distance from each other. When you do this, then one of the fittings may be used for the supply of environment-the coolant and the other for discharging the environment of the coolant.

On�the audience when preparing a Cup-shaped housing of the heat exchanger outside of the housing and the inner part of the housing are inserted into each other, especially preferably, at a distance from each other were provided, at least one fitting for the flow of the medium and coolant fitting for the flow of exhaust gas in the same axial area of the heat exchanger. This prevents interference from the opposite side of the two housing parts when they are fitted into each other. At the same time on the device of the heat exchanger in the axial zone of a prepared area of accession, allowing compactly, for example, in the vehicle, connect the pipes and to provide easy access to them.

So, given the fact that the fitting for the flow of exhaust gas is provided in the interior of the casing to provide a relatively large amount of space for the flow of fluid, surrounded by an outer surrounding wall of the external body, in the surrounding zone of the outer surrounding wall to install an external surrounding wall at a greater distance from the outer wall of the bottom, and the second environmental zone of the outer surrounding wall to install an external surrounding wall at a smaller distance from the outer wall of the bottom, and in the area of the first environmental zone is provided at least one fitting for the flow environment of the coolant. For example, will provide the�, so the external surrounding wall in which is located at a distance from the outer wall of the bottom end zone relative to the longitudinal axis of the housing was mounted at an angle. Note that alternative possible a stepped transition between the surrounding zones with different distance from the outer wall-bottom.

The holding of a casting process with the use of appropriate molds for the installation of the integrally formed on the outer surrounding wall of the nozzle for the flow of the medium can be then particularly simple manner, if provided, at least one fitting for the flow of the medium in fully serving on the axis on a second surrounding outer surrounding wall surrounding the outer surrounding wall in the first surrounding area.

To through the inside of the housing, or the inner surrounding wall to limit the space for the flow of coolant in the axial direction so that on the inside of the housing to provide a constructive space to install the fitting for the flow of exhaust gas, it is proposed to provide on the inner surrounding wall of the inside of the housing end surface limiting axial space for the flow of the medium-heat�of osicala, and the first environmental zone of the inner end of the surrounding wall surface is located at a greater axial distance to the inner wall of the bottom, and the second surrounding area, the inner end of the surrounding wall surface is at a smaller axial distance from the inner wall of the bottom. Wherein the end surface may be located, for example, at an angle relative to the longitudinal axis of the housing. Alternative it also may provide a stepped transition between areas with different axial distance to the inner wall of the bottom. In the area of the end surface of the outside of the housing can be connected to an internal body portion, and fitting for the flow of exhaust gas is provided preferably on the inner surrounding wall, that is where by a corresponding constraint space for environment-coolant-axis provides sufficient structural space along the axis on the inside of the housing to prepare the opening extending into the inner space of the heat exchanger.

The end surface can be prepared on the inner surrounding wall preferably by stepwise increasing the thickness, and here, mainly, but not necessarily, may be formed from one vertical level. Also �may be provided with a curved transition into a face surface, or in a zone with a greater thickness of the surrounding wall to provide an increase in the thickness and thereby to prepare the end surface.

Proposed in the invention, the heat exchanger device is connected, in the General case, located at a distance along the axis from the walls-the bottom of both parts of the body the end zone Cup-shaped housing of the heat exchanger with other units, in particular the area of the burner. So is there a simple way to prepare a tight connection that prevents the exit of exhaust gases, it is proposed to install an internal surrounding wall, mainly orthogonal relative to the longitudinal axis of the housing, in its end area located at a distance from the inner wall of the bottom.

In an embodiment which is particularly preferred, from the point of view of technical performance, it is proposed to limit the space for the flow of coolant radially on the outside, only through the outer surrounding wall of the external body. There is no need to prepare the area of the undercuts on the inside of the housing, in order, the same way as it was done in the quoted first level of techniques, by preparing a section of the outer surrounding wall on the inside of the housing, to limit the portion of the space for ol�of takane environment-coolant only through the inside of the housing. Thus fitting for the flow of exhaust gas does not pass, as it is made in the prior art, via formed in the inner housing of the heat exchanger annular space, and it is located outside the space for the flow of coolant. This can lead to deterioration of heat transfer efficiency, but allows to simplify the manufacture of the inside of the housing with integrally provided on the nozzle for the flow of exhaust gas in one casting operation.

As mentioned above, through the proposed in the invention embodiment of a housing of the heat exchanger can be particularly simple to perform integrally the outside of the housing, at least one nozzle for the flow environment of the coolant and/or perform integral internal part of the body with one fitting for the flow of exhaust gas.

In the proposed in the invention structure in contact with the relatively hot exhaust gaseous combustion products comes mainly only the inside of the shell. For this reason, mainly to produce it in the form of metallic parts obtained by injection molding, for example, from aluminum. The outside of the housing, in General, are not exposed to such high temperatures, therefore, with a�Yu save costs and reduce weight, mainly it is possible to prepare plastic molding under pressure.

In addition, the invention relates to the heating system of the vehicle containing the area of the burner is fed with fuel and air required for combustion, and heat exchanger device according to the foregoing.

The invention is further described in detail with reference to the accompanying drawings, in which:

Fig.1 - Cup-shaped heat exchanger housing with the outer body portion and the inner part of the body in detailed view and a side view;

Fig.2 - view of the outside of the housing in the direction II, indicated in Fig.1;

Fig.3 - view of the outside of the housing in the direction III indicated in Fig.2;

Fig.4 - view of the outside of the housing in the direction IV indicated in Fig.2.

Fig.1 shown in the drawing on the image in the disassembled view of the housing of the heat exchanger heat exchanger device 10 is indicated in General position 12. Made along the longitudinal axis of the casing L and having a Cup-shaped structure of the housing 12 of the heat exchanger contains the outer part 14 of the housing and the inner part 16 of the housing. The outer part 14 of the housing and the inner part 16 of the housing, respectively, have also been prepared, mainly by using a bowl-shaped structure.

The outer part 14 of the housing contains the waggons�Uchenye in Fig.1 by the dotted line outer surrounding wall 18 and the outer wall of the bottom 20. The inner part 16 of the housing contains, also marked with a dotted line, the inner surrounding wall 22 and the inner wall of the bottom 24. In the assembled state of the casing of the heat exchanger 12 of the inner part 16 of the casing installed in the outer portion 14 of the housing, and together they limit the space for the flow of coolant. The inner part 16 of the housing limits the internal space 26 of the housing 12 of the heat exchanger, wherein the integration of such devices of the heat exchanger 10, for example, in the heating system of the vehicle, you'll be the flame tube coming out of the burner zone. Produced during combustion exhaust combustion gases pass through the flame tube at the inner floor wall 24 and there are rotated radially outward relative to the longitudinal body axis L. Then they occur between not shown in Fig.1 AME tube and the inner surrounding wall 22 back to located at a distance from the inner wall of the bottom end 24 of the 28 internal area of the surrounding wall 22. In this end area 28 of the inner part 16 of the housing, or the inner surrounding wall 22, ends mainly orthogonal relative to the longitudinal axis of the casing L, so you can simply connect the inner part 16 of the housing, or heat exchanger device 10 to perform de�Lichnoe connection space for the flow of exhaust gas, for example, in the area of the burner of the heating system of the vehicle. Exhaust gaseous combustion products out from this internal space 26 through the opening 32 to discharge gas existing in the inner surrounding wall 22, as well as the fitting 30 to the exhaust gas outlet.

On the inner part 16 of the housing, or on its inner surrounding wall 22, near the axial end areas 28 are provided with end surface 34, limiting space for environment-of the coolant in the axial zone, located at a distance from both outdoor walls 20, 24. This end surface 34 can be prepared, for example, by stepwise increasing the thickness of the inner surrounding wall 22. Fig.1 one can see that the end surface 34 which surrounds the longitudinal axis of the casing L, mainly in the form of a ring, is held at an angle relative to the longitudinal axis of the casing L, so that when finished, in the General case, in the form of a ring inner surrounding wall 22 in the region of its outer surrounding wall end surface 34 has the shape of an ellipse. Thus, as shown in Fig.1, the end surface 34 is mainly flat, i.e. in a plane set at an angle relative to the longitudinal body axis L. it is Also possible to modify or partially change the shape of the end surface�ti 34 relative to such plane; for example, the end surface 34 may be in the form of a cone. Regardless of whether the end surface of the flat or, for example, conical, or, if necessary, also curved, it is located so that it together with its structure, passing, in the General case, in the form of a ring around the longitudinal axis of the casing L, is set at an angle relative to the longitudinal axis of the housing L.

By the inclined installation of the end surface 34 relative to the longitudinal axis of the housing L is obtained, the configuration such that the first surrounding area 36 of the inner surrounding wall 16 of the end surface 34 is located at a greater distance from the axis relative to the inner wall of the bottom 24 than the second environmental zone 38 located mainly diametrically opposite relative to the first environmental zone 36 of the inner surrounding wall 22 relative to the longitudinal body axis L. In this case formed by increasing the thickness of the inner surrounding wall area 22 of the inner part 16 of the housing receives, in the General case, a wedge-shaped configuration, as seen in the side view in Fig.1.

In accordance with such an inclined installation of the bounding axis space for the flow of coolant end surface 34 of the inner section 16 of the housing outer surrounding wall 18 external�the second part 14 of the housing is formed so the first environmental zone 40 external surrounding wall 18 is located at a greater distance along the axis relative to the outer wall of the bottom 22 than the second environmental zone 42 of the outer surrounding wall 18, located mainly diametrically opposite relative to the first environmental zone 40 external surrounding wall 18 relative to the longitudinal body axis L. This means that the outer surrounding wall 18 in its end area 44 located at a distance from the outer wall of the bottom 20, is installed at an angle, and it provides mainly the same angle of inclination relative to the longitudinal axis of the housing L, as and for the end surface 34. In the assembled state of the external surrounding wall 18 adjacent its axial end area 44 to the inner surrounding wall 22 in the area formed by increasing the thickness or increasing the external ambient size to prepare the end surface 34. This axis may be formed adjacent to the end surface of the connecting stage 46, which can slide the outer surrounding wall 18 of the outer part 14 of the housing so that the two parts 14, 16 of the housing has occupied a certain position relative to each other, or were centered relative to each other. The connection of the two parts 14, 16 of the housing can be formed mainly by connecting m�materials, for example, with adhesive, whereby at the same time can also be formed hermetic isolation limited the two parts 14 and 16 of the housing space for the flow of coolant. In accordance with the connection level 46 on the inner surrounding wall 22 may be formed by additional connecting stage 48 on the outer part 18 of the housing, which can lead to an increase in the surface compound and the formation of additional labyrinth seal.

With the above construction is achieved that formed between the two parts 14, 16 of the housing space for the flow of coolant is limited radially on the inside exclusively through the inner surrounding wall 22, namely with its adjacent to the end surface 34 of the section to the inner wall of the bottom 24, the space for the flow of coolant is restricted in the axial direction is located at a distance along the axis from both walls of the bottom 20, 24 of the end zone only through the inner part 16 of the housing, namely by the end surface 34, prepared by radial expansion of the inner surrounding wall 22, and that the space for the flow of coolant is limited radially on the outside, mainly, exclusively through� outer surrounding wall 18 of the outer part 14 of the housing. However, the inner part 16 of the housing are formed of a compulsory area of undercut, which in the zone of the inner part 16 of the housing limit the space of the heat exchanger radially outside relative to the longitudinal axis of the housing L, which allows to make a product for one casting operation and to simplify the production process. However, one should note that one should not exclude the preparation of such zones undercuts, for example, within the first environmental zone 36 of the inner surrounding wall 22, for example, if it is necessary to control the flow. However, in the future adjacent to the end face 34 of the radially extending area of the inner surrounding wall 22 is free from such kind of undercuts, so that, as will be stated hereinafter, the fitting 30 to the flow of the exhaust gas in fact is also outside space for the flow of coolant, so don't miss it.

This positioning of the fitting 30 to the flow of the exhaust gas can be achieved due to the fact that, as shown in Fig.1, the fitting 30 to the flow of the exhaust gas is installed in the second environment area 38 of the inner surrounding wall 22, i.e. in the zone, which at least is in this surrounding area of the entire device of the heat exchanger 10, the outside space of lapotka environment of the coolant.

On the outer part 14 of the housing for supplying environment-of the coolant in the space for the flow of coolant is provided by two connecting pipes 50, 52, for the flow environment of the coolant, which is also shown in Fig.2 and 3. They form respectively leading to the space for the flow of coolant apertures 54, 56 and are connected with the respective conduits for supplying, for example, the fluid coolant to the space for the flow of fluid and for discharging medium-temperature space for the flow of coolant. Both fitting for the flow environment of the coolant can be installed mainly mainly parallel to each other and at a certain distance from each other, when viewed from the external side of the surrounding wall 18.

Both fitting 50, 52 for the flow of coolant is provided on the outer surrounding wall 18 in the area of their first environmental zone 40, i.e. the region in which the outer surrounding wall 18 is located relatively farther from the outer wall of the bottom 20. In this case mainly the two nozzles 50, 52 for the flow of the medium is the coolant located in the axial zone of the outer surrounding wall 18 in the same first environmental zone 40, which is located on the axis, mostly, completely, located on diametrically proti�Pologne relative to the longitudinal axis of the housing L of the second surrounding area 42 of the outer surrounding wall 18. This leads to the fact that, as shown in Fig.4 is a side view of the outer part 14 of the housing, both holes 54, 56 do not overlap along the axis opposite relative to the longitudinal axis of the housing L of the outer surrounding wall 18. Thus, in the manufacture of the outer part 14 of the housing during the casting can be very easy to install, and after the casting process to remove the fittings for casting, which is necessary for preparation of the holes 54, 56 and surrounding the openings of the fittings 50, 52 for the flow environment of the coolant.

In the assembled state of the two parts 14, 16 of the housing both fitting 50, 52 for the flow environment of the coolant are arranged with their openings 54, 56 in the surrounding area of the housing 12 of the heat exchanger, which is located opposite, i.e., diametrically opposite the same environmental area, relative to the longitudinal axis of the casing L in which is located the nozzle 30 for the flow of exhaust gas. Given the fact that the outer part 14 of the housing, in its end area 44 ends at an angle, both fitting 50, 52 for the flow environment of the coolant in the assembled state is located mainly in the same axial zone, and educated in the inner part 16 of the housing fitting 30 for the flow of exhaust gas. The term "in the same axial zone" mainly means that the fittings 0, 52 for the flow of the medium and coolant fitting 30 for the flow of exhaust gas overlap in the axial direction, at least in the zone, preferably a greater part of its distribution along the axis. Given the fact that these two types of fittings are provided at different positions of the housing 12 of the heat exchanger, it is possible without problems. The casing 12 of the coil axis at a distance both outdoor walls 20, 24 is formed, the area of adhesion, which, on the one hand, can be connected to the piping for supplying or discharging the environment of the coolant, on the other hand, can be connected in a pipeline control system for exhaust gases.

Using the proposed in the invention structure can easily be fabricated in a single operation of molding the two parts 14, 16 of the housing, respectively, together with provided for therein integrally fittings 30 or 50, 52. The interior 16 of the housing can be made of metal in a single operation by molding under pressure, for example, made of aluminum, so that a relatively high temperature can damage this inner part 16 of the housing. The outer portion 14 of the shell which has a lower thermal load, can be made of plastic in a single operation of injection molding.
