The present invention is intended for use in devices for lining plate heat exchanger and methods of manufacture plate heat exchanger, containing a package of heat exchanger plates and the end plate, which has an external side and an internal side facing the plate pack, and at least one hole.

Know the use of lining in the holes of the end plates of the plate heat exchanger. In accordance with the usual method is original material which is omitted from the deep part of the tube and the flange portion encircling the pipe section and being radially outside part of the tube at one of its ends. The other end of the pipe is inserted into the hole of the end plates and through it so that the flange portion to attach end-to-end to one side of the end plates. Then the other end of the pipe bend outward to form a flange, attached end-to-end to another side of the end plates. This lining has a few drawbacks. The manufacturer of the source material is performed in several stages with intermediate heat treatment. Under some conditions you may experience problems associated with the quality of the bend of the flange due to the formation of cracks. The installation of the lining is performed in several stages. In p the tent SE 456856, 07.11.1988 disclosed lining for the hole plate heat exchanger. The document revealed two variants of implementation. The first version of the implementation, which is described in more detail, corresponds to the usual technical technique described above. The second variant of implementation concerns the lining is divided into two sections, with the first section and the second section. The first section made of sheet metal and has an essentially cylindrical part of the pipe and the flange portion, passing out from the side of the pipe. The second section is also made of sheet metal and has an essentially cylindrical part of the pipe and the flange portion, passing out from the side of the pipe. Part of the pipe is introduced into the hole so as to form a region where the above-mentioned part of the tubes overlap. Part of the pipes are connected to each other by welding, but not shown, how is welded connection.

Patent US 4482089 And 18.07.1989 also discloses different embodiments of the lining for the hole plate heat exchanger. In this case, one version of the implementation corresponds to the usual technical technique described above. Another variant of implementation relates to a lining made from a portion of the pipe, which is inserted into the hole. Flange weld at each end of this pipe section.

The objective of this from the retene is to overcome the above problems and provide an improved device of the lining or other openings in end plates. In particular, it is aimed at a device of the lining, which can make easy manner and which has an improved quality.

This problem is solved by using a particular at the beginning of the lining device for a plate heat exchanger, which includes a set of plates (1) of the heat exchanger and the end plate (5, 6)having an external side and an internal side facing the plate pack, and at least one hole, the device of the lining (15) also contains the first section (16), which is made of sheet metal with thickness of material and has an essentially cylindrical part (16A) of the pipe and the joint portion (16b), and the second section (17), which is made of sheet metal with thickness of material and has an essentially cylindrical part (17A) of the pipe and the joint portion (17b), in which part (16A) of the first pipe section adapted for insertion in said hole, and a portion (17A) of the second pipe section adapted for insertion in said hole in part (16A) of the first pipe section so that the formed region (19), in which the said part of the tube overlap and in which the first section (16) is connected with a second section (17) by means of a welded joint (18), and according to the invention the thickness of the material of the first section is greater than the material thickness of the second party is a, at least in said region of overlap.

Because during the installation of such devices lining in these two areas of deformation of the material does not occur, the risk of formation of cracks in the inner joint part is significantly reduced.

As the thickness of the material of one section is greater than the material thickness of the other, at least in the above-mentioned overlap, i.e. the thickness of the material, at least one part of the pipe is more than the other part of the tube, eliminated the risk of contamination of the material near the weld and in the transition between the end plates, which are usually made of carbon steel, and the two sections.

In addition, the first section, which has a greater thickness of material than the second section, allow the second section during welding pressed on the first section so that the air is possible between the parts, and accordingly, gaseous oxygen is forcibly removed. Therefore, eliminated the need for so-called Gaza root of the weld, i.e. in the supply of inert gas, for example argon, to replace the gaseous oxygen in the welding field.

Each of these two plots can be made for single stage production without any intermediate heat treatment. The mounting device m is ovci in an end plate is very small, and weld beneficial you can perform an unattended way.

In accordance with the embodiment of the invention the sheet metal of the first section has a thickness greater than 1.5 mm, at least in these overlapping areas. This thickness is sufficient to prevent contamination of the material and reaction forces applied in connection with the above compression sections relative to each other.

According to an additional variant of the invention, the weld passes essentially around the entire portion of the tubes of the first section. In addition, a portion of the second pipe section may have a first end which is adapted for insertion into a portion of the first pipe section, where the welded joint is used at the said first end.

Then in esrea butt portion may have an outer side, looking from the package wafer and which includes at least one recess, such as one or more recesses to accommodate the sealing element between the said outer side and the pipe connection, where the sealing element can be pressed against the mentioned outer side of reliable and trouble-free way. Butt portion of the first section favorably formed in the shape of a flange part which passes around a portion of the pipe and substantially radially outward from the pipe section, and a butt portion of the second area is formed in the shape of a flange part which passes around a portion of the pipe and substantially radially outward from the pipe section.

In accordance with an additional embodiment of the invention the portion of the first pipe section adapted for insertion in said aperture with the outer side of the end plate, and part of the second pipe section adapted for insertion in said opening with the inner side of the end plates. This option is favorable and gives the opportunity to produce the first external portion of a single piece of material with a relatively large thickness of material, and the second inner land from one individual to another piece of material with the relatively small thickness of the material. The problem can be solved by using the define Lenogo first plate heat exchanger, contains a batch of wafers (1) of the heat exchanger and the end plate (5, 6), which has an external side and an internal side facing the plate pack, and at least one hole and lining device (15)which is mounted in said hole, in which the device of the lining includes a first section (16), made of sheet metal with thickness of material and having an essentially cylindrical part (16A) of the pipe and the joint portion (16b), and the second section (17)made of sheet metal with a thickness of material and having an essentially cylindrical part (17A) of the pipe and the joint portion (17b), in which part (16A) of the first pipe section adapted for insertion in said hole, and a portion (17A) of the second pipe section adapted for insertion in said hole in part (16A) of the first pipe section so as to form a region (19)where the above-mentioned part of the pipe overlap each other, and in which the second section (17) connected to the first section (16) by means of a welded joint (18), and according to the invention the thickness of the material of the first section is greater than the thickness of the material of the second segment, at least in said region of overlap.

In addition, the problem is solved using the method of manufacturing a plate heat exchanger containing the plate pack Teploobmennik end plate, which has an external side and an internal side facing the plate pack, and at least one hole. Moreover, the method includes the steps of providing the first section, which is made from sheet metal with thickness of material, and this site has essentially cylindrical part of the pipe and the joint portion; providing a second portion which is made from sheet metal with thickness of material, and this site has essentially cylindrical part of the pipe and the joint portion; introducing a portion of the tubes of the first section in the above-mentioned hole injection pipe section of the second segment in the above-mentioned hole in the portion of the first pipe section so as to form a region in which said portion of the pipe overlap each other, where the thickness of the material of the first area larger than the thickness of the material of the second segment, at least in said region of overlap, and joining the parts of the second pipe section to pipe section of the first section through the use of a welded connection.

The present invention is illustrated in more detail by describing the various embodiments disclosed by example and with reference to the accompanying drawings.

Fig. 1 schematically depicts a view in cross section of a plate heat exchanger.

Fig. 2 depicts in more detail a view in cross section of the hole with the device of the lining of the end plates of the plate heat exchanger of Fig. 1.

Fig. 3 schematically depicts how the device of the lining applied weld connection.

Fig. 1 discloses a plate heat exchanger according to the first variant embodiment of the invention. Plate heat exchanger includes many of the plates 1 of the heat exchanger, which form a plate pack. Plate 1 of the heat exchanger is compressed to such shape that when they are near each other in the above-mentioned plate pack, there is a gap IU the remote control each pair of plates 1. The gaps between the plates are intended for the formation of the first passages 3 for the first fluid and the second passages 4 for the second fluid. The first passages 3 is separated from the second passages 4. Plate heat exchanger also includes two end plates 5 and 6, between which is secured the plate pack.

In addition, the plate heat exchanger includes four through-channel 7, 8, two of which are shown in Fig. 1. Each lock channel 7, 8 passes through all of the plates 1 and at least one of the end plates 5, 6. Two of the shafts 7, 8 are connected with the first passages 3, and the other two flow channel connected with the second passages 4. It should be noted that the plate heat exchanger according to the invention can also be of a type containing a different number of flow channels 7, 8, for example 2 or 6 shafts and / or a different number of passes to 3, 4 to fluid heat exchanger. Each lock channel 7, 8 is formed from a cutout or hole in each plate 1 and one of the end plates 5. The holes are preferably, but not necessarily, represent the circumference in the direction of the shafts 7, 8. Each lock channel 7, 8 is connected with the pipe 9, which passes from the plate heat exchanger. More precisely, a passage 7 forms a first inlet channel which is designed the n to transfer the first fluid to the first passages 3, and a passage 8 forms a first outlet channel, which is intended to move the first fluid medium from the plate heat exchanger of the first passages 3. Two other flow channel formed in the same way, so the second inlet channel is intended to move the second fluid to the second passages 4 and the second outlet channel is intended to move the second fluid medium from the plate heat exchanger of the second passages 4.

Plate heat exchanger, expanded in Fig. 1, the plate 1 is compressed relative to each other between two end plates 5 and 6 by means of bolts 12 passing through the plate 1 and the end plates 5, 6. However, the plate heat exchanger at the same time may also be supported by other elements that differ from passing through bolts, for example, elongated elements, tight around the package of plates and end plates 5, 6. In this case, between the plates 1 may be provided with gaskets (not shown)to separate from each other, the above passages 3 and 4.

In the holes in the end plates 5 provided with the device of the lining 15. The device of the lining 15 has been further elaborated in Fig. 2 and 3. The lining device contains a first outer section 16 and the second inner section 17. Two sections 16, 17 are connected to each other through a welded joint is 18. Two sections 16, 17 contain corresponding essentially cylindrical part 16A, 17A of the pipe that goes into the hole. In addition, both plots 16, 17 include respective butt portion 16b, 17b, passing around the corresponding part 16A and 17A of the pipe and attached flush with the corresponding surface of the end plate 5. In the disclosed embodiment, the butt portion is formed in the shape of flange portions 16b, 17b, which are essentially radially outward from the corresponding parts 16A and 17A of the pipe. However, it should be noted that these joint parts can also be shaped differently. The outer joint part, for example, may have a certain shape for connection with a pipe or similar device and contain threaded, bayonet frame, etc. of the Flange portion 16b of the first section 16 is thus connected end-to-end to the outer side of the end plate 5 and the flange portion 17b of the second leg 17 is attached flush with the inner side of the end plates 5. In addition, the portion 16A of the first pipe section connected end-to-end environmental bounding surface 5' of the hole. Part 17A of the second pipe section 17 has a slightly smaller diameter than the portion 16A of the pipe and attached end-to-end, as shown in Fig. 2, to the inner surface portion 16A of the pipe. Thus, in the hole where the two parts 16A and 17A of the pipe is erecruit each other, formed region 19.

With these two sections 16 and 17, which are connected to each other through a welded joint 18, the area around the holes that respectively receive effective lining end plates 5. Thus, the end plate 5, which can be made from relatively simple carbon steel can be protected from corrosive or fluid, which otherwise are aggressive. Two sections 16 and 17 are made of sheet metal of a higher quality and with greater corrosion resistance than the end plates 5. Two sections 16 and 17, for example, can be made essentially from a flat sheet of metal that is deeply omitted for the education of the relevant portions 16A and 16b of the pipe. As can be seen from Fig. 2, the sheet metal of the first section 16 has a greater thickness than the second section 17. In the disclosed embodiment, and the flange portion 16b, and the portion 16A of the first pipe section 16 have a greater thickness of material than the relevant portions 17A, 17b of the second leg 17. In the disclosed embodiment, the first section 16, with a greater material thickness, is placed opposite the outer side of the heat exchanger, while the second section 17, with a smaller material thickness, is placed opposite the inner side of the plate heat exchanger, that is, opposite the harbour is in the package inserts. The first section 16 may have a thickness greater than 1.5 mm, and in particular greater than 2 mm, and preferably less than 8 mm, while the second section 17 may have a thickness that is at least 0.5 mm and at most 3 mm, mostly about 1 mm. in Addition, part 17A of the second pipe section is provided in the radial direction inside part 16A of the first pipe section 16 in the hole. Thus, it is allowed that the inner part 17A of the pipe during manufacture was pressed to the outside in the radial direction of the portion 16A of the pipe in connection with the use of a welded joint 18. Under such pressure that can be obtained by means of the clamping element 20, schematically shown in Fig. 3, the air and, thus, gaseous oxygen, can be squeezed from the area where there is a weld connection 18, that is, in the disclosed embodiment, on the outer end portion 17A of the pipe. Due to the greater thickness of the external material in the radial direction of the portion 16A of the pipe a valid use of a relatively large pressing force to the inside in the radial direction of the part 17A of the pipe. Weld connection 18 can be obtained in the disclosed embodiment by means of the device 21 TIG-welding (arc welding tungsten inert gas), which is schematically indicated by the IG. 3. Weld connection 18 appropriately applied to the outer side portion 17A of the pipe, and more exactly, to transition between parts 16A and 17A of the pipe. Weld connection 18 passes essentially around the entire hole. A relatively large material thickness is also of advantage in respect of the application of a welded joint 18, as it reduces the risk of burning.

The flange portion 16b of the first section 16 also includes three vertirosan recesses 22, which pass around the hole. Outside from the outer side flange part 16b is provided with sealing element 23, for example, in the form of a strip. Due to the recesses 22 sealing element 23 can be pressed for a secure and tight joint relative to the flange portion 16b. Outside the sealing element 23 is provided with a flange 24 of the pipe 9. The flange 24 connected end-to-end with the sealing element 23 and is attached to a sealed joint with the help of a number of bolts 25, which screw into the end plate 5.

The invention is not limited to those disclosed by the embodiment, but may be varied and modified within the scope of the subsequent claims claims.

For example, you can provide a site that is directed to the inner side of the plate heat exchanger, a relatively thicker part of the tube and thus provide the IC area, with a relatively thinner portion of the pipe on the outer side of the heat exchanger, and thus that this thinner portion of pipe connected end-to-end to the inner surface of the thicker part of the tube. Then weld respectively applied on the inner end portion of the external pipe section.

In the disclosed embodiment, the flange portion 16b and a portion 16A of the pipe of the first section have the same thickness of material and the flange portion 17b and the part 17A of the second pipe section also have the same thickness of material. Thus, these two pieces can be made in easy way. However, it is also possible to allow the flange part and the part of the respective pipe sections had different thickness. For example, the portion 16A of the first pipe section 16 may have a greater thickness of material than the flange portion 16b of the first section 16.
