The evaporator containing a channel for the refrigerant and place of the pair of the suction pipe, which empties into the suction pipe and is fixed there waterproof, suction pipe put in its place mate. This place is by forming at least generally aligned with the path of the suction pipe. The use of the invention allows to obtain economical and tight connection between the suction pipe and the evaporator. 4 C.p. f-crystals, 4 Il. The invention relates to an evaporator containing a channel for the refrigerant and place of the pair of the suction pipe, which empties into the suction pipe and is fixed there water resistant.The evaporators according to the prior art suction pipe in place of her mates waterproof connected to the evaporator by means of a welded joint. As the welding method is used when this so-called welding tungsten inert gas, and the welding process cannot be managed automatically flowing for both welded parts, in particular, due to fluctuations tolerances and thicknesses of the materials appearing on the plate of the evaporator sledgie manual welding process of the suction pipe with seat mates depending on carrying out the welding process, the employee may happen, that weld will have leaks, which will then be eliminated in most cases by costly improvements.The basis of the invention lies in the task of creating the evaporator according to the restrictive part p. 1 claims simple constructive measures eliminating the disadvantages of the prior art, automated connection between the suction pipe and place her mates.This problem is solved according to the invention due to the fact that the suction pipe is introduced in the place of her mates, and this place mate by forming at least generally aligned with the path of the suction pipe, water resistant which is connected with its mate soldering.Thanks to the solution according to the invention for connecting the connection point with the suction pipe of possible automated, independent contractor process, because the adjustment of the connection point to the path of the suction pipe is formed a definite and uniform solder gap between them, which is due to capillary action draws required to connect both connected elements solder automatically to the connection point. T is emo, so the connection between these two parts is characterized by a high process reliability. In addition, thanks to the solution according to the invention provided is very economical, but nevertheless, with extremely high probability tight connection between the suction pipe and place her mates.In accordance with a preferred form of execution of the object of the invention provides that the processing pressure get two plastic deformation of the material, in place of the pair of the suction pipe is at least approximately opposite to each other.Due to this particularly simple way can be done technologically specific, driven to the external contour of the suction pipe is narrowing its mate.Especially quietly and especially little disturbing process is made of plastic deformation of the material of the evaporator channel for the refrigerant that flows between the two connected plates, if according to the following preferred form of execution of the object of the invention provides that the plastic deformation of material in the plane of the fins of the evaporator protivorechat each other.Particularly simply, for example, in the bulk of the following preferred form of execution of the object of the invention is provided, that plastic deformation of the material obtained relief moulding.Especially suitable plate evaporator is performed, if according to the latest form of the object of the invention provides that the plate evaporator is made by way of rolling and forming channels for the refrigerant is carried out by methods Rollbond" or "Z-Bond".The invention is illustrated in the following description with the aid of embodiments thereof shown in the drawings, which show: Fig. 1 - as a fragment in the front view of the evaporator in the area designated mates, advanced to enter the suction pipe; Fig.2 is a top view of the fragment of the evaporator of Fig.1; Fig. 3 - front view of the fragment of the evaporator of Fig.2 with the throttle tube, water resistant fixed in place mates, corresponding to the door of the suction pipe; Fig.4 is a fragment of the evaporator of Fig.3 in section along the line III-III.In Fig. 1 as the fragment shows a plate 10 of the evaporator is formed by welding two aluminum plates 11, 12, which in this case is made of channel 13 for the refrigerant, made the so-called method "Rollbond". Channel 13 is 14 pair of the suction pipe is obtained by razdachi the marginal zone of the plate 10 of the evaporator, and received 14 mates suction pipe has a lenticular cross-section. 14 pair of the suction pipe is provided with an offset back from the free edge of the plate 10 of the evaporator limiter 15 depth, which is formed by the extended length of 1 place 14 mates suction pipe channel 13 for the refrigerant and is used for insertion is depicted in the form of a segment made of aluminum suction pipe 16. The suction pipe 16, the depth of insertion of which in place 14 of her mates is limited by the stopper 15 is fixed on the plate evaporator 10 by soldering, and before the soldering process after initially having round oval section 14 of the pair is aligned with the outer contour of the suction pipe 16 through a process of relief moulding. To do this, the original, made in the cross-section of the lens 14 of the pair of the suction pipe with a tool like surround stamp way to handle pressure is deformed to form between round in this case, the outer contour of the suction pipe 16 and obtained after the deformation process space 14 of its mating internal circuit kapillyarnogo air gap, which sucks Oia, capillary between moistened flux of connected parts, which prevents the formation of shells in the connection zone between the suction pipe 16 and the seat 14 of her mate. In 14 of the pair of the suction pipe of the aluminum plate 11, 12 plastically deform processing pressure through the relief forming, and plastic deformation of the material lies in the plane of the plate 10 of the evaporator.Unlike evaporator manufactured by the example of the way "Rollbond", the invention is applicable to evaporators manufactured by way of "Z-Bond", and the wire tube evaporators for leakproof connection of the suction pipe 16 with 14 of her mate.
