Abstract
The invention relates to an evaporator with a cooling means canal arrangement and a suction pipe connection point, in which a suction pipe runs into and is liquid tight at that location. The suction pipe is guided into the suction pipe connection point and said connection point is adapted to the contour of the suction pipe to the greatest extent by shaping without tension.
Description
Technical field
The present invention relates to have the vaporizer of coolant channel structure and suction pipe interface, wherein suction pipe be communicated with vaporizer and fluid-tight be fixed on the vaporizer.
Background technique
In existing vaporizer, the suction pipe jointing with the welding mode with suction pipe and vaporizer fluid-tight link together.Wherein the welding method of Cai Yonging is so-called tungsten-inert gas shielding-welding (Wolfram-innertgas-Schweisse); this moment is particularly because because of carrying out the sum of errors material thickness variation can occurring when suction pipe connects on evaporator plate, so can't will be that basic welding process is controlled as automatic operating process to weld two parts by means of expansion.Because can thereby make welded joint the space occur because of the former of the workman that finishes welding process with the welding process of manually finishing that suction pipe is soldered to the suction pipe interface of vaporizer, the expense of both expensive be wanted in the repairing in these spaces usually.
Summary of the invention
The objective of the invention is, in described vaporizer, overcome shortcoming in the prior art, realize the connection between suction pipe and the suction pipe interface automatically with simple structural measure.
The objective of the invention is to realize in the following manner, that is, suction pipe is inserted in the suction pipe interface, and process the profile that makes suction pipe interface adaptation suction pipe, by welding suction pipe and suction pipe interface are linked together again by chipless.
By scheme of the present invention, the workman can oneself control Manufacturing Automated process when the suction pipe interface is connected with suction pipe, determine and uniform weld seam owing between two parts, form, so can on connection mouth, automatically draw the scolder that two connected elements are connected together and need by capillarity.Can guarantee that in this way suction pipe interface and suction pipe do not have shrinkage cavity defect and realize that fluid-tight ground links to each other, so the connection between two parts has higher process Security.In addition, by scheme of the present invention, between suction pipe and suction pipe interface, formed very low but the connection of cost with high sealing.
Be provided with two plastic material deformable members that form by chipless machining with the corresponding preferred embodiment of theme of the present invention, described deformable member is relative at the suction pipe jointing at least haply.
Therefore can form the suitable restriction of the suction pipe interface that causes by the manufacturing process of determining with simple especially technology and mode to the suction pipe external frame.
If another preferred embodiment according to the inventive subject matter is arranged to make it words respect to one another with the plastic material deformable member in the evaporator plate plane, the plastic material deformable member is small especially to the influence that the vaporizer that has the coolant channel structure of extending between two plates that are connected with each other brings, and the influence that production technology is caused is especially little.
If another preferred embodiment of theme of the present invention forms the plastic material deformable member by punching press, especially simply is for example can form the suction pipe interface that narrows down that causes by the chipless moulding in mold.
If another preferred embodiment according to theme of the present invention is manufactured plate type evaporator with roll extrusion joint (Rollbond) or Z-shaped joint (Z-Bond) method, then can make specially suitable plate type evaporator.
Below by in conjunction with the accompanying drawings the brief description that embodiment did being further described the present invention.

Fig. 2 is the partial top view of vaporizer shown in Figure 1,
Fig. 3 is the partial elevation view of vaporizer shown in Figure 2, have on the vaporizer convection cell be fixed on hermetically and suck in the suction pipe interface that the mouth of pipe adapts throttle pipe and
Fig. 4 is the local figure of vaporizer that amplifies along the part of cutting line III-III among Fig. 3.
Embodiment
According to Fig. 1, it shows the partial view of evaporator plate 10, evaporator plate 10 constitutes by welding two thin aluminum sheets 11,12 of the same area, in the case, a coolant channel 13 that forms by so-called roll extrusion bonding method (rollbond) is arranged in above-mentioned thin plate.Coolant channel is provided with suction pipe interface 14, this interface is by the mouth that expands, for example be formed on the fringe region of evaporator plate 10 by so-called locally expanded on the coolant channel made from the roll extrusion bonding method 13, wherein the suction pipe interface 14 of Xing Chenging has the cross section that is similar to lens.Suction pipe interface 14 is provided with the degree of depth limiting component 15 that returns certain distance from evaporator plate 10 free ends, this degree of depth is coolant channel 13 forms hole enlargement place towards capillary interface 14 a length L, and this degree of depth can be used for inserting capillary tube made of aluminum 16, only shows one section suction pipe among the figure.The suction pipe 16 that insertion depth in suction pipe interface 14 is limited by degree of depth limiting component 15 is fixed by welding on the evaporator plate 10, wherein before welding process, the suction pipe interface 14 that has oval cross section originally after the hole enlargement operation adapts by the external frame of punching press and suction pipe 16.Therefore, by the workpiece that constitutes with mold suction pipe interface 14 chipless machining that have similar lens cross section are originally become to make it to form air gap at the current circular external frame of suction pipe 16 with between by the interior profile that suction pipe interface 14 is processed to form, described air gap is used between the connected element that soaks into solder flux and draws to weld the scolder 17 that uses between suction pipe 16 and suction pipe interface 14 as the capillary tube, has therefore avoided shrinkage phenomenon occurring on the join domain between suction pipe 16 and the suction pipe interface 14.Go out aluminium sheet 11 and 12 by chipless machining Plastic Forming on suction pipe interface 14 of carrying out by means of punching press, wherein in the plane of evaporator plate 10, form the plastic material deformable member.
Except producing with the roll extrusion bonding method the example of vaporizer, for suction pipe 16 and suction pipe interface 14 fluid-tight ground are connected together, the present invention can also adopt vaporizer and the pipe-coil type evaporator that utilizes the production of Z bonding method.
