Abstract

The utility model relates to an air return tube module of a refrigerator, which is characterized in that the utility model uses a steel air return tube and a copper capillary tube, wherein the air return tube and the capillary tube are arranged in parallel and are welded by solder. Through the use of the steel air return tube, the utility model can not only guarantee heat-transferring effect, but also reduce the cost of the air return tube module.

Description

Refrigerator muffler assembly
Technical field:
The utility model relates to the refrigerator refrigeration system member, the refrigerator muffler assembly of more specifically saying so.
Background technology:
In refrigerator refrigeration system, need reduce temperature capillaceous by means of the low temperature of muffler, specific practice is that muffler and capillary are welded together, and carries out the heat conduction with being in contact with one another between its tube wall.In order to guarantee that welding effect often all is that muffler and capillary all are adopted as copper pipe, this mode has strengthened the assembly cost.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of refrigerator muffler assembly that can suitably reduce cost being provided.
The technical scheme that the utility model technical solution problem is adopted is:
The utility model adopts steel muffler and copper capillary, and described muffler and capillary parallel arranged are welded to connect therebetween.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The utility model can guarantee heat-transfer effect by adopting the steel muffler, can reduce the cost of muffler assembly again.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 section structure schematic diagram.
Number in the figure: 1 muffler, 2 capillaries, 3 scolders.
The specific embodiment:
Referring to accompanying drawing:
Present embodiment adopts steel muffler 1 and copper capillary 2, and muffler 1 and capillary 2 parallel arranged are welded to connect with scolder 3 therebetween.
Between steel pipe and copper pipe, implement welding, can adopt common process.
In welding process, in steel pipe, produce oxide layer, thereby in pipe, form impurity, influence the whole system refrigeration.At the version of present embodiment, when welding, can take the corresponding protection measure, specific practice can be the closed at both ends with muffler 1, has charged into nitrogen in it, welding gets final product muffler 1 emptying after finishing again.
