Abstract
The utility model belongs to the technical field of household appliance manufacture, and particularly relates to a return air heat exchanger tube and a refrigerator with the return air heat exchange tube. The return air heat exchanger tube comprises a return air tube and a copper capillary tube which is connected in parallel with the return air tube in an axle upward mode, wherein a copper layer covers the outer surface of the return air tube. The copper layer covers the outer surface of the return air tube, and materials with low cost can be adopted by the return air tube itself, and therefore the copper layer which covers the return air tube can ensure good contact between the copper layer and the copper capillary tube, and electrochemistry corrosion probably caused among different metals can be avoided.
Description
Technical field
The utility model belongs to field of domestic appliances manufacture technology, the refrigerator that is specifically related to a kind of return-air heat exchanger tube and has this return-air heat exchanger tube.
Background technology
The return-air heat exchanger tube of refrigerator is a kind of muffler and the same mao of parts that tracheae sticks together that connect the evaporator inlet section that will connect the evaporator outlet end, by the cold of cold-producing medium in the muffler being passed to the cold-producing medium in the capillary, play the effect that improves the refrigerator refrigeration performance.In the refrigeration pipe of refrigerator, because the price of copper product is higher than other material prices such as aluminium, iron far away, so, all adopted material substitution copper such as aluminium, iron as refrigeration parts such as evaporimeter, condensers in order to reduce manufacturing cost.But at the return-air heat exchanger tube, owing in fact muffler and capillary are sticked together heat exchange, and capillary can only preferably adopt copper product because of problems such as technology and quality, at this moment, if adopt the muffler of aluminium matter and copper capillary tube to fit, intermetallic electrochemical corrosion takes place between the copper aluminium tube material easily.
The utility model content
The purpose of this utility model is to provide a kind of return-air heat exchanger tube, and it can avoid the electrochemical corrosion between muffler and the copper capillary tube, and cost is lower.
The purpose of this utility model also is to provide a kind of refrigerator.
In order to realize one of above-mentioned utility model purpose, the utility model provides a kind of return-air heat exchanger tube, comprises muffler and the copper capillary tube that axially goes up and connect along described muffler, is coated with copper layer on the described muffler outer surface.
As further improvement of the utility model, described muffler is made by rustproof aluminum alloy.
As further improvement of the utility model, described rustproof aluminum alloy is an alumal.
As further improvement of the utility model, connect by scolder between described muffler and the described copper capillary tube.
As further improvement of the utility model, described scolder is a tin solder.
For realizing above-mentioned another utility model purpose, the utility model provides a kind of refrigerator, and described refrigerator comprises aforesaid return-air heat exchanger tube.
Compared with prior art, the return-air heat exchanger tube that the utility model provides is by covering copper layer at the muffler outer surface, and muffler itself can adopt lower-cost material, be coated on copper layer on the muffler can guarantee with copper capillary tube between good the contact, avoid contingent electrochemical corrosion between different metal.
Description of drawings
Fig. 1 is the structural representation of the utility model return-air heat exchanger tube one specific embodiment;
Fig. 2 is the schematic cross-section of the utility model return-air heat exchanger tube one specific embodiment.
The specific embodiment
Below with reference to the specific embodiment shown in the drawings the utility model is described in detail.But these embodiments do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in the protection domain of the present utility model.
Join Fig. 1 and Fig. 2, introduce a specific embodiment of the utility model return-air heat exchanger tube, in the present embodiment, this return-air heat exchanger tube 10 comprises muffler 11 and copper capillary tube 12.
Muffler 11 and copper capillary tube 12 in the axial direction and connect, said here " and connecing " can be the connection that comprises physics mode or chemical mode.For example, in some embodiments, muffler 11 and copper capillary tube 12 can be fit together concurrently, be bundled together by the aluminum foil and adhesive tape muffler 11 and the copper capillary tube 12 of fitting that will walk abreast again, again for example, can be by heat-conducting glue with muffler 11 and 12 parallel connections of copper capillary tube; As preferred embodiment, in the present embodiment, connect by scolder 13 between muffler 11 and the copper capillary tube 12, the connected mode that the scolder of employing metal quality connects with respect to other can have stronger bonding strength, and guarantee excellent heat conductivility, can improve the heat exchange efficiency between muffler 11 and the copper capillary tube 12.
Advantages such as further preferably, scolder 13 adopts tin solder, and it has good effect of heat exchange, and is corrosion-resistant.
Be coated with copper layer 111 on the outer surface of muffler 11.So be provided with, muffler 11 and copper capillary tube 12 and the part that connects can simultaneously, can not produced muffler 11 by the lower material of employing cost owing to electrochemical corrosion takes place for metal material different, and the control of realization cost.
The material of muffler 11 can for example adopt iron, and further preferably, in the present embodiment, muffler 11 is made by rustproof aluminum alloy, so can reduce the product weight of return-air heat exchanger tube 10, obtains the etch-proof characteristic of rust-proofing simultaneously.Here said " rustproof aluminum alloy " can be for example to be alumal and/or almag, in the present embodiment, preferably adopt alumal to make muffler 11, compared to almag, alumal adapts to Bending Processing welding more, and has and process intensity preferably.
In specific embodiment more, the structure that covers copper layer on the muffler 11 can specifically adopt the CCA copper aluminum composite pipes, it comprises the copper layer 111 that muffler 11 that 3003 rustproof aluminum alloys make and oxygen-free copper make, rolling between muffler 11 and the copper layer 111 by HTHP, realize interatomic metallic bond combination between muffler 11 and the copper layer 111 thus.The integrated material of the tubing of CCA copper aluminum composite pipes can't separate between copper aluminium, can be as, enlarging crooked as copper pipe, and pliability is identical with copper pipe, and purchase cost is lower.
The utility model also provides the refrigerator that adopts above-mentioned return-air heat exchanger tube 10 (figure does not show), owing to adopted this return-air heat exchanger tube 10, refrigerator can guarantee preferable refrigeration heat exchange effect when reducing manufacturing cost.
The utility model is by above-mentioned embodiment, has following beneficial effect: be provided with by outer surface and coat copper layer 111 at muffler 11, muffler 11 itself can adopt lower-cost material, and be coated on copper layer 111 on the muffler 11 can guarantee with copper capillary tube 12 between good the contact, avoid contingent electrochemical corrosion between different metal.
Be to be understood that, though this specification is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technical scheme in each embodiment also can form other embodiments that it will be appreciated by those skilled in the art that through appropriate combination.
