Abstract
The utility model discloses an air returning pipe assembly and a refrigerator, which are applied to refrigeration equipment, wherein a connecting pipe is fixed on the outer side of an air returning pipe of the air returning pipe assembly; a capillary pipe is embedded in the connecting pipe; and an anti-corrosion layer is arranged on the surface of the connecting pipe. According to the air returning pipe assembly disclosed by the utility model, abrasion problem between the capillary pipe and the air returning pipe is avoided, and corrosion between the connecting pipe and the capillary pipe and the air returning pipe is also prevented. The refrigerator employing the air returning pipe assembly is enhanced in reliability.
Description
Technical field
The utility model relates to a kind of appliance field, especially a kind of muffler assembly and use the refrigerator of this muffler assembly.
Background technology
Refrigerator refrigeration system mainly is made up of parts such as compressor, condenser, evaporimeter, muffler, capillaries.In order to make the cold-producing medium in the capillary cold excessively, improve the efficient of refrigeration system, often adopt the method for the parallel heat exchange of capillary and muffler, constitute the muffler assembly.When adopting copper capillary, as protect improperly, be prone to the generation etching problem with aluminium matter muffler.
The utility model content
The technical problem underlying that the utility model will solve is, a kind of muffler assembly and refrigerator are provided, and etching problem can not take place between its capillary and the muffler.
For solving the problems of the technologies described above, the utility model provides a kind of muffler assembly, comprises capillary and muffler, and the said muffler outside is fixed with tube connector, and capillary is embedded in the tube connector; Said tube connector surface is provided with anticorrosive coat.
Said tube connector contacts with the muffler face, and capillary sectional dimension and tube connector inner cavity size are adaptive.
Said capillary sectional dimension and tube connector inner cavity size are adaptive, refer to the capillary cross section for circular, and it are the inscribed circle in tube connector cross section.
Tube connector is an aluminum pipe, and anticorrosive coat is an alumina layer.
Said capillary is a copper pipe.
Said muffler is an aluminum pipe.
The surface of said tube connector comprises its inner surface and outer surface.
Also comprise heat-shrinkable T bush, said heat-shrinkable T bush coats capillary, tube connector and muffler simultaneously.
A kind of refrigerator comprises refrigeration system, adopts as aforesaid a kind of muffler assembly in the said refrigeration system.
The beneficial effect of the utility model is: a kind of muffler assembly and refrigerator; Wherein, The muffler outside of muffler assembly is fixedly connected pipe, and capillary is embedded in the tube connector, and the tube connector surface is provided with anticorrosive coat; Avoided the etching problem between capillary and the muffler, and also can not corrode between tube connector and capillary and the muffler.Adopt the refrigerator reliability of this muffler assembly to improve.
Further, tube connector contacts with the muffler face, has guaranteed that capillary and muffler combine reliably, heat transfer performance gets a promotion, thereby has improved refrigerator refrigerating efficiency, reduction refrigeration cost.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model muffler assembly;
Fig. 2 is the enlarged drawing of Fig. 1 vertical view.
The specific embodiment
Combine accompanying drawing that the utility model is done further explain through the specific embodiment below.
As depicted in figs. 1 and 2, a kind of embodiment of muffler assembly comprises capillary 1 and muffler 2, is fixed with tube connector 3 in muffler 2 outsides, and capillary 1 is embedded in the tube connector 3; Tube connector 3 is that the surface is the aluminum pipe of alumina layer.Tube connector 3 contacts with 2 of mufflers, and capillary 1 sectional dimension and tube connector 3 inner cavity sizes are adaptive.Usually capillary 1 can adopt copper pipe, and muffler 2 can adopt aluminum pipe, and in this programme, because the aluminium oxide stable chemical performance, copper pipe does not directly contact with aluminum pipe, so mutual corrosion can not take place.And capillary 1 and muffler 2 have strengthened the heat exchange effect for face contacts.
Concrete, said capillary 1 sectional dimension and tube connector 3 inner cavity sizes are adaptive, refer to capillary 1 cross section for circular, and it are the inscribed circle in tube connector 3 cross sections.
The surface of said tube connector 3 comprises its inner surface and outer surface.
When implementing, tube connector 3 is can be the body of other material, and its surface is provided with corresponding anticorrosive coat and gets final product.
When implementing, also can comprise heat-shrinkable T bush, said heat-shrinkable T bush coats capillary 1, tube connector 3 and muffler 2 simultaneously.Play the effect of fastening muffler 2 and capillary 1.
With reference to Fig. 1,2, a kind of refrigerator comprises refrigeration system, in refrigeration system, adopts as aforesaid a kind of muffler assembly.Thereby make reliability raising, the refrigerator refrigerating efficiency of refrigerator improve, reduce the refrigeration cost.
Above content is the further explain that combines concrete embodiment that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
