Embodiment Construction

[0011] See attached figure 1 As shown, an aluminum alloy capillary tube 1 has an outer diameter of 1.8mm and a wall thickness of 0.6mm. It is made of 1060 aluminum tubes with a diameter of 5.9mm and a wall thickness of 0.9mm. The equipment is pulled out. One kind of air return pipe always becomes an aluminum alloy return air pipe 2 and the aluminum alloy capillary tube 1 which are wrapped by aluminum foil tape 3.

[0012] Compared with the copper capillary tube, the aluminum alloy capillary tube of the present invention has a low price advantage and a high-efficiency production method. The air return tube of the aluminum alloy capillary avoids the risk of electrochemical corrosion, and the air return tube is extended and the refrigerator using the return air tube life.

[0013] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person familiar with the profession may use the technical cont...

Abstract

The invention relates to the field of refrigeration systems, particularly an aluminum alloy capillary and a return pipe assembly with same. The outer diameter of the aluminum alloy capillary is 1.8 mm with a wall thickness of 0.6 mm; the aluminum alloy capillary is formed by drawing an aluminium pipe, which adopts a 1060 material and has an outer diameter of 5.9 mm and a wall thickness of 0.9 mm, by a drawing device. A return pipe assembly, comprising the aluminum alloy capillary. Compared with a copper capillary, the aluminum alloy capillary provided by the invention has the advantages of a low price and a high-efficient production mode; the return pipe adopting the aluminum alloy capillary avoids the risk of electrochemical corrosion, thus the lifetime of the return pipe and the refrigerator using the return pipe is prolonged.

Description

Technical field [0001] The invention relates to the field of refrigeration systems, in particular to an aluminum alloy capillary tube and an air return pipe assembly with the same. Background technique [0002] The existing air return pipe assembly for refrigerators is mainly composed of an aluminum alloy return pipe and a copper capillary tube wrapped by aluminum foil tape. The return air pipe assembly formed by winding copper and aluminum materials is in actual use. In the humid environment of the refrigerator, electrochemical corrosion is prone to occur, reducing the effective service life of the refrigerator. In addition, the aluminum tube of the same specification is 30% of the quality of copper tube, and the material cost is about 30% of copper. The use of aluminum alloy material can greatly reduce the material cost and give the product a good competitive advantage. Summary of the invention [0003] The present invention aims to solve one of the above-mentioned technical pr...
