Problems solved by technology

[0002] At present, the filter assembly in the existing technology is to connect the branch pipe to the filter by welding, and the welded part needs to overlap by 10~20mm, so that the welded part is easy to break, especially when it is heated and bent, it is more likely to break, causing leakage hazards and environmental protection problems. At the same time waste of raw materials, short service life

Embodiment Construction

[0014] according to figure 1 As shown, a filter assembly for an air conditioner / refrigerator of the present invention includes a branch pipe I1, a filter 2, and a branch pipe II3, and the side of the filter 2 near the branch pipe I1 is provided with a filter screen, and the branch pipe I1, filter 2, Branch pipe II3 is an integral component.

[0015] The branch pipe I1, the filter 2 and the branch pipe II3 of the present invention are copper tubes, and the filter screen is stainless steel.

[0016] A kind of manufacturing process of air conditioner / refrigerator filter assembly of the present invention, comprises the following steps:

[0017] a) First, make the round tube into the required diameter, wrap the top of the filter screen with copper skin and send it into the round tube, radially spin grooves on the outer diameter of the round tube at the corresponding position of the filter screen, and fix the top of the filter screen;

[0018] b), and then spinning and drawing the...

Abstract

The invention relates to a filter component for an air conditioner/a refrigerator and a manufacturing process thereof. The filter component comprises a branch pipe I (1), a filter (2) and a branch pipe II (3), wherein a filtering net is arranged on one side, which is close to the branch pipe I (1), inside the filter (2); the branch pipe I (1), the filter (2) and the branch pipe II (3) are an integrated assembly. The filter component disclosed by the invention is used for filtering and conveying liquid, impurities in refrigerant media are effectively filtered, welding between the branch pipes and the filter is not needed, the filter component is difficult to break, and the service life is prolonged. The integrated assembly is formed by spinning drawing, the wall thickness, length and shape of any branch pipe can be optionally changed, rapid and integrated product molding can be realized by adopting high-strength materials and matching with self-designed molds, and the refrigerant leakage problem is solved.

Description

technical field [0001] The invention relates to the field of primary refrigeration, in particular to a filter assembly for an air conditioner / refrigerator and a manufacturing process thereof. Background technique [0002] At present, the filter assembly in the existing technology is to connect the branch pipe to the filter by welding, and the welded part needs to overlap by 10~20mm, so that the welded part is easy to break, especially when it is heated and bent, it is more likely to break, causing leakage hazards and environmental protection problems. Raw materials are wasted simultaneously, and the service life is short. Contents of the invention [0003] In view of the above defects, the present invention provides an integrated air conditioner / refrigerator filter assembly and its manufacturing process, which does not require welding, and the filter and branch pipes are formed into an integral assembly by spinning and drawing, which simplifies the process and does not cau...
