Copper pipes for refrigerators

Abstract

The invention discloses a copper pipe for a refrigerator, which comprises an air inlet pipe, a copper pipe body and an air outlet pipe connected in sequence. The outer wall of the copper pipe body is provided with a spiral chute, and the outer wall of the copper pipe body is sheathed Limiting ring, the inner wall of the limiting ring is provided with two first storage slots arranged in parallel, the first storage slot is an annular structure, the first storage slot is coaxially arranged with the copper pipe body, and the outer wall of the limiting ring is provided with Inverted T-shaped second storage slot, the two first storage slots are connected with the second storage slot, the inside of the second storage slot is slidingly connected with a ring-shaped limiting plate, and both ends of the inner wall of the limiting plate are fixed with ring-shaped As for the connecting plate, the two connecting plates are respectively located in the two first storage slots. The invention fixes the copper pipe body firmly, and the refrigerator is working, which reduces the possibility of shaking of the copper pipe body, reduces the noise generated by the refrigerator, facilitates the defrosting treatment of the copper pipe body, and is designed to facilitate leakage of the copper pipe body for preliminary testing.

Description

technical field [0001] The invention relates to the technical field of copper tubes, in particular to copper tubes for refrigerators. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. [0003] At present, refrigerators usually use copper tubes as heat exchange tubes to cool down the storage space inside the refrigerator. However, when traditional copper tubes are used, the copper tubes are not fixed firmly. When the refrigerator is working, the copper tubes shake, and the increased refrigerator Noise, and after long-term use, copper pipes are prone to leaks, and the leaks are inconvenient to detect, which brings great inconvenience to people's use.
