Description

Technical Field

[0001] The utility model relates to the technical field of copper headers, in particular to a double-return copper header. Background Art

[0002] Copper headers are a collection of copper tubes, which are composed of a large number of copper tubes. Copper headers are often used in refrigeration equipment, such as air conditioners, refrigerators, freezers and other home appliances. Copper headers are mainly responsible for transporting liquids such as water and refrigerants, and transporting them to the working position evenly and quickly.

[0003] However, with the increase in usage demand, the single-return copper header is gradually unable to meet the needs of users, and the existing double-return statistical pipe has relatively simple functions. When in use, it is introduced through pipeline A and then exported through pipeline B. It has great limitations when in use, and the structure is simple and cannot adapt to the connection of a variety of different pipelines. In order to solve the above problems, while using a single tube to achieve double returns, it is convenient to connect pipelines of different diameters according to needs, thereby improving its scope of application and universality. For this reason, we propose a double-return copper header. Utility Model Content
