Embodiment Construction
[0027] The following examples further illustrate the present invention. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, those skilled in the art make various equivalent modifications of the present invention fall within the appended claims of the present application. The limited range.
[0028] The present invention is a light aluminum reflux tube, whose structure is briefly described as a double tube structure, the inner layer structure is a light tube, and the outer layer structure is a microchannel. The refrigerant entering and exiting from the compressor flows from the inner and outer structures of the new pipe, so that the refrigerants of different temperatures exchange heat in the inner and outer layers of the new pipe. It mainly consists of two sections of pipes, an inner pipe and an outer pipe, the inner pipe is sleeved into the outer...

Abstract
The invention discloses a light and efficient aluminum return pipe and a production method thereof. The return pipe comprises an inner pipe body and an outer pipe body. At least one spiral microchannel is formed between the inner pipe body and the outer pipe body. The aluminum return pipe can be obtained through the production method, the inner pipe body enters and comes out of the outer pipe body in a sleeved mode, the inner pipe body and the outer pipe body are connected through brazing, and thus the dimension parameter of the inner pipe body, the dimension parameter of the outer pipe body and the dimension parameters of the microchannels are not affected. The heat transferring effect between the pipe bodies is better, convection of heat transfer media is enhanced, and accordingly plug flow is avoided, and the heat transfer efficiency of the heat transfer media is improved.
Description
technical field [0001] The invention belongs to the technical field of aluminum pipe production, and in particular relates to a return pipe, a suction pipe, a liquid suction pipe and an air suction pipe used for heat exchange on refrigeration and heating equipment. Background technique [0002] Copper has long been used as a structural material for heat exchangers due to its good thermal conductivity. With the advancement of material technology, the technology of replacing copper with aluminum in heat exchangers has become increasingly mature. Compared with copper, aluminum reserves are abundant, the price is 1 / 4 of copper price, and the density is 1 / 3 of copper. The same aluminum structure saves more than 50% of the cost than copper structure. Aluminum instead of copper has obvious economic value. The return pipe / suction pipe / suction pipe / suction pipe (SuctionPipe) of the original refrigerator and other heat exchange equipment is generally composed of two sets of differen...
