Abstract

The invention discloses a heat exchange inner thread pipe and a production method thereof. Spiral threads are arranged on the inner wall of the inner thread pipe, and thread teeth of the same spiral thread are up-and-down wavy. The inner surface area of the inner thread pipe is further increased, the heat exchange efficiency is improved, and meanwhile, since the heights of the thread teeth of the single spiral thread are different, the circulation of a heat transfer medium is subjected to interference, and the heat transfer efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of heat exchange pipes, in particular to a design and production method of an internally threaded pipe. Background technique [0002] Due to good thermal conductivity, copper and aluminum alloy light pipes have been used as structural materials for heat exchangers. With the advancement of material technology, heat exchanger structural materials such as copper internal thread pipe, aluminum internal thread pipe, copper-aluminum composite pipe, and copper-aluminum composite thread pipe have appeared. As a high-end product, the ordinary internal threaded pipe has grooves on the inner wall and the groove has a helix angle. The inner wall of the inner pipe is used to contact the refrigerant to absorb heat, and the outer aluminum pipe is used for heat dissipation. Compared with bare pipes, ordinary internal threaded pipes use grooves on the inner wall to increase the heat transfer area and improve heat transfer e...
