AI Technical Summary

Technical Problem

In existing heat exchangers, the heat transfer efficiency of the connecting pipes is low, which affects the heat exchange efficiency, and the connection method needs to be improved to enhance stability and heat dissipation.

Method used

A high-efficiency heat exchange fin is designed, which adopts a corrugated fin body, with a threaded protrusion and a cutting edge on the connecting pipe, and an auxiliary pipe threadedly connected to the connecting pipe. The overlapping plate fits with the fin, increasing the heat exchange area and reducing wind resistance. The auxiliary pipe and the connecting pipe are integrally formed, and the threaded structure extends the interaction time between the air and the auxiliary pipe.

Benefits of technology

It increases the heat exchange area and heat dissipation efficiency, reduces wind resistance, enhances connection stability, and improves the heat conduction effect between copper tubes and fins.

Abstract

The utility model discloses an efficient heat exchange fin, which belongs to the technical field of heat exchangers and comprises a fin body and connecting pipes connected to the fin body, the fin body is of a wave-shaped structure and is provided with a wave crest part and a wave trough part, and the wave crest part and the wave trough part are fixedly connected with a plurality of connecting pipes in a penetrating manner. Auxiliary pipes are fixedly installed at the two opposite ends of the connecting pipe, the two ends of each auxiliary pipe are through and communicate with the connecting pipe, the auxiliary pipes and the connecting pipe are used for allowing a copper pipe to pass through, protruding parts are arranged on the outer walls of the auxiliary pipes and are of a threaded structure, and blade angles are arranged on the sides, away from the auxiliary pipes, of the protruding parts. According to the efficient heat exchange fin, the heat conduction effect of the connecting pipe is enhanced, and more heat around the connecting pipe can be taken away. The utility model further provides a heat exchanger with the efficient heat exchange fin.
