The object of the present invention is to provide a harmonica shap aluminum tube with large heat exchange area for heat dissipation. The harmonica shap aluminum tube for heat dissipation provided by the present utility model includes a plurality of flow channels formed by a tube wall and a plurality of partition plates, and a plurality of tooth grooves are provided on the tube wall to increase the over-flow area in the tube. As the utility model is provided with a plurality of uniformly distributed tooth grooves on the pipe wall, the surface area in the pipe is increased, the over-flow area between the pipe inner wall and the cooling medium is greatly increased, thereby increasing the heat exchange area of the pipe itself. , Is conducive to improving heat exchange efficiency. At the same time, protruding ribs are correspondingly formed between each of the tooth grooves, which play the role of reinforcing ribs, improve the structural rigidity of the pipe body, increase mechanical stability, and make the utility model harmonica shap aluminum tube better in large scale. Solar energy application systems and other industries have been applied.
