AI Technical Summary
In existing heat exchangers, the torsion section protrudes from the fin surface, making it difficult to install in products with fixed outer frame dimensions, thus affecting the installation effect of the heat exchanger.
By optimizing the structure of the flat tubes and fins, the torsion section is spaced apart from the first side of the fin, and the flat tubes and fins are stacked alternately. The width and thickness of the flat tubes and fins are adjusted to meet the installation requirements of different product housings.
It improves the heat exchange efficiency and drainage performance of the heat exchanger, while solving the installation difficulties caused by the protruding torsion part, and provides a flexible installation solution.
