AI Technical Summary
In high humidity environments, traditional finned tubes suffer from reduced heat exchange efficiency due to liquid film buildup, and the insufficient connection strength between the fins and the heat exchange tubes also affects heat transfer performance.
It adopts an inclined fin structure with an angle of 30°-45° between the fins and the axis of the heat exchange tube. The fin roots are provided with L-shaped feet that are fixed by brazing. The material is copper or aluminum, and the fin thickness is 1-2mm. It is designed to be wrapped around the outside of the heat exchange tube in a strip shape.
In high humidity environments, droplets do not accumulate on the fin surface, enhancing heat exchange efficiency and improving the heat transfer performance and connection strength of the fins.
