Several reasons for the poor heat dissipation performance of finned tube heat exchangers

Finned tube heat exchangers are several common heat exchangers, the function of which is to dissipate heat through finned tubes, but after a period of use, we will find that its heat dissipation performance will decline, so let's analyze what The situation will cause the efficiency of the heat sink to decrease.

Reason 1: The finned tube heat exchanger is a heat exchange device composed of warped fins and heat exchange tubes composed of carbon steel, stainless steel, and aluminum finned tubes. Because of long-term use, in the case of high temperature, metal Components are susceptible to corrosion and rust, which can cause uneven heat dissipation on the heat dissipation surface and cause inefficiencies.

Reason 2: The heat exchange tube uses the skin effect and proximity effect of high-frequency current when the steel strip is wound around the steel tube until it is in a plastic state or melted, and then wound and welded. If the welding is not good, it will fall off and become loose. , then some of the warping tubes will not work properly and will not be able to dissipate heat.

Reason 3: When the internal event of the warped film is long, calcified dirt will appear, which will stick to the inner wall, which will seriously affect the heat dissipation effect.
