Reasons Leading to the Decline of Heat Dissipation Efficiency of Finned Tube Radiator

Finned tube radiator is widely used in power, chemical, petrochemical, air conditioning engineering and refrigeration engineering. Its function is to distribute heat through the finned tube, but after a period of time, it will be found that its cooling performance will decline.

Reason 1: finned tube radiator is composed of carbon steel, stainless steel, aluminum finned tube composed of warps and heat exchanger tube composed of heat exchange equipment, because of prolonged use, in the case of higher temperatures, the metal parts are susceptible to corrosion and rust, which will lead to uneven heat dissipation on the surface of the heat dissipation, which is the reason for the decline in efficiency.

Reason 2: the heat exchanger tube is in the steel strip winding steel tube at the same time, the use of high-frequency current skin effect and neighborhood effect, until the plastic state or melting, and then winding welded, if the welding is not good will appear to fall off the loose condition, then it will lead to part of the warping tube can not be carried out normal work, can not dissipate heat.

Reason 3: the internal phenomenon of the warped piece of time, there will be calcified dirt, adhering to the inner wall, seriously affecting the heat dissipation effect of the finned tube radiator.
