Radiator Fin Height and Quantity

August 14, 2023

To improve the heat transfer effect of radiators, the selection of radiators should pay attention to the following issues:

1) In order to ensure the structure compactness, the radiator structure should meet the volume, weight and shape requirements of the overall design.

2) In the actual heat exchange process, the temperature distribution of the radiator substrate is uneven. The temperature at the installation location of the power component is higher than that at other locations, and the temperature at the air outlet is higher than the temperature at the air inlet. Reasonable distribution on the radiator substrate to ensure uniform temperature distribution and prevent thermal coupling between power components, it is necessary to select a radiator of appropriate width and length in the calculation results, and arrange the radiators reasonably;

3) Increasing the height and number of radiator fins can increase the heat transfer efficiency of the heat exchanger structure, but the increase in the radiator fin quantity will also increase the wind resistance of the air duct, which will reduce the heat dissipation effect. The effect improvement is not obvious. Therefore, it is impossible increase the number and height of radiator fins indefinitely.
