How to determine the number of high-performance heat sink installations

- Jul 11, 2019-

The main form of heat dissipation for high-performance heat sinks is convection, radiation, convection plus radiation, and convection is better than radiation. In order to improve the thermal efficiency of the radiator, the scientific method is to install under the window or on the side of the window, which can effectively prevent the entry of cold air and rapidly heat the cold air entering the room from the window direction. If installed in other locations, consider increasing the heat by 10-20%, that is, increasing the amount of heat sink.

 

When determining the number of high-performance heat sinks, the number of heat sinks should be corrected according to the connection method, installation form, number of assembled pieces, hot water flow, and surface coating. The amount of heat dissipated by the heat sink is determined experimentally under specific conditions.

 

In practical engineering applications, the situation is often varied, and there is a certain difference between the heat dissipation and the heat dissipation given under the test conditions. In addition, the design should be based on different heat transfer temperature differences to select the appropriate heat transfer coefficient. Consider the influence of the connection method, installation form, number of pieces, hot water flow, and surface coating on the amount of heat dissipation.

 

The number of high-performance radiators installed should be compatible with the design load and should not be increased blindly. Blindly increasing the number of radiators not only wastes energy, but also easily causes system thermal imbalance and hydraulic imbalance, which makes the system unable to heat normally.
