摘要
发热器件通过与散热器表面接触,将温度迅速传递到大面积的散热翅片上,然后由翅片间高速的常温气流吸收后带走,形成一条散热通道,保证发热器件在工作中始终处于适宜的器件温度。通过不断优化设计风冷散热器的翅片参数,如:翅片厚度,翅片高度,翅片长度等来寻找到理想的设计参数,并以此来提高风冷散热器的散热效果,以便能在减小风冷散热器体积的情况下获得相似的散热效果,提高整个电子设备的功率密度。
Heat energy produced by the heating device is transferred through the interface between the heating device and the surface of heat sink, and then it is taken away from the fin by cold air. This heat transfer passage ensures suitable temperature environment for the heating device. We can find the ideal dimension of the fin to improve the cooling effect of the sink and the power density by optimizing the design parameters, so as to reduce the size of the heat sink in the same cooling effect.
