采用当量热流通道的概念对接触热阻的预测进行简化分析，即对表面情况建立相应的表面模型后，确定出当量热流通道上的各个参数，整个接触面上的接触热阻即可视为有多个当量热流通道形成的接触热阻并联而成，从而可以预测出两个物体间的接触热阻。
The concept of equivalent heat flow channel is adopted to simplify the prediction of contact thermal resistance. After establishing the corresponding surface model of the surface, the parameters of the equivalent heat flow channel are determined. The contact thermal resistance of the entire contact surface can be regarded as Multiple equivalent heat flow path formed by the contact resistance in parallel, which can predict the thermal contact resistance between two objects.
