摘要

本文以功率二极管附在散热器上为例，讨论了自由对流冷却电子系统的传热系数温度依赖问题及其重要性。该系数的平均值是通过对不同器件加热电流下的器件冷却曲线的多次测量来估计的。然后用这些值用紧凑的热模型对器件进行瞬态模拟。

Estimation of heat transfer coefficient temperature dependence from cooling curve measurements

This paper discusses on the practical example of a power diode attached to a heat sink the problem of heat transfer coefficient temperature dependence and its importance for free convection cooled electronic systems. The average values of this coefficient are estimated from multiple measurements of device cooling curves performed for different device heating currents. These values are used then for transient simulations of the device with compact thermal models.
