摘要

为精确测量大功率电子模块内部热阻，研制了一种热测试仪。该测试仪设计用于同时测量20个电子模块，每个模块的功耗超过200w。散发的热量通过每个试验场专用的水冷板传递到环境中。介绍了该测试仪的系统布局、安装装配、系统液压设计、冷板铺布机设计和数据采集仪表。还讨论了样品测量和相关的不确定度。通过与热模拟的对比，验证了样品的计算结果。

Advanced thermal tester for accurate measurement of internal thermal resistance of high power electronic modules

A thermal tester has been developed for the accurate measurement of the internal thermal resistance of high-power electronic modules. The tester is designed for the simultaneous measurement of 20 electronic modules each dissipating in excess of 200 W. The heat dissipated is transmitted to the ambient by water-cooled cold plates dedicated to each test site. The tester system layout, mounting assembly, system hydraulic design, cold-plate spreader design and data acquisition instrumentation are described. Sample measurements and the associated uncertainty are also discussed. The sample results are verified by comparison with thermal modeling.
