摘　　要：本文研究了反映材料导热性能的导热系数的测试方法与系统。针对现有导热测试设备体积大,只能测量样品导热系数,测试结果不准确等缺陷,设计一种以平板作为监测终端的便携式导热测试仪。系统基于STM32控制器检测样品质量、厚度、温度曲线以测量导热系数,同时将图片或者数据文件形式存储于平板的测试主机,方便后期处理。检测过程中,系统动态调整压力,降低受温度影响导致的样品膨胀等误差影响,实验平台上显示系统能准确测试导热系数,运行稳定。The test method and system of thermal conductivity to reflect the thermal conductivity of materials are stud- ied. For the existing thermal test equipment, large volume, can only measure the thermal conductivity of the sam- ple, the test results are not accurate and other defects, the design of a flat as a monitoring terminal portable thermal conductivity tester. System based on STM32 controller to detect sample quality, thickness, temperature curve to measure the thermal conductivity, while the picture or data file format stored in the flat test host, to facilitate post- processing. During the testing process, the system dynamically adjusts the pressure and reduces the influence of tem- perature caused by temperature expansion. The experimental platform can accurately test the thermal conductivity and stable operation.
