温差电材料室温热导率测试装置的研制

RESEACH AND MADE A DEVICE FOR MEASURE THERMAL CONDUCTIVITY OF THE THERMOELECTRI MATERIAL IN ROOM TEMPERATURE

本文介绍了半导体致冷材料在室温条件下热导率测试装置的制作原理及方法。本装置的特点是采用绝对稳态法测试，样品做得薄，侧面散热小．测试误差小．

The principle and methods of making a device for measure thermal conductivity of semiconductor thermoelectric materials were produced in the aniele.The characteristics of the new device are following:the absolute steady-state method for measure was used;the sample was thin:the lost heat on side sids few;the measure crror was little.
