Abstract

We have built a simply designed cell for the measurement of the thermal conductivity of liquids under steady state conditions from room temperature to about 60 °C. Thermal conductivities measured in the range between 0.2 and 0.7 Wm(-1) K(-1) show deviations of a few percent from reference thermal-conductivity data. The cell is made of two concentric parallel plates separated by a 0.44 mm thick sample. It is easily assembled and loaded with the sample for a quick and routine use.

摘要

我们构建了一个设计简单的单元，用于在室温至约60°C的稳态条件下测量液体的热导率。在0.2至0.7 Wm(-1) K(-1)范围内测得的热导率与参考热导率数据相比，偏差为百分之几。该单元由两个同心平行板组成，中间由一个0.44毫米厚的样品隔开。它易于组装并装入样品，可快速进行常规使用。
