Abstract

The invention discloses a lifting type heat conductivity coefficient testing instrument of a constant-temperature water tank, and aims to adopt an automatic lifting device to facilitate taking and placing during a test, adopt a constant-temperature water tank to more conveniently control the temperature difference between a cold plate and a hot plate in the test process, and further ensure that heat flow is uniformly transferred in a test piece; the flow and the temperature of a water inlet and a water outlet of a core part of the cold plate are measured, so that the heat taken away by water is obtained, the one-dimensional steady-state power of the test piece is more accurate when the heat conductivity coefficient is calculated, the test result is more accurate, and the automation of an instrument is improved. For further making the measurement result better, an attractive visual interface is set by using LABVIEW. The testing instrument can accurately measure the heat conductivity coefficient of the test piece, and is simple and convenient to operate.

Description

technical field [0001] The invention relates to the field of thermal conductivity testing instruments for materials, in particular to a lifting type thermal conductivity testing instrument for a constant temperature water tank. Background technique [0002] Thermal conductivity is a key parameter for the performance of thermally conductive materials, which refers to the amount of heat transferred through a unit area of ​​a material within a certain period of time under stable heat transfer conditions. Generally speaking, the higher the thermal conductivity, the better the performance. Therefore, in order to obtain the various performance parameters of the material to accurately locate the specific use of the material, it is very important to measure the thermal conductivity of the material. [0003] At present, there are theoretical methods and experimental methods to obtain thermal conductivity. The theoretical method to obtain the thermal conductivity is mainly obtained b...
