Principle
The HCDR-S Thermal conductivity tester uses transient planar heat source technology (TPS), which is based on the principle of transient temperature Response generated by a disc-shaped heat source with step heating in an infinite medium. The Probe is etched from a conductive alloy into a continuous double helix structure sheet, and the outer layer is a double-decked insulating protective layer, which acts as both a heat source and a temperature sensor. During the test, the Probe is placed in the middle of the sample. The current rises by generating temperature, and the heat diffuses to both sides of the sample. The thermal diffusion rate depends on the thermal conductivity characteristics of the material. Thermal conductivity is directly obtained from the mathematical model by recording the temperature and Probe Response Time.
