Working principle:
Transient planar heat source technology (TPS) is a new method for measuring thermal conductivity, developed by Professor Silas Gustafsson of the University of Technology, Chalmer, Sweden, based on the hotline method. Its principle of determining the thermal properties of a material is based on the transient temperature response produced by a step-heated disk-shaped heat source in an infinite medium. A flat probe is made of a thermally resistive material, and serves as both a heat source and a temperature sensor. The thermal resistance coefficient of the alloy has a linear relationship with the relationship between temperature and resistance. That is, the heat loss can be known by understanding the change of the resistance, thereby reflecting the thermal conductivity of the sample.The continuous double-spiral structure sheet formed by etching after gold etching has a double-layer insulating protective layer and a thin thickness, which makes the probe have a certain mechanical strength and maintain electrical insulation from the sample. During the test, the probe was placed in the middle of the sample for testing. When the current passes through the probe, a certain temperature rise occurs, and the generated heat is simultaneously diffused to the samples on both sides of the probe. The speed of thermal diffusion depends on the heat transfer characteristics of the material. By recording the temperature and the response time of the probe,The thermal conductivity can be directly obtained from the mathematical model.
Testing object:
Metal, ceramic, alloy, ore, polymer, composite, paper, fabric, foam (surface-level insulation, sheet), mineral wool, cement wall, glass reinforced composite board CRC, cement polystyrene board, sandwich Concrete, FRP panel composite panels, paper honeycomb panels, colloids, liquids, powders, granules and paste solids, etc., have a wide range of test objects.
