主要功能及特色
TPS 2500S（厂商：瑞典Hot Disk AB）的测量原理基于瞬态平面热源法：TPS，即Transient Plane Source Method。在本方法中，探针是一个平面探头，系由导电金属镍经蚀刻处理后形成的双螺旋结构的薄片，外层由厚度25微米的聚酰亚胺（Kapton）覆膜保护。探头通常被置于两片样品中间进行测试，Hot Disk提供了不同尺寸的探头供选择，可同时测得导热系数和热扩散系数(符合ISO/DIS 22007-2标准)。TPS 2500 S适用于不同类型的材料，包括固体、液体、粉末和复合材料等。
测试过程中，电流通过探头时产生热量，热量同时向探头两侧的样品进行扩散，热扩散的速度依赖于材料的热传导性能。通过记录温度与探头的响应时间，材料的热导系数，热扩散系数被计算出来。
The TPS 2500S (manufacturer: Hot Disk AB, Sweden) utilizes the Transient Plane Source (TPS) method for measurement. The probe consists of an etched nickel double-spiral structure, protected by a 25-micron thick polyimide (Kapton) film. It is typically placed between two sample pieces for testing. Hot Disk offers probes in various sizes for simultaneous measurement of thermal conductivity and thermal diffusivity, compliant with ISO/DIS 22007-2 standards. The TPS 2500S is suitable for a variety of materials, including solids, liquids, powders, and composites.
During testing, an electric current generates heat in the probe, which then diffuses into the samples. The rate of thermal diffusion is dependent on the material's thermal properties. By recording the temperature response and the probe's reaction time, the thermal conductivity and thermal diffusivity of the material are calculated.
