[0002] Thermoelectric materials are functional materials that can convert heat energy into electrical energy. The Seebeck effect discovered in 1821 and the Peltier effect discovered in 1834 provide a theoretical basis for the application of thermoelectric energy converters and thermoelectric refrigeration. With the increasing interest in space exploration, the progress of applied physics, and the increasing resource survey and exploration activities on Earth, it is necessary to develop a power system that can supply energy by itself and does not require attention. Thermoelectric power generation is particularly suitable for these applications.
[0003] After the thermoelectric material is processed, it needs to be tested with a testing device. In order to avoid displacement of the thermoelectric material during the test, a clamp is often needed to fix it. However, the surface of the fixing block of the existing clamp is mostly square, and can only fix square thermoelectric materials. When special-shaped thermoelectric materials appear, the square fixing block cannot completely fit with the surface of the special-shaped thermoelectric material, resulting in loose fixation and poor fixing effect, thereby affecting the test results. In order to solve the above problems, a fixing fixture for thermoelectric material testing is proposed. Utility Model Content
