Title:
TEC HIGH-LOW TEMPERATURE IMPACT TESTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/244215
Kind Code:
A1
Abstract:
A TEC high-low temperature impact testing machine, comprising a cooling heat-dissipating mechanism, a semiconductor refrigeration plate (6), and a controller (8). The cooling heat-dissipating mechanism comprises a variable speed compressor (1), a condenser (2), and an evaporator (5). A hot surface of the semiconductor refrigeration plate (6) is in contact connection with the evaporator (5), and a cold surface of the semiconductor refrigeration plate (6) is in contact connection with a heat conducting member (7). The controller (8) is electrically connected to the semiconductor refrigeration plate (6) and the variable speed compressor (1) to control, by means of a received system parameter, positive and negative electrodes and the magnitude of voltage of the semiconductor refrigeration plate (6) and the refrigeration capacity of the variable speed compressor (1). The testing machine has a low refrigeration temperature, can reach a temperature ranging from -70°C to 150°C, and thus features a high refrigeration speed and large refrigeration capacity, simple operations, a small volume, and low consumption and is energy-saving and environmentally friendly. During a test, temperature adjustment can be performed for an individual element without affecting a test circuit, thus greatly prolonging the service life of a test circuit; in addition, during a test process, pressure and temperature are both effectively controlled.
