【Abstract】 The heat dissipating problem is becoming more and more severe as the size of electric components is decreasing and the power consumption is increasing. Therefore,thermoelectric coolers(TEC)have attracted a great deal of attention. The present work studied the influences of different working voltage,cold-end loads and the heat transfer coefficients of the hot-end on the cooling performance of TEC experimentally. The results show that there are close relations between the refrigeration performance and the working voltage. Besides,there exists an optimal working voltage for different heat transfer coefficients and loads. The results can provide a reference for the applications of TEC in heat dissipating fields.更多还原
