【Abstract】 The efficiency of semiconductor refrigeration depends on the temperature difference between the cold and hot sides of a thermoelectric couple. This temperature difference can be remarkably reduced both by enhancing the heat loss of the hot side and enhancing the cold dissipation of the cold side, thus leading to the rise of semiconductor refrigeration efficiency. The law of variation in temperature of hot side, which is cooled by water and fan, is tested under the different working conditions. The experimental results provide a basis for optimizing design for the semiconductor refrigeration.更多还原
