Structure design and numerical optimization of thermoelectric fan

Large temperature difference between the upper and the lower zone of the tent exists in cold region for Qinghai-Tibet Plateau, a thermoelectric fan on the top of the heating stove was proposed to improve the temperature uniformity in the above mentioned tent. The air velocity and temperature distribution in the tent were numerically studied under different air mass flow rate. Moreover, the effects of fan geometry parameters on the temperature difference between hot end and cold end for the thermoelectric module were investigated. It is revealed that the employment of thermo-electric fan help to improve the air temperature uniformity significantly. The designed optimized fan structure can successfully satisfy the operating requirement of the temperature difference for the thermoelectric module.
