The purpose of this study is to improve the cooling performance of a cosmetic refrigerator using a thermoelectric module combined with a pulsating heat pipe. The pulsating heat pipe was used as a heat spreader and a heat sink for a thermoelectric module. Heat was absorbed and dissipated by combined the heat sink equipped with fans. Experiments with a 1 thermoelectric module (5.3 A/15.4 V, size: 40×40×4 ㎜) and a pulsating heat pipe (working fluid charging ratio, etc.) were performed. For the thermoelectric cooling system with a pulsating heat pipe, the temperatures in the cosmetic refrigerator are recorded and then compared with those of lumped system analysis. The results indicates that cooling capacity increases as temperature difference between hot and cold surface decreases.

This study was performed to develop a dryer for home clothes using thermoelectric module. The thermoelectric module was used as a heat source and a dehumidification device because it has heating part and cooling part at once. To design for maximizing the energy efficiency and the rate of dehumidification, the parameters of the dryer using thermoelectric module are heat capacity and air flow rate. This study showed that the thermoelectric module can be used in the clothes dryer and energy efficiency of clothes dryer be better than that of electric heating dryer.
