열전소자와 PF Type 진동형 히트파이프를 이용한 냉ㆍ난방기에 관한 연구

The purpose of this study was to develop a cooler/heater using a thermoelectric module combined with a parallel flow type oscillating heat pipe with R-142b as a working fluid. The experiment was performed for 16 thermoelectric modules (6A/15V, size: 40×40×4㎜), varying design parameters of the heat pipe (inclination angle, working fluid charging ratio, etc.). Experimental results indicate that the optimum charging ratio and the inclination angle of the parallel flow type oscillating heat pipe were 30% by volume and 30°, respectively. The maximum cooler/heater capacity were 479W (COP : 0.47) and 630W(COP : 0.9), respectively.
