Experimental performances of a thermoelectric cooler box with thermoelectric position variations

Abstract

An experimental performance investigation on thermoelectric cooler box with several positions of the thermoelectric was performed. The cooling system of the cooler box comprised a thermoelectric module model TEC1-12706, a heatsink-fan, an inner heat sink, a bottle of water with a volume of 360 ml. The positions of the thermoelectric were at the top, on the bottom, and on the wall. The inner cooler box size employed was 215 mm × 175 mm × 130 mm, and the thickness of the cooler box walls was 50 mm. The experiment was conducted for about 18,000 s at the open ambient temperature. The power used was constant of about 38.08 W. The results showed that the COP decreased with the times, and the best position of the thermoelectric placement of this study was on the wall.
