Experimental performance of a cooler box with heat dissipation unit variations

Abstract

An experimental investigation on the thermoelectric cooler box with several heat dissipation units was conducted in the unconditioned environment. The cooler box cooling system in this study comprised a TEC2-25408 thermoelectric module, an inner heat sink, four bottles filled with water, and heat dissipation units. The heat dissipation unites employed were a heat sink with a fan, a heat sink without a fan, a heat pipe with a fan, and a heat pipe without a fan. The cooler box dimension was 0.397 m x 0.305 m x 0.25 m. The powers supplied to the thermoelectric ranged from 27.65 W to 36.51 W. The experiment was performed for 1800 seconds, and the data were recorded using the NI DAQ MX 9714 connected to the PC. The ambient temperatures were detected from 26.6°C to 30.82°C. The results showed that the cooler box using a heat sink with a fan demonstrated the lowest cooler box temperature (23°C), and the highest COP (0.044), while the cooler box utilizing three other dissipation units exhibited opposite.
