Experimental Performance of a Peltier Cooler Box Employing Water Block Heatsink

This paper presents the experimental performance of a Peltier cooler box using a water block heatsink. A prototype of the cooler box has been built and tested. The experimentation uses a TEC-12706 thermoelectric module for obtaining the cooling effect. Water as a coolant flows through the mini channels of the copper heatsink block at a constant volume flow rate of 2.5 L/min. A fin-type heatsink is attached to the cold side of the Peltier module. The cooler box draws constant DC voltage at 12 V from the power supply unit. A water volume of 1.5 L is employed for the heat load test. The test results show that the water load reaches the lowest temperature at 11.18 °C within 130 min resulting in the COP system of 0.203. The effect of the voltage difference on the system performances needs to be investigated for the solar power-driven Peltier cooler box experimentation.
