Design and Study of the Thermoelectric Performance of Mini Cooler Box Using TEC

The need for cooling is increasing worldwide and to reduce global warming vapour compressor pump usage should be replaced. The advent of thermoelectric cooling showed an opportunity for alternate small level cooling that is portable, has no mechanical parts, and is easily current controlled. But the efficiency level found so far is not a match for the conventional present day existing technology using vapour compressor refrigeration. This paper attempts to build a mini cooler box of volume 3.5 litres using one TEC1-12706, 2 heat sinks with DC fans on both hot and cold sides, and a circulating water with a DC pump, and analyse its various parameters found during the experiment. The COP found is 0.7. Also, some conclusions for even results have been suggested.
