Summary:Peltier cooling systems utilizing liquid heat transfer directly with thermoelectric modules are adopted in fridges for hotel-use, home-bar and so forth. This paper reports the development of a highly efficient, high capacity liquid heat exchanger in which a thermoelectric module is installed to minimize electric power consumption and reduce cost. In the heat exchanger, a highly efficient 62-mm diameter round thermoelectric module is used and liquid heat transfer on the surface of the thermoelectric module is enhanced using impeller rotation for liquid pumping. The cooling system utilizing the heat exchanger combined with pump achieves equal cooling capacity with a COP of 2.1 times in comparison with the cooling system for the current manifolds with three 40/spl times/40 mm thermoelectric modules.
