An Experimental Study on the Effects of the Cooling Jacket Design Parameters on the Performance of Thermoelectric Cooling System

열전소자 냉각 자켓의 설계인자가 열전냉각 시스템의 성능에 미치는 효과에 대한 실험적 연구

A small-scale thermoelectric cooling system was built in an effort to enhance the performance of the refrigeration system by utilizing the water-cooled jacket which was attached on the hot side of the thermoelectric module. Considered design parameters for the water-cooled jacket included the geometry of the flow passage inside the jacket and the flow rate of cooling water. The higher flow rate of cooling water in the jacket resulted in a better performance of the refrigeration system. The introduction of geometrical complexity of the cooling water flow passage to the cooling jacket also showed significant improvement on the performance of the thermoelectric refrigeration system such as the cooling capacity and the COP of the refrigeration system.
