Study of cooling performance with channel configuration

A thermoelectric generator (TEG) is a solid-state device that converts thermal energy directly into electrical energy. They have no moving parts inside, so they have a long operating life, are noiseless, and can operate reliably. They are also environmentally friendly, as they are pollution-free. Thermoelectric generators have great potential for harvesting ambient energy. this study aims to design a cooling system that attaches to the cold side of the thermoelectric modules. Three cases are considered based on the coolant inlet and outlet locations and flow path geometry. The average temperature of cooling system surface, temperature unifomlity, and pressure drop between the coolant inlet and outlet are selected as the performance indicators of the cooling system. Type 1-1, which had the lowest pressure drop between inlet and outlet, but the highest average cooling surface temperature and temperature uniformity, was judged to be the best performing case.
