Abstract

Thermoelectric refrigeration achieves cooling through Peltier and Seebeck effect. Heat sinks attached to the hot and cold sides of the thermoelectric module help to efficiently dissipates and absorb heat. This research modelled the temperature profile across a heat sink and its optimization for a thermoelectric refrigeration application. Simulation was carried out using MATLAB to visualize the performance of the heat sink. The optimization was done using FMINCON in MATLAB by setting upper and lower bounds to satisfy space and volume requirement.  The optimum values for the hot and cold heat sink geometry obtained using FMINCON tool in OPTIMTOOL box in MATLAB, yields number of fins as 10, fin spacing as 0.003m, the fin thickness as 0.002m and fin length as 0.015m with an optimum temperature of -0.8639.
