摘要：

The processes of heat transfer in air and liquid plate-fin heat exchangers of a thermoelectric cooling system are considered. The flow modes in interfin channels are analyzed, and the local heat-transfer coefficients are determined. From the numerical solution of the two-dimensional heat-conduction problem, dependences of the thermal resistances of heat exchangers on their geometric parameters are obtained. The influence of thermal resistances on the cooling capacity and on the coefficient of performance of the thermoelectric cooling system is determined. Optimization of heat exchangers in terms of fin thickness and interfin spacing has been performed.
