Thermoelectric Intensifier of Heat Transfer between Two Moving Media with Different Temperatures

Abstract

A patented thermoelectric intensifier of heat transfer between two moving media with different temperatures is investigated. Its design envisages the use of fan units in order to increase the heat-transfer intensity between media. A mathematical model of the device is developed based on solution of the heat balance equation for media flows in transport zones under conditions of forward flow. The calculated data are presented in the form of a dependence of the temperature change of moving media along the intensifier for different values of the heat-transfer coefficient between the thermoelectric cell junctions and the air medium in the device gap. It is established that, the larger the temperature difference between the inlet media, the sharper the dependence of the thermopile limit on the heat-transfer coefficient.
