Термоэлектрический Интенсификатор Теплопередачи Между Двумя Движущимися Средами С Различной Температурой

Abstract

The patented thermoelectric intensifier of heat transfer between two moving media with different temperatures was investigated. In its design, to increase the intensity of heat exchange between media, the use of fan units is provided. A mathematical model of the device was developed, based on the solution of the heat balance equation for media flows in transport zones for forward flow conditions. The calculated data are presented in the form of the dependence of the temperature change of moving media along the length of the intensifier for different values ​​of the heat transfer coefficient between the junctions of the thermoelectric battery and the air medium in the gap of the device. It has been established that the larger the temperature difference between the inlet media, the more abrupt the dependence of the limiting length of the thermoelectric battery on the heat transfer coefficient will be.
