Calculation of heat transfer from a continuous fin of a heat exchanger under conditions of unequal temperatures of gas flows and the base of the ribs

The solution of the problem of heat flux from a fin surface washed by gaseous media with different temperatures at asymmetric temperatures of the solid rib bases and unequal values of the heat transfer coefficients is obtained. The solution of the problem of heat transfer through a flat rib of constant cross section at different temperatures of the end sources, unequal media temperatures and different heat transfer coefficients on the surfaces of the rib is presented. The calculated dependencies can be used for designing heat-exchange devices in power plants, agricultural technological equipment systems, air conditioning, ventilation and heat supply systems.
