Thermal Circuit Heat Transfer. For heat transfer calculations involving convection conduction and or radiation combined it s convenient to use thermal resistances for each type of heat transfer in calculations. Thermal conduction and thermal convection seldom take place in isolation however.
The resistances are in series and sum to.
A thermal circuit is the representation of the resistance to heat flow in each element of a circuit as though it were an electrical resistor. For heat transfer calculations involving convection conduction and or radiation combined it s convenient to use thermal resistances for each type of heat transfer in calculations. In the composite slab shown infigure 16 6 the heat flux isconstant with. The values of the thermal resistance for the different modes of heat transfer.
