WebTo determine the total heat loss from fin, we use the Fourier’s Law at the base of the fin 0 x fin x T x q Ak (28) Figure 10. Under steady conditions, heat transfer from the exposed surfaces of the fin is equal to heat conduction to the fin at the base. WebAn example is the radiator of a car where the water releases heat to the ambient air and returns to the engine. The two fluids are separated by a conducting medium (usually a metal). A schematic presentation of a counterflow heat exchanger is shown in Figure 5.7. Also shown in Figure 5.7, is an often used symbol for a heat exchanger.
