Equation (9.5) is valid for any type of heat exchanger. 9.3.1.2 Counterflow Heat Exchanger and the Heat Exchanger Effectiveness In a counterflow or countercurrent heat exchanger, hot and cold fluids enter the exchanger from opposite sides. The counterflow heat exchanger in Fig. 9.5 serves as a ...
The concept of heat exchanger efficiency is extended to the heat exchanger networks. General expressions that can be used for determining the overall efficiency and effectiveness of heat exchangers connected in series regardless of the heat exchanger type have been presented. A simple, accurate, approx...

This paper puts forward an analytical model of heat transfer of a three-fluid separate type heat pipe exchanger. A universal basic temperature transfer matrix equation is obtained from the analysis of heat transfer. The equation is suitable for predicting performance of the parallel- or counter-flow...
In this paper, exergy transfer effectiveness is defined to describe the performance of heat exchangers operating above/below the surrounding temperature with/without finite pressure drop. It is discussed systemically that the effects of heat transfer units number, the ratio of the heat capacity of col...
