Heat exchangers play an important role in power, the chemical industry, petroleum, food and many other industrial productions, while compact heat exchangers are more favored in industrial applications due to their high thermal efficiency and small size. This paper summarizes the research status of different types of compact heat exchangers, especially the research results of heat transfer and pressure drop of printed circuit heat exchangers, so that researchers can have an overall understanding of the development of compact heat exchangers and get the required information quickly. In addition, this paper summarizes and analyzes several main working fluids selected in compact heat exchangers, and puts forward some discussions and suggestions on the selection of working fluids. Finally, according to the existing published literature, the performance evaluation indexes of compact heat exchangers are summarized and compared, which is convenient for developers and researchers to better grasp the design direction.

Irreversible Effects

A mathematical model is described which permits the performance analysis of advanced Brayton cycles as used in turbine engines for stationary and flight power plant applications. The model permits the performance evaluation of different working fluids, provides for various component combinations, and facilitates exchange of parameters and variables for off-design point performance and tradeoff studies. The concept of entropy production is used for expressing the losses (irreversible effects, efficiencies) occurring in components of turbine engines. The derived equations permit the use of specific heat as a function of temperature in energy, entropy, and mass flow relations and establish a consistent set which facilitates the generalized performance analysis. Examples related to open and closed Brayton cycles are discussed. Two significant relationships are obtained for the evaluation of working fluids.
