STUDY ON INFLUENCE OF STRUCTURAL PARAMETERS UPON PERFORMANCE OF MULTI-STREAM PLATE-FIN HEAT EXCHANGERS

摘要

In this paper, the energy equations about the parallel multi-stream plate-fin heat exchangers are deduced, and the numerical calculations are performed. Under the conditions of considering the fin bypass and ignoring it, by changing the structural parameters of multi-stream plate-fin heat exchangers, such as fin height, fin thickness, and so on, the effects of the structural parameters on the performance of heat-transfer and friction performance of multi-stream plate-fin heat exchangers are obtained.
