An investigation on heat transfer performance of a new type of plate heat exchanger with dimples

摘要

A new type of plate heat exchanger, consisting of plates with dimples, is designed and studied. Experimental results nad numerical simulations for the performance of fluid flow and heat transfer in such compact heat exchanger are reported. These results ar analysed and also ocmpared with conventional PHEs. THe advantages of this new type of heat exchanger, such as the performance of turbulent flow and the enhancement of heat transfer, as well as the potential of reducing fouling, are discussed in the paper.
