| Abstract: | By deducing the logarithmic mean temperature of counter flow plate heat exchanger, the temperature distribution of plates and flows is analyzed. Additionally, the local coefficient of exergy transfer is deduced, which is related to heat flow to plate and plate to cold flow. A case of plate heat exchangers is presented, and the heat transfer performance of the case is analyzed from the aspect of exergy transfer, and the conclusion can be used as a significant reference to optimize the plate heat exchanger. |
