HOW TO OPTIMIZE YOUR PLATE HEAT EXCHANGER DESIGN
1.1 Improve heat transfer efficiency The cold and hot fluids transfer heat through the plates of the heat exchanger. The plate heat exchanger is an inter-wall heat transfer heat exchanger. The fluid is in direct contact with the plate, and the heat transfer methods are heat conduction and convection heat transfer. The key to improving the heat transfer efficiency of the plate heat exchanger is to increase the heat transfer coefficient and the logarithmic average temperature difference. A Reduce the thermal resistance of the dirt layer: ① Improve the heat transfer coefficient of the heat exchanger Only at the same time increase the external heat transfer coefficient of the cold and hot plates. Only use plates with high thermal conductivity to reduce the thickness of the plates to effectively increase the heat transfer coefficient of the heat exchanger. a. Improve the heat transfer coefficient of the plate The external heat transfer coefficient is related to the geometric structure ...
