What is pressure drop in heat exchanger

What is pressure drop in heat exchanger?

   Any kinds of the heat exchanger in the process of heat transfer. The medium will have a certain resistance when flowing through the heat exchanger, the medium outlet pressure is lower than the original inlet pressure, and the pressure difference between the inlet and outlet media is It is the pressure drop of the heat exchanger. In order to enhance the heat transfer, we will set some spoiler elements in the flow channel to increase the degree of turbulence and enhance the heat transfer, so the pressure drop will be greater during the strengthening process. The power required is even bigger, so the pressure drop must not be made too large. In order to consider cost and benefit and energy loss, an allowable pressure drop is proposed to limit the pressure drop to a certain range.
