The calibration and plate type of the heat exchanger should be low-resistance plate type, and the plate or corrugated type should be determined according to the actual needs of the heat exchanger. Large flow and small pressure drop. Instead, choose the type of board with high resistance. Based on the fluid pressure and temperature, it was determined that the removable type was still brazed. When determining the type of heat exchanger plate, it is not appropriate to choose a plate with a small plate area to avoid too many plates, the flow velocity between the heat exchanger plates is too small, and the heat transfer coefficient is too low. This should focus more on larger heat exchangers. There are certain requirements for drops, and the design of the heat exchanger is selected. Therefore, it should be checked. If it is checked that the heat exchanger pressure drop exceeds the allowable pressure drop, the design selection calculation must be repeated until the process requirements are met.
