Plate heat exchanger is a kind of heat exchange equipment widely used in modern industry and civil use. It has been widely used in heating, refrigeration, chemical, food, machinery and other industries.

    The size of the pressure drop parameter of the plate heat exchanger is very important. If the medium pressure drop is too large, the medium pressure in the subsequent process is insufficient, and a pump needs to be purchased for pressurization. If the pressure drop is too small, it means that the heat exchange area of the heat exchanger is too much, which is not economical.

    In practical applications, what are the factors that affect the pressure drop of the plate heat exchanger?

    The pressure drop of the plate heat exchanger is determined by the performance of the heat exchanger itself. The following Propellent briefly introduces the factors that affect the pressure drop of the heat exchanger:

    (1) The plates number of the plate heat exchanger: the number of plates determines the number of runners. The volume flow rate of the medium is constant. When the medium is passed into the heat exchanger, the more the number of flow channels, the slower the flow rate of the medium in the flow channel, and the smaller the pressure loss.

    (2) The size of the heat exchanger interface: the smaller the corner hole of the heat exchanger, the higher the flow rate through the interface, which will increase the pressure drop.

    (3) Heat exchanger blockage: When the heat exchange equipment is blocked, the pressure drop will change significantly.

    The pressure drop of the plate heat exchanger is mainly determined by the number of plates, the size of the interface and whether it is blocked. Therefore, when the heat exchanger is calculated, it is necessary to comprehensively consider the heat exchange capacity and pressure loss, so that a reasonable and economical heat exchanger can be designed.
