I believe everyone knows about plate heat exchangers. Do you know which factors are related to pressure reduction when using plate heat exchangers in daily life? Now please follow Wuxi Sushenger Machinery Equipment to learn more.
The pressure drop parameter of plate heat exchangers is very important. If the pressure drop of the medium is too high, it indicates that the pressure of the medium in the subsequent process is insufficient and a pump needs to be purchased for boosting. If the pressure drop is too small, it indicates that the heat exchange area of the heat exchanger is too large and uneconomical.
The pressure drop of plate heat exchangers is determined by the performance of the heat exchanger itself. What parameters determine the pressure drop for a heat exchanger?
Firstly, the number of heat exchangers. The number of parts determines the number of flow channels. The volumetric flow rate of the medium is determined. When the medium enters the heat exchanger, the more channels there are, the slower the flow velocity of the medium in the channels, and the smaller the pressure loss.
The smaller the corner hole of the heat exchanger, the greater the flow rate through the interface, resulting in an increase in pressure drop.
Therefore, the pressure loss of plate heat exchangers is mainly determined by the number of flow channels and the size of the interface, and the number of flow channels is determined by the number of plates. Therefore, when selecting, it is necessary to comprehensively consider the heat transfer capacity and pressure loss, in order to design a reasonable and economical heat exchanger.
