Issues related to plate heat exchangers

This post was last edited by sunjl1981 on 2013-1-7 00:26 for advice: What is the relationship between the cooling water flow rate in the plate heat exchanger, and what are the specific effects of being too fast or too slow? In addition, does the size of the flow rate have any impact on the corrosion of the plate heat exchanger? # hcbbs
What does the flow rate in the heat exchanger you mentioned relate to? I think it refers to the flow rate between plates. It is related to cooling water pressure, corrugation angle and number of flow channels. In a heat exchanger with too fast flow rate between plates, the resistance of the heat exchanger will be greatly reduced. If it is too slow, the flow rate at the rear end of the heat exchanger will be small and scale will easily form. Therefore, the inter-plate flow rate of the heat exchanger needs to be designed with different heat exchanger parameters based on specific process conditions. Flow rate has little bearing on the corrosiveness of the heat exchanger. This post was last edited by limingshuguang on 2009-4-19 09:52 ]
I completely agree with Lou Zhu's statement that the flow rate between the panels is related to the cooling water supply and return water pressure, the corrugation angle and the number of flow channels. The heat exchanger leaves the factory. During operation, the flow rate between the plates is mainly affected by the cooling water supply and return water pressure. When circulating water is used as the cooling medium, the rate of scaling at the rear end of the heat exchanger will be accelerated if the flow rate is small. The scale layer is also corrosive to a certain extent! This post was last edited by limingshuguang on 2009-4-19 09:53 ]
