In the case of low medium pressure, we can also improve the heat transfer efficiency by changing the plate thickness and other methods to reduce the number of plates. At the same time, more reasonable plate structure and plate type can be selected to effectively reduce the heat transfer area.
In the process of selecting and purchasing plate heat exchangers, the heat exchange area of the plate heat exchanger is determined by the plate type and plate number of the plate heat exchanger, which directly affects the price of the plate heat exchanger and the purchase cost of the plate heat exchanger. It is our common goal to pursue higher economic benefits, less money and buy good things. However, when selecting plate heat exchangers, we cannot blindly reduce the heat exchange area. How can we reduce the heat exchange area within a reasonable range? Let it not affect the use of plate heat exchanger?
First of all, the multi-process plate heat exchanger structure can be adopted, and the multi-process plate heat exchanger can significantly reduce the heat exchange area of the plate heat exchanger under certain conditions, so as to achieve its heat exchange purpose. However, our actual working conditions should be analyzed according to specific problems, not be generalized.
Secondly, in the case of excessive heat exchanger, the pressure loss permit of plate heat exchanger can be expanded, the number of tablets can be reduced, the heat exchange area can be increased, and the pressure drop can be increased. It also needs to be analyzed according to the actual operation.
In the case of low medium pressure, we can also improve the heat transfer efficiency by changing the plate thickness and other methods to reduce the number of plates. At the same time, more reasonable plate structure and plate type can be selected to effectively reduce the heat transfer area.
The above is what factors should be paid attention to when selecting less plate heat exchanger heat exchange area. I hope it will help you!
