Plate Heat Exchanger Structure
The plate heat exchanger is mainly composed of two parts: a frame and a plate. Plates made of various materials are pressed into corrugations of various shapes by various types of abrasive tools, and angular holes are formed in the four corners of the plate for the flow path of the medium. The periphery of the plate and the corner hole are sealed with a rubber gasket. The frame is composed of a fixed pressing plate, a movable pressing plate, upper and lower guide bars, and clamping bolts. The plate heat exchanger is formed by superimposing the plates in the middle of the fixed pressing plate and the movable pressing plate, and then clamping them with clamping bolts.
By reducing the thermal resistance of the plate heat exchanger, the heat transfer efficiency can be improved. This is one of the directions we have been working hard, but how to reduce the thermal resistance and reduce the thermal resistance of the plate heat exchanger is an urgent problem to be solved. I have also done a lot of common sense and research on this subject, and finally concluded that changing the structure of the plate heat exchanger is an effective way to reduce the thermal resistance.
When we adjust the structure of the plate heat exchanger, as long as we can increase the flow velocity of the fluid between the plates, we can increase our heat transfer coefficient and reduce the heat exchange area. But the point is that if we increase the flow rate of the plate heat exchanger, it will also increase the resistance of the plate heat exchanger.
