Structural composition and basic classification of plate heat exchanger
May 30, 2018

The application in modern industrial production is very extensive. It can provide a kind of special equipment for the heat exchange of the equipment medium. The plate heat exchanger is included in it. Due to its structural features, it is relatively prominent, in many devices. All of the above can be used.


In comparison, flat plate heat exchanger is a product with high heat transfer efficiency among various types of heat exchangers. At the same time, it also has the advantages of small space, easy installation and disassembly. The plate heat exchanger consists of a set of stamped and formed corrugated metal plates with four corner holes for the passage of two liquids for heat transfer.


The embossed lines between the two adjacent plates are relatively 180 degrees, so the concave-convex ridges between the plates of the plate heat exchanger form staggered contact points. After the contact points are combined by vacuum welding, they are formed. High pressure resistant staggered flow structures, which create a strong turbulent flow of the hot and cold fluids in the plate heat exchanger to achieve a high heat exchange effect.


For flat plate heat exchangers, fluid flow, physical properties, pressure drop, and temperature difference are all important factors affecting the number and size of plates. The corrugated plate not only increases the degree of turbulence, but also forms a number of bearing points that are sufficient to withstand the pressure difference between the media. The metal plate and the movable plate presser plate are suspended on the upper guide bar and positioned by the lower guide bar, and the bar end is fixed on the support column.


According to the temperature difference and flow of the medium, the plate heat exchanger can be assembled into a single process, a double process, a three process and a multi-process form. A single process refers to a process in which a medium flows through a heat exchanger. A dual process means that a medium is folded back through two processes in a heat exchanger, and so on. When multiple processes are used, the four interfaces of the heat exchanger cannot be on the clamping plate on the same side, and the inlet and outlet are located on the front and rear clamping plates, which can provide users with the need for heat exchange very quickly and effectively. Since the plate heat exchanger has such a significant advantage, it will naturally be recognized by more and more customers, and the scope of application will also expand.
