Plate Heat Exchanger Service
The PHE uses robust stainless steel plates as the primary medium for heat transfer.Alternate materials such as SMO254,a corrosion resitant steel alloy, and Titanium are avalable on request.Each plate is stamped with an optimised coccugated design.The exchanger plates create alternating independent channels for both the process and service fluid.The two medium circuits are configured to induce true counter-current flow,enabling the heat exchanger to perform at extremely low temperature approaches.
According to its function, a piece of plate can be divided into five parts:the flow guiding part, the heat exchange part, the sealing part, the edge support, and the suspension positioning. the heat transfer part is the core of the plate structure. The structure of the heat transfer part mainly depends on the nature of the heat transfer medium, which is determined according to heat transfer theory and fluid mechanics design.
In the plate heat exchanger design, the overall structure of the plate is closely related to the sealing strength. A reasonable design of the sealing structure not only improve the rigidity of the plate, but also improve the pressure resistance of the plate cooler and ensure good Sealing. The sealing structure consists of the sealing groove and sealing gasket of the plate. The performance (physical, chemical and process properties) of the sealing gasket, the form of the sealing groove, and the compression ratio of the sealing gasket are the three major elements of the sealing design.
