Background

The plate heat exchanger is composed of a press-formed concave-convex stainless steel plate. The concave-convex lines between two adjacent plates are combined oppositely at 180 degrees, so that the concave-convex ridge lines between the two plates of the plate heat exchanger form staggered contact points, and after the contact points are combined in a vacuum welding mode, a high-pressure-resistant staggered circulation structure of the plate heat exchanger is formed, and the staggered circulation structures enable cold and hot fluid in the plate heat exchanger to generate strong turbulence so as to achieve a high heat exchange effect. The plate heat exchanger is composed of a group of corrugated metal plates, and four corner holes are formed in the plates for two kinds of liquid for heat transfer to pass through. The metal plate is installed in a frame with a fixed plate and a movable pressing plate on one side and is clamped by a clamping bolt. The plates are provided with sealing gaskets which seal the fluid passages and guide the fluid to flow into the respective flow passages alternately to form heat exchange. The flow rate, physical properties, pressure drop and temperature difference of the fluid determine the number and size of the plates. Corrugated plates not only increase the degree of turbulence, but also form a number of support points sufficient to withstand the pressure differences between the media. The metal plate and the movable plate pressing plate are suspended on the upper guide rod and are positioned by the lower guide rod, and the rod end is fixed on the support column.
