Due to the special effect of the corrugated surface of the plate, the fluid in the heat exchanger flows along a narrow and curved channel, causing a change in its velocity and resulting in a strong increase in the fluid flow velocity (Rc=200). This accelerates the destruction of the fluid boundary layer and enhances the heat transfer efficiency, improving the heat transfer capacity and making it compact in structure, low in metal consumption, easy to operate, heat loss, installation, inspection and cleaning, strong corrosion resistance, and service life

The heat exchanger process consists of assembling and assembling plates A and B according to the specified process and technical requirements. The plates are alternately arranged in a mesh like channel with four corner holes, and the pipes are combined with sealing gaskets for cold and hot media. The heat exchanger is mixed with reasonable cold and hot media on the channel surface, and the cold and hot fluids flow in a counter current and downstream flow. The cold and hot fluids pass through the plate wall for heat exchange. The plate heat exchanger process combination form adopts the same reversing plate and assembly to achieve the process combination form. The single process flow is vapor-liquid exchange process, and the mixed process form
