The plate heat exchanger consists of a set of corrugated metal plates, and the holes in the plates are used for the two liquids for heat transfer. The metal plate is installed in a frame with a fixed plate and a movable compression plate, which is clamped with a clamping bolt.he sealing gasket on the plate seals the liquid channels and directs the fluid to alternately flow into the respective channels.Customers are concerned about the heat transfer efficiency of the plate heat exchanger, which directly affects the actual use. Is there any way to improve the heat transfer efficiency of the plate heat exchanger?
(1) Use a plate with high thermal conductivity. The material of the plate can be selected from stainless steel, titanium alloy and copper alloy
(2) Increase the surface heat transfer coefficient of the plate. Due to the corrugation of the plates of the heat exchange equipment, the fluid can produce a ray at a lower flow rate. Therefore, a higher surface heat transfer coefficient can be obtained, which is related to the geometry of the plate corrugations and the flow state of the medium.
(3) Reduce the thickness of the plate. The design thickness of the plate has nothing to do with its corrosion resistance and is related to the pressure capacity of the heat exchanger. The thicker plate can improve the pressure capacity of the plate heat exchanger;
(4) Reduce the thermal resistance of the dirt layer. The key to reducing the thermal resistance of the dirt layer of the plate heat exchanger is to prevent plate fouling.
