Plate heat exchanger efficiency affects our work efficiency, improving the work efficiency has become an important work. Propellent provide four action methods to improve the efficiency as below.

　　1、To improve the plate surface heat transfer coefficient

　　Because the corrugated can make the fluid in smaller under turbulent flow velocity, and therefore can obtain higher surface heat transfer coefficient, surface heat transfer coefficient and the geometrical structure of the plate of corrugated and the flow of the medium. The waveform including chevron, flat plate, the ball, etc.

　　2、Reduce the thermal resistance of dirt layer.

　　Reduce fouling layer thermal resistance of heat exchanger is the key to prevent the plate scale. Plate scale thickness to 1 mm, decrease the heat transfer coefficient by 10%. On either side of the cold and hot water, therefore, must pay attention to monitoring heat exchanger, prevent plate scale, and to prevent the water impurities attached on the plate.

　　3、With high thermal conductivity of plates

　　Plate material is available in austenitic stainless steel, titanium alloy, copper alloy, etc. Stainless steel heat conduction performance is good, thermal conductivity is about 14.4 W/(m K), high intensity, stamping performance is good, not easy to be oxidized, low cost of titanium alloy and copper alloy, most used in heating engineering, but its resistance to chlorine ion corrosion ability is poor.

　　4、Reduce plate thickness.

　  The design of the slab thickness and corrosion resistance, associated with the bearing capacity of the heat exchanger. Plate thickening, can improve the bearing capacity of the heat exchanger. Using chevron plate combination, adjacent plate upside down to each other, corrugated contact each other, to form the high density, homogeneous distribution of fulcrum, plate angle away L and edge sealing structure has been gradually improved, make the plate heat exchanger has the very good bearing capacity.
