When we use plate heat exchanger products, how to improve the efficiency of plate heat exchanger? Here are four ways to improve your productivity.
Improve the surface heat transfer coefficient of the plate
Because the ripple can make the fluid turbulent at a small flow rate (Reynolds number 1 150), a high surface heat transfer coefficient can be obtained, and the surface heat transfer coefficient is related to the geometry of the plate ripple and the flow state of the medium. The waveforms of the plate include herringbone, flat shape, spherical shape, etc.
Select plates with high thermal conductivity
Plate material can choose austenitic stainless steel, titanium alloy, copper alloy, etc. Stainless steel has good thermal conductivity, thermal conductivity of about 14.4W /(m·K), high strength, good stamping performance, not easy to be oxidized, lower price than titanium alloy and copper alloy, more used in heating engineering, but its resistance to ammonia ion corrosion is poor.
Reduce thickness of plate heat exchanger plates
The design thickness of the plate has nothing to do with its corrosion resistance and is related to the pressure bearing capacity of the heat exchanger. Plate thickening can improve the pressure bearing capacity of heat exchanger. When the herringbone plate combination is used, the adjacent plates are inverted and the ripples contact each other.
Reduce the thermal resistance of dirt layer
The key to reduce the thermal resistance of fouling layer of heat exchanger is to prevent sheet scaling. When the scale thickness of the plate is 1mm, the heat transfer coefficient is reduced by about 10%. Therefore, it is necessary to pay attention to monitoring the water quality on both sides of the heat exchanger, prevent the plate from scaling, and prevent the debris in the water from adhering to the plate.
