Product Details

  The heat transfer coefficient of plate heat exchanger is an index to measure the heat transfer performance. The heat transfer coefficient of different heat exchangers is different in the same fluid treatment and temperature treatment process.Increasing the heat transfer coefficient of the heat exchanger can reduce the thermal resistance of the fouling layer and select a plate with high thermal conductivity.

  The key to reducing the thermal resistance of the fouling layer of the heat exchanger is to prevent plate fouling.When the sheet scale is 1 mm thick, 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 to prevent scaling of the plates and prevent the inclusion of impurities in the water on the plates.Some heating units add chemicals to the heating medium to prevent water theft and corrosion of steel. Therefore, it is necessary to pay attention to the heat exchanger plates caused by water and viscous agents.If there is sticky debris in the water, use a special filter for disposal. When using a drug, it is advisable to choose a non-stick agent.

  The material of the plate can be selected from austenitic stainless steel, titanium alloy, copper alloy etc.Stainless steel has good thermal conductivity( 14.4W /m.K), high strength, good stamping performance.it is not easy to be oxidized, the price is lower than titanium alloy and copper alloy.It’s widely used in heating engineering, but its resistance chlorine ion corrosion is poor.
