Reduce the thickness of the plate The design thickness of the plate has nothing to do with its corrosion resistance, but is related to the pressure bearing capacity of the heat exchanger. Because the corrugation of the plate heat exchanger can cause the fluid to produce turbulence at a small flow rate (Reynolds number-150), it can obtain a Heat Exchangers FHC052G Exporters higher surface heat transfer coefficient.2
Ways to reduce the resistance of the heat exchanger Increase the average flow velocity of the medium in the inter-plate runner, which can increase the heat transfer coefficient and reduce the area of the heat exchanger. On the premise of meeting the pressure bearing capacity of the heat exchanger, the thickness of the plate should be as small as possible.1 Improve heat transfer efficiency. 2.
Therefore, care must be taken to monitor the water quality on both sides of the heat exchanger to prevent fouling of the plates and prevent debris in the water from adhering to the plates. After years of research and experimentation, it has been found that the corrugated cross-sectional shape is triangular (sine-shaped surface heat transfer coefficient is the largest, the pressure drop is small, the stress distribution is uniform under pressure, but the processing is difficult?) Herringbone plates have higher surface transmission Thermal coefficient, and the greater the angle of the corrugation, the higher the flow velocity of the medium in the flow channel between the plates, and the greater the surface heat transfer coefficient.
④ Set heat exchanger bypass pipe When the flow of cold and heat medium is relatively large, a bypass pipe can be installed between the inlet and outlet of the heat exchanger on the large flow side to reduce the flow into the heat exchanger and reduce resistance. Improve the surface heat transfer coefficient of the plate. The maximum pressure capacity of the domestic detachable plate heat exchanger has reached 2. It is not economical to increase the flow rate to obtain a slightly higher heat transfer coefficient. ⑤ Selection of the form of the plate heat exchanger
