(1) High heat transfer capacity, K value of heat transfer coefficient is in the range of 3000 ~ 8000 W / (m · K), which is higher than other heat exchanger types.
(2) The plate heat exchanger has a high heat transfer coefficient, which determines its compact structure and small size. It can arrange a heat transfer area of 250 square meters per cubic meter volume, which is much better than other types of heat transfer. Device.
(3) The plate heat exchanger also has the characteristics of flexible assembly, convenient disassembly and cleaning, and the heat exchange area can be changed by increasing or decreasing the number of plates to adapt to the change of heat load. In the same heat exchanger, for relatively pure fluids, you can also increase the flow rate between plates by increasing the number of processes to achieve a high heat transfer coefficient.
⑷ Because two seals are used between the cold and hot media of the plate heat exchanger, and holes are opened between the two seals to communicate with the atmosphere, the two media can be effectively avoided.
