Plate Heat Exchanger Heat Transfer Coefficient High Texture Surface Plate Introduction


Plate heat exchanger heat transfer coefficient of high-quality surface plate there are three main. Protruding plate, fence plate and the font plate, in the field of heating the most used. In the low flow rate that is 0.15 ~ 0.85m / s can stimulate the turbulent flow state, and the heat transfer coefficient on both sides of the plate is very high, according to the information, plate heat exchanger in the Reynolds number greater than 50 to 200, Thermal coefficient of water for a water heat transfer of 15000 ~ 21000K / ㎡.h · ℃, two tube only 3200 ~ 6300K / mh · ℃, the data show that the plate heat exchanger heat transfer coefficient is tube 2 ~ 4 times, while the pressure drop near the fish near.
