Analysis of characteristics of the structure of plate heat exchanger
Analysis of characteristics of the structure of plate heat exchanger plate heat exchanger due to the special structure of the plate surface, can make the fluid flow in low flow rate under strong turbulent, which greatly strengthen the heat transfer process.
Therefore, heat transfer coefficient of plate heat exchanger is a kind of high adaptability, compact structure, big save material of heat exchanger, easy unpick and wash.
In recent years, water -
Water type plate heat exchanger in urban centralized heat supplying system in our country, has been widely used.
But plate between the narrow flow area, water quality is bad to form scale or dirt deposition, are easy to jam, poor sealing gasket and heat-resistant performance of plate heat exchanger, easy leakage and affect the service life.
