As a kind of equipment widely used in chemical, oil refining, power, food, light industry, atomic energy, pharmaceutical, machinery and other industries, plate heat exchangers are highly valued, and the manufacturing process is further mechanized and automated. Various new technologies will play an important role in heat exchangers. Because of its high reliability, simple structure, compact structure, high pressure, low cost and wide application range, it has been challenged by other new heat exchangers, but it has promoted its own development. Since the equivalent diameter of the flow between the plates is small, the plate-shaped corrugation makes the cross-section change complicated, the disturbance of the gas flow is intensified, the turbulence can be achieved at a lower flow rate and high efficiency.The treatment can be used from water to high viscosity. Heating, cooling, condensation, evaporation.
The fluid flow pattern in the platesis divided into a diagonal flow and a unilateral flow. At present, Most mainstream brands of plate heat exchangers adopt single-sided flow, and the advantages of single-sided flow relative to diagonal flow are: few spare parts; easy to install and maintain..
