The plate heat exchanger is a detachable heat exchange device composed of many corrugated heat transfer plates, which are pressed at a certain interval through a rubber gasket. When the plates are assembled, they are alternately alternated, and the rubber sealing strips are fixed by joints between the plates, and their function is to prevent the fluid from leaking into the two plates to form an elongated net-shaped flow channel, and the heat exchange plates are pressed into each A corrugated shape to increase the area and rigidity of the heat exchange plate, and can make the fluid into a vortex at a low refractive index to low to achieve the effect of enhancing heat transfer. The four corner holes of the panel form a fluid distribution tube and a drain header. The two heat exchange media are placed in their respective flow channels to form counterflow or cocurrent flow through each plate for conversion exchange.
(1) Small volume and small volume;
(2) High heat transfer efficiency;
(3) Flexible assembly;
(4) Low metal consumption;
(5) Small heat loss;
(6) Disassembly, cleaning and maintenance are convenient;
(7) The defect of the plate heat exchanger is that the periphery of the seal is extended and it is easy to leak.
The use temperature can only be lower than 150oC, the pressure difference is reduced, the processing capacity is small, and the plate must be disassembled and cleaned once it is found.
