Plate heat ex-changer is made of many corrugated sheets at a certain interval, sealed by gaskets on all sides, and the plates and gaskets of the heat ex-changer are pressed and overlapped by a frame. The four corner holes of the plates and gaskets form the distribution pipes and collection pipes of the fluid, and at the same time, the cold and hot fluids are reasonably separated, so that they flow in the flow channels on both sides of each plate, and heat exchange is carried out through the plates.
Main categories:
1. Removable plate heat ex-changer (TGS, LTG series)
2. Standard brazed plate heat ex-changer (TGL series)
3. Removable fully welded plate heat ex-changer (QY series)
4. Circular shell and tube heat ex-changer (QYS series)
5. Bacchus plate Evaporator, Condenser (TGE, TGE series)
Advantages and disadvantages of plate heat ex-changer:
1. Compact structure, large heat exchange area per unit volume.
2. Strong adaptability, the required heat exchange area can be met by adding or reducing plates.
3. Small heat loss.
4. Due to the small plate gap (2-8mm), the material can pass through quickly and thinly, and the heat exchange temperature can be accurately controlled.
Disadvantages:
1. Due to the limitation of the structural form, a rubber sealing gasket must be used, and the sealing perimeter is long and difficult to seal.
2. The pressure bearing capacity is low (not higher than 2Mpa), and the operating temperature (not higher than 180℃) is limited by the temperature re
