In general, we mainly according to the structure to distinguish plate heat exchanger, that is, according to the shape to distinguish, can be divided into four categories: ① removable plate heat exchanger (also known as plate heat exchanger with gasket), ② welded plate heat exchanger, ③ spiral plate heat exchanger, ④ plate coil heat exchanger (also known as honeycomb heat exchanger).
Among them, welded plate heat exchanger is divided into: semi-welded plate heat exchanger, fully welded plate heat exchanger, plate and shell heat exchanger, brazing plate heat exchanger.
There are also the following categories that are frequently used:
1 according to the amount of heat transfer area in the unit space, plate heat exchanger belongs to the compact heat exchanger, mainly compared with the tubular and shell heat exchanger, the traditional tubular heat exchanger occupies a large area.
2 According to the use of the process, there are different names: plate heater, plate cooler, plate condenser, plate preheater;
3 According to the process combination, divided into one-wa
