Plate heat exchanger is a new type of efficient heat exchanger which is composed of a series of metal plates with a certain corrugated shape.In general, we mainly distinguish the plate heat exchanger according to its structure, that is, according to its appearance, which can be divided into four categories.
(1) Removable plate heat exchanger:Removable plate heat exchangers have many heat exchanger plates arranged at intervals, sealed by sealing gaskets around them and pressed by clamping bolts. The holes at the corner of the plate form a continuous passage. The medium enters the passage from the entrance and is distributed into the passage between the heat exchanger plates.
(2) Welded plate heat exchanger.And welded plate heat exchanger is divided into: half welded plate heat exchanger, all welded plate heat exchanger, plate and shell heat exchanger, brazed plate heat exchanger
(3) Spiral plate heat exchanger
(4) Plate heat exchanger with coil type
