The plate heat exchanger is made of many heat exchange plates (metal sheets punched with corrugated grooves), which are sealed by sealing gaskets around a certain interval, and pressed with clamping studs. The holes on the corners form a continuous channel. , the medium enters the channel from the inlet and is distributed into the flow channel between the heat exchange plates, each plate has a sealing gasket, the positions between the plates are alternately placed, and the two fluids enter their respective channels. , separated by plates. Generally, the two media flow countercurrently in the channel. The heat medium transfers the heat energy to the plate, and the plate transfers the heat energy to the cold medium on the other side, so that the temperature of the heat medium can be reduced by Cooling, the temperature of the cold medium is raised to obtain the purpose of heating.
The main features of plate heat exchanger are: high heat transfer coefficient; easy maintenance and cleaning (when THE comes out, this is relatively reduced); low fouling coefficient; compact structure, small footprint and light weight; it is easy to change the heat exchange area or process combination; small temperature difference at the end, etc.
However, compared with the semi-welded plate heat exchanger (SWPHE), the fully welded plate heat exchanger (WPHE) and the brazed heat exchanger (CBE), the detachable heat exchanger has lower temperature and pressure bearing capacity. , poor corrosion resistance.
