High-Accuracy Brazed Plate Heat Exchanger for Air Dryers

The working principle of plate heat exchangers mainly includes three processes: heat transfer, mass transfer, and resistance. Cold and hot fluids flow through both sides of the plate heat exchanger, with the hot fluid releasing heat on the hot side plate and the cold fluid absorbing heat on the cold side plate, thereby achieving heat transfer. Heat is mainly transferred through convection and conduction. In addition, plate heat exchangers can also achieve mass transfer processes by adding appropriate fillers or membranes to transfer substances between the fluids on both sides.

Plate heat exchangers have a compact and lightweight structure, occupying a small area, only about one-third of that of tube heat exchangers. Plate heat exchangers can adjust the heat exchange area by changing the number of plates, and different baffles can be inserted to change the processing of cold and heat flows and the number of heat exchange sections to meet different process requirements. The heat transfer plate of the plate heat exchanger is processed by stamping, with high standardization, low consumables, and easy maintenance and cleaning.
