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.

The heat exchanger in an air dryer is an important component that mainly condenses the moisture in humid air into liquid water through heat exchange, and then removes the water through discharge or evaporation to achieve the purpose of drying the air. The following is a detailed analysis of the air dryer heat exchanger:
