Plate heat exchanger is an efficient, compact, and flexible heat exchange device that has been widely used in multiple fields. However, it is also necessary to pay attention to its drawbacks and take corresponding measures to prevent it during use. There are two main types of plate heat exchangers: frame type (detachable) and brazed type. There are three types of plate forms: herringbone corrugated plate, horizontal flat corrugated plate, and nodular plate. These different types of plate heat exchangers have their own characteristics and are suitable for different working conditions and media.

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.

Plate heat exchanger is an efficient heat exchange equipment, mainly composed of a series of metal sheets with specific corrugated shapes stacked together. These metal sheets form thin rectangular channels between them, and heat exchange is carried out through the plates, making it an ideal device for liquid-liquid and liquid vapor heat exchange. Plate heat exchangers have the characteristics of high heat transfer efficiency and low heat loss. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of a tube heat exchanger, and the heat recovery rate can reach over 90%.

Air dryer heat exchangers are widely used in various fields, such as industrial manufacturing, food processing, pharmaceutical and chemical industries, textile printing and dyeing, etc. In these fields, air dryer heat exchangers play a crucial role in ensuring smooth production processes and stable product quality.
