The heat exchanger machine is an energy-saving equipment that realizes heat transfer between materials between two or more fluids at different temperatures. It transfers heat from a higher fluid to a lower temperature fluid, so that the fluid temperature reaches the process The specified index is one of the main equipment to meet the needs of the process conditions and also improve the energy efficiency. Among them, the plate heat exchanger is one of the more rapidly developed heat exchangers in recent years.
It is understood that the plate heat exchanger machine is a new type of high-efficiency heat exchanger formed by stacking a series of metal sheets with a certain corrugated shape. Its working principle is to form thin rectangular channels between various plates, through which heat exchange is carried out. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange.
According to different structures, plate heat exchangers can be divided into detachable plate heat exchangers, welded plate heat exchangers, spiral plate heat exchangers, and plate coil heat exchangers. Among them, welded plate heat exchangers are divided into semi-welded plate heat exchangers, fully welded plate heat exchangers, plate and shell heat exchangers, and brazed plate heat exchangers.
Compared with traditional heat exchangers, plate heat exchangers have the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, easy installation and cleaning, wide application, and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, covering an area of one third of that of the tubular heat exchanger, and the heat recovery rate can be as high as 90% or more.
