The plate heat exchanger is a new type of high-efficiency heat exchanger which is assembled from a series of metal sheets with a certain corrugated shape. A thin rectangular channel is formed between the various sheets, and heat is communicated through the metal sheets. The plate heat exchanger is a device for heat communication between liquid-liquid and liquid-vapor. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, convenient equipment cleaning, wide application and long service life.
The plate heat exchanger is mainly composed of a heat transfer plate, a sealing gasket, a pressure plate at both ends, a clamping bolt, a support.
(1)The heat transfer plate:The heat transfer plate is the first heat exchange element of the heat exchanger. Usually, the corrugation is made in a herringbone shape. According to the different fluid medium, the heat transfer plate is different in material, and most of them are made of stainless steel and titanium.
(2Heat exchanger gasket:The gasket of the plate heat exchanger is primarily a sealing function between the heat exchange plates. Its material includes: nitrile rubber, EPDM rubber, fluorine rubber etc.It use different rubber according to different media.
(3) The two ends of the pressure plate:The pressure plates at both ends are primarily clamped against a total number of heat transfer plates to ensure that the fluid medium does not leak.
(4) The clamping bolt:The clamping bolts are primarily used to tighten the pressure plates at both ends. The clamping bolts are usually double-ended threads. When the bolts are pre-tensioned, the torque of the fixing plates is even.
(5)Rack:The first is to support the heat exchange plate to make it easy to disassemble, clean and assemble.
