Plate heat exchanger is a new type of high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape stacked together. A thin rectangular channel is formed between various plates for heat exchange through half plates. Plate heat exchangers are ideal equipment for heat exchange between liquid liquid and liquid vapor. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, convenient 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 a tube heat exchanger, occupying one-third of the area of the tube heat exchanger, and the heat recovery rate can reach over 90%.

 

 

The sealing gasket is installed in the sealing groove of the plate and can only achieve the purpose of sealing by being squeezed by the plate. suchThe working principle of the type of sealing is to compress the sealing element to cause elastic deformation, according to the characteristics of the rubber material .When the sealing gasket is subjected to external force, it will generate elastic reaction force due to the need to recover deformation.The contact stress is formed on the sealing surface where the sealing gasket contacts the sealing groove, and the greater the deformation of the gasket, the greater the contact stressThe greater the force. As the pressure of the heat exchange medium increases, the sealing gasket is subjected to the pressure of the medium, which causes its original Continuing to compress and deform on the basis of pre compression will further increase the contact stress on the sealing gasket

 

 

 

1. Heat transfer plate

The heat transfer plate is the main heat exchange element of the heat exchanger. Generally, the corrugation is in the shape of a figure. According to the different fluid media, the material of the heat transfer plate is also different. Most of them are made of stainless steel and titanium.

2.Sealing gasket

The sealing gasket of the plate heat exchanger mainly plays a sealing role between the heat exchange plates. Materials include: nitrile rubber, EPDM rubber, fluororubber, etc. Different rubbers are used according to different media.

3.Pressure plate at both ends

The pressure plates at both ends are mainly used to clamp and compress all heat transfer plates, ensuring that the fluid medium does not leak.

4.Clamping bolt

The clamping bolt mainly serves to tighten the pressure plates at both ends. Clamping bolts are usually double threaded, and when pre tightening the bolts, the torque of the fixing plate is evenly distributed.

5.Hanger

Mainly used to support heat exchange plates, making them easy to disassemble, clean, and assemble.
