The purpose of each part of the plate heat exchanger
The plate heat exchanger is a high-efficiency heat exchanger formed by stacking a series of metal heat exchanger plates with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, wide application, long service life, etc.
The name of each part of the plate heat exchanger and the purpose of the parts will be listed below.
1. Heat exchanger frame
It is mainly to support the heat exchange plate to make it easy to disassemble, clean and assemble.
2. Both ends of the pressure plate
The pressure plates at both ends mainly clamp and press all the heat transfer plates to ensure that the fluid medium does not leak.
3. Clamping bolt
The clamping bolts are mainly used to tighten the pressure plates at both ends. Clamping bolts are generally double-threaded. When the bolts are pre-tightened, the torque for fixing the heat exchanger plates is even.
4. Plate heat exchanger gasket
The gasket of the plate heat exchanger mainly serves as a seal between the heat exchange plates. The materials are: nitrile rubber, EPDM rubber, fluorine rubber, etc., and different materials of rubber are used according to different media.
5. Plate heat exchanger plates
The heat exchanger plates are the main heat exchange parts of the heat exchanger. Generally, the corrugations are made into a V shape. According to the different fluid media, the heat transfer plates are made of different materials. Most of them are made of stainless steel and titanium.
In view of the different functions of different heat exchanger accessories, we can better maintain the plate heat exchanger and let it serve us better.
