Plate heat exchanger of composition and function

What are the components of plate heat exchanger and what are the functions of each component?

Plate heat exchanger of composition and function

Plate heat exchanger of overview:

Plate heat exchanger is a new type of high efficiency heat exchanger which is assembled by a series of metal sheet with certain wavy shape.

A thin rectangular channel is formed between the various plates to communicate heat through half of the plates. Plate-type heat exchanger is an interesting equipment for the thermal communication between liquid and liquid and liquid and steam.

It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small land area, convenient equipment cleaning, extensive application, long service life and so on.

In the case of the same pressure loss, its heat transfer coefficient is 3-5 times higher than the tubular heat exchanger, covers an area of one third of the tubular heat exchanger, and the heat recovery rate can be as high as more than 90%.

Plate heat exchanger of elements:

The plate type heat exchanger is mainly composed of heat transfer plate, sealing gasket, pressing plate at both ends, clamping bolt and bracket.

The functions of each component of plate heat exchanger are as follows:

1. Heat transfer plate

Heat transfer plate is the first heat exchanger elements, usually made of corrugated herringbone, according to the fluid medium is not the same, heat transfer plate information is not the same, mostly made of stainless steel and titanium.

2. sealing gasket

The sealing gasket of plate heat exchanger is mainly used to seal between the heat exchange plates. The materials are: nitrile rubber, ethylene propylene diene diene rubber, fluorine rubber, etc., according to different media choose different rubber.

3. both ends of the pressure plate

Both ends of the pressing plate is the first clamping pressure all the heat transfer plate, to ensure that the fluid medium is not leaked.

4. Clamp bolts

The clamping bolt is primarily used for fastening both ends of the platen. The clamping bolt is usually double threaded, so that the torque of the fixing plate is even when the bolt is pretightened.

5. the rack

The first is to support the heat exchange plate, so that it is easy to disassemble, clean, assemble and so on.
