Product Parameters
Plate heat exchanger is a new type of high-efficiency heat exchanger composed of a series of metal sheets (heat exchange plate bundles) with a certain ripple shape and a frame. The heat transfer plate and sealing gasket form a plate bundle, with corner holes at the four corners of the heat transfer plate. The sealing gasket and heat transfer plate are installed in the frame between the fixed pressing plate and the movable pressing plate, and clamped with clamping bolts.

Structural flowchart of plate heat exchanger:
1- Fixed clamping plate, 2- Connection port, 3- Shim, 4- Plate, 5- Active clamping plate, 6- Lower guide rod, 7- Upper guide rod, 8- Clamping bolt, 9- Pillar,
Seal the fluid channels and guide the fluid to flow alternately to their respective channel seals. These connecting pipes are aligned with the channel holes on the same plate and connected to the external pipelines of the two liquids for heat exchange. The heat transfer plate and the movable clamping plate are suspended below the top bearing beam and aligned and positioned by the bottom crossbeam.
The working medium flows through narrow and tortuous channels formed by two adjacent heat transfer plates, and the inter plate flow channel of the plate heat exchanger is a variable cross-section and tortuous flow channel. The corrugated plate not only increases the turbulence level of the fluid, but also reduces the thermal resistance of the liquid film of the fluid; And it forms many support points that are sufficient to withstand the pressure difference of the medium. The use of thin plates with a thickness of 0.5-0.8mm reduces the heat transfer resistance on the wall surface, and there is no bypass, greatly improving its total heat transfer coefficient. When the Reynolds coefficient is greater than 10, the total heat transfer coefficient can reach up to 4000-6000W/(m2 · K). Cold fluid flow between plates in plate heat exchangers

Application scenarios of plate heat exchangers:
1. Refrigeration: used as a condenser and evaporator.
2. HVAC: Intermediate heat exchangers used in conjunction with boilers, high-rise building intermediate heat exchangers, etc.
3. Chemical industry: soda ash industry, synthetic ammonia, alcohol fermentation, resin synthesis cooling, etc.
4. Metallurgical industry: Heating or cooling of aluminate mother liquor, cooling of steelmaking process, etc.
5. Mechanical industry: cooling with various quenching fluids, cooling with lubricating oil for reducers, etc.
6. Power industry: High voltage transformer oil cooling, generator bearing oil cooling, etc.
7. Paper industry: Heat recovery in bleaching process, heating of washing solution, etc.

Comparing to other other types of heat exchanger, plate heat exchangers have larger surface area. They are composed of a number of thin metal plates compressed together. Gasket is attached to the heat transfer plate with forms flow channel and acts seal up the fluid. Different materials have different channels and in their respective flow path alternately. They won't leak to the outside. The number of the heat transfer plate is determined according to the amount of fluid, physical properties of fluid,the pressure drop and thermal condition. Each plate is corrugated to increase the maximum heat transfer area.
