An overview,
Plate heat exchanger is a kind of high efficiency, energy saving, compact structure, general heat exchange equipment with its unique advantages is widely used in machinery, electric power, mining, metallurgy, petroleum, chemical, pharmaceutical, shipbuilding, textile, papermaking, food, nuclear industry, ocean development and thermoelectric even central heating and other industrial production department. Can meet all kinds of medium cooling, heating, condensing, enrichment, disinfection and waste heat recovery process requirements.
Second, the structure and characteristic
Plate heat exchanger composed of heat transfer plate, sealing gaskets, pressure plate, clamping bolts and other major parts.

Features:
1, high coefficient of heat transfer: corrugated plate can make the fluid in smaller under turbulent flow velocity, and the general plate heat exchanger heat transfer coefficient of tube and shell heat exchanger is 3 ~ 5 times.
2, cover an area of an area small, light weight, compact structure of plate heat exchanger, heat exchange area per unit volume for 2 ~ 5 times of the tubular heat exchanger; Under the same working condition, the weight is only about 1/5 of the pipe.
3, terminal temperature difference is small, cold and hot fluid of plate heat exchanger in the heat exchanger in parallel flow on heat transfer surface, so that the end of the plate heat exchanger temperature difference is very small, for water to water heat can reach 1 ℃.
4, convenient maintenance, cleaning, heat exchange plate through the clamping force of clamping screw assemble together, when maintenance cleaning, just loosen the clamping screw can unload the plate clean.
5, it is easy to change the heat transfer area or process combination: as long as the increase (or decrease) a few sheets of plate, need to increase (or decrease) could be achieved with the heat transfer area, changing plate arrangement, or replace a few pieces of plate can meet the requirements of process combination, adapt to the new heat transfer conditions.
