Plate and shell heat exchanger
The large plate and shell heat exchanger uses the plate to transfers heat, the board ties between the slab to use the advanced special-purpose program control automatic argon arc welding machine to carry on the welding, entire welding type board plates in pressure shell. The plate has" calmly stirs" function, which can form the rapids under the very low Reynold's number, also the dirt coefficient is low, the efficiency of heat transfer is 2-3 times of regular shell and tube heat exchangers. Compares with the shell and tube heat exchanger, it has advantage: the compact structure, the light weight, the high efficiency heat transfer, small temperature difference between the cold end and the hot side. It can actual operate ¡°truly adverse current¡± heat exchange. Application: refines oil, petrochemical industry, power plant.
