I. Principle of operation
The semi-welded plate heat exchanger is constructed by positioning each of the two corrugated plates back-to-back and laser welding them together as a "box" along a sealing groove designed for the gasket of the semi-welded PHE. The semi-welded plates of the PHE are specifically designed for corrosive media and this construction has a welded seal on one side and a gasket seal on the other, eliminating the risk of corrosion of the seal. Sensitive media flow through the welded flow channels and conventional media flow through the conventional flow channels for heat transfer.
2.the advantages
1、Laser welding a safe and efficient
The use of mature laser welding technology, then sealed with gaskets, high heat transfer efficiency, long service life, not easy to leak, easy access to maintenance, high safety factor.
2、Plate material a high temperature and high pressure resistance
Semi-welded plate heat exchanger plate using 304/316L/titanium plate/hastelloy high strength corrosion-resistant materials pressed, fearless of high corrosion and high temperature media, high pressure 5.0MPA.
3、No bonding rubber gasket design a seal for a long time, high corrosion resistance
As the neoprene sealing gasket has a high corrosion resistance, so the laser half-welded plate heat exchanger using this material as the raw material for the gasket, no bonding system to install the gasket in a specially designed groove, so that the contact area between the gasket and the medium is reduced to a minimum, extending its service life. Seal gaskets also have the advantages of easy cleaning and good resistance to thermal stress.
4、Unique flow channel design to enhance heat transfer
The flow path design can increase the turbulent strength of the media flowing into the plate heat exchanger, enhancing the heat transfer effect and reducing the corresponding pressure loss. In order to meet the requirements of different working conditions, we have different plate types to choose from.
5、Adjustable size for easy disassembly
Simple disassembly, the gasket can be closed plate disassembly for cleaning or cleaning or plate group replacement. Simple installation, simple maintenance. Can be cleaned and repaired, long service life, low running costs. Highly malleable and flexible adjustment. Heat exchange can be adjusted by increasing or decreasing the number of plate sets.
