High heat transfer efficiency
In the plate structure, a special corrugated structure shape and spacing are adopted, and the fluid flow pattern is complex, and strong turbulence can be generated at a lower flow rate, so that the heat transfer ability can be exerted to a certain extent and higher The heat transfer performance.
Wide range of application
Its special all-welding process does not require non-metallic materials for sealing, and its structural design is diversified, which can be applied at higher temperatures and pressures.
Low pressure loss
The special plate corrugated structure makes the fluid fill the flow channel formed between the plates, and all the plate surfaces participate in heat exchange. The medium can flow without dead zones in the flow channel, which can reduce the consumption of kinetic energy to a certain extent and save operating costs.
Compact structure, small footprint
The fully welded plate heat exchanger has a compact structure and a wide range of applicable space conditions. The heat exchange area per unit area is 2 to 5 times that of the shell-and-tube type, and there is no need to reserve maintenance space for extracting the tube bundle. When realizing the same heat exchange task, the area of the fully welded plate heat exchanger is about 1/6-1/10 of that of the shell-and-tube heat exchanger, which can greatly reduce the capital investment cost.
Not easy to scale
The heat exchange plates are welded around, and during operation, they are affected and restricted by thermal stress, so that the inside of the plates can expand and contract freely, so the surface of the plates is not easy to scale.
