The heat exchange plate of the fully welded plate heat exchanger is made of special stainless steel and pressed with a special mold. The surface is smooth and not easy to scale. Its unique corrugated design enables the fluid to generate turbulent flow even at low flow rates, and has high heat transfer efficiency. It does not use any non-metallic sealing material, so it has high temperature resistance and pressure resistance. It can be applied to extreme working conditions of high temperature and high pressure.
What are its characteristcs?
1. High heat transfer efficiency
In the plate bundle, the all-welded plate heat exchanger adopts a Plate And Frame Heat Exchanger. Its complex fluid flow pattern can be generated by changing the shape and spacing of the plates, thereby exerting its heat transfer to a certain extent. When the Reynolds number is several hundred, the turbulent flow effect can be achieved and high heat transfer performance can be obtained.
2. Small pressure loss
The unique plate structure can make the fluid fill the flow channel formed by the plate. In this case, all the plate surfaces are involved in heat exchange. In the flow channel, the medium can flow without dead zone, and then in a certain extent, the consumption of kinetic energy can be reduced, and the operating cost can be further saved.
3. Not easy to scale
After the corrugated plate is welded around it, it is affected and restricted by thermal stress during operation, which causes the inner side of the plate to expand and contract freely, and it is not easy to form a scale layer on the surface of the plate.
4. Compact structure and small footprint
The fully welded plate heat exchanger has a compact structure, a wide range of expansion and contraction for applicable space conditions, and can be freely exchanged. The heat exchange area per unit area is 2-5 times that of the Shell And Tube Heat Exchanger, and there is no need to reserve the maintenance space for drawing out the tube bundle. When the same heat exchange task is realized, the floor space of the all-welded plate heat exchanger is about It is 1/6-1/10 of the shell and tube heat exchanger, which can greatly reduce the capital investment cost.
