Plate heat exchanger shell and tube heat exchanger heating central air conditioning

- - - - _/__// / /r/ ...bbb . Working principle of plate heat exchanger:
Plate heat exchanger is composed of many corrugated heat transfer plates, arranged at certain intervals. Detachable heat exchange equipment composed of rubber gaskets. When the plates are assembled, the two groups are arranged alternately, and the rubber sealing strips are fixed with adhesive between the plates. Its function is to prevent fluid leakage and form a narrow mesh flow channel between the two plates. The heat exchange plate The sheets are pressed into various corrugated shapes to increase the area and rigidity of the heat exchange plates, and can make the fluid form turbulent flow at low flow rates to achieve the effect of enhancing heat transfer. The four corner holes on the plate form a distribution pipe and a drain header for the fluid. The two heat exchange media flow into their respective flow channels, forming countercurrent or parallel flow through each plate for heat exchange.
Characteristics of plate heat exchanger:
. Large logarithmic average temperature difference.
. Small footprint, compact structure, easy to clean.
3. Light weight, the thickness of the plate is generally...
. The heat transfer coefficient is high, and the corrugations of the plates can cause turbulence in the fluid at a smaller flow rate.
. The heat exchange area or process combination can be changed. The required heat exchange area can be achieved by increasing or reducing the number of plates. Changing the arrangement of the plates can be applied to different heat exchangers.
. Low price.
