Are the corrugations between the heat exchanger plates in contact with each other? How is the flow channel specifically formed?
Avoid contact; the purpose of the corrugated plate is to increase the heat exchange area
For point contact, if you can’t imagine what the flow channel should look like, take two washboards and place them together intersectingly – that constitutes the flow channel in a plate exchanger
It’s a very vivid metaphor; it seems quite familiar.
It is not intended to increase the heat exchange area (although objectively the heat exchange area does increase; however, the calculation of this area is based on the area of the unpressed plate)~~~ It is done to enhance the pressure resistance between the plates and to create flow channels~~~)
I agree with you; shouldn’t there also be an enhancement of heat transfer?
Since the surface area increases, it has the effect of enhancing heat transfer.
By enhanced heat transfer, I do not mean an increase in area; rather, it refers to the improvement of the flow pattern of the medium, which in turn increases the heat transfer coefficient.
Correct, low-pressure turbulence – one of the characteristics of plate exchangers~~~~~~~~~~~~~~
