I would like to ask experts about the pressure drop of DR finned tube air-to-air heat exchangers
Thread Content
The company plans to build a simple air cooler (for heat and cold air exchange), with hot air flowing through the tube side and cold air flowing through the shell side. It is planned to use DR-type finned tubes with DN25 pipes; it is not clear what the appropriate gas velocity for the tube side design should be, nor what the tube side resistance will be. Operating pressure: negative pressure,
An egg went swimming in the river, and as a result it turned into a nuclear bomb (in the river)；
Why are gas-to-gas heat exchangers made in a tubular design? Why not use a plate-type design? Tubular types have large volumes, poor heat exchange efficiency, and it is difficult to address the issue of thermal expansion when temperatures are high.
