Product description:
As the above figure indicates, in an induced draft air cooled heat exchanger, the fans are placed above the tube bundles. Ambient air is induced from the top and discharged at the bottom after heat transfer with the process fluid. This type is mostly used as wet air cooled heat exchanger with advantages in reducing the possibility of recirculation of hot air and less influence of the external environment compared with the forced draft air cooler.
Detailed features of air-cooled heat exchanger:
· Fans are located above the bundle
· Air is pulled across the finned tube surface
· Since air velocity approaching the bundle is relatively low, it provides more even distribution of air across the tube bundle
· Better suited for exchangers designed for a close approach of product outlet temperature to ambient-air temperature
· Less likely to recirculate the hot exhaust air, since the exit air velocity is much higher than the forced-draft unit
· In a service in which sudden temperature change would cause upset and loss of product, the induced-draft unit gives more protection in that only a fraction of the surface (as compared with the forced draft unit) is exposed to rainfall, sleet, or snow.
· Will transfer more heat by natural convection with fans off because of the stack effect.
