Better effectiveness had been obtained in applying snake-shaped finned flat tubes onto air-cooled units.In order to further enhance the condensing efficiency of air-cooled condensers for the said units
and optimize the structure of finned flat tubes
a three-dimenssional physico-mathematical model of a channel formulated by discontinuously corrugated fin flat tubes has been established.Through comparison and analysis of the convection heat transfer coefficient
heat amount transferred to the air side
and the flow loss etc.
it shows that the discontinuously corrogated fin flat tubes boast certain superiority in aspects of the heat amount transferred to air side and the flow loss as compared with that of the snake-shaped finned flat tubes.
