ABSTRACT:
Method and apparatus for improving convective heat transfer by mechanically stirring fluid over the outer surface of a heat exchanger. A stirring mechanism is described which revolves rapidly around a heat exchanger surface in a stream undergoing heat transfer. During rotation, the stirring mechanism is supported near an end of the stirred heat exchanger by a central bearing and drive means. It is also supported over an extended length of the stirred heat exchanger surface by the hydrodynamic action of the stirring mechanism relative to the heat exchange surface without need for an additional central support bearing. The stirring mechanism uniformly turbulates the fluid film over the outer surface of the heat exchanger where heat transfer resistance normally occurs without imposing a pressure drop in the fluid stream undergoing augmented heat transfer. Compact and inexpensive heat exchangers are described which may be used in refrigeration, heating-cooling, and energy conservation systems. They offer special advantages where the temperature differential available for convective heat transfer is low and where it is necessary to recover sensible and latent heat energy from combustion products or dirty gaseous streams. Economizer units are described which may retrofit existing heating systems and recover most of the sensible and latent heat energy which these systems now waste in flue products. Special draft control features of these units also allow the adapted heating systems to operate with nearly identical steady-state and seasonal efficiencies.
