This disclosure is directed to a heat exchanger which includes a coil through which a heat exchange medium is circulated, the coil being located in one of a pair of chambers, a fan in the same chamber as the coil but located therebeneath, a partition separating the two chambers with an opening therein through which air driven by the fan can be drawn from the first chamber and introduced into the second chamber, and a door normally closing the second chamber and hinged to open under the influence of air emitted from the fan to thereby effectively create air flow during a non-heat-augmented operation of the heat exchanger.

A housing for a heat exchanger comprising a generally upstanding peripheral wall, partition means for setting off a pair of chambers within said housing, first means for admitting ambient air from the exterior of said housing into a first of said pair of chambers, second means for admitting air from a second of said pair of chambers to the exterior of said housing, third means for admitting ambient air from the exterior of said housing into said second chamber, means for normally closing said second air admitting means, and means for creating air flow along first and second flow paths in said respective first and second chambers and conducting air along said first flow path from said first chamber into said second chamber and thereafter directing the air toward said closing means to open said closing means and maintaining it opened under the combined effects of the air flow of both flow paths to effectively discharge air of both flow paths from said second chamber through said second air admitting means to atmosphere.
