Abstract

A gravity cooling unit having at least one pair of cooling columns with each column having a plurality of cooling fins mounted on one more serpentine cooling coils carrying a refrigerant. The unit has mounting means for use in mounting the unit against a ceiling. The pair of cooling columns are fixed to the mounting means to have the long axis of their fins angled toward each other to form a downwardly diverging air space between them, and to have the short, upper side of their fins adjacent the ceiling, when the unit is mounted on the ceiling, to minimize air flow between the columns and the ceiling.
