Abstract
A cooling system for use in an enclosure housing heat-emitting electrical and/or electronic apparatus comprises, in combination, a fan unit and, separately formed with respect to the fan unit, a cooling unit 12. The fan unit includes electrically driven fans mounted with their axes vertical and the cooling unit includes open ended tubes arranged side by side with their axes in a horizontal plane and transversely spaced apart to form passages therebetween. One open end of each tube is adjacent the front of the rack and is open to the atmosphere through a grill; the other open end of each tube is spaced inwardly from the rear of the rack and opens into an otherwise fluid-tight compartment in which are housed electrically driven fans and associated deflectors. Air within the enclosure heated by heat emitted by the electrical and/or electronic apparatus is caused to flow upwardly or downwardly by the fans of the fan unit through the passages between the transversely spaced tubes of the cooling unit and is cooled by air initially at ambient temperature which is drawn by the fans of the cooling unit from outside the enclosure through tubes of the cooling unit into the compartment and is deflected by the deflectors through other tubes of the cooling unit and out of the unit.
