Abstract:
1. An electronic component enclosure cooling system comprising: an enclosure located in a room of conditioned air, the enclosure comprising a cabinet and an access door thereto, the cabinet adapted to operatively house at least one substantially horizontal row of spaced apart, substantially vertically oriented electronic component boards; a plurality of electronic component boards disposed in the at least one row within the cabinet; an air mover system within the cabinet and adapted to draw the conditioned air into an opening in the enclosure, through the at least one row of boards, out an exit in the enclosure and back into the room; a first air-to-fluid heat exchanger located within the cabinet and between the opening and the first row of boards and adapted to remove a portion of the heat from the conditioned air before the air passes through the first row; a second air-to-fluid heat exchanger located within the cabinet between the exit and the at least one row of modules and adapted to remove a portion of the heat from the air before is returned to the room; and a pump system for pumping a two-phase refrigerant through the plurality of heat exchangers such that the air exiting the enclosure is substantially the same temperature as the conditioned air entering the enclosure.
