Abstract:

A computer cabinet cooling system comprising an upright tower cabinet having a front panel with an equipment bay for holding heat producing components, a lower aperture and a plurality of air openings. A fan unit having a fan plenum is mounted within the lower aperture of the front panel below the equipment bay near the air openings. An inner door is provided having a plurality of air inlet ports, a plurality of air outlet ports, a plurality of spaced apart horizontal air ingress slots and a fan shroud. When the inner door is closed against the front panel, the air outlet ports will align with the air openings in the front panel, the air ingress slots will align with the heat producing components in the equipment bay and the fan shroud will contact the fan unit. An outer door is also provided having an air plenum, a lower orifice with air deflector, and a plurality of spaced apart horizontal air ingress slots. When the fan unit is turned on ambient air will be drawn through the air inlet ports and air outlet ports in the inner door, past the air openings in the front panel, into the fan plenum, out through the fan shroud, past the lower orifice with the air deflector, up through the air plenum in the outer door through the air ingress slots in the outer door, past the air ingress slots in the inner door and into the equipment bay in the front panel to cool the heat producing components in the upright tower cabinet.

International Classification:

H05K 720

US Classification:

165 803

Abstract:

A computer hard drive heat sink assembly 14 having an interior hard drive receiving channel 23 which fits closely adjacent heat transfer surfaces 24, 26 and 32. Connected to one end of the heat sink assembly is a fan enclosure and panel closure member 17. The fans 16 pull ambient air through the front panel access apertures 18 and supply the ambient air across the heat dissipating surfaces of the heat sink assembly.
