Abstract: Housing with directed-flow cooling (10) for computer (110) provides auxiliary airflow for cooling a heat-sensitive component, such as CPU (120). Housing (10) includes partition (60) that separates housing (10) into a lower compartment (40) for enclosing computer (110) and an upper compartment (20) for receiving ambient air through slots (24). Partition (60) includes vent opening (61) above CPU (120) that allows air to flow from upper compartment onto CPU (120), directed by impingement fan (50).

Abstract: A cooling device for an electronic component, such as a computer processor, generally comprises a heat sink and a plurality of fans. The fans are redundant in that sufficient cooling is supplied should one fan fail. The fans are independently powered and are inspectable and independently replaceable in situ without un-powering the other fan or the processor. The heat sink includes a base plate having a bottom for surface contact with the processor, a front row of fins projecting upward from the front of the base plate and a rear row of fins projecting upward from the rear of the base plate. A plurality of fans are mounted substantially within a cavity between fan rows. Each fan blows a flow of air such that the flow impinges on the base plate.

Abstract: A cooling device for an electronic component, such as a computer processor, generally comprises a heat sink and a pair of fans. The fans are redundant in that sufficient cooling is supplied should one fan fail. The fans are independently powered and are inspectable and independently replaceable in situ without un-powering the other fan or the processor. The heat sink includes a base plate having a bottom for surface contact with the processor, a front row of fins projecting upward from the front of the base plate and a rear row of fins projecting upward from the rear of the base plate. Right and left fans are mounted substantially within a cavity between fan rows. Each fan blows a flow of air such that the flow impinges on the base plate.

Abstract: A retrofit power supply/fan unit for IBM PC and XT personal computers achieving lower operating temperatures. The unit is contained in a sub-housing positioned in a rear upper corner of the computer housing. The sub-housing has a rear exhaust opening and the computer housing has generally oppositely disposed air inlet openings. The sub-housing has a top wall with its uppermost portion spaced from the underside of the top of the computer housing about 5/8" and the top wall of the sub-housing having a forward sloping top wall portion downwardly sloping at an angle of about 10.degree. to the horizontal as it extends forwardly to facilitate air flow thereto. A pair of juxtaposed fan openings disposed in the forward sloping top wall portion and a pair of fans in the sub-housing aligned with the juxtaposed fan openings to draw air through the sub-housing, each fan being rated at about 32 cfm.
