Abstract
An enhanced heat transfer system for integrated circuit modules utilizing a parallel finned heat sink integrated with rotating disk fan(s). The disk fan may also be used between printed circuit cards. The addition of holes and/or protuberances to the rotating disk further enhances the heat transfer by disturbing the thermal boundary layer of the heat sink or modules.
Claims10
An air cooling system for integrated circuit packages which tend to collect particles and heat the air adjacent to said circuit packages during operation comprising:
- a circuit package having a plurality of heat dissipative surfaces on members to be cooled, which surfaces are aligned in spaced substantially parallel planes which are mounted on and perpendicular to a base support surface;
- a plurality of heat transfer disks and means for mounting said heat transfer disks for rotary movement adjacent to said heat dissipative surface;
- said means for mounting said heat transfer disks including a disk drive shaft coupled to a motor, said disk drive shaft substantially parallel to the base support surface;
- said heat transfer disks being mounted on said disk drive shaft at spaced locations such that a surface of said heat transfer disks is interposed in the space between said spaced substantially parallel planes proximate to and between said heat dissipative surfaces, and while continuously rotating said heat transfer disk removes said particles and said heat from the air adjacent to said circuit package.
An air cooling system for integrated circuit packages which tend to collect particles and heat the air adjacent to said circuit packages during operation comprising:
- a circuit package having a heat dissipative surface;
- said circuit package including in combination,
- (a) plurality of printed circuit cards having means for connection to other circuits of an electrical system;
- (b) said printed circuit cards connected to said other circuits such that said printed circuit cards are substantially parallel to each other and normal to said other circuits;
- (c) said printed circuit cards having at least one package housing mounted thereupon;
- and
- (d) said package housing containing a plurality of integrated circuits within the housing which produce heat during operation;
- a plurality of heat transfer disks and means for mounting said heat transfer disks for rotary movement adjacent to said heat dissipative surface;
- said means for mounting said heat transfer disks including a disk drive shaft coupled to a motor;
- said heat transfer disks being mounted on said disk drive shaft at spaced locations such that a surface of said heat transfer disks is proximate said heat dissipative surface, and while continuously rotating said heat transfer disk removes said particles and said heat from the air adjacent to said circuit package.
