Filed:

Jun 27, 2001

Appl. No.:

09/894192

Inventors:

Himanshu Pokharna - San Jose CA
Eric Distefano - Livermore CA
Joseph D. Walters - Santa Clara CA

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

F25B 1708

US Classification:

62480, 62141, 361688

Abstract:

A computer system is described having a refrigeration cycle for a logic processor each utilizes first and second refrigeration cycles, each including a respective adsorber/desorber. Each adsorber/desorber is alternatingly cooled and heated. A liquid is adsorbed into the adsorber/desorber when being cooled and desorbed when the adsorber/desorber is heated. When the liquid is desorbed from the adsorber/desorber, and a checkvalve is closed, a pressure of the liquid increases. The adsorber/desorber together with the checkvalve act as a compressor in the respective refrigeration cycle. Heating and cooling is alternated so that one adsorber/desorber always adsorbs liquid while the other adsorber/desorber desorbes liquid. Thermal swings of the logic processor are thereby avoided.

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

F28D 1500

US Classification:

16510426, 16510433, 361700, 174 152

Abstract:

A system including a plurality of micro heat pipes is used to transfer heat from a die. A die attach block is coupled with the die. The plurality of micro heat pipes (MHPs) are attached to the die attach block to enable the MHPs to be in close contact with the die to absorb heat generated by the die.

International Classification:

H05K 7/20

US Classification:

361699, 361689, 361690, 361695, 361696, 361697, 361701, 174 151, 174 163, 165 803, 16510433

Abstract:

One embodiment of a modular, scalable cooling system includes a core cooling module configured to be thermally coupled to a heat-generating electronic device and a supplemental cooling module configured to be thermally coupled to the core cooling module. A first interface attached to the core cooling module is configured to thermally couple the core cooling module to the supplemental cooling module. The core cooling module and the supplemental cooling module may be used alone or in combination to dissipate heat from the heat-generating electronic device.

US Classification:

361785, 361742, 361790, 361804

Abstract:

One embodiment of a field changeable graphics system for a computing device includes a graphics card and an interface assembly. The interface assembly is adapted to interface the graphics card with the motherboard of a computing device, without directly mounting the graphics card to the motherboard. One advantage of the disclosed graphics system is that it enables a computing device user to upgrade the existing device's graphics system. Thus, the user is not forced to purchase an entirely new computing device in order to take advantage of graphics innovations. This advantage is particularly significant for users of portable computing devices, such as laptop computers and PDAs.

US Classification:

345520, 345503

Abstract:

One embodiment of a field changeable rendering system includes an output device interfaced to a motherboard, a fixed rendering device mounted to the motherboard for generating information to be output on said output device, a connector for attaching a field-changeable rendering card to the motherboard, said field-changeable rendering card capable of housing a discrete rendering device for generating information to be output on said output device and detection circuitry for detecting that a field-changeable rendering card housing a discrete rendering device is coupled to said connector and causing information from said field-changeable rendering card housing a discrete rendering device to be output on said output device. One advantage of the disclosed edge connector is that it is compatible with a plurality of graphics cards and systems, thereby enabling a computing device user to upgrade the existing device's graphics system. Thus, the user is not forced to purchase an entirely new computing device in order to take advantage of graphics innovations.
