  • Patent number: 7808787
    Abstract: A heat spreader having at least two adjoining strips of pyrolytic graphite material is made by cutting a strip from a sheet of pyrolytic graphite in the z direction. Thermal conductivity in the xy plane of the graphite sheet is greater than in the z direction. The z direction cut provides strips which are then each individually oriented 90 degrees such that the thickness direction of the original pyrolytic graphite sheet becomes the width or length of the cut strip. A face on the side of a first strip adjoins a face on the side of a second strip. Due to the greater thermal conductivity in the xy plane of the strips as compared to in the z direction heat transfers more rapidly in the length and thickness direction of the strips than across adjoining sides of the oriented strips.

  • Patent number: 7796384
    Abstract: In a system for housing electronics cards, methods and systems for cooling the electronics cards are presented. Each electronics card preferably contains heat-producing electronics and a heat sink, and is preferably placed within a card guide of the chassis and secured into position with a clamping device. At least one of the heat sink, the card guide, the clamping device, and a cold wall of the chassis are used to facilitate the conduction cooling of the heat-producing electronics. Furthermore, a clamping device may rigidly secure a card into position, thus reducing the impact of vibrations (including shock) on the card. Additionally, an air flow further cools the electronics cards, the card guides, and/or the cold wall.

  • Patent number: 7773378
    Abstract: A heat-dissipating structure for the expansion board architecture is provided. A fixing element disposed on the heat-absorbing substrate fixes the motherboard and the first expansion board. The heat-generating elements on the motherboard or the first expansion board are directly in touch with the heat-absorbing surface of the heat-absorbing substrate to absorb their heat. The heat-dissipating board extended from the side of the heat-absorbing substrate then dissipates the heat absorbed by the heat-absorbing substrate. The structure thus solves the problems that existing heat-dissipating structures occupy larger space and therefore cannot be effectively used in an expansion board architecture to dissipate heat produced by the heat-generating elements between the motherboard and the expansion board and that it is likely to have assembly tolerance. Using the structure can reduce the space and the assembly tolerance, but effectively enhance heat dissipation in the expansion board architecture.

  • Patent number: 7764498
    Abstract: A reconfigurable high performance computer occupies less than 360 cubic inches and has an approximate compute power of 0.7 teraflops per second while consuming less than 1000 watts. The computer includes a novel stack of semiconductor substrate assemblies. Some semiconductor substrate assemblies involve field programmable gate array (FPGA) dice that are directly surface mounted, as bare die, to a semiconductor substrate. Other semiconductor substrate assemblies of the stack involve bare memory integrated circuit dice that are directly surface mounted to a semiconductor substrate. Elastomeric connectors interconnect adjacent semiconductor substrates proceeding down the stack. Tines of novel comb-shaped power bus bar assembly structures extend into the stack to supply DC supply voltages. The supply voltages are supplied from bus bars, through vias in the semiconductor substrates, and to the integrated circuits on the other side of the substrates.
