  • Patent number: 7969736
    Abstract: DIMMs are cooled by positioning a thermally conductive base between adjacent DIMMs. The thermally conductive base, such as a heat pipe or metal rod, receives heat from the DIMMs through thermally conductive elements that are selectively biased outward against the installed DIMMs. The base transfers the heat to a liquid conduit extending along the end of the DIMMs, where a circulating liquid carries away the heat. The thermally conductive elements provide an adjustable span to accommodate variations in distance between the DIMM surfaces. Embodiments of the invention may be installed without extending above the height of the DIMM.
