Patent ID: 8587943

Claim:
A computer memory system comprising: a plurality of memory modules sockets spaced apart on a system board configured for receiving a plurality of memory modules, each memory module socket configured for releasably receiving a card edge connector of a memory module of the plurality of memory modules; a liquid flow assembly including a first block having a liquid flow passage, a second block having a liquid flow passage, a chilled liquid source in fluid communication with the blocks, and a plurality of heat transfer pipes thermally coupling the first block to the second block, the heat transfer pipes extending along the system board between the memory module sockets from the first block to the second block; and a plurality of heat spreaders, each heat spreader having a pair of parallel plates in thermal engagement with opposing faces of a respective one of the memory modules and a ridge extending transversely outwardly from at least one of the plates to thermally engage an adjacent one of the heat transfer pipes, wherein along a length of the adjacent one of the heat transfer pipes extending from the first block to the second block, the ridge on a first one of the heat spreaders positioned on a first one of the memory modules is interleaved with the ridge on a second one of the heat spreaders positioned on a second one of the memory modules adjacent the first one of memory modules, such that the ridge from the first one of the heat spreaders thermally engages a first part of the adjacent one of the heat transfer pipes and not a second part of the adjacent one of the heat transfer pipes, and the ridge from the second one of the heat spreaders thermally engages a second part of the adjacent one of the heat transfer pipes and not a first part of the adjacent one of the heat transfer pipes.
