Cooling electronic devices in a data center
First Claim
1. A data center cooling system, comprising:
- a server rack sub-assembly that comprises at least one motherboard mounted on a support member and a plurality of heat generating electronic devices mounted on the at least one motherboard;
at least one cold plate mounted on top of and positioned in conductive thermal contact with at least a portion of the plurality of heat generating electronic devices, the cold plate configured to receive a flow of a cooling liquid circulated through a supply conduit fluidly coupled to a liquid inlet of the at least one cold plate, through the at least one cold plate, and through a return conduit fluidly coupled to a liquid outlet of the at least one cold plate; and
a modulating control valve attached to the server rack sub-assembly, the modulating control valve disposed on top of the support member and positioned in either of the supply conduit or the return conduit, the modulating control valve configured to adjust a rate of the flow of the cooling liquid in response to receiving a command from a controller, the command configured to adjust the valve based at least in part on an operating condition of at least one of the plurality of heat generating electronic devices.
