|20120087088||MICROSCALE HEAT TRANSFER SYSTEMS - This disclosure concerns micro-scale heat transfer systems. Some systems relate to electronics cooling. As one example a microscale heat transfer system can comprise a microchannel heat exchanger defining a plurality of flow microchannels fluidicly coupled to each other by a plurality of cross-connect channels. The cross-connect channels can be spaced apart along a streamwise flow direction defined by the flow microchannels. Such a configuration of flow microchannels and cross-connect channels can enable the microchannel heat exchanger to stably vaporize a portion of a working fluid when the microchannel heat exchanger is thermally coupled to a heat source. Microscale heat transfer systems can also comprise a condenser fluidicly coupled to the microchannel heat exchanger and configured to condense the vaporized portion of the working fluid. A pump can circulate the working fluid between the microchannel heat exchanger and the condenser.||04-12-2012|
|20100032150||MICROSCALE COOLING APPARATUS AND METHOD - A method and system for providing a heat sink assembly are described. The assembly includes a two-phase heat sink, a condenser, and a pump. The two-phase heat sink may include flow micro-channels that accommodate the flow of boiling coolant and cross-connect channel(s) that at least partially equilibrate a pressure field for the boiling coolant. The condenser receives coolant from the heat sink and removes heat. The pump drives coolant through the assembly. In one aspect, the assembly is a closed system for the coolant. In another aspect, the condenser includes first and second plates and a heat exchange surface there between. Coolant flows from the heat sink and through the plates. The gaseous coolant passes the heat exchange surface. In one aspect the gaseous coolant flows opposite to the direction coolant flows. In one aspect, at least one of the plates includes dummy channel(s) for insulating part of the plate(s).||02-11-2010|
