1. A gas cooling device for cooling a heat source with a gas that is cooler than the heat source, the gas cooling device comprising:
a parallel microchannel array cooler comprising:
a base for transferring heat from the heat source; andone or more rows in a widthwise direction, a first row of the one or more rows for receiving a plurality of linearly arranged jets of the gas and comprising fins in a lengthwise direction running a length of the first row and that are separated by evenly spaced microchannels, the fins for dissipating the heat from the base, each of the fins being between two of the evenly spaced microchannels and having a bottom edge adjacent to the base, the bottom edges of the fins each having an indentation to connect the two of the evenly spaced microchannels to create a micro-plenum running the length of the first row in the lengthwise direction between the fins and the base for receiving the plurality of linearly arranged gas jets at a corresponding plurality of linearly arranged receiving points, directing the linearly arranged gas jets along the base in the lengthwise direction, and dispersing the gas to the fins via the evenly spaced microchannels in the widthwise direction, one of the evenly spaced microchannels being between two adjacent ones of the linearly arranged receiving points and for receiving the directed gas through the micro-plenum from each of two corresponding adjacent ones of the linearly arranged gas jets, the gas for transferring the heat from the fins; and a manifold separated from the cooler by an air gap extending across an entirety of a top of the cooler, the manifold comprising:
a plurality of linearly arranged nozzles corresponding to the plurality of linearly arranged gas jets and for delivering the corresponding linearly arranged gas jets to the first row, each of the linearly arranged nozzles for delivering a corresponding one of the linearly arranged gas jets across the air gap to a corresponding one of the linearly arranged receiving points in the micro-plenum; andopenings for removing the gas delivered to the cooler. |
