Patent ID: 8109324

Claim:
A microchannel heat exchanger for a heat generating component, comprising: a slurry containing a microencapsulated particulate liquid/solid phase change material operable to melt in a heat range required for cooling the heat generating component; a heat exchanger located or locatable in proximity to the heat generating component to remove heat therefrom, the heat exchanger having a series of microchannels for passage of the liquid slurry, each of the microchannels having a non-linear path, a width of about 50 to about 500 microns, and an aspect ratio of height to width of at least 5:1; the slurry being within the microchannels of the heat exchanger and capsules of the microencapsulated phase change material being of a diameter in the range of about 5 percent to about 20 percent of the microchannel width; and a pump for moving the liquid slurry at flow rate through the heat exchanger; wherein the microchannel heat exchanger has a heat flux capacity of at least 100 W/cm 2 .
