OSTI ID:10142889
Excellent thermal performance of a silicon microchannel heatsink is demonstrated using liquid nitrogen as the coolant over a wide range of heat loads up to 1 kW/cm{sup 2}. This performance is partly due to the order of magnitude increase in the thermal conductivity of silicon near 77 {degree}K compared to room temperature. Subcooled boiling of the liquid nitrogen in the microchannel heatsink further enhances the thermal performance but makes the thermal resistance a nonlinear function of heat load. For a 500 W/cm{sup 2} heat load, a thermal resistances of 0.052 cm{sup 2*0}C/W for a 9:1 aspect ratio heatsink was measured.
