INTEGRATED CIRCUIT CHIP COOLING DEVICE |
摘要 |
An integrated circuit chip cooling device includes a network of micropipes. A first pipe portion and a second pipe portion of the network are connected by at least one valve. The valve is formed of a bilayer strip. In response to change in temperature, the shape of the bilayer strip changes to move the valve from a substantially closed position to an open position. In one configuration, the change is irreversible. In another configuration, the change is reversible in response to an opposite change in temperature. |

1. A device for cooling an integrated circuit chip, comprising:
a network of micropipes including pipe portions; wherein said pipe portions are connected by valves, each valve comprising at least one bilayer strip; and wherein said micropipe network comprises:
a first network of interconnected trenches located in a first substrate, anda second network of interconnected trenches located in a second substrate stacked to the first substrate and separated from the first substrate by a stack of two layers of different materials having different thermal expansion coefficients. |
