Patent ID: 8046113

Claim:
A method for cooling a heat-generating device, comprising: setting a reference surface temperature of the heat-generating device; measuring surface temperatures of the heat-generating device at two or more different locations; measuring a temperature gradient based on temperature measurements of two or more different locations on the heat-generating device; and implementing a closed-loop control based on the reference surface temperature, the average measured surface temperature, and the measured temperature gradient of the heat-generating device to compute a rate of application of a cooling material to the surface of the heat-generating device; computing a dissipated heat of the heat-generating device based on the measured temperature gradient; deriving a critical heat flux (CHF) of the heat-generating device; determining whether the computed dissipated heat plus a tolerance range for the computed dissipated heat is less than the derived CHF; and providing a command to apply the cooling material to the surface of the heat-generating device at the calculated rate to cool the heat-generating device.
