Patent ID: 7808783

Claim:
A computer system comprising: a first multiple chip module (MCM); a second MCM positioned adjacent said first MCM; a first evaporator thermally coupled to said first MCM, said first evaporator including a first expansion orifice; a second evaporator thermally coupled to said second MCM, said second evaporator including a second expansion orifice; a condenser thermally coupled to said first evaporator and said second evaporator; a first cooling loop coupled between said condenser and said first evaporator, said first cooling loop having a first expansion valve; a second cooling loop coupled between said condenser and said second evaporator, said second cooling loop having a second expansion valve; and, a refrigeration controller operably coupled to said first expansion valve and said second expansion valve, said refrigeration controller having a processor responsive to executable computer instructions when executed on said processor for determining increase in demand of said first MCM and transmitting a first signal to said second expansion valve to increase a first operating temperature of said second evaporator in response to said determining of increased demand.
