Abstract: Method of cooling computer equipment that includes pumping coolant into a passageway leading to computer equipment and distributing the coolant from the passageway to heat sinks. The method also includes iteratively adjusting a rate of cooling of electronic devices by the coolant directly or indirectly in dependence upon heat generated by the electronic devices. The method also includes monitoring the respective temperatures of the electronic devices or heat conductive material in thermal contact therewith. The method also includes iteratively calculating the average of the values that said temperatures have at a given time. The method also includes iteratively calculating a spread value indicative of the spread of said values and iteratively adjusting the rate of cooling of the electronic devices by the coolant in dependence upon the ratio of said spread value and a difference between said average and a predetermined maximum acceptable temperature.

Abstract: Method of cooling computer equipment, which equipment comprises a multiplicity of electronic devices with respective heat sinks. The method includes pumping coolant into a passageway leading to the computer equipment and distributing the coolant from the said passageway to the heat sinks. The method also includes iteratively adjusting the rate of cooling of the electronic devices by the coolant which is pumped into the said passageway directly or indirectly in dependence upon the heat generated by the electronic devices. The method also includes monitoring the respective temperatures of the electronic devices or heat conductive material in thermal contact therewith and iteratively adjusting the rate of cooling of the electronic devices by the coolant which is pumped into the said passageway directly or indirectly in dependence upon the said respective temperatures.
