Abstract:
1. A method for cooling electronics disposed in an environment having an ambient pressure, the method comprising: providing a coolant comprising one of pure water or pure methanol; bringing the electronics into direct contact with the coolant, so that the coolant boils and vaporizes to thereby absorb heat from the electronics; purifying the coolant while at a subambient pressure in order to maintain the purity of the coolant at a level so the coolant has an electrical resistivity greater than one million Ohms-cm; and wherein purifying the coolant while at the subambient pressure in order to maintain the purity of the coolant at the level so the coolant has the electrical resistivity greater than one million Ohms-cm comprises purifying the coolant, using a filtration bed, while at the subambient pressure in order to maintain the purity of the coolant at the level so the coolant has the electrical resistivity greater than one million Ohms-cm.
