Abstract
A computer system includes a mist cooling system. The mist cooling system suspended droplets of dielectric fluid in air to form a mist and conveys the mist to heat producing components of the computer system. The liquid droplets of the mist wet the heat producing components and remove waste heat as part of a phase change from a liquid phase to a vapor phase. Vaporized dielectric fluid is condensed via a heat exchanger in a chassis of the computer system and is returned to a reservoir for use in generating mist.
Claims20
A computer system, comprising:
- a chassis;
- a plurality of heat producing components mounted in the chassis;
- and
- a mist cooling system configured to remove waste heat from the plurality of heat producing components mounted in the chassis,
- wherein the mist cooling system comprises:
- a reservoir positioned in a bottom portion of the chassis;
- a mist generator configured to:
- generate a mist comprising liquid droplets of a dielectric fluid suspended in air;
- one or more tubes coupled with the mist generator, wherein the one or more tubes are configured to direct the mist to one or more of the plurality of heat producing components of the computer system, and wherein the one or more tubes comprise a microstructure on an inner surface of the one or more tubes comprising peaks and valleys configured to prevent the liquid droplets of the mist from coalescing in the one or more tubes;
- and
- a heat exchanger mounted in the chassis configured to condense a portion of the dielectric fluid that has changed phase from a liquid phase to a vapor phase, wherein the portion of the dielectric fluid in the vapor phase has undergone a phase change as part of removing the waste heat from the plurality of heat producing components of the computer system.
