Patent ID: 8104533

Claim:
A method of removing heat from a heated surface, comprising: providing a mixing chamber; guiding a primary fluid to the mixing chamber; guiding a secondary fluid to the mixing chamber, wherein the secondary fluid enters the mixing chamber with a direction of travel which causes the secondary fluid to interact with the primary fluid, wherein the interaction of the secondary fluid with the primary fluid causes destabilization of the primacy and/or the secondary fluid; discharging a combined flow of the primary fluid and the secondary fluid through a discharge port of the mixing chamber, wherein the combined flow of the primary fluid and the secondary fluid is atomized upon exiting the discharge port; and spraying the combined flow of the primary fluid and the secondary fluid exiting the mixing chamber through the discharge port onto a heated surface, wherein the combined flow sprayed onto the heated surface absorbs heat from the heated surface and carries the absorbed heat away as the combined flow leaves the heated surface, wherein guiding a primary fluid to the mixing chamber comprises guiding the primary fluid to the mixing chamber via at least one primary fluid channel, wherein guiding a secondary fluid to the mixing chamber comprises guiding the secondary fluid to the mixing chamber via at least one secondary fluid channel, further comprising: providing an inner nozzle portion, wherein the at least one primary fluid channel allows primary fluid to flow through the inner nozzle portion; and providing an outer nozzle portion, wherein an outer surface of the inner nozzle portion has at least one groove cut into the outer surface, wherein the inner nozzle portion is inserted into a cavity of the outer nozzle portion such that an inner surface of the outer nozzle covers a portion of each groove cut into the outer surface of the inner nozzle portion to form one of the at least one secondary fluid channel, wherein a portion of the cavity of the outer nozzle portion remaining after insertion of the inner nozzle portion into the outer nozzle portion, surrounded by the inner surface of the outer nozzle portion and the outer surface of the inner nozzle portion, forms the mixing chamber.
