摘要： A cooling system and method that significantly improves spray evaporative cooling by using arrays of slot or plane sprays to create coverage of the entire heated surface to be cooled without allowing interaction between plumes that are spraying from the nozzles. The sprays are directed at an angle to the surface to take advantage of the high droplet momentum possessed by the spray to direct a flow of coolant fluid across the surface toward desired draining points, thereby enabling drainage regardless of the orientation of the unit.

摘要： Disclosed are methods and apparatuses for cooling a work piece surface using a dual-loop cooling system. The system includes a vapor-compression loop and a liquid-evaporation loop. The loops are configured to prepare a coolant at or approximately at saturation for delivery into a chamber for cooling the surface. A preferred liquid-evaporation loop includes a chamber, a phase separator, a liquid pressurizer, and a vapor mixer that heats the coolant to or near its saturation temperature. A preferred vapor-compression loop includes the phase separator, a compressor, a condenser, an expansion valve, and a return line. The vapor mixer preferably heats the coolant by mixing liquid coolant with vapor coolant derived from the vapor-compression loop. A two-phase flow detector may be disposed downstream of the vapor mixer and be in communication with a vapor valve disposed upstream of the vapor mixer to ensure that an appropriate amount of vapor is fed into the vapor mixer to induce evaporation. Methods include cooling a surface by cycling a coolant through the liquid-evaporation loop and preparing the coolant at saturation with vapor derived from the vapor-compression loop.

摘要： A cooling system and method that significantly improves spray evaporative cooling by using a mixture of cooling fluids having different boiling points. The cooling fluid mixture is sprayed onto a surface to be cooled. Efficient cooling with reduced cooling fluid volume is provided by both evaporation of the more volatile component of the mixture as well as heating of the less volatile component which remains in contact with the surface being cooled. More uniform temperatures across the surface being cooled and a reduced risk of potentially damaging critical heat flux is achieved.

摘要： An emulsion tube for a carburetor is formed with a porous wall surrounding an inner passage, wherein air travels about one side of the wall and fuel travels about the opposite side, with air being supplied through the pores to aerate the fuel (with the aerated fuel then being expelled into a venturi wherein engine intake air is traveling to further mix the fuel with the intake air therein). The emulsion tube can beneficially provide a high degree of fuel/air mixing across the entire range of intake airstream flow rates at which an engine may operate. The porosity of the emulsion tube can also be tailored to provide the desired fuel/air ratio(s) across the engine's operational range of intake airstream flow rates.

摘要： Disclosed are methods and apparatuses for cooling a work piece surface using two-phase impingement, such as direct jet impingement. Preferred methods include flowing a coolant through a chamber comprising a surface to be cooled by projecting a jet stream of coolant against the surface while maintaining pressure in the chamber to permit at least a portion of coolant contacting the surface to boil. Preferred apparatuses include a chamber comprising the surface and tubular nozzles configured to project a stream of coolant against the surface, a pump for forcing coolant through the tubular nozzles, a pressurizer for maintaining an appropriate pressure in the chamber, and a heat exchanger for cooling the coolant exiting the chamber. The apparatuses may further include a pressure regulator for detecting changes in temperature of the coolant exiting the chamber and communicating with the pressurizer to adjust the maintained pressure accordingly. The methods and apparatuses disclosed herein provide for effective and efficient cooling of work piece surfaces.
