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.

Full coverage spray and drainage system and method for orientation-independent removal of high heat flux

A spray cooling system includes a spray delivery device and a cooling liquid delivered to the spray delivery device. The spray delivery device includes one or more inlet apertures and one or more corresponding outlet apertures, at least one pair of inlet aperture and corresponding outlet aperture being positioned relative to each so as to form an asymmetric non-uniform density full-cone spray pattern.

Method and apparatus for cooling electronic components

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.
