Abstract
A compact and efficient spray cooling system is provided for cooling a heat source or a plurality of heat sources. The system uses at least one atomizer arranged in an array to deliver a fine spray across a wide distribution to impinge upon the surface to be cooled. The spray maintains a thin liquid film upon the cooled surface where heat is transfered in a phase change process. The liquid and vapor resulting from the heat transfer process is removed from the system at the edges of the heat source(s) and uses the momentum of the original spray to move the vapor and liquid to a fluid removal port. The use of the momentum of the spray to remove the liquid from the system allows the system to be gravity independent and used in transportation, avionics, and spacecraft applications where adverse gravity conditions exist. The atomizer array can be spaced closely to the heat source because the individual atomizers develop the spray in a relatively short distance. This allows the entire cooling system to be arranged in a compact and efficient package with wide ranging applications.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
