Patent ID: 7787248

Claim:
A cooling system comprising: a multi-fluid manifold structure comprising at least one first fluid inlet orifice and at least one second fluid inlet orifice for concurrently separately injecting at least one first fluid stream and at least one second fluid stream towards a surface to be cooled to cool at least one electronic device comprising or coupled to the surface to be cooled; and wherein the first fluid stream is a jet stream, remaining a coherent stream until impinging on the surface to be cooled, and the second fluid stream surrounds the first fluid stream, the first fluid and the second fluid being immiscible, and the first fluid having a lower boiling point temperature than the second fluid, and wherein the cooling system is employed to cool the at least one electronic device via, in part, the first fluid boiling upon impinging on the surface to be cooled, with evolving first fluid vapor condensing by direct contact with the second fluid stream of higher boiling point temperature.
