A multi-fluid cooling system and methods of fabrication thereof are provided for removing heat from one or more electronic devices. The cooling system includes a multi-fluid manifold structure with at least one first fluid inlet orifice and at least one second fluid inlet orifice for concurrently, separately injecting a first fluid and a second fluid onto a surface to be cooled when the cooling system is employed to cool one or more electronic devices, wherein the first fluid and the second fluid are immiscible, and the first fluid has a lower boiling point temperature than the second fluid. When the cooling system is employed to cool the one or more electronic devices and the first fluid boils, evolving first fluid vapor condenses in situ by direct contact with the second fluid of higher boiling point temperature.
