  • Publication number: 20100313590
    Abstract: Liquid-cooled electronics racks and methods of fabrication are provided wherein a liquid-based cooling apparatus facilitates cooling of electronic subsystems when docked within the electronics rack. The cooling apparatus includes a liquid-cooled cooling structure mounted to a front of the rack, and a plurality of heat transfer elements. The cooling structure is a thermally conductive material which has a coolant-carrying channel for facilitating coolant flow through the structure. Each heat transfer element couples to one or more heat-generating components of a respective electronic subsystem, physically contacts the cooling structure when that electronic subsystem is docked within the rack, and provides a thermal transport path from the heat-generating components of the electronic subsystem to the liquid-cooled cooling structure. Advantageously, electronic subsystems may be docked within or undocked from the electronics rack without affecting flow of coolant through the liquid-cooled cooling structure.

  • Publication number: 20100306994
    Abstract: A method of fabricating a multi-fluid cooling system is 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 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.
