Abstract:
1. A cooling system for a multi-component electronics system comprising at least one primary heat generating component to be cooled and at least one secondary heat generating component to be cooled, the cooling system comprising: a liquid-based cooling subsystem comprising at least one liquid-cooled cold plate configured to couple to the at least one primary heat generating component to be cooled of a multi-component electronics system, the liquid-based cooling subsystem further comprising at least one thermally conductive coolant-carrying tube coupled to and in fluid communication with the at least one liquid-cooled cold plate for facilitating passage of liquid coolant through the at least one liquid-cooled cold plate; a thermally conductive auxiliary structure coupled to the at least one thermally conductive coolant-carrying tube and configured to couple to the at least one secondary heat generating component to be cooled, wherein when the cooling system is in use with the at least one liquid-cooled cold plate coupled to the at least one primary heat generating component to be cooled and the thermally conductive auxiliary structure coupled to the at least one secondary heat generating component to be cooled, the thermally conductive auxiliary structure provides conductive heat transport from the at least one secondary heat generating component to the at least one thermally conductive coolant-carrying tube coupled thereto, and hence via convection to liquid coolant passing therethrough; and at least one air-cooled heat sink configured to couple to the at least one secondary heat generating component to be cooled, the at least one air-cooled heat sink comprising a plurality of thermally conductive fins, and wherein the cooling system further comprises multiple thermally conductive auxiliary structures, each thermally conductive auxiliary structure comprising a rectangular-shaped structure surrounding a thermally conductive coolant-carrying tube of the at least one thermally conductive coolant-carrying tube, and at least partially aligned over and coupled to the at least one air-cooled heat sink when the cooling system is employed to cool the multi-component electronics system, with the at least one air-cooled heat sink coupled to the at least one secondary heat generating component to be cooled.
