Abstract:
1. A cooling apparatus for an electronics assembly comprising a substrate supporting multiple heat generating electronics components, the cooling apparatus comprising: multiple discrete cold plates, each cold plate having a first surface configured to couple to a respective electronics component of the multiple electronics components, and each cold plate being a coolant-cooled cold plate including a coolant inlet and a coolant outlet with at least one coolant chamber disposed between the coolant inlet and the coolant outlet; a plurality of coolant-carrying tubes, each cold plate having at least two coolant-carrying tubes of the plurality of coolant-carrying tubes extending from a second surface thereof, each coolant-carrying tube being in fluid communication with one of the coolant inlet and the coolant outlet of the cold plate from which the coolant-carrying tube extends; and an enclosure having a perimeter region for engaging the substrate to form an at least partially enclosed cavity with the multiple heat generating electronics components and the multiple cold plates being disposed within the cavity defined by the substrate and the enclosure, and wherein the enclosure is configured with a plurality of bores, each bore being sized and located to at least partially receive a respective coolant-carrying tube of the plurality of coolant-carrying tubes extending from the cold plates, the enclosure further being configured with a manifold in fluid communication with the plurality of bores and the plurality of coolant-carrying tubes disposed therein for distributing coolant in parallel to at least some cold plates of the multiple cold plates via a first set of coolant-carrying tubes of the plurality of coolant-carrying tubes in fluid communication with the coolant inlets of the multiple cold plates, and for receiving coolant from at least some cold plates of the multiple cold plates via a second set of coolant-carrying tubes of the plurality of coolant-carrying tubes in fluid communication with the coolant outlets of the multiple cold plates.
