Mixed-flow cooling to maintain cooling requirements

Abstract:

An apparatus that includes a plurality of heat sources; a heat sink coupled to the plurality of heat sources; a heat-exchange-fluid flow path for heat-exchange fluid to flow through such that heat is removed from the heat sink, wherein the flow path includes: a heat-exchange-fluid inlet, a first branch that includes a plurality of segments including a first and second segment, wherein each of the plurality of segments includes an upstream end and a downstream end, wherein a first portion of the heat-exchange fluid flows through the first segment in a first direction and the first portion of the heat-exchange fluid flows through the second segment in a second direction, opposite the first direction, and a second branch, wherein a second portion of the heat-exchange fluid flows through the second branch such that the second portion of the heat-exchange fluid mixes with the downstream end of the second segment.
