Cold plate with high-aspect ratio micro- or nano-tubes, and associated methods and systems

Abstract

A cooling system has a cooling loop for cooling one or more heat-generating components. A pump circulates a coolant through the cooling loop. An internally cooled cold plate defines a major surface and a plurality of microtubes extending from an open first end to an opposed open second end. The plurality of microtubes is fluidically coupled with the pump. The internally cooled cold plate is configured to transfer heat received through the major surface to the coolant as the coolant passes through the plurality of microtubes. The plurality of microtubes can provide a ratio of exposed surface area available for heat transfer to volume (SA/V) greater than about 200 m−1. The plurality of microtubes can extend through one or more of an alloy of copper, an alloy of aluminum, and a thermally conductive composite. A heat radiator rejects heat from the coolant to another medium.
