Abstract:
An air-to-coolant heat exchanger for an electronics rack is provided, which includes first and second tube segments, one or more connector segments, and a plurality of thermally conductive fins attached to the tube segments. The first tube segment includes a first inner tube positioned within a first outer tube, defining a first inner coolant-carrying channel and first outer coolant-carrying channel, and the second tube segment has a second inner tube positioned within a second outer tube, defining a second inner coolant-carrying channel and second outer coolant-carrying channel. The connector segment(s) couples in fluid communication at least one of the first and second inner coolant-carrying channels, or the first and second outer coolant-carrying channels. The heat exchanger is coupled to separately receive a first coolant and a second coolant, with the first coolant passing through the inner channels, and the second coolant through the outer channels.
