Abstract
A method is presented for adjusting coolant flow resistance through one or more liquid-cooled electronics racks. Flow restrictors are employed in association with multiple heat exchange tube sections of a heat exchange assembly, or in association with a plurality of coolant supply lines or coolant return lines feeding multiple heat exchange assemblies. Flow restrictors associated with respective heat exchange tube sections (or respective heat exchange assemblies) are disposed at the coolant channel inlet or coolant channel outlet of the tube sections (or of the heat exchange assemblies). These flow restrictors tailor coolant flow resistance through the heat exchange tube sections or through the heat exchange assemblies to enhance overall heat transfer within the tube sections or across heat exchange assemblies by tailoring coolant flow. In one embodiment, the flow restrictors tailor a coolant flow distribution differential across multiple heat exchange tube sections or across multiple heat exchange assemblies.
