摘要： Apparatuses and methods are 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.

摘要： A cooling apparatus and method are provided which include an air-to-liquid heat exchanger and system coolant inlet and outlet plenums mounted to an electronics rack door along an edge of the door remote from the edge hingedly mounted to the rack. The plenums are in fluid communication with the heat exchanger and respectively include an inlet and outlet. Coolant supply and return hoses are disposed above the electronics rack and couple the inlet plenum to a coolant supply header and the outlet plenum to a coolant return header. The hoses are sufficiently long and flexible to open or close the door. A stress relief structure is attached to the top of the door and clamps the supply and return hoses in fixed relation to relieve stress on connect couplings at the ends of the hoses to the plenum inlet and outlet during opening or closing of the door.
