  • Publication number: 20130240196
    Abstract: A container includes a main body, a number of computer servers, a number of heat dissipating fins, a first group of fans and a second group of fans. Two frames are symmetrically mounted in the main body. The frames divide the main body to a middle airflow channel and side airflow channels. The computer servers are positioned in the frames. The heat dissipating fins are positioned on the main body. A number of flow spaces are defined between the heat dissipating fins. A first group of fans are positioned in the middle airflow channel, and a second group of fans are positioned in the side airflow channels. The first group of fans draws the airflow into the middle airflow channel to pass through the computer servers, and the second group of fans draws the airflow passing through the computer servers to the heat dissipating fins.

    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.
