    摘要： A cooling apparatus and method are provided for cooling an electronic subsystem of an electronics rack. The cooling apparatus includes a local cooling station, which has a liquid-to-air heat exchanger and ducting for directing a cooling airflow across the heat exchanger. A cooling subsystem is associated with the electronic subsystem of the rack, and includes either a housing facilitating immersion cooling of electronic components of the electronic subsystem, or one or more liquid-cooled structures providing conductive cooling to the electronic components of the electronic subsystem. A coolant loop couples the cooling subsystem to the liquid-to-air heat exchanger of the local cooling station. In operation, heat is transferred via circulating coolant from the electronic subsystem and rejected in the liquid-to-air heat exchanger of the local cooling station to the cooling airflow passing across the liquid-to-air heat exchanger. In one embodiment, the cooling airflow is outdoor air.

    摘要： An apparatus for facilitating servicing of a liquid-cooled electronics rack is provided. The apparatus includes a coolant tank, a coolant pump in fluid communication with the coolant tank, multiple parallel-connected coolant supply lines coupling the coolant pump to a coolant supply port of the apparatus, and a coolant return port and a coolant return line coupled between the coolant return port and the coolant tank. Each coolant supply line includes a coolant control valve for selectively controlling flow of coolant therethrough pumped by the coolant pump from the coolant tank. At least one coolant supply line includes at least one filter, and one coolant supply line is a bypass line with no filter. When operational, the apparatus facilitates filling of coolant into a cooling system of a liquid-cooled electronics rack by allowing for selective filtering of coolant inserted into the cooling system.

    摘要： A heat sink, and cooled electronic structure and cooled electronic apparatus utilizing the heat sink, are provided. The heat sink is fabricated of a thermally conductive structure which includes one or more coolant-carrying channels and one or more vapor-condensing channels. A membrane is disposed between the coolant-carrying channel(s) and the vapor-condensing channel(s). The membrane includes at least one vapor-permeable region, at least a portion of which overlies a portion of the coolant-carrying channel(s) and facilitates removal of vapor from the coolant-carrying channel(s) to the vapor-condensing channel(s). The heat sink further includes one or more coolant inlets coupled to provide a first liquid coolant flow to the coolant-carrying channel(s), and a second liquid coolant flow to condense vapor within the vapor-condensing channel(s).

    摘要： Apparatuses and methods are provided for facilitating cooling of an electronic component. The apparatus includes a vapor-compression refrigeration system, which includes an expansion component, an evaporator, a compressor and a condenser coupled in fluid communication. The evaporator is coupled to and cools the electronic component. The apparatus further includes a contaminant separator coupled in fluid communication with the refrigerant flow path. The separator includes a refrigerant cold filter and a thermoelectric array. At least a portion of refrigerant passing through the refrigerant flow path passes through the cold filter, and the thermoelectric array provides cooling to the cold filter to cool refrigerant passing through the filter. By cooling refrigerant passing through the filter, contaminants solidify from the refrigerant, and are deposited in the cold filter. The separator may further include a refrigerant hot filter coupled to a hot side of the thermoelectric array for further filtering the refrigerant.

    摘要： A cooling apparatus and method are provided. The cooling apparatus includes a coolant-cooled heat exchanger for facilitating dissipation of heat generated within an electronics rack, and a coolant control apparatus. The coolant control apparatus includes at least one coolant recirculation conduit coupled in fluid communication between a facility coolant supply and return, wherein the facility coolant supply and return facilitate providing facility coolant to the heat exchanger. The control apparatus further includes a coolant pump(s) associated with the recirculation conduit(s) and a controller which monitors a temperature of facility coolant supplied to the heat exchanger, and redirects facility coolant, via the coolant recirculation conduit(s) and coolant pump(s), from the facility coolant return to the facility coolant supply to, at least in part, ensure that facility coolant supplied to the heat exchanger remains above a dew point temperature.
