Abstract: A cooling unit (500) is provided to facilitate cooling of coolant passing through a coolant loop (501). The cooling unit (500) includes one or more heat rejection units (510a, 510b) and an elevated coolant tank (520). The heat rejection unit (510a, 510b) rejects heat from coolant passing through the coolant loop (501) to air passing across the heat rejection unit (510a, 510b). The heat rejection unit (510a, 510b) includes one or more heat exchange assemblies (600) coupled to the coolant loop (501) for at least a portion of the coolant to pass through the one or more heat exchange assemblies (600). The elevated coolant tank (520), which is elevated above at least a portion of the coolant loop (501), is coupled in fluid communication with the one or more heat exchange assemblies (600) of the heat rejection unit (510a, 510b), and facilitates return of coolant to the coolant loop (501) at a substantially constant pressure.

Abstract: Methods of preventing overheating of computer equipment in a cabinet when a supply coolant to a cooler in the cabinet fails. An example embodiment is a data center that includes a plurality of cabinets and at least two coolant supply lines. The cabinets are configured to house computer equipment and the coolant supply lines provide coolant for the cabinets. Moreover, the cabinets are arranged in at least one row of adjacent cabinets such that each row of adjacent cabinets receives coolant from alternating coolant supply lines.

Abstract: Liquid-cooled electronics racks and methods of fabrication are provided wherein a liquid-based cooling apparatus facilitates cooling of electronic subsystems when docked within the electronics rack. The cooling apparatus includes a liquid-cooled cooling structure mounted to a front of the rack, and a plurality of heat transfer elements. The cooling structure is a thermally conductive material which has a coolant-carrying channel for facilitating coolant flow through the structure. Each heat transfer element couples to one or more heat-generating components of a respective electronic subsystem, physically contacts the cooling structure when that electronic subsystem is docked within the rack, and provides a thermal transport path from the heat-generating components of the electronic subsystem to the liquid-cooled cooling structure. Advantageously, electronic subsystems may be docked within or undocked from the electronics rack without affecting flow of coolant through the liquid-cooled cooling structure.

Abstract: Es wird eine Kühleinheit (500) bereitgestellt, die Kühlung eines Kühlmittels ermöglicht, das durch einen Kühlmittelkreislauf (501) hindurchfließt. Die Kühleinheit (500) weist eine oder mehrere Wärmeabführeinheiten (510a, 510b) und einen erhöht angeordneten Kühlmittelbehälter (520) auf. Die Wärmeabführeinheiten (510a, 510b) führen Wärme von dem Kühlmittel, das durch den Kühlmittelkreislauf (501) hindurchfließt, und dabei durch die Wärmeabführeinheiten (510a, 510b) hindurchfließt, an die Luft ab. Die Wärmeabführeinheit (510a, 510b) weist eine oder mehrere Wärmetauscherbaugruppen (600) auf, die mit dem Kühlmittelkreislauf (501) verbunden sind, so dass wenigstens ein Teil des Kühlmittels durch die eine oder die mehreren Wärmetauscherbaugruppen (600) hindurchfließen kann. Der erhöht angeordnete Kühlmittelbehälter (520), der über wenigstens einem Abschnitt des Kühlmittelkreislaufes (501) erhöht angeordnet ist, ist mittels Flüssigkeitsübertragung mit der einen oder den mehreren Wärmetauscherbaugruppen (600) der Wärmeabführeinheit (510a, 510b) verbunden und ermöglicht Rückführen von Kühlmittel an den Kühlmittelkreislauf (501) bei einem im Wesentlichen konstanten Druck.

Abstract: A method is provided which includes providing a multi-rack assembly having adjacent first and second electronics racks, each being at least partially air-cooled, and an air-to-liquid heat exchanger associated with the first rack for cooling at least a portion of air passing through the first rack. The heat exchanger, which is disposed at the air inlet or air outlet side of the first rack and is coupled in fluid communication with a coolant loop to receive coolant from the loop and exhaust coolant to the loop, transfers heat from air passing thereacross to coolant passing therethrough. The assembly also includes a cooling unit, associated with the first rack and cooling coolant in the coolant loop, and an airflow director associated with the second rack and facilitating ducting at least a portion of air passing through the second rack to also pass across the heat exchanger associated with the first rack.

Abstract: A method is provided for dissipating heat from a rack. The method includes: disposing a coolant-cooled heat exchanger within the rack, and providing 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.

Abstract: A cooling system such as an intra-rack cooling system 500 of a data centre comprises: one or more nodes, such as servers 300, each node having at least one temperature sensor to monitor a temperature of the node components; an air-to-liquid heat exchanger 402 configured to accept a liquid coolant input, preferably via a first shut-off valve 504, to provide cooled air to the one or more nodes; and a temperature sensor to monitor a temperature of air Tai provided by the heat exchanger. The cooling system also comprises a direct liquid cooling apparatus to provide liquid coolant to components of the one or more nodes, preferably an inlet plenum 404, i.e. manifold, and an outlet plenum 406. The apparatus supplies cold input coolant 412, preferably via a second shut-off valve 506, to the one or more nodes and ejects warm coolant 410. A valve, ideally a three-way valve 502, is configured to control a proportion of the coolant flow directed to the heat exchanger and the one or more nodes based upon the monitored temperatures. A flow rate of coolant is also controlled based upon the monitored temperatures, preferably by varying the pump strength of a pump 401.

Abstract: A cooling approach is provided for one or more subsystems of an electronics rack. The cooling approach employs a coolant distribution unit and a thermal dissipation unit. The coolant distribution unit has a first heat exchanger, a first cooling loop and a second cooling loop. The first cooling loop passes facility coolant through the first heat exchanger, and the second cooling loop provides system coolant to an electronics subsystem, and expels heat in the first heat exchanger from the subsystem to the facility coolant. The thermal dissipation unit is associated with the electronics subsystem and includes a second heat exchanger, the second cooling loop, and a third cooling loop. The second cooling loop provides system coolant to the second heat exchanger, and the third cooling loop circulates conditioned coolant within the electronics subsystem and expels heat in the second heat exchanger from the electronics subsystem to the system coolant.
