A cooling system configured to remove heat from a chimney of a server cabinet. The system includes a first heat exchanger unit in the chimney of the server cabinet. The first heat exchanger has a fluid inlet for receiving a working fluid and a fluid outlet for discharging the working fluid. The first heat exchanger also has an upstream surface receiving waste heat generated by one or more servers and a downstream surface that discharges air cooled by the first heat exchanger. The upstream surface is generally perpendicular to the downstream surface.

A cooling system (100) has a housing (101), a heat exchanger (110) and an air distribution controller (120). The housing (101) including an inlet (102) for receiving air exhausted from the server module and an outlet (103) for providing air to the server module. The heat exchanger (110) is mounted between the inlet (102) and the outlet (103), the heat exchanger (110) is configured that a refrigerant (111) contained in the heat exchanger (110) exchanges heat with air passing through the heat exchanger (110). The heat exchanger (110) accepts variation of the refrigerant liquid level. The air distribution controller (120) is mounted in an inlet side of the heat exchanger (110). The air distribution controller (120) has a movable plate which allows an airflow profile from the inlet to the heat exchanger (110) redirected. The air distribution controller (120) controls the airflow profile depending on the liquid level.

The unit further includes a diverter assembly arranged between the first pumping assembly and the heat exchanger and configured to switch between a first state in which the first fluid is directed through the heat exchanger before reaching the first outlet port and a second state in which the first fluid is directly directed to the first outlet port.

A data center configured to be positioned in an environment (e.g., an open space) has a plurality of modules. Among other things, each module has a housing forming an interior configured to contain a plurality of processing devices that generate heat during operation. To manage the temperature within the interior, each module has an air inlet configured to receive air from the environment, and an air outlet configured to exhaust air from the housing. At least three of the modules are spaced apart to form at least one lateral space between adjacent modules. The plurality of modules preferably are arranged so that the at least three modules form an interior region configured to receive the exhaust air of the at least three modules.

A heat exchanger has a structure in which a heat exchanger main body through which coolant flows is obliquely installed in a box-shaped enclosure, the heat exchanger main body is constituted by a header pipe and a plurality of heat transfer pipes connected to the header pipe and disposed at predetermined intervals along a surface of a part of the header pipe, the header pipe has an area adjacent to an inner surface of the enclosure, and a seal section is provided between the inner surface of the enclosure and the area of the header pipe adjacent to the enclosure.

Provided is a rack, comprising: a plurality of rack units; and a plurality of lockers each housing a different respective subset of the rack units, wherein respective lockers among the plurality comprise: a first respective barrier disposed between a respective pair of the rack units; a second respective barrier disposed between another respective pair of the rack units; a third respective barrier that is orthogonal to the first barrier and the second barrier, the third respective barrier being moveably or removeably coupled to the rack; a respective volume configured to receive one or more computing devices; and a respective lock configured to secure the third respective barrier to the rack in the closed position when in a locked state.

Systems and methods for cooling in a datacenter are disclosed. In at least one embodiment, a thermal load bank (TLB) system to test a hybrid datacenter cooling system includes one or more thermal features to generate heat within a TLB system and includes one or more hybrid cooling features to provide air and liquid cooling responses to such heat generated by one or more thermal features.

Technologies for allocating resources of managed nodes to workloads to balance multiple resource allocation objectives include an orchestrator server to receive resource allocation objective data indicative of multiple resource allocation objectives to be satisfied. The orchestrator server is additionally to determine an initial assignment of a set of workloads among the managed nodes and receive telemetry data from the managed nodes. The orchestrator server is further to determine, as a function of the telemetry data and the resource allocation objective data, an adjustment to the assignment of the workloads to increase an achievement of at least one of the resource allocation objectives without decreasing an achievement of another of the resource allocation objectives, and apply the adjustments to the assignments of the workloads among the managed nodes as the workloads are performed. Other embodiments are also described and claimed.

A roof system including a frame, a plurality of roof panels, wherein each roof panel is connected to the frame and is rotatable with respect to the frame, and a holding mechanism for holding a first roof panel among the plurality of roof panels in a closed position, wherein each roof panel among the plurality of roof panels overlaps at least one adjacent roof panel among the plurality of roof panels, and wherein release of the holding mechanism causes each of the roof panels to rotate toward an open position in a sequential manner.

An air flow distribution system for cooling server racks includes at least one server rack partially defining a hot aisle and a cold aisle, a first air foil disposed above the server rack, and a second air foil disposed above the first air foil. The first air foil and the second air foil are configured to receive air from the hot aisle, and to form turbulent wake patterns in the cold aisle partially defined by the server rack.
