Hybrid multi-function rack door designs are disclosed. A rack includes a housing cabinet and rack door. The housing supports a plurality of servers or information technology (IT) equipment. The rack door is coupled to the housing and includes a rack manifold and a heat exchanger. The rack manifold supplies a cooling liquid to the rack door and extracts a cooling liquid from the rack door. The heat exchanger cools air from the blade servers, and the rack manifold is integrated into the heat exchanger as part of the rack door. The rack door can have the rack manifold in a fixed position and the heat exchanged configured to pivot away from the rack manifold in an open or partially open position. The rack door can be designed as one part of the data center cooling infrastructure, and commissioned together.

A leak mitigation system for a cooling system may include an isolation valve, a controller, and a computer-readable medium. The isolation valve may selectively isolate an expansion tank from a closed loop containing a coolant circulated by a primary pump having a pump inlet. The expansion tank may maintain the coolant at a predetermined pressure at the pump inlet in the closed loop. The controller may communicate with the primary pump and the isolation valve. The computer-readable storage medium may include instructions executable by the controller to: in response to a detection of a leak of the coolant from the closed loop, shut down the primary pump; and close the isolation valve to isolate the expansion tank from the closed loop.

An example computing device includes one or more bays to receive a pluggable module, and a cold plate assembly. The cold plate assembly includes one or more cold plates to engage with the pluggable modules and transfer heat from the modules to liquid coolant. The cold plate assembly also includes a pivoting support that supports the cold plate(s) and pivots relative to the system board, and an engagement mechanism comprising a mechanical linkage with mechanical advantage attached to the pivoting support such that moving a link of the mechanical linkage causes the pivoting support to pivot between an engaged position and a disengaged position. In the engaged position, the cold plate contacts is positioned to engaged with the pluggable module, while in the disengaged position the cold plate is disengaged from the pluggable module.

A cooling system for data centre, which data centre includes a plurality of servers associated to form a rack, each server being provided with one or more heat generating means. The system includes a plurality of first heat exchange circuits and second thermosyphon circuits. The overall configuration of the system being such that the second thermosyphon circuits are in fluid communication with each other according to a parallel connection.

A cabinet liquid cooling system is configured to dissipate heat of a cabinet. A flow allocation unit is installed on a single side of the cabinet, is located in space between a side wall of the cabinet and a mounting bar of the cabinet, and is provided with a liquid inlet and a liquid outlet. A liquid cooling system (LCS) control unit is installed at the bottom of the cabinet and cyclically supplies liquid to the flow allocation unit using the liquid inlet and the liquid outlet. A liquid supply branch includes a liquid delivery pipe and a liquid return pipe. A node pipe includes a liquid inlet pipe and a liquid outlet pipe. Both the liquid inlet pipe and the liquid outlet pipe are connected to the corresponding liquid delivery pipe and liquid return pipe using the quick male connector and the quick female connector.

In some examples, a receiving bay includes a first heat transfer member that is moveable along a first axis, and a retainer to restrict movement of the first heat transfer member along a second axis different from the first axis. The first heat transfer member is to contact a second heat transfer member of a device when inserted in the receiving bay, the first heat transfer member moveable along the first axis by the contact with the second heat transfer member as the device is inserted in the receiving bay.

A coolant interface includes a line replaceable unit (LRU) inserted into a slot within a modular assembly such as a chassis for an electronics assembly. Quick disconnect fluid coupling fittings on the LRU mate with counterpart fittings on a fluid distribution manifold within the chassis when the LRU is inserted into the slot. A seal surrounding the quick disconnect fluid coupling fittings on a flat surface abutting a counterpart surface on the fluid distribution manifold when the LRU is inserted into the slot compresses the seal against the counterpart surface. Alignment pin(s) projecting from the flat surface and received by corresponding guide holes within the counterpart surface, and captive hardware provides pressure between the flat surface and the counterpart surface to increase and maintain compression of the seal. The alignment pins and captive hardware are arranged to increase mechanical stability of the connection.

An example computing device includes one or more bays to receive a pluggable module, and a cold plate assembly. The cold plate assembly includes one or more cold plates to engage with the pluggable modules and transfer heat from the modules to liquid coolant. The cold plate assembly also includes a pivoting support that supports the cold plate(s) and pivots relative to the system board, and an engagement mechanism comprising a mechanical linkage with mechanical advantage attached to the pivoting support such that moving a link of the mechanical linkage causes the pivoting support to pivot between an engaged position and a disengaged position. In the engaged position, the cold plate contacts is positioned to engaged with the pluggable module, while in the disengaged position the cold plate is disengaged from the pluggable module.

A device including a rack; an enclosure provided inside the rack; a module provided inside the enclosure; a main pipe provided in the rack; a branching tube connected to the main pipe; a cooling unit that cools a heat-generating component mounted on the module; a first connection tube that connects the branching tube with the cooling unit; and a plurality of module connection portions that are provided inside the enclosure and to which the module is connected; wherein the enclosure can slide in a state in which the module is connected to the module connection portion, and the cooling unit and the branching tube are connected by the first connection tube.

An information processing apparatus includes a plurality of electronic apparatus stacked over a plurality of hierarchies in the information processing apparatus, a heat exchanger that cools refrigerant liquid for cooling the plurality of electronic apparatus, a first distributor that distributes the refrigerant liquid from the heat exchanger to the plurality of hierarchies, a plurality of second distributor that stores the refrigerant liquid temporarily, and a plurality of pipes that branched from the distribution pipes to the plurality of the electronic apparatus, wherein the number of the second distributor increases toward a hierarchy on downstream side, the pipes of the last hierarchy are coupled to the electronic apparatus.
