A tiered immersion cooling system includes a chassis, a cabinet frame slidably mounted to the chassis, an upper immersion tank, and a lower immersion tank. The cabinet frame is slidable between a first internal position and a first external position. Sliding motion of the cabinet frame is in a horizontal direction along a depth of the chassis. The upper immersion tank is slidably mounted to the chassis. The upper immersion tank is slidable with the cabinet frame in the horizontal direction. The upper immersion tank slides relative to the cabinet frame, in a vertical direction along a height of the chassis. The lower immersion tank is positioned below the upper immersion tank in the vertical direction. The lower immersion tank is mounted to slide independently from the cabinet frame, in the horizontal direction. The lower immersion tank slides between a second internal and a second external position.

A system is provided for collection, detection and containment of leaked liquid. The system may include a spout connected to a liquid cooling manifold for channeling liquid. The system may also include a collection tray positioned under the spout and configured to contain the liquid from the spout. The system may further include a leak detection rope having a first end coupled to the liquid cooling manifold, a middle portion extending along the spout, and a second end placed inside the collection tray for detection of liquid.

A manifold assembly provided for a server rack. The manifold assembly can include a manifold tube with a port hole within a spotface that extends inward from an external surface of the manifold tube. A channel can be included having a channel aperture. A bushing can also be included with a throughbore extending along a bushing axis. The bushing can be coupled to the channel with the bushing axis in alignment with a center of the channel aperture. The channel can be rigidly secured to the manifold tube to provide structural support thereto relative to the server rack, with the bushing captivated between the channel and the manifold tube and the bushing received within the spotface.

A liquid cooling system includes a liquid coolant conduit in proximity to heat-generating electrical components within an enclosed space. The conduit allows circulation of a liquid coolant to extract heat from the heat-generating components. The heat-generating components includes at least one first heat-generating electrical component and at least one second heat-generating electrical component. The first heat-generating component produces greater heat than the second heat-generating component. The enclosed space includes an inlet and an outlet. The conduit includes a nozzle fluidly connected to the inlet. The nozzle is located within the enclosed space. The nozzle forms first and second aperture sets. The first aperture set directs the liquid coolant to the first heat-generating component. The second aperture set directs the liquid coolant to the second heat-generating component. The nozzle allows liquid coolant to pass the first heat-generating component at a faster rate than the second heat-generating component.

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 system and a method are disclosed for a cooling bath designed to provide a sufficient and evenly distributed coolant flow throughout the bath. The cooling system includes a holding unit with a coolant distribution chamber that will distribute coolant through multiple distribution pipes beneath device chambers, promoting even distribution of coolant through the device chambers. An external pump causes coolant to be expelled from the cooling bath. The flow of coolant expelled from the cooling bath is controlled in a coolant separation chamber with a separation layer that bisects the coolant separation chamber. The separation layer is perforated with calibrated holes to slow down the speed of coolant exiting the cooling bath to prevent a funnel effect, protect the device chambers from coolant waves and coolant level fluctuation generated by the pump, and evenly distribute removal of hot coolant from the cooling bath.

A fixing device includes a main body, a sliding block, and a fixing rod. The main body has a sliding rail and a guiding hole, and the sliding rail which is disposed at a front side of the main body vertically extends. The guiding hole adjoins the sliding rail and horizontally extends through the main body. The sliding block is slidably connected to the sliding rail. The fixing rod is movably connected to the sliding block extending through the guiding hole, and the sliding block is configured to move along the sliding rail and enable the guiding hole to drive the fixing rod to horizontally move.

An immersion tank is used for cooling an electronic circuit. The immersion tank includes a tank body that stores coolant, a housing that is provided inside the tank body and that houses the electronic circuit, a moving member movably supported relative to the tank body, a supply hole which is formed in the housing and through which the coolant is supplied to an inside of the housing, an opening/closing member that is displaced from a closed position at which the opening/closing member closes the supply hole to an open position at which the opening/closing member opens the supply hole, and an operatively associated mechanism that displaces the opening/closing member in accordance with movement of the moving member.

A network element include one or more modules each supporting one or more pluggable modules; and a first manifold and a second manifold each configured to connect to a conduit associated with a coldplate, wherein one of the first manifold and the second manifold is an inlet manifold and the other is an outlet manifold for a cooling fluid that flows through the conduit to cool the one or more pluggable modules. The one or more pluggable modules can be each a pluggable optical module that is one of compliant to any of XFP, SFP, XENPAK, X2, CFP, CFP2, CFP4, CFP8, QSFP, QSFP+, QSFP28, OSFP, and QSFP-DD and have a housing that has dimensions similar to any of XFP, SFP, XENPAK, X2, CFP, CFP2, CFP4, CFP8, QSFP, QSFP+, QSFP28, OSFP, and QSFP-DD.

A liquid cooling structure for a server with low-force quickseal joints to carry the coolant includes a first support, a first joint, a second support, a second joint, a first magnet, and a second magnet. The first support is set on the cabinet body. The second support is set on the server body. The first joint is set on the first support. The second joint is arranged on the second support and can be coupled with the first joint. The first magnet is set on first support. The second magnet is set on second support. The first magnet and second magnet with opposite magnetism attract each other to reduce the amount of force required for coupling the first joint and the second joint, and is labor-saving.
