An example axial pump for delivering liquid coolant to cool an electronic device comprises a conduit defining a flow path from an inlet of the conduit to an outlet of the conduit and an impeller in the conduit. The impeller is rotatable about an axis of rotation parallel to the flow path. The pump also has a motor stator configured to drive rotation of the impeller body about the axis of rotation. In addition, the pump comprises an adjustment mechanism coupling the impeller to the conduit. The adjustment mechanism is actuatable to cause translation of the impeller relative to the conduit. This may allow for adjustment of a clearance between a blade tip of a blade of the impeller and a wall of the conduit.

Auxiliary module includes attachment elements, cooling component, and auxiliary PCA having a circuit board, an electrical connector, and electronic components. The attachment elements are configured to attach the auxiliary module to supporting arms protruding from the PCA such that the electrical connector is coupled to a complementary electrical connector of the PCA, and the attachment elements extend through apertures in the supporting arms. The cooling component is attached to the auxiliary PCA and includes a first portion thermally coupled to cooling conduit in an installed state of the auxiliary module and a second portion thermally coupled to the electronic components in an attached state of the cooling component to the auxiliary PCA. In an attached state of the auxiliary module to the supporting arms and a coupled state of the electrical connector with the complementary electrical connector, the auxiliary module is movable along multiple directions relative to the supporting arms.

Example implementations relate to a chassis cooling resource. In some examples, a chassis cooling resource includes a controller, comprising instructions to detect a failure corresponding to a first cooling system of a first chassis coupled to a server rack, and alter settings of a second cooling system of a second chassis coupled the server rack to provide additional cooling resources to the first cooling system in response to the detected failure.

A circuit board cooling apparatus is disclosed having a heat spreader device to be thermally coupled with a surface of the circuit board to be cooled. Also, a conforming heat transfer device is disclosed that is thermally and physically coupled with the heat spreader device to conform to a surface contour of the heat spreader device on a first side of the heat transfer device. The cooling apparatus also includes a heat transport device physically attached and thermally coupled with a second side of the heat transfer device.

One aspect described in this application provides an apparatus that includes an external tray hose with an integrated booster pump for cooling a computing device. The booster pump can boost fluid flow and fluid pressure of coolant fluid pumped toward the computing device on a server tray. The booster pump includes a stator mounted around a booster pump housing with a bore. The stator includes one or more C-shaped lamination stacks for supporting coil windings. Energized coil windings generate a varying magnetic field for rotating an impeller within a housing bore to pump fluid along the housing bore of the booster pump. The apparatus includes a monitor module to monitor a set of sensors to obtain information about one or more of fluid temperature, fluid pressure, and device temperature; and a control module to adjust performance of the booster pump based on the information obtained from the set of sensors.

A heat removal apparatus may comprise a vapor chamber device and a cover coupled to the vapor chamber device. The vapor chamber device comprises a base, a folded fin structure coupled to the base, with the base and folded fin structure defining a vapor chamber containing a wick and a working fluid. The cover and the vapor chamber device define a liquid chamber configured to receive liquid coolant. The folded fin structure comprises a plurality of folded fins defining a first plurality of grooves on a first side of the folded fin structure and defining a second plurality of grooves on a second side of the folded fin structure. The first plurality of grooves are part of the vapor chamber. The second plurality of grooves are part of the liquid chamber.

A pair of fluid couplings for liquid cooling electronic devices comprises a first fluid coupling and second fluid coupling. The first fluid coupling comprises a female coupling interface and the second fluid coupling comprises a male coupling interface to couple with the female coupling interface. Each of the fluid couplings comprises a magnetic latch assembly coupled to the coupling interface thereof. Each magnetic latch assembly comprises a shell, magnets housed within the shell, and a group of ramp-and-hook latches coupled to the shell. The magnets cause the magnetic latch assemblies to magnetically attract one another during coupling, reducing the force a user may need to apply to complete the coupling. The ramp-and-hook latches of one magnetic latch assembly are complementary to the ramp-and-hook latches of the other magnetic latch assembly, and they are arranged to engage with one another and interlock when the first and second fluid couplings are coupled.

Fluid couplings with magnetic latch assembly

Example implementations relate to an electronic system providing thermal management of a removable device when connected to a host device of the electronic system including a receptacle, and a heat transfer device having first and second portions. The host device has a cooling component. The removable device having a heat spreader, is detachably coupled to the host device. The receptacle having spring fingers, is coupled to one of the cooling component or the heat spreader. The first portion is coupled to one of the cooling component or the heat spreader, and the second portion is protruded outwards. When the removable device is connected to the host device, the second portion extends through the receptacle such that the spring fingers establish direct thermal interface with the second portion to allow waste-heat to transfer between the heat transfer device and one of the cooling component or the heat spreader via the receptacle.

In the examples provided herein, a system includes an electrochemical sensor having two electrodes inserted in a fluid to be tested, where an alternative current (AC) voltage is applied across the two electrodes; an electrochemical sensor having two electrodes inserted in a fluid to be tested, wherein an alternative current (AC) voltage across the two electrodes; and a frequency response analyzer to analyze the measured the electrical response across multiple frequencies. The system also includes a memory to store a baseline of the electrical response across multiple frequencies, and a processor to determine from the stored baseline and the measured electrical response whether the electrical response is outside a predetermined range.

A system chassis may comprise a frame having a width, depth, and height and a plurality of divider walls coupled to the frame and forming a plurality of receptacles each configured to receive an electronics tray containing an electronic assembly. Each of the plurality of divider walls comprises a metal sheet having a front edge, a back edge, and two lateral edges, the two lateral edges attached to two lateral walls of the frame. The front edge of the metal sheet has a concave shape such that a distance between the front edge and the back edge of the metal sheet continuously decreases while moving laterally from one lateral edge to a center of the front edge and continuously increases while moving laterally from the center to the opposite lateral edge.

Switch sub-chassis systems and methods for rack-scale servers are disclosed. A switch sub-chassis is arranged for modular installation in an enclosure and includes structural support features that allow multiple hot-serviceable line-cards and an integrated high-density optical fiber connectivity within the sub-chassis. Various features of the switch sub-chassis and associated line-cards allow liquid-electro-optical blindmate of the line-cards so that the line-cards are serviceable, allow high-density and complex fiber shuffle assemblies support, and facilitate ease of installation and/or servicing of fiber assemblies.
