Abstract: 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.

Abstract: 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.

Abstract: 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.
