Abstract: A flow-through folding membrane accumulator comprises a hollow cylindrical housing and a folding flexible membrane disposed in an interior volume of the housing. The membrane defines an interior liquid channel extending through the membrane along a longitudinal axis, and liquid coolant flows from an inlet of the accumulator through the interior liquid channel to an outlet of the accumulator. The membrane is sealed to the housing such that an air-tight cavity filled with a gas is formed between the housing and the membrane. The cavity radially surrounds the internal liquid channel, with the membrane separating the cavity and the internal liquid channel. Volumes of the cavity and channel change in response to deformation of the membrane and based on pressures of the liquid coolant. The membrane may comprise multiple folds extending parallel to the longitudinal axis and distributed circumferentially around the axis.

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.

Abstract: A process includes communicating a coolant flow between an inlet and an outlet of a coolant subsystem that is associated with a cooling domain to remove thermal energy from a plurality of processor-based nodes of the cooling domain. The communication of the coolant flow has associated predefined parameters. The process includes regulating a temperature of the coolant flow at the outlet. In accordance with example implementations, the regulation includes determining, based on the predefined parameters, a minimum collective power consumption by the processor-based nodes to maintain a temperature of the coolant flow at the outlet at or above a minimum threshold temperature, and based on the minimum power consumption, scheduling jobs to be executed by the nodes.

Abstract: Male and female fittings are configured to mate to form a valved connector system. Some embodiments of the female fitting include movable poppet configured to sealingly engage a flared projection within the female fitting. Some embodiments of the male fitting include a male mating aperture, and a movable plug configured to sealingly engage the male mating aperture. When the female fitting is mated with a male fitting, the male fitting forces the poppet to disengage from the flared projection, and the flared projection forces the plug to recede into the male fitting, to open a fluid path through the valved connector system.
