Abstract: An adapter for coupling a liquid cooling loop subassembly of a computing system to a device rack manifold includes a main body, a first connector disposed on the main body, a second connector disposed on the main body, and a flow control device disposed between the first and second connectors. The first connector couples the adapter to a coupling of the liquid cooling loop subassembly. The second connector couples the adapter to the device rack manifold. The flow control device may be configured to regulate a flow rate of liquid coolant through the liquid cooling loop subassembly. The adapter may be further incorporated into a rack assembly or multi-rack assembly to achieve thermal management of multiple computing systems with cooling loop subassemblies.

Abstract: An assembly includes a printed circuit board (“PCB”). An aperture extends through the PCB. The assembly also includes an array of pins and a processor package. The array of pins extends around a perimeter of the aperture, and the processor package extends over the aperture. The processor package is pressed against the array of pins by a compressive force couple.

Abstract: A planar fin for use in a heat sink includes turbulent structures extending from the sides of the planar fin. Each turbulent structure defines a longitudinal axis and having a first edge that is parallel to the longitudinal axis and connected to a planar surface of the fin. Each turbulent structure also includes a second edge opposite the first edged and in free space. The second edge defines a periphery that varies in distance from the first edge along the length of the longitudinal axis. The periphery of each second edge is further shaped such that turbulent flow of a fluid is induced in the flow flowing over the second edge at at least a predefined flow rate.

Abstract: Shrouding a disc to attenuate excitation energy of windage created by rotating the disc, with a shroud defining an edge-wise gap between the shroud and the disc, and the shroud further defining surface-wise gaps between the shroud and opposing disc surfaces, wherein the surface-wise gaps are characterized by opposing parallel surfaces having protuberant features depending therefrom toward each other that define minimum clearances with the disc surfaces.

Abstract: An apparatus and associated method is provided for injecting a processing fluid in a device that operably rotates a disc stack. A fluid injector has a nozzle defining an outlet sized to longitudinally span the disc stack to operably direct the processing fluid toward the disc stack. The nozzle also has a flow rate feature that operably directs a first flow rate of the processing fluid from the nozzle into a space adjacent a storage surface of a first disc of the disc stack and that directs a substantially different second flow rate of the processing fluid from the nozzle into another space adjacent a storage surface of a second disc of the disc stack.

A method for managing fluid flow created by a rotating disc that is operably disposed adjacent to an actuator, comprising diverting an upstream portion of the fluid flow, with respect to the actuator, away from the actuator; and diverting a downstream portion of the fluid flow, with respect to the actuator, away from a disc edge.

Abstract: An actuator assembly is provided comprising a data transfer head moved by an actuator arm in a data storing and retrieving relationship with a data storage medium. Streamwise arranged aerodynamic fluid re-directing and drag-reducing features on a surface of the actuator arm modify frictional forces acting on the arm from a fluid flow created by moving the medium. A method is provided for improving nonrepeatable runnout disturbances in a data storage device by aligning the drag-reducing features of the actuator assembly with a direction of a mean flow direction of the fluid at an outer diameter of the storage medium to divert the fluid flow away from the head gimbal assembly.
