Abstract: Example implementations relate to a cooling module, and a method of cooling an electronic circuit module. The cooling module includes first and second cooling components fluidically connected to each other. The first cooling component includes a first fluid channel having supply, return, and body sections, and a second fluid channel. The second cooling component includes an intermediate fluid channel. The body section is bifurcated into first and second body sections, and the first and second body sections are further merged into a third body section. The supply section is connected to the first and second body sections. The return section is connected to the third body section and the intermediate fluid channel via an inlet fluid-flow path established between the first and second cooling components. The second fluid channel is connected to the intermediate fluid channel via an outlet fluid-flow path established between the first and second cooling components.

Abstract: An example device includes processing circuitry and a memory. The memory includes instructions that cause the device to perform various functions. The functions include receiving datastreams from a plurality of sensors of a high performance computing system, classifying each datastream of the each sensor to one of a plurality of datastream models, selecting an anomaly detection algorithm from a plurality of anomaly detection algorithms for each datastream, determining parameters of the each anomaly detection algorithm, determining an anomaly threshold for each datastream, and generating an indication that the sensor associated with the datastream is acting anomalously.

Abstract: Methods and systems for creating cold plates are disclosed. For example, in one example method for manufacturing a cold plate made of a thermally-conductive plastic includes performing a first injection-molding process using the thermally-conductive plastic to produce a first unitary body, the first unitary body including one or more elongated sections forming a unitary body, performing a second injection-molding process using the thermally-conductive plastic to produce a second unitary body, the second unitary body incorporating the first unitary body so as to cover a majority of the first unitary body and form a respective coolant pipe body corresponding to each elongated section, and performing a machining process on the second unitary body so as to create a conduit in each respective coolant pipe body suitable for a fluid to pass through to create respective coolant pipes.

Abstract: Hose barb fittings and apparatuses described herein provide increased fluid-flow rates for cooling loops used for thermal control in computer system. A hose barb fitting comprises a fluid-flow passage that extends through the hose barb fitting from a first opening to a second opening. The ratio of the cross-sectional area of the fluid-flow passage to the cross-sectional area of the hose barb fitting is between 0.4 and 0.7, inclusive. When the hose barb fitting is fully seated within a housing structure, a specialized gasket acts as both a radial seal and a face seal. Also, a flange extending from the housing structure engages with a flange extending from the hose barb fitting to prevent the hose barb fitting from being unseated.

Abstract: A pump includes an armature, a rotor assembly, a liquid path connector and a member. The armature includes a ferromagnetic core, a winding and a through passageway. The rotor assembly is disposed in the passageway and includes an impeller to rotate to pump liquid through the passageway. The liquid path connector is connected to the armature to communicate the liquid with the passageway. The member contacts an outer surface of the armature and contacts an outer surface of the liquid path connector to transfer thermal energy from the armature to the liquid path connector.

Abstract: An axial flow pump comprises a housing having a bore, a cylindrical permanent magnet within the housing bore, and at least one impeller inside the permanent magnet and adapted to cause fluid to flow within the cylindrical permanent magnet. The permanent magnet is configured to rotate in the bore around its longitudinal axis. A motor lamination stack surrounds the cylindrical permanent magnet. The motor lamination stack is formed substantially as a cuboid, extending in a width and height direction perpendicular to the axis of rotation of the cylindrical permanent magnet. The diameter of the bore is at least 80% of the dimension of the cuboid in the height direction. A coil of the motor lamination is configured to be energized and to create a rotating magnetic field in the lamination stack to rotate the cylindrical permanent magnet around its longitudinal axis. The coil is disposed to one or both sides of the pump.

Abstract: Example implementations relate to an optical biofilm probe. For example, in an implementation, the optical biofilm probe may include a light source to project light towards a substrate disposed within a bypass and a detector to detect light from the substrate. Properties of light detected by the detector may be affected by biofilm formation on the substrate. The bypass may be connected in parallel to a conduit of a fluid system.
