Abstract: A system for cooling an electronic component includes a cylindrical container, a support, a heat exchanger, and one or more micropumps. The cylindrical container includes an internal volume that stores dielectric liquid. The internal volume is formed by an interior wall and a bottom of the cylindrical container. The support is positioned in the internal volume of the cylindrical container, and retains the electronic component within the dielectric liquid stored in the internal volume of the cylindrical container. The support also controls a flow of the dielectric liquid. The heat exchanger is positioned in the cylindrical container and circulates water from an external environment of the cylindrical container into and out of the internal volume of the cylindrical container. The one or more micropumps are integrally formed with and powered by the electronic component, and circulate the dielectric liquid through the electronic component.

Abstract: A system for immersion cooling electronic components includes a cylindrical container having a circular cross section, a cooling element disposed in the cylindrical container and containing a first cooling fluid, and a volume of a second cooling fluid disposed in the cylindrical container and in contact with the cooling element for exchange of heat between the second cooling fluid and the first cooling fluid, the second cooling fluid comprising an immersion cooling fluid. A heat generating electronic component is disposed within the cylindrical container and at least partially immersed in the second cooling fluid for exchange of heat between the electronic component and the second cooling fluid, and a fluid circulating device is disposed in the second cooling fluid to direct a flow of the second cooling fluid through the electronic component and over the cooling element.

Abstract: In a method of data filing, a data filing system receives a data element to be included in a data file. The data filing system randomly assigns an encryption key (703) to the data element so as to avoid that the encryption key (703) is assigned to another data element in the data filing system. The data filing system defines an expiry date (702) for the data element and internally stores the encryption key (703) in association with the expiry date (702) that has been defined. The data filing system encrypts the data element on the basis of the encryption key (703) so as to obtain an encrypted data element. The data filing system includes the encrypted data element in the data file. The data filing system deletes (705) the encryption key (703) when the expiry date (702) associated with the encryption key is reached. This technique allows respecting a right to be forgotten while ensuring integrity of an audit trial within the data filing system.

Abstract: A system for immersion cooling computing system equipment includes a container containing a volume of immersion cooling fluid. At least one heat generating computing system equipment component and a liquid-liquid heat exchanger are disposed in the volume of immersion cooling fluid. A manifold system is disposed between the heat generating computing system equipment component and the liquid-liquid heat exchanger to direct a flow of immersion cooling fluid between the heat generating computing system component and the liquid-liquid heat exchanger and to isolate the flow of immersion cooling fluid from a bulk amount of immersion cooling fluid. The flow of immersion cooling fluid and the bulk amount of immersion cooling fluid constitutes the volume of immersion cooling fluid.
