Patent number: 11937406Abstract: A system provides cooling to an infrastructure having heat-generating units. Internal cooling units are thermally connected to the heat-generating units. An external cooling unit dissipates thermal energy of a heat-transfer fluid circulating in the internal cooling units. A cooling circuit connects the internal and external cooling units. A pump maintains a flow of the heat-transfer fluid for transferring thermal energy from the heat generating units to the external cooling unit. A reservoir thermally connected to the cooling circuit contains a phase change material (PCM) changing between solid and liquid states according to a temperature of the heat-transfer fluid. Thermal energy is transferred between the cooling circuit and the PCM depending on whether a temperature of the heat-transfer fluid is above or below a phase-change temperature value of the PCM. A supplemental cooling device thermally connected to the reservoir dissipates heat from the reservoir to the atmosphere.Type: GrantFiled: June 10, 2022Date of Patent: March 19, 2024Assignee: OVHInventors: Ali Chehade, Hadrien Bauduin

Patent number: 11516943Abstract: The present disclosure is directed to a direct liquid cooling system for cooling of electronic components and configured to maintain a predetermined thermostable environment for the electronic components. The system includes a reservoir and a rack removably placed in the reservoir and securely containing electronic components to be cooled. The system also includes a dielectric coolant which is configured to flow upward in parallel streams between the electronic components and a pump that facilitates continuous pumping of the dielectric coolant thereby forcing the dielectric coolant upwards through the electronic components and overflowing the dielectric coolant within the reservoir. A heat exchanger is also provided and coupled with the reservoir via an outlet pipeline. Additionally, a controller is provided to monitor the temperature of the dielectric coolant and adjust the flow of the coolant.Type: GrantFiled: December 28, 2017Date of Patent: November 29, 2022Assignee: INPRO TECHNOLOGIES LIMITED LIABILITY COMPANYInventors: Alexey Petrovich Bilan, Viktor Yurievich Zhilko, Viktor Mikhailovich Kaufman, Alexander Nikolaevich Nikitin

Patent number: 11445631Abstract: An electronic rack includes an array of server blades arranged in a stack. Each server blade contains one or more servers and each server includes one or more processors to provide data processing services. The electronic rack includes a coolant distribution unit (CDU) and a rack management unit (RMU). The CDU supplies cooling liquid to the processors and receives the cooling liquid carrying heat from the processors. The CDU includes a liquid pump to pump the cooling liquid. The RMU is configured to manage the operations of the components within the electronic rack such as CDU, etc. The RMU includes control logic to determine an optimal pump speed and an optimal processor clock rate based on a first relationship between cost of the electronic rack and clock rate of the processors and a second relationship between energy consumption of the electronic rack, clock rate of the processors and pump speed.Type: GrantFiled: March 19, 2020Date of Patent: September 13, 2022Assignee: BAIDU USA LLCInventors: Shuai Shao, Tianyi Gao
