  • Patent number: 11910566
    Abstract: A commonly designed processor heat exchanger decouples the mounting hardware used to mount the heat exchanger to a processor from the heat exchanger itself. This allows a single heat exchanger design to be mounted to various different types of processors using processor customized mounting brackets that engage with flanges extending out from a body of the heat exchanger.

  • Publication number: 20230417619
    Abstract: A leak detection system for a thermal interface material (TIM) includes a sensor located proximate to a processor. As thermal fluctuations or other events cause the TIM to flow out of the gap between the processor and a thermal management device, a leak detection sensor may detect the presence of the TIM. This allows an operator of the computing device to identify TIM leaks, thereby preventing or reducing damage to the processor or other electronic components of a computing device.

  • Publication number: 20230422444
    Abstract: A computing system and related methods are described. The computing system includes a heat-generating component. The computing system includes an evaporation plate thermally connected to the heat-generating component. The computing system includes a cryogenic cooling system positioned proximate to the evaporation plate. The cryogenic cooling system is configured to release a cryogenic fluid onto the evaporation plate to cool the heat-generating component. The cryogenic fluid has a boiling point of less than 273 K.

  • Publication number: 20230417609
    Abstract: An electrically conducting substrate includes a plurality of layers. A strain gauge is deposited on a layer of the plurality of layers. The strain gauge measures the stress and/or strain of the electrically conducting substrate. This allows the strain gauge to determine whether a stress or strain of the electrically conducting substrate has caused the electrically conducting substrate to deform, crack, or break.

  • Publication number: 20230418352
    Abstract: A status monitoring system includes a status sensor configured to monitor a status of an electronic circuit. If the status monitoring system detects a status that exceeds a threshold, the status monitoring system records the details of the event on the electronic circuit. The status monitoring system operates in a low-power power mode during transit from a manufacturing facility to an installation location.

  • Publication number: 20230403812
    Abstract: A rack security system includes a locking mechanism connected to a server. The locking mechanism is configured to lock onto the busbar of a rack. When the locking mechanism is locked to the busbar, the locking mechanism may prevent removal of the server from the rack. When the locking mechanism is unlocked, the server may be removable from the rack.

  • Publication number: 20230364527
    Abstract: A leak mitigation system for a fluid-cooled computing device includes an absorbent pad having a fluid sensor connected to an absorbent material. The absorbent pad is placed in a position relative to the fluid-cooled computing device to collect fluid from the cooling system. The sensor detects the presence of a fluid absorbed by the absorbent material and the leak mitigation system implements a leak mitigation protocol to prevent or reduce damage to the computing device.

  • Patent number: 11665865
    Abstract: A system and method for controlling a cooling system for an electronic datacenter component using a two-phase thermal management system with dynamic thermoelectric regulation. The system includes a thermoelectric cooler to transfer heat to a hot conduit of the thermal management system and initialize or maintain a natural convective flow of working fluid by maintaining a temperature difference between a hot and cold conduit.

  • Patent number: 11594261
    Abstract: A modular data storage tape library includes a modular frame having a form factor similar to other types of computing racks. The modular data storage tape library includes a hermetically sealed enclosure within the modular frame and a cooling portion within the modular frame. Data storage tapes, data storage drives and robotics for moving the data storage tapes are included within the hermetically sealed enclosure. A heat exchanger transfers heat from the hermetically sealed enclosure to the cooling portion outside of the sealed enclosure through a boundary of the hermetically sealed enclosure without introducing air from the data center into the hermetically sealed enclosure. Because air is neither introduced nor removed from the hermetically sealed enclosure, humidity fluctuations are minimal, if existent, and contaminants are prevented from entering the hermetically sealed enclosure, thus increasing the life spans of the data storage tapes included in the hermetically sealed enclosure.
