  • Publication number: 20240114650
    Abstract: Targeted cooling in a liquid cooling system including detecting, for a node cooled by the liquid cooling system, a condition indicating increased heating, wherein the liquid cooling system includes a primary pump and a node-specific pump positioned in a loop of the liquid cooling system between the primary pump and the node; and responsive to detection of the condition, increasing cooling to the node by increasing liquid flow rate at the node-specific pump positioned in the loop of the liquid cooling system between the primary pump and the node, thereby achieving a higher temperature differential between an inlet and an outlet line and increased waste heat recovery.

  • Publication number: 20240114651
    Abstract: Cooling systems having a conduit and a heat transfer device for transferring heat from an electronic component are disclosed. According to an aspect, a cooling system includes a conduit configured to be in conductive heat transfer interface with an electronic component. The conduit is configured to transfer a first portion of heat from the electronic component to a flow of a cooling liquid. The heat transfer device is also configured to be in conductive heat transfer interface with the electronic component, and to transfer a second portion of heat from the electronic component. The cooling system includes a heat collector manifold configured to receive the flow of the cooling liquid with the first portion of heat from the conduit, to receive the second portion of heat via conductive heat transfer from the heat transfer device, and to transfer the second portion of heat to the flow of the cooling liquid.

  • Publication number: 20240114652
    Abstract: Cooling systems having cooling and augmentation loops for electronic components and related methods are disclosed. According to an aspect, a cooling system for an electronic component includes a cooling loop in thermal transfer interface with a first electronic component. The cooling loop is configured to contain a first flow of a cooling liquid between an inlet and an outlet. The cooling system also includes at least one augmentation loop configured to contain a second flow of the cooling liquid and alternately engage and disengage with respect to the cooling loop, such that engaging the augmentation loop to the cooling loop converts a series flow pattern with the first flow of the cooling liquid into a parallel flow pattern of a portion of the first flow of the cooling liquid with the second flow of the cooling liquid, without disconnection of the cooling loop from the inlet and outlet.

  • Patent number: 11822400
    Abstract: An apparatus for a hybrid single-phase/two-phase cooling loop to enhance cooling of components in a computing device is disclosed. The apparatus includes a single-phase cooling loop routed through a first part of a component. The component includes semiconductor devices. The single-phase cooling loop includes a fluid configured to remain in a liquid state after removing heat from the first part of the component. The apparatus includes a two-phase cooling loop routed through a second part of a component. The two-phase cooling loop includes a dielectric fluid configured to at least partially transition from a liquid state to a gas state at a selected temperature of a semiconductor device of the second part of the component while removing heat from the second part of the component.

  • Publication number: 20230314271
    Abstract: Detecting coolant leaks in a server system including receiving, by a controller in the server system with nodes stacked vertically, a voltage fault alert from a first node; receiving, by the controller in the server system with nodes stacked vertically, a voltage fault alert from a second node located below the first node; and upon receiving the voltage fault alert from the first node and the voltage fault alert from the second node, powering down, by the controller, one or more nodes located below the second node.
