  • Publication number: 20240314977
    Abstract: A thermal management device includes a body, a fluid movement structure, and a movement mechanism. The body is configured to receive heat from a heat-generating component at a proximal surface, and the fluid movement structure is on a distal surface of the body that is distal to the proximal surface, wherein the fluid movement structure is configured to direct fluid flow of a working fluid and the body is configured to transfer heat to the working fluid. The movement mechanism is configured to move the fluid movement structure relative to the body.

  • Publication number: 20240268069
    Abstract: An immersion cooling system includes an immersion tank that is configured to retain dielectric working fluid and to hold a plurality of computing devices submerged in the dielectric working fluid. The immersion cooling system also includes a condenser that is configured to cause condensation of vaporized working fluid. The immersion cooling system also includes a subcooling heat exchanger that is in fluid communication with a coolant source. The coolant source provides coolant having a coolant temperature that is lower than a boiling point of the dielectric working fluid. The subcooling heat exchanger is positioned so that heat transfer can occur between the dielectric working fluid and the subcooling heat exchanger. The immersion cooling system also includes a control system that controls how much of the coolant flows into the subcooling heat exchanger based at least in part on a temperature of the dielectric working fluid.

  • Publication number: 20240260232
    Abstract: The discussion relates to cooling computing devices and specifically to managing two-phase cooling. One example can include a two-phase liquid immersion tank containing heat generating components and a liquid phase of a coolant having a boiling point within an operating temperature range of the heat generating components. The example can also include a stratification chamber fluidly coupled to the liquid immersion tank and configured to at least partially separate a gas phase of the coolant from other gases. The example can further include a condenser chamber fluidly coupled to the stratification chamber and configured to receive the gas phase of the coolant and cause the gas phase of the coolant to phase change back into the liquid phase of the coolant.

  • Publication number: 20240147663
    Abstract: A liquid-submersible thermal management system includes a cylindrical outer shell and an inner shell positioned in an interior volume of the outer shell. The cylindrical outer shell has a longitudinal axis oriented vertically relative to a direction of gravity, and the inner shell defines an immersion chamber. The liquid-submersible thermal management system a spine positioned inside the immersion chamber and oriented at least partially in a direction of the longitudinal axis with a heat-generating component located in the immersion chamber. A working fluid is positioned in the immersion chamber and at least partially surrounding the heat-generating component. The working fluid receives heat from the heat-generating component.

  • Publication number: 20240130091
    Abstract: Techniques for mitigating loss of vaporized working fluid in a two-phase immersion cooling system may be implemented using one or more supplemental condensers that facilitate condensation of vaporized working fluid when the immersion tank is open, and one or more vapor collection points that are in fluid communication with at least one supplemental condenser. One or more fluid displacement devices may be configured to create suction pressure at the one or more vapor collection points. One or more vents may be positioned in the door. The one or more vents may be configured to permit movement of air from outside the immersion tank into an interior portion of the immersion tank without permitting loss of vaporized working fluid. A directional blowing device may be configured to blow a gaseous substance against a computing device in a downward direction as the computing device is being pulled upward out of the immersion tank.

  • Patent number: 11956930
    Abstract: A liquid-submersible thermal management system includes a shell, a heat-generating component, a working fluid, and at least one heat-dispersing element. The shell defines an immersion chamber where the heat-generating component is located in the immersion chamber. The working fluid is positioned in the immersion chamber and at least partially surrounds the heat-generating component so the working fluid receives heat from the heat-generating component. The at least one heat-dispersing element is positioned on exterior surface of the shell to conduct heat from the shell into the heat-dispersing element.
