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.

Systems and methods for thermal management of electronic devices

A system for thermal management of a computing device includes an immersion chamber, a cooling fluid, a plurality of heat-generating components, and a means for removing vapor from a cooling volume of the cooling fluid. The cooling fluid is positioned in the immersion chamber and fills at least a portion of the immersion chamber. The plurality of heat-generating components is positioned in the cooling fluid and arranged in a series. The series defines the cooling volume of the cooling fluid contacting the plurality of heat-generating components to cool the plurality of heat-generating components.

A thermal management system for cooling electronic devices includes an immersion cooling system, a vapor buffer tank, and a liquid buffer tank. The immersion cooling system includes an immersion tank defining an immersion chamber, a working fluid in the immersion chamber, and a condenser. A liquid portion of the working fluid defines an immersion bath in the immersion chamber and a vapor portion defines a headspace above the immersion bath in the immersion chamber. The condenser condenses the vapor portion of the working fluid to the liquid portion of the working fluid. The vapor buffer tank is in fluid communication with the headspace, and a vapor valve selectively allows fluid communication between the vapor buffer tank and the headspace. The liquid buffer tank is in fluid communication with the immersion chamber, and a liquid valve selectively allows fluid communication between the liquid buffer tank and the immersion chamber.

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.

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.
