  • Patent number: 11212942
    Abstract: A cooling arrangement for autonomous cooling of a rack hosting components and fans comprises a closed loop and an open loop. Liquid cooling is used in the closed loop to transfer heat from heat-generating units of the components to a primary side of a liquid-to-liquid heat exchanger. An air-to-liquid cooling unit is used in the open loop to absorb heat expelled from the rack by the fans. A liquid from a cold supply line is first heated to some degree in the air-to-liquid cooling unit before reaching a secondary side of the liquid-to-liquid heat exchanger. The primary side being hotter than the secondary side, heat is transferred from the primary side to the secondary side of the liquid-to-liquid heat exchanger. The liquid is expelled at a higher temperature from the secondary side to a hot return line.

The controller also selects a first PWM algorithm from the plurality of PWM algorithms based at least in part on the harmonic signature associated with the first PWM algorithm mitigating the one or more resonance frequencies associated with the refrigeration system. The controller further operates the electronic power converter according to the first PWM algorithm.

  • Patent number: 10701838
    Abstract: A self-installing connector for a liquid cooling system of a datacenter component rack system. A datacenter component rack may include manifolds for conveying coolant to or from one or more datacenter electronic components for liquid cooling components of the datacenter electronic component. The self-installing connector provides a fluid connection between the manifold and a liquid cooling system of a datacenter electronic component. The self-installing connector may puncture the manifold at the time the datacenter electronic component is installed. The self-installing connector may form an opening in the manifold and secure one end of the self-installing connector into the opening upon installation of the datacenter electronic component into the datacenter component rack. The self-installing connector can separate at a dripless quick-disconnect coupling for datacenter electronic component maintenance.

  • Patent number: 10660239
    Abstract: A cooling system is provided which includes, for instance, a coolant circulation loop, one or more primary coolant pumps, and a fill and drain pump. The primary coolant pump(s) is coupled to facilitate circulating coolant through the coolant circulation loop, and the fill and drain pump facilitates selective filling of the cooling system with the coolant, or draining of the coolant from the cooling system. The fill and drain pump is integrated with the cooling system as a backup coolant pump to the primary coolant pump(s), and circulates the coolant through the coolant circulation loop responsive to an error in the primary coolant pump(s). The primary coolant pump(s) and fill and drain pumps may be different types of pumps, and the cooling system further includes a control system for automatically activating the fill and drain pump upon detection of an error in the primary coolant pump(s).

  • Patent number: 10624237
    Abstract: A two-phase liquid immersion cooling system is described in which heat generating computer components cause a dielectric fluid in its liquid phase to vaporize. The dielectric vapor is then condensed back into a liquid phase and used to cool the computer components. Using a pressure controlled vessel and pressure controller, the disclosed system may be operated at less than ambient pressure. By controlling the pressure at which the system operates, the user may influence the temperature at which the dielectric fluid vaporizes and thereby achieve increased performance from a given computer component. Utilizing robotic arms and slot-in computing components, a self-healing computing system may be created.

  • Patent number: 10533809
    Abstract: Illustrative embodiments disclosed herein pertain to a cooling apparatus that includes a distributor plate and a conduit assembly. The conduit assembly allows a cooling fluid to flow downwards through a first set of holes in the distributor plate and onto a hot object placed below the distributor plate. The cooling fluid then flows upwards from the hot object into a second set of holes in the distributor plate. The first set of holes are shaped to offer a pressure increase to the cooling fluid flowing towards the hot object. The second set of holes are shaped to offer reduced resistance to the cooling fluid flowing away from the hot object. The distributor plate and the conduit assembly are fabricated from a material that is a heat insulator thereby preventing heat transfer from the cooling fluid flowing away from the hot object to the cooling fluid flowing towards the hot object.
