Abstract: A velocity cooled (VC) mobile data center (MDC) includes a volumetric container having an air intake opening providing an air intake path for exterior air to ingress into the container at a high velocity to provide a flow of cooling air that cools the heat generating IT equipment operating within the VC MDC while the MDC is mobile. An air intake damper is positioned within the air intake opening and can be selectively positioned between a fully opened position to a fully closed position. The VC MDC includes an air handling unit (AHU) configurable to operate in a standby mode or an active mode, ranging from providing minimal airflow to providing maximum airflow. The level of operation of the IT equipment and the amount of cooling provided by the AHU is controlled, based, in part, on a velocity of the VC MDC and resulting amount of cooling air being ingested.

Abstract: A Rack Information Handling System (RIHS) has more than one liquid cooled (LC) node containing heat-generating functional components, each LC node configured with a system of conduits to receive cooling liquid to regulate the ambient temperature of the node and provide cooling to the functional components inside the node by removing heat generated by the heat-generating functional components. A liquid control subsystem includes electrically-actuated control valves that selectively distribute cooling liquid to LC nodes each comprising a chassis received in a respective chassis-receiving bay of a rack. Liquid sensors detect a parameter of the liquid control subsystem. A liquid controller communicatively coupled to the electrically-actuated control valves and the liquid sensors detect a rack-level liquid event based at least in part on the parameter and communicates to any LC node that is affected by the rack-level liquid event.

Abstract: A dew point of air entering an information handling system is determined based on the temperature and humidity of the air. Also determined is a temperature of facility cooling water entering the information handling system. A condensation mitigation procedure is activated if a difference between the temperature of the facility cooling water and the dew point temperature is less than a first threshold value. The condensation mitigation procedure includes reducing a flow-rate of the facility cooling water to a liquid manifold using a valve. The liquid manifold is in thermally-conductive contact with a heat-generating component included at the information handling system.

Abstract: A Rack Information Handling System (RIHS) has a liquid cooling subsystem that provides cooling liquid to liquid cooled (LC) nodes received in chassis-receiving bays of a rack. Leak collection structures are positioned to receive cooling liquid that leaks from the liquid cooling subsystem. Liquid sensors detect a presence of leaked cooling liquid in the leak collection structures. A leak detection subsystem responds to a detected presence of liquid by providing a leak indication. In one or more embodiments, the liquid cooling subsystem has a liquid rail formed by more than one rack interconnections vertically aligned in a rear section of the rack that are connected by modular rail conduits for node-to-node fluid transfer. The leak collection structures include a pipe cover received over at least one modular rail conduit. A liquid cavity of each pipe cover spills over into another lower pipe cover at a rate that can be correlated to severity of the leak.
