Abstract: Example implementations relate to a leak mitigation (LM) system. The LM system may include a collection tank, a first valve unit coupled to the collection tank, a second valve unit coupled to a cooling loop carrying a coolant, and an LM pump coupled between the first valve unit and the second valve unit. Moreover, the leak mitigation system may also include a controller operatively coupled to the first valve unit, the second valve unit, and the LM pump to operate, in an event of a leak of the coolant from the cooling loop, the first valve unit, the second valve unit, and the LM pump to transfer at least a portion of the coolant to the collection tank from the cooling loop via the second valve unit and the first valve unit.

Abstract: A leak mitigation system for a cooling system may include an isolation valve, a controller, and a computer-readable medium. The isolation valve may selectively isolate an expansion tank from a closed loop containing a coolant circulated by a primary pump having a pump inlet. The expansion tank may maintain the coolant at a predetermined pressure at the pump inlet in the closed loop. The controller may communicate with the primary pump and the isolation valve. The computer-readable storage medium may include instructions executable by the controller to: in response to a detection of a leak of the coolant from the closed loop, shut down the primary pump; and close the isolation valve to isolate the expansion tank from the closed loop.

Abstract: A cooling apparatus includes a plurality of containers and a plurality of connectors. Each connector connects adjacent containers of the plurality of containers. The cooling apparatus is installable in a computing device such that each electronic component to be cooled in the computing device is interposed between adjacent containers. Each container may include a body, an inlet, and an outlet. The body may include first and second ends and may define a chamber through which a coolant is to flow. The body may be expandable responsive to pressure from the coolant and deformable responsive to contacting one of the electronic components so as to conform to a profile of the electronic component. The inlet may be disposed at the first end of the body through which the coolant enters the chamber. The outlet may be disposed at the second end of the body through which the coolant exits the chamber.

Abstract: Example implementations relate to a leak mitigation system for a cooling system in a computing infrastructure. The leak mitigation system may include tank that is pre-pressurized, a valve unit fluidly coupled to the tank and a cooling loop, and controller operatively coupled to the valve unit. The cooling loop comprises one or more tubes to facilitate a flow of a coolant to cool one or more computing devices. The controller may detect a leak of the coolant from the cooling loop, and in response to detection of the leak of the coolant, the controller may operate the valve unit to establish a fluid coupling between the tank and the cooling loop to transfer at least a portion of the coolant away from the cooling loop.
