Hose barb fittings and apparatuses described herein provide increased fluid-flow rates for cooling loops used for thermal control in computer system. A hose barb fitting comprises a fluid-flow passage that extends through the hose barb fitting from a first opening to a second opening. The ratio of the cross-sectional area of the fluid-flow passage to the cross-sectional area of the hose barb fitting is between 0.4 and 0.7, inclusive. When the hose barb fitting is fully seated within a housing structure, a specialized gasket acts as both a radial seal and a face seal. Also, a flange extending from the housing structure engages with a flange extending from the hose barb fitting to prevent the hose barb fitting from being unseated.

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.

A liquid cooling distribution system can be installed to an information technology (IT) rack to deliver and distribute fluid to IT equipment. The liquid cooling system can include a fluid manifold and a container that is arranged to capture a fluid that leaks from the fluid manifold. A first fluid sensor can be arranged to detect the fluid at a first position in the container. A controller can be configured to reduce a flow of the fluid into the fluid manifold and pump out fluid from the fluid manifold, in response to the fluid in the container being detected at the first position. Further remedial measure can be taken based on various detected leak scenarios.

A flow detection device comprises a fluidic input port connected to a fluidic output port via a channel and a float located within the channel. A specific weight of the float exceeds a specific weight of a fluid injected in the flow detection device. Respective locations of the fluidic input port, of the channel and of the fluidic output port on the flow detection device cause the float to rise within the channel when a sufficient flow of the fluid is injected in the flow detection device. A sensor is provided to detect a position of the float within the channel. The flow detection device may be integrated in a cooling circuit having a cooling device for an electronic device to detect an eventual lack of a flow of a cooling fluid in the cooling circuit. A status of the flow of the cooling fluid is reported to a processor.
