The present disclosure relates to a detection system for detecting a failure in a fluid path of a fluid system, the detection system including: at least one conduit including a conduit wall which defines a fluid path for the transfer of fluid; at least one connector connected to the at least one conduit, the at least one connector including two parts, respectively a female connector and a male connector, which are fixed together in a removable manner, the male connector being rigidly joined to the female connector in a connected state of the at least one connector, and the male connector being separated at least partially from the female connector in a partially or totally disconnected state of the at least one connector; at least one electrically conductive element forming an electrical signal pathway for an electrical signal that indicates a state of the at least one conduit and/or of the at least one connector; and an electrical terminal connected electrically to the at least one electrically conductive element, such that the first electrical signal is transmitted to the electrical terminal via the electrical signal pathway.

An apparatus for providing leakage monitoring comprises an inner conduit configured to conduct a fluid therethrough. An outer conduit is coaxially located with the inner conduit and surrounds the inner conduit. The inner conduit and the outer conduit define a dielectric gap therebetween. A capacitive value defined between the inner conduit and the outer conduit defines a first capacitive value when the inner conduit is not leaking the fluid into the dielectric gap between the inner conduit and the outer conduit and defines a second capacitive value when the inner conduit is leaking the fluid into the dielectric gap between the inner conduit and the outer conduit.

The present disclosure relates to heat dissipation apparatuses. In an example, a node includes a structural module, a circuit board, a liquid pipe, and a liquid leakage monitoring apparatus. The circuit board is securely mounted on the structural module, and an electronic component including a chip is disposed on the circuit board. The liquid pipe is disposed on the circuit board, and is configured to dissipate heat for the electronic component on the circuit board. The liquid leakage monitoring apparatus includes a drainage pipe sleeved outside the liquid pipe. There is a specific gap between the drainage pipe and the liquid pipe. In response to at least that leakage occurs in the liquid pipe, leaked coolant flows in the drainage pipe.

A piping assembly includes a tube having a first end and a second end, a first leak-detection wire and a second leak-detection wire that are embedded within the tube during a molding process, a resistor electrically connected between first ends of the leak-detection wires, and a monitoring device electrically connected to second ends of the leak-detection wires to monitor a resistance of a leak detection circuit formed by first leak-detection wire, the resistor, and the second leak-detection wire.

A piping assembly includes a tube having a first end and a second end, a first leak-detection wire and a second leak-detection wire that are embedded within the tube during a molding process and are electrically isolated from one another during normal operations, and a monitoring device that is electrically connected to first ends of the leak-detection wires to form an open circuit and is configured to monitor the open circuit for a change from an open state to a closed state. The open circuit changes to the closed state when a rupture occurs in the tube and liquids create a conductive path, forming a closed circuit through the first leak-detection wire, the second leak-detection wire, the monitoring device and the liquids.

A liquid leakage detection device includes an isolation layer configured to warp around a pipe. A thin-film detection circuit is disposed on the isolation layer. The thin-film detection circuit includes at least one detection electrode loop. The isolation layer defines openings at positions corresponding to the at least one detection electrode loop. Whether a leakage occurs can be determined by obtaining a change in the resistance value of the detection electrode loop. Multiple liquid leakage detection devices can be connected in series and wrapped around a plurality of segments of a single pipe, or multiple liquid leakage detection devices can be connected in series and wrapped around multiple independent pipes one by one, thereby realizing liquid leakage detection of multiple pipe segments and directly locating the location of the leaky pipe in the event of a liquid leakage in the pipe, reducing the time and cost of liquid leakage detection.

A flexible pipe for conveying liquid hydrogen. The flexible pipe includes a multilayer wall having an inner layer, an outer layer, and a plurality of insulating layers between the inner layer and the outer layer. The inner layer is a hydrogen barrier layer and defines a flow passage for conveying liquid hydrogen. The outer layer forms an exterior of the pipe. The outer layer includes a plurality of reinforcing fiber tows.
