Cooling fluid distribution system with leakage containment and detection
A recently granted patent (Publication Number: US11778777B2) describes a cooling fluid distribution system for server chassis in data centers. The system includes a rack manifold that circulates cooling fluid to the devices in the server chassis. Connectors on the rack manifold allow for fluid connection between the devices and the rack manifold. Leakage containment panels are attached to the rack manifold on two sides of the connectors and can be moved between an idle position and an active position to manage the cooling fluid. A leakage detection sensor is also included to detect any leaks from the fluid connection between the connectors and the devices.
The cooling fluid distribution system further includes joints that allow for rotation of the leakage containment panels between the idle and active positions. In the idle position, the connectors are accessible from the side corresponding to the joints, and a containment is removed. In the active position, the leakage containment panels form a containment that limits the flow of cooling fluid to prevent it from being sprayed on other components in case of a leak.
The system also incorporates a leakage detection cable positioned with one of the leakage containment panels to detect when the cooling fluid reaches the panel. The leakage detection sensor is connected to the cable and reports any leaks to a rack management controller that manages the flow of cooling fluid in the electronic rack.
In addition, the patent describes an electronic rack that includes multiple server chassis arranged in a stack. Each server chassis has one or more cold plates associated with computing components. The cooling fluid distribution system, with its rack manifold, connectors, leakage containment panels, and leakage detection sensor, is used to circulate cooling fluid to the cold plates and detect any leaks from the fluid connection between the connectors and the server chassis.
Furthermore, the patent covers a data center system that consists of multiple electronic racks, each with server chassis and the cooling fluid distribution system. The system includes joints for adjusting the leakage containment panels and a slide mechanism to move the panels between the idle and active positions. The containment formed by the leakage containment panels in the active position prevents the cooling fluid from being sprayed on other components in case of a leak.
Overall, this patent presents a cooling fluid distribution system that effectively manages and detects leaks in server chassis in data centers, ensuring the proper circulation and containment of cooling fluid.
