AI summary

An adapter for coupling a liquid cooling loop subassembly of a computing system to a device rack manifold includes a main body, a first connector disposed on the main body, a second connector disposed on the main body, and a flow control device disposed between the first and second connectors. The first connector couples the adapter to a coupling of the liquid cooling loop subassembly. The second connector couples the adapter to the device rack manifold. The flow control device may be configured to regulate a flow rate of liquid coolant through the liquid cooling loop subassembly. The adapter may be further incorporated into a rack assembly or multi-rack assembly to achieve thermal management of multiple computing systems with cooling loop subassemblies.
