Abstract
A Rack Information Handling System (RIHS) has a liquid cooling subsystem that provides cooling liquid to liquid cooled (LC) nodes received in chassis-receiving bays of a rack. Leak collection structures are positioned to receive cooling liquid that leaks from the liquid cooling subsystem. Liquid sensors detect a presence of leaked cooling liquid in the leak collection structures. A leak detection subsystem responds to a detected presence of liquid by providing a leak indication. In one or more embodiments, the liquid cooling subsystem has a liquid rail formed by more than one rack interconnections vertically aligned in a rear section of the rack that are connected by modular rail conduits for node-to-node fluid transfer. The leak collection structures include a pipe cover received over at least one modular rail conduit. A liquid cavity of each pipe cover spills over into another lower pipe cover at a rate that can be correlated to severity of the leak.
