Systems and methods for controlling leaks in liquid cooling systems for computer devices

A method for controlling liquid cooling system leaks in a server rack including a plurality of servers, the method comprising:

• monitoring a plurality of leak detection sensors each positioned at a corresponding one of the plurality of servers below a section of a liquid conveyance system;
• determining if a signal was received from one of the plurality of leak detection sensors indicative of a leak in the liquid conveyance system;
• in response to determining a received signal is indicative of a leak, determining the leak detection sensor and the corresponding one of the plurality of servers associated the received signal;
• in response to determining the corresponding one of the plurality of servers associated with the received signal, disconnecting power to the corresponding one of the plurality of servers;
• and
• in response to determining the corresponding one of the plurality of servers associated with the received signal, transmitting one or more signals to implement moving a first valve and a second valve from open positions to closed positions,
• wherein the first valve is positioned within the liquid conveyance system between a hot rack manifold and a thermal contact structure associated with the one of the plurality of servers associated with the received signal, and wherein the second valve is positioned within the liquid conveyance system between a cool rack manifold and the thermal contact structure, thereby limiting movement of cooling liquid along the fluid conveyance system from hot rack manifold and the cool rack manifold.

A rack system, comprising:

• a plurality of computing devices;
• and
• a liquid cooling system including:
• a plurality of leak detection sensors each positioned at a corresponding one of the plurality of computing device below a section of a liquid conveyance system,
• a first valve positioned within the liquid conveyance system between a hot rack manifold and a thermal contact structure associated with one of the plurality of computing devices,
• a second valve positioned within the liquid conveyance system between a cool rack manifold and the thermal contact structure, and
• a controller connected to the plurality of liquid leak detection sensors, the first valve, and the second valve, the controller is configured to:
• monitor the plurality of leak detection sensors,
• determining if a signal was received from one of the plurality of leak detection sensors indicative of a leak in the liquid conveyance system,
• in response to determining a received signal is indicative of a leak, determining the leak detection sensor and the corresponding one of the plurality of computing devices associated the received signal,
• in response to determining the corresponding one of the plurality of computing devices associated with the received signal, transmitting a signal to disconnect power to the corresponding one of the plurality of computing devices, and
• in response to determining the corresponding one of the plurality of computing devices associated with the received signal, transmitting one or more signals to implement moving the first valve and the second valve from open positions to closed positions.
