Leak mitigation system for a cooling system

A cooling system for a computing device, comprising:

• a closed loop configured to transfer thermal energy from the computing device to a coolant circulating though the closed loop, the closed loop comprising
• a primary pump having a pump inlet, the primary pump configured to circulate the coolant through the closed loop;
• an expansion tank to maintain the coolant at a predetermined pressure at the pump inlet when the expansion tank is fluidly coupled to the pump inlet;
• a heat exchanger to remove thermal energy from the closed loop;
• and
• an isolation valve to selectively isolate the expansion tank from the closed loop;
• a controller communicatively coupled to the primary pump and the isolation valve;
• and
• a computer-readable storage medium comprising instructions executable by the controller to, in response to a detection of a leak of the coolant from the closed loop:
• shut down the primary pump;
• and
• close the isolation valve to isolate the expansion tank from the closed loop.

A method for mitigating a leak in a cooling system having a closed loop, the method comprising:

• detecting a leak of coolant from the closed loop;
• shutting down a primary pump operable to circulate the coolant through the closed loop, the primary pump having a pump inlet;
• and
• closing an isolation valve to isolate an expansion tank from the closed loop, the expansion tank to maintain the coolant at a predetermined pressure at the pump inlet in the closed loop when the expansion tank is fluidly coupled to the pump inlet.
