Abstract
An information handling system may include an information handling resource, a liquid cooling system for providing cooling of the information handling resource, a leak detection system for detecting a leak of fluid from the liquid cooling system, and a breaker valve fluidically coupled to the liquid cooling system and communicatively coupled to the leak detection system and configured to, in response to a stimulus from the leak detection system indicating presence of a leak of fluid from the liquid cooling system, automatically transition from an open state in which the breaker valve permits flow of fluid through the breaker valve to a closed state in which the breaker valve impedes flow of fluid through the breaker valve.
Claims21
An information handling system comprising:
- an information handling resource;
- a liquid cooling system for providing cooling of the information handling resource;
- a leak detection system for detecting a leak of fluid from the liquid cooling system;
- and
- a breaker valve fluidically coupled to the liquid cooling system and communicatively coupled to the leak detection system and configured to, in response to a stimulus from the leak detection system indicating presence of a leak of fluid from the liquid cooling system, automatically transition from an open state in which the breaker valve permits flow of fluid through the breaker valve to a closed state in which the breaker valve impedes flow of fluid through the breaker valve.
A breaker valve configured to be fluidically coupled to a liquid cooling system and communicatively coupled to a leak detection system for detecting a leak of fluid from the liquid cooling system and further configured to, in response to a stimulus from the leak detection system indicating presence of a leak of fluid from the liquid cooling system, automatically transition from an open state in which the breaker valve permits flow of fluid through the breaker valve to a closed state in which the breaker valve impedes flow of fluid through the breaker valve.
The breaker valve of claim 9, further comprising a spring mechanically coupled to the body and the throw and arranged such that the throw is mechanically biased in the closed position.
The breaker valve of claim 10, further comprising a solenoid having a movable core configured to mechanically engage with a mechanical feature of the throw in order to overcome the spring force of the spring and maintain the throw in the open position in an absence of the stimulus.
A method, in a breaker valve configured to be fluidically coupled to a liquid cooling system and communicatively coupled to a leak detection system for detecting a leak of fluid from the liquid cooling system, the method comprising:
- in response to a stimulus from the leak detection system indicating presence of a leak of fluid from the liquid cooling system, automatically transitioning from an open state in which the breaker valve permits flow of fluid through the breaker valve to a closed state in which the breaker valve impedes flow of fluid through the breaker valve.
