Abstract
In one or more embodiments, a liquid cooling system may include one or more air-assist modules (AAMs) for reducing the amount of liquid coolant needed to cool information handling systems immersed in the coolant. A controller communicatively coupled to a coolant pump, an inflation pump, a deflation valve and a coolant level sensor may determine when to add liquid coolant as well as when to increase or decrease the amount of air in the one or more air-assist modules based on the level of liquid coolant and a temperature of the coolant.
Claims20
An air-assist cooling system for a liquid cooling system comprising a tank, a plurality of rails for mounting a plurality of information handling systems, a coolant pump for introducing a liquid coolant to immerse the plurality of information handling systems in the coolant and a coolant level sensor, the air-assist cooling system comprising:
- one or more air-assist modules (AAM) s mounted on a set of the plurality of rails;
- an inflation pump for introducing air into an AAM of the one or more AAMs;
- and
- a controller executing instructions to:
- communicate with the coolant level sensor to monitor a level of the coolant in the tank;
- and
- communicate with one or more of the coolant pump and the inflation pump to adjust an amount of the coolant in the tank.
A cooling system for cooling a plurality of information handling systems, the cooling system comprising:
- a tank;
- a plurality of rails for mounting a plurality of information handling systems;
- a coolant pump for introducing a liquid coolant to immerse the plurality of information handling systems in the coolant;
- a coolant level sensor for detecting a level of the coolant in the tank;
- one or more air-assist modules (AAM) s mounted on a set of the plurality of rails;
- an inflation pump for introducing air into an AAM of the one or more AAMs;
- and
- a controller executing instructions to:
- communicate with the coolant level sensor to monitor a level of the coolant in the tank;
- and
- communicate with one or more of the coolant pump and the inflation pump to adjust an amount of the coolant in the tank.
A method of cooling information handling systems, the method comprising:
- coupling an information handling system to a server rail of a plurality of server rails in a tank;
- coupling one or more air-assist modules (AAMs) to one or more rails of the plurality of rails;
- operating a coolant pump to introduce a liquid coolant into the tank;
- determining a level of the coolant in the tank;
- positioning an inflation pump relative to the one or more AAMs;
- determining, by a controller communicatively coupled to a coolant level sensor, a level of the coolant in the tank;
- and
- performing one or more of operating the coolant pump to pump the coolant into the tank, operating the inflation pump to displace at least a portion of the coolant from the AAM, and operating a deflation valve to remove at least a portion of the air from the AAM.
