Abstract
A data center cooling system includes a thermosiphon, an actuator coupled to the thermosiphon, and a controller. The thermosiphon includes an evaporator; a condenser; and at least one conduit coupled between the evaporator and the condenser to transport a working fluid between the evaporator and the condenser. The controller is coupled to the actuator and configured to operate the actuator to adjust a liquid level of the working fluid in the evaporator based, at least in part, on a parameter associated with a heat load of one or more data center heat generating computing devices.
Claims10
A thermosiphon cooling system for a rack-mounted device in a data center, comprising:
- an evaporator;
- a condenser fluidly coupled to the evaporator with a fluid pathway that slopes downward from the condenser to the evaporator;
- a working fluid enclosed within the evaporator, the condenser, and the fluid pathway;
- means for determining at least one parameter associated with an amount of heat generated by the rack-mounted device;
- and
- means for adjusting a liquid level of the working fluid in the evaporator based, at least in part, on the parameter associated with the amount of heat generated by the rack-mounted device.
