Abstract
A cooling system for an electronics cabinet includes a controller configured to operate at least one of a pump or a condenser of a two-phase cooling loop. The cooling system includes a high temperature mode where the setpoint is set to a high setpoint setting, and a low temperature mode where the setpoint is set to a low setpoint setting. The controller is configured to select between the high temperature mode and the low temperature mode based on an evaluation of a power outage.
Claims12
A cooling system for an electronics cabinet, comprising:
- a heat exchanger positioned to remove heat from the electronics cabinet, wherein delivery air within the electronics cabinet flows adjacent to at least one electronic component such that the delivery air removes heat from the electronic component prior to reaching the heat exchanger;
- a two-phase cooling loop configured to cool the delivery air to a setpoint, the two-phase cooling loop comprising:
- a pump configured to circulate a working fluid through a cooling loop, the heat exchanger including a portion of the cooling loop;
- and
- a condenser configured to remove heat from the working fluid in a location outside the electronics cabinet;
- and
- a controller having circuitry configured to operate at least one of the pump or the condenser of the two-phase cooling loop,
- wherein the cooling system includes a high temperature mode where the setpoint is set to a high setpoint setting,
- wherein the cooling system includes a low temperature mode where the setpoint is set to a low setpoint setting, and
- wherein the controller is configured to:
- select between the high temperature mode and the low temperature mode based on an evaluation of a power outage,
- evaluate whether the two-phase cooling loop is capable of maintaining a safe temperature level during the grid power outage in the high temperature mode, and
- adjust the two-phase cooling loop between the high temperature mode and the low temperature mode when the controller determines that the two-phase cooling loop is not capable of maintaining a safe temperature level during the grid power outage in the high temperature mode.
