Abstract
A system for removing heat from electrical systems includes a dehumidification device including a desiccant, an evaporative cooling device, air moving devices, and an air flow control devices. The air moving device moves air through the dehumidification device, the evaporative cooling device, and the electrical systems. The air flow control device controls a rate of flow through the dehumidification device.
Claims20
A data center, comprising:
- rack-mounted computing devices that include heat producing components;
- and
- a cooling system, comprising:
- one or more desiccant wheels;
- one or more evaporative cooling devices downstream from at least one of the desiccant wheels;
- and
- one or more air moving devices;
- wherein:
- at least one of the air moving devices is configured to move air through at least one of the desiccant wheels, at least one of the one or more evaporative cooling devices, and at least one of the heat producing components of the rack-mounted computing devices;
- and
- the cooling system is configured to transfer heat from the rack-mounted computing devices to at least a portion of air being moved through the at least one of the desiccant wheels to promote reactivation of the at least one of the desiccant wheels.

A system for removing heat from rack-mounted computing devices, comprising:
- one or more desiccant wheels;
- one or more evaporative cooling devices;
- and
- one or more air moving devices;
- wherein:
- at least one of the air moving devices is configured to move air through at least one of a plurality of dehumidification devices, at least of the evaporative cooling devices, and one or more of the rack-mounted computing devices;
- and
- the system is configured to transfer heat from heat producing components of the rack-mounted computing devices to at least a portion of air being moved through at least one of the desiccant wheels to promote reactivation of the at least one of the desiccant wheels.
5 more elements
A method, comprising:
- moving, via one or more air moving devices, at least one stream of air through one or more desiccant wheels to remove water vapor from the air;
- moving the at least one stream of air through one or more evaporative cooling devices downstream from at least one of the desiccant wheels;
- delivering at least a portion of the air from the one or more evaporative cooling devices to a conditioned space to remove heat from rack-mounted computing devices in the conditioned space;
- and
- transferring at least a portion of the heat from the rack-mounted computing devices to at least one of the desiccant wheels to promote reactivation of the at least one of the desiccant wheels.
