US Patent 10004165 Self-filling humidity control device for equipment racks

A humidification assembly includes an enclosure, for example, arranged around a component of a datacenter. A base extends through a wall of the enclosure. Inside the enclosure, the base includes a well. Outside the enclosure, the base receives a container having a total volume that includes water and air. Water may flow from the container through a passage in the base to the well, for example, until equilibrium is reached and a predetermined water level in the well is thereby maintained. Water from the well thus provides a replenishing source of water to be evaporated for humidifying the air within the enclosure.
