Abstract

An automatically operated floor tile is disclosed for use in distributing air flow from beneath a raised floor in a computer data center. A sliding panel or control plate with holes matching those in the face of the tile is normally positioned so that the holes in the plate and the holes in the floor tile do not match up, thus preventing air flow through the tile holes. When air flow through the tile is desired a solenoid is energized to move the control plate laterally such that its holes are aligned with those in the floor tile allowing air to pass through the tile.

Automatic Opening Floor Tile for Back -up Air Cooling of Server Racks

An automatically operated floor tile is disclosed for use in distributing air flow from beneath a raised floor in a computer data center. An array of holes is provided in the face of the tile. A sliding panel or control plate with holes matching those in the face of the tile is normally positioned so that the holes in the plate and the holes in the floor tile do not match up, thus preventing air flow through the tile holes. When air flow is required a solenoid may be energized to move the control plate laterally such that its holes are aligned with those in the floor tile allowing air to pass through the tile for delivery to an adjacent computer rack. A top, front and side view of one embodiment of the invention applied to a conventional floor tile is shown in figure 1.The floor tile consists of a perforated tile on top with a cross-shaped stiffener underneath for strengthening. The plates mounted underneath the stiffener constitute the novel feature of the invention as will be discussed. Not shown in the figure is a four-sided wall slipped in between the perforated floor tile and the bottom plates to form an air plenum chamber.

Figure 1.

A detailed cross-section view of the automated floor tile is shown in figure 2. A stationary panel is attached to the stiffener. An arm with a cylindrical shaft projecting outward horizontally is rigidly attached to the underside of the stationary panel. The cylindrical shaft is comprised of three sections, two end sections made of a non-ferrous
(i.e. nonmagnetic) material and a section disposed between the two end sections made of a ferrous metal (i.e. magnetic). The control plate which is movable, is hung from the underside of the stationary panel in such manner that it can slide a small distance laterally. The amount of lateral movement allowed being such that the holes in the control plate and stationary plate may be brought into alignment. A dual coil solenoid is attached to the underside of the control plate. The cylindrical shaft extends through the dual coil solenoid such that the ferrous portion is either centrally disposed within the left
