Abstract

A vent tile includes at least one louver, an actuator configured to control the at least one louver, a thermal imaging sensor configured to monitor temperature of a remotely located apparatus through thermal imaging of a surface of the apparatus, and a controller configured to control the actuator based upon the monitored temperature.

Claims

1. A vent tile comprising:

a casing;

at least one louver positioned within the casing;

an actuator to control the at least one louver;

a thermal imaging sensor to capture an infrared image of a surface of a remotely located apparatus to detect a temperature of the surface;

a controller to determine whether the detected temperature of the surface of the remotely located apparatus is within a predetermined temperature range and to control the actuator to vary the position of the at least one louver in response to the detected temperature of the surface of the remotely located apparatus being outside of the predetermined temperature range to vary the flow of fluid through the casing, wherein the thermal imaging sensor and the controller are housed within the casing; and

wherein the orientation of the thermal imaging sensor is variable to enable a field of view of the thermal imaging sensor to be modified.

2. The vent tile according to claim 1, wherein the thermal imaging sensor and the controller are attached to the casing.

3. The vent tile according to claim 1, wherein the vent tile is to be placed in an opening of a raised floor of a data center.

4. The vent tile according to claim 1, further comprising:

an output module to enable the controller to communicate at least one of the detected temperature and a position of the at least one louver to at least one other vent tile controller.

5. The vent tile according to claim 1, further comprising:

an output module to enable the controller to communicate at least one of the detected temperature and a position of the at least one louver to a central controller to control an air conditioning apparatus that is to supply fluid to the vent tile.

6. The vent tile according to claim 1, wherein a field of view of the thermal imaging sensor comprises a multi-pixel section on the surface of the remotely located apparatus.

7. A vent tile array comprising a plurality of vent tiles according to claim 1, wherein each of the controllers of the plurality of vent tiles is to communicate with at least one other controller of the plurality of vent tiles and wherein the controllers are to control respective actuators based upon information communicated from the at least one other controller.

8. The vent tile array according to claim 7, wherein each of the plurality of controllers communicates by one of a wireless communication and an infrared signal to the at least one other controller.

9. A method for managing fluid flow distribution comprising:

providing a vent tile having a casing with at least one louver, an actuator to control the at least one louver, a thermal imaging sensor to detect a temperature of a surface of a remotely located apparatus through thermal infrared imaging of the surface, wherein the thermal imaging sensor and the controller are housed within the casing, said method comprising;

capturing an infrared image of the surface to detect a temperature of the surface of the remotely located apparatus with the thermal imaging sensor;

determining whether the detected temperature is within a predetermined temperature range in response to a signal by the controller;

adjusting a position of the at least one louver by the actuator to vary fluid flow through the vent tile in response to the detected temperature being outside of the predetermined temperature range; and

variably orienting the thermal imaging sensor to modify a field of view of the thermal imaging sensor.

10. The method according to claim 9, wherein determining whether the detected temperature is within a predetermined temperature range further comprises determining whether the detected temperature exceeds an upper bound of the predetermined temperature range, and wherein adjusting the position of the at least one louver further comprises adjusting the position of the at least one louver to increase fluid flow through the vent tile in response to the detected temperature exceeding the upper bound of the predetermined temperature range.

11. The method according to claim 9, wherein determining whether the detected temperature is within a predetermined temperature range further comprises determining whether the detected temperature falls below a lower bound of the predetermined temperature range, and wherein adjusting the position of the at least one louver further comprises adjusting the position of the at least one louver to decrease fluid flow through the vent tile in response to the detected temperature falling below the lower bound of the predetermined temperature range.

12. The method according to claim 9, further comprising:

communicating at least one of the detected temperature and the position of the at least one louver to a controller of at least one other vent tile.

13. The method according to claim 9, further comprising:

communicating at least one of the detected temperature and the position of the at least one louver to a central controller configured to control an air conditioning apparatus that is configured to supply fluid to the vent tile.
