Thermochromic equipment rack
View Patent ↗A thermochromic indicator is vertically disposed on a rack. Such that the thermochromic indicator is visible from a distance. In some examples, the thermochromic indicator indicates a bulk air temperature and a gradient air temperature. The thermochromic indicator provides a real-time visual of air temperatures of computing equipment and devices housed within a computing facility. The thermochromic indicator may be vertically disposed on a front-face and/or a back-face or a rack. A plurality of thermochromic indicators may be disposed on a plurality of front-faces and/or back-faces of racks of an array of racks.

a thermochromic indicator disposed vertically along a height of the front-face of each of the plurality of racks and at least partially obstructing an airflow opening in the front face, wherein each of the thermochromic indicators indicates:
an air temperature gradation of cold air entering vertically along the height of the front-face of the respective rack on which the thermochromic indicator is disposed.
2. The system of claim 1 , wherein each of the plurality of racks has a back-face opposite the front-face, the back-face defining a hot air exit side of the array, and the system further comprising:
another thermochromic indicator disposed vertically along the back-face of each of the plurality of racks, wherein each of the other thermochromic indicators indicates:
an air temperature of hot air exiting vertically along the back-face of the respective rack on which the thermochromic indicator is disposed.
3. The system of claim 2 , wherein the front-face thermochromic indicators and the back-face thermochromic indicators of each rack comprise a thermochromic ink applied to the respective front-face and back-face subsequent to a painting of the front-face and the back-face of each rack.
4. The system of claim 2 , wherein the front-face thermochromic indicators and the back-face thermochromic indicators of each rack comprise:
a thermochromic paint applied to a base metal of the respective front-face and the back-face of each rack;
a thermochromic plastic fastened to the respective front-face and the back-face of each rack; or
a thermochromic label applied to the respective front-face and the back-face of each rack.
5. The system of claim 1 , wherein the array of the plurality of racks comprises a substantially linear array of a plurality of racks or a substantially curvilinear array of a plurality of racks.
6. The thermochromic indicator of claim 1 , wherein the airflow opening is located on a perforated door.
7. A telecommunication equipment rack comprising:
computing equipment housed in an interior of the rack;
a front-face having a vertical height; and
a thermochromic indicator disposed on and extending substantially the vertical height of the front-face and at least partially obstructing an airflow path of the front-face, wherein the front-face thermochromic indicator indicates:
an air temperature gradation of air entering the airflow path along the vertical height of the front-face of the rack on which the thermochromic indicator is disposed.
8. The rack of claim 7 , further comprising a back-face, opposite the front-face, having a vertical height; and
another thermochromic indicator disposed along the vertical height of the back-face, wherein the back-face thermochromic indicator indicates:
an air temperature of air exiting along the vertical height of the back-face of the rack on which the thermochromic indicator is disposed.
9. The rack of claim 8 , wherein the front-face thermochromic indicator and the back-face thermochromic indicator each comprise a strip of thermochromic ink applied along the vertical height of the front-face and the back-face of the rack, respectively.
10. The rack of claim 9 , wherein the front-face and the back-face each comprise a perforated door, and the strip of thermochromic ink is applied substantially proximate to a middle portion of each the perforated doors.
11. The rack of claim 8 , wherein the front-face thermochromic indicator and the back-face thermochromic indicator each comprise an array of individual marks of thermochromic ink applied along the vertical height of the front-face and the back-face, respectively.
12. The rack of claim 11 , wherein the front-face and the back-face each comprise a perforated door, and the array of individual marks of thermochromic ink are applied substantially proximate to a middle portion of each the perforated doors.
13. The rack of claim 8 , wherein the front-face thermochromic indicator and the back-face thermochromic indicator each comprise a thermochromic paint applied to the front-face and the back-face.
14. The rack of claim 13 , wherein the front-face and the back-face each comprise a rack post, and the thermochromic paint is applied to a base metal of each of the rack posts.
15. The rack of claim 13 , wherein the front-face and the back-face each comprise a perforated door, and the thermochromic paint is applied to a base metal of each the perforated doors.
16. The rack of claim 8 , wherein the front-face thermochromic indicator and back-face thermochromic indicator each comprise a thermochromic label applied to the front-face and the back-face.
17. The rack of claim 16 , wherein the front-face and the back-face each comprise a perforated door, and each of the thermochromic labels are applied proximate to a middle portion of each the perforated doors.
18. The rack of claim 8 , wherein the front-face thermochromic indicator and back-face thermochromic indicator each comprise a thermochromic plastic fastened to the front-face and the back-face.
19. A thermochromic indicator configured to be vertically disposed on a data center rack, the thermochromic indicator comprising:
a substrate material configured to be removably disposed on an airflow opening of the rack, the substrate material comprising:
a vertical height the same as a vertical height of the rack; and
a curvilinear surface arranged along the vertical height; and
a thermochromic material disposed on the curvilinear surface arranged along the vertical height to indicate multiple temperatures of air flowing into the rack along the vertical height at a same time.
20. The thermochromic indicator of claim 19 , wherein the substrate material further comprises a material thickness having a minimum depth of at least about 0.3 inches and a maximum depth of at least about 0.8 inches.
21. The thermochromic indicator of claim 19 , wherein the thermochromic material comprises a thermochromic ink, a thermochromic paint, a thermochromic paper, a thermochromic film, and/or a thermochromic label.
