Abstract

Novel tools and techniques are provided for providing in-lineup passive air distribution system designs, and for delivering more effective cooling for termination dense network equipment with high heat dissipation. In some embodiments, one or more air distribution units might be positioned in-line with one or more heat generating equipment. The one or more air distribution units might receive air from an HVAC system, and might distribute the received air to the one or more heat generating equipment. In some cases, the one or more air distribution units might distribute the received air to a position in front of and/or behind the one or more heat generating equipment for intake by an air intake device of at least one of the one or more heat generating equipment. Some air distribution units might comprise dowels for storing fiber slack. Some dowels might comprise an air shaft for distributing the received air.

First claim

What is claimed is:

1 . A method, comprising:
receiving air, with an air distribution unit that is positioned in-line with one or more heat generating equipment, from a heating, ventilation, and air conditioning (“HVAC”) system; and distributing, with the air distribution unit, the received air to a position in front of the one or more heat generating equipment for intake by a first air intake device of at least one of the one or more heat generating equipment.

2 . The method of claim 1 , wherein the air distribution unit is a passive air distribution unit.

3 . The method of claim 1 , wherein the HVAC system is configured to provide heating, ventilation, and air conditioning to at least a portion of a building in which the one or more heat generating equipment is located.

4 . The method of claim 1 , wherein distributing, with the air distribution unit, the received air to the position in front of the one or more heat generating equipment comprises distributing, with the air distribution unit, the received air at a rate of at least 500 cubic feet per minute (“CFM”) to the position in front of the one or more heat generating equipment.

5 . The method of claim 1 , further comprising:
distributing, with the air distribution unit, the received air to a position to a rear portion of the one or more heat generating equipment for intake by a second air intake device of the at least one of the one or more heat generating equipment.

6 . The method of claim 1 , wherein each of at least one of the one or more heat generating equipment comprises:
one or more telecommunications equipment; a telecommunications rack containing the one or more telecommunications equipment; and a rack cooling device in communication with the first air intake device, the rack cooling device configured to distribute air within the telecommunications rack to cool the one or more telecommunications equipment.

7 . An air distribution unit, comprising:
an enclosure positioned in-line with one or more heat generating equipment; an air supply portion configured to receive air from a duct termination point of a heating, ventilation, and air conditioning (“HVAC”) system; and a plurality of air vents configured to distribute the received air to a position in front of the one or more heat generating equipment for intake by an air intake device of each of the one or more heat generating equipment.

8 . The air distribution unit of claim 7 , further comprising:
a flexible connector assembly configured to provide flexible connection between the air supply portion and the duct termination point of the HVAC system.

9 . The air distribution unit of claim 7 , wherein each of the plurality of air vents comprises adjustable louvered directional vent registers.

10 . The air distribution unit of claim 9 , wherein the adjustable louvered directional vent registers comprise motorized adjustable louvered directional vent registers.

11 . The air distribution unit of claim 7 , further comprising:
a plurality of dowels attached to one or more of a front surface or a rear surface of the air distribution unit, each of the plurality of dowels comprising a shaft and a dowel end plate, wherein the plurality of dowels are configured to store fiber slack from one or more cables from at least one of the one or more heat generating equipment, by wrapping the fiber slack from the one or more cables around at least a portion of the shaft of at least one dowel of the plurality of dowels.

12 . The air distribution unit of claim 11 , wherein each of one or more dowels of the plurality of dowels comprises an air passage through the shaft and through the dowel end plate, wherein the air passage directs air from the HVAC system through the enclosure of the air distribution unit to a position in front of the air distribution unit.

13 . The air distribution unit of claim 12 , wherein the dowel end plate of at least one dowel of the one or more dowels comprises a louvered vent opening configured to direct air from the HVAC system through the enclosure of the air distribution unit through the shaft of the at least one dowel to the position in front of the one or more heat generating equipment.

14 . The air distribution unit of claim 7 , further comprising:
one or more cable troughs affixed to one or more of a front surface or a rear surface of the air distribution unit, the one or more cable troughs configured to enable cable routing across the air distribution unit; a plurality of anchor points configured to enable floor mounting of the air distribution unit; and a plurality of guard rail covers configured to cover the plurality of anchor points.

15 . A system, comprising:
one or more heat generating equipment arranged inline within a row in a room, each of the one or more heat generating equipment comprising:
an air intake device; and
a heating, ventilation, and air conditioning (“HVAC”) system for supplying one or more of heating, ventilation, or air conditioning to the room, the HVAC system comprising:
a plurality of duct termination points;
one or more air distribution units, each air distribution unit comprising:
an enclosure positioned in-line with the one or more heat generating equipment within the row;
an air supply portion configured to receive air from a first duct termination point of the plurality of duct termination points of the HVAC system; and
a plurality of air vents configured to distribute the received air to a position in front of the one or more heat generating equipment for intake by the air intake device of each of the one or more heat generating equipment.

16 . The system of claim 15 , wherein at least one of the one or more heat generating equipment further comprises:
one or more telecommunications equipment; a telecommunications rack containing the one or more telecommunications equipment; and a rack cooling device in communication with the air intake device, the rack cooling device configured to distribute air within the telecommunications rack to cool the one or more telecommunications equipment.

17 . The system of claim 15 , wherein each of the one or more air distribution units further comprises:
a flexible connector assembly configured to provide flexible connection between the air supply portion and the first duct termination point of the HVAC system.

18 . The system of claim 15 , wherein each of the plurality of air vents of at least one air distribution unit of the one or more air distribution units comprises adjustable louvered directional vent registers.

19 . The system of claim 18 , wherein the adjustable louvered directional vent registers comprise motorized adjustable louvered directional vent registers.

20 . The system of claim 15 , wherein at least one air distribution unit of the one or more air distribution units further comprises:
a plurality of dowels attached to one or more of a front surface or a rear surface of the at least one air distribution unit, each of the plurality of dowels comprising a shaft and a dowel end plate, wherein the plurality of dowels are configured to store fiber slack from one or more cables from at least one of the one or more heat generating equipment, by wrapping the fiber slack from the one or more cables around at least a portion of the shaft of at least one dowel of the plurality of dowels.
