Air curtain containment system and assembly for data centers
An air curtain containment system and assembly for data centers forms an air curtain over the server cabinets thereby separating hot air in a hot aisle from cool ambient air. The air curtain containment system includes ducts which include a hot air intake section that receives hot air discharged from servers, which are disposed in server cabinets. The ducts include heat exchangers for cooling the hot air and at least one air curtain discharge section. A housing is coupled to a wall of the ducts, and includes a cooling edge device fan. The cooling edge device fan is disposed along the ducts, and is configured to draw the hot air for cooling through the heat exchangers. An air curtain fan assembly is disposed along the ducts. The air curtain fan assembly expels cold air through the air curtain discharge section, and thereby forms an air curtain over the server cabinets.

4 . The air curtain containment system of claim 1 , wherein the at least one heat exchanger is positioned over the air intake section.
5 . The air curtain containment system of claim 1 , wherein the at least one housing further includes at least one cool air exhaust section to expel the cold air to ambience.
6 . The air curtain containment system of claim 5 , wherein the at least one cool air exhaust section is implemented as a window covered by a safety wire.
7 . The air curtain containment system of claim 1 , wherein the at least one housing is a cylindrical shape or a conical shape.
8 . The air curtain containment system of claim 1 , wherein the at least one air curtain fan assembly includes:
a pipe including at least one opening along a length of the pipe; and
fans disposed on each side of the enclosure defining the plenum, wherein the fans include:
inlets configured to draw in a portion of the cold air flowing from the heat exchanger; and
outlets configured to discharge the cold air into the pipe,
wherein the pipe extends between the fans, and
wherein the at least one opening of the pipe directs the cold air out of the at least one opening, and forms the air curtain above the server cabinets.
9 . The air curtain containment system of claim 8 , wherein the at least one opening is a slit extending along a portion of the pipe, at least one slit, at least one nozzle, or at least one circular aperture.
10 . The air curtain containment system of claim 1 , wherein the air curtain is configured to create a barrier between a hot aisle and a cold aisle.
11 . The air curtain containment system of claim 1 , wherein the heat exchanger includes rows coupled together in a counter-flow configuration.
12 . The air curtain containment system of claim 1 , wherein at least one server cabinet of the server cabinets has a different height than other server cabinets of the server cabinets.
13 . An air curtain containment assembly comprising:
at least one heat exchanger for cooling heated air in a hot aisle formed by IT racks;
first fans in fluid communication with the at least one heat exchanger and configured to draw the heated air through the at least one heat exchanger;
an enclosure forming a volume between the at least one heat exchanger and the first fans;
at least one air distribution duct disposed adjacent to the enclosure; and
second fans configured to draw cooled air cooled by the at least one heat exchanger from the volume into the at least one air distribution duct, wherein the at least one air distribution duct is configured to form the cooled air into an air curtain extending to at least a portion of the IT racks.
14 . The air curtain containment assembly of claim 13 , wherein the second fans are coupled to the at least one air distribution duct,
wherein each fan of the second fans includes:
an inlet configured to draw in a portion of cold air flowing from the at least one heat exchanger; and
an outlet configured to discharge the cold air into the at least one air distribution duct,
wherein the at least one air distribution duct extends between the second fans, and
wherein the at least one air distribution duct includes at least one opening along a portion of the air distribution duct for directing the cold air out of the at least one opening and forming the air curtain extending to the IT racks.
15 . The air curtain containment assembly of claim 14 , wherein the at least one opening is a slit extending along at least one of a length of the at least one air distribution duct, at least one slit, at least one nozzle, or at least one circular aperture.
16 . The air curtain containment assembly of claim 13 , wherein the air curtain is configured to create a barrier between the hot aisle and a cold aisle.
17 . The air curtain containment assembly of claim 13 , wherein the at least one heat exchanger includes rows coupled together in a counter-flow configuration.
18 . The air curtain containment assembly of claim 13 , wherein the second fans are disposed on the enclosure.
19 . An air curtain containment system comprising:
at least one heat exchanger for cooling heated air generated by IT racks;
at least one first fan configured to draw the heated air through the at least one heat exchanger to cool the heated air, yielding cooled air;
at least one air distribution duct disposed near the IT racks; and
at least one second fan configured to draw air cooled by the at least one heat exchanger into the at least one air distribution duct, wherein the at least one air distribution duct is configured to form the cooled air into an air curtain to separate the heated air generated by the IT racks from cool ambient air.
20 . The air curtain containment system of claim 19 , further comprising an enclosure forming an at least partially enclosed volume between the at least one heat exchanger and the at least one first fan.
