Abstract

A switch cabinet arrangement which includes a switch cabinet ( 1 ) with an installation frame ( 2 ) accommodated therein, which delimits an accommodation space ( 3 ) for switch cabinet fixtures and which comprises a cooling air duct ( 5, 6, 7 ), wherein the installation frame ( 2 ) comprises two parallel separated vertical profiles ( 4 ) which establish a first attachment plane (a) for the switch cabinet fixtures and wherein the cooling air duct ( 5, 6, 7 ) comprises a partition ( 5 ) which extends between the vertical profiles ( 4 ) and a respective associated switch cabinet side wall ( 12 ), characterized in that the partition ( 5 ) comprises at least one perforation ( 6 ) to which at least one air supply channel ( 7 ) is fluidically connected, which leads cooling air introduced via the perforation ( 6 ) into the air supply channel ( 7 ) in the direction of the accommodation space ( 3 ).

First claim

What is claimed is:

1. A switch cabinet arrangement comprising:
a switch cabinet with an installation frame accommodated therein, which delimits an accommodation space for switch cabinet fixtures and which comprises a cooling air duct, wherein the installation frame includes two parallel separated vertical profiles which establish a first attachment plane (a) for the switch cabinet fixtures and wherein the cooling air duct includes a partition which extends between the vertical profiles and a respective associated switch cabinet side wall, wherein the partition includes at least one perforation to which at least one air supply channel is fluidically connected, which leads cooling air introduced via the perforation into the air supply channel in the direction of the accommodation space;
the air supply channel defines a passage in fluid communication with the at least one perforation to direct cooling air through the perforation to the accommodation space, an opening of the passage is formed on a front side of the air supply channel facing away from the partition;
the air supply channel includes a first channel section through which the air supply channel is fluidically connected to the perforation, and a second channel section which has the front side with the opening of the passage; and
the second channel section is movable relative to the first channel section to allow the air supply channel to telescope in a longitudinal direction (x) that extends perpendicular to the partition.

2. The switch cabinet arrangement according to claim 1 , in which the cooling air is supplied to the accommodation space via a cooling air outlet of the air supply channel to the side and parallel relative to the attachment plane (a).

3. The switch cabinet arrangement according to claim 1 , in which at least one supply or data line is led through the air supply channel.

4. The switch cabinet arrangement according to claim 3 , in which the supply or data line is led from a switch cabinet fixture accommodated in the accommodation space, through the air supply channel and through the perforation into the partition.

5. The switch cabinet arrangement according to claim 3 , in which the air supply channel includes the passage for the introduction of a supply or data line into the interior of the air supply channel.

6. The switch cabinet arrangement according to claim 5 , in which the passage is formed in a wall section of the front side of the air supply channel, which is arranged at an angle (α) where 90°<α<180°, preferably at an angle (α) where 110°<α<150°, and particularly preferably at an angle (α) of 135° relative to the longitudinal direction (x).

7. The switch cabinet arrangement according to claim 1 , in which the switch cabinet has a cuboid rack which is formed from four vertical and eight horizontal struts, wherein the two switch cabinet side walls are flat parts connected to the rack, and wherein the partition extends between the vertical profiles of the installation frame and the respective associated flat part and is in contact with the flat part via a sealing element.

8. The switch cabinet arrangement according to claim 7 , in which the partition has a sheet metal part which is connected to one of the vertical profiles, preferably by screw connection, wherein the sealing element is put on a longitudinal edge of the sheet metal part facing the switch cabinet side wall.

9. The switch cabinet arrangement according to claim 7 , in which the sealing element is a brush strip.

10. The switch cabinet arrangement according to claim 1 , in which the installation frame is an installation frame for the 19″ switch cabinet interior construction.

11. The switch cabinet arrangement according to claim 1 , in which the vertical profile of the installation frame has, adjoining the partition, or at a fixed distance therefrom, a vertical profile side with a system perforation extending in vertical direction and consisting of regularly spaced attachment accommodations for the installation of the at least one air supply channel.

12. A switch cabinet comprising:
a rack;
an installation frame within the rack for mounting equipment within the rack, the installation frame includes two vertical profiles that are spaced apart and extend in parallel to establish a first attachment plane for the equipment;
a partition arranged between the two vertical profiles;
a perforation defined by the partition;
an air supply channel fluidically connected to the perforation;
a passage defined by the air supply channel through which cooling air can pass and enter the switch cabinet through the perforation, an opening of the passage is formed on a front side of the air supply channel facing away from the partition;
wherein:
the air supply channel includes a first channel section through which the air supply channel is fluidically connected to the perforation, and a second channel section including the front side and the opening of the passage;
the second channel section is movable relative to the first channel section to allow the air supply channel to telescope in a longitudinal direction (x) that extends perpendicular to the partition.
