In order to achieve simple connection options for other coolant lines, the distribution device is configured as a main distribution unit installed in the region of the base and extends with at least one pipe between two vertical delimitation planes of the base, which are located parallel to each other at a distance, and the pipe has at least one branch part for the connection of the cooling device.
1. Field of the Invention
This invention relates to a switchgear cabinet or rack having a base situated under the usable space and having a distribution device with a coolant line for a cooling medium that flows through a cooling device.
2. Discussion of Related Art
A switchgear cabinet with a distribution device for supplying a fluid cooling medium to a cooling device, such as in the form of a cooling plate, is described in the catalog “RITTAL-Neuheiten 2005” [RITTAL News 2005], April 2005, on page 59, which also discloses a coolant inlet and outlet and the connection to a recooling plant for a closed cooling circuit. The distribution of the cooling medium, namely water, with corresponding line routing and connecting elements is carried out on a project-by-project basis, with a corresponding amount of installation effort.
Another switchgear cabinet with a similar distribution device for a cooling device is also described in the brochure “RITTAL DCP—Direct Cooling Package” of April 2005.
SUMMARY OF THE INVENTIONOne object of this invention is to provide a switchgear cabinet or rack of the type mentioned above but which achieves a simplified installation of the distribution device for a cooling medium.
This object is attained with a distribution device having characteristics described in this specification and in the claims. The distribution device disclosed is embodied as a main distribution unit installed in the region of or near the base and extends with at least one conduit between two vertical delimitation planes of the base that are parallel to and spaced apart from each other and the conduit has at least one branching piece for connection of the cooling device.
The main distribution unit offers simple connection possibilities for lines that convey the cooling medium to the respective cooling device with a convenient, space-saving installation.
In one embodiment of this invention, an installation and accessibility standpoint comprises at least one conduit that extends between two side faceplates of the base and is connected to the base via at least one side faceplate and/or at least one corner piece.
A simple, stable assembly is advantageously achieved if a main distribution unit has at least one fastening device for attaching the at least one conduit to the base.
A simple installation and a reliable function is advantageously achieved if at least one end section and/or the branching piece of the respective conduit each has a releasable closure element for closing the conduit in a fluid-tight fashion.
Other advantageous measures that contribute to a simple installation and reliable function include the main distribution unit embodied as an add-on distribution unit by attaching a quick-release coupling, which has an insertion element, to one end of each respective conduit. This makes it possible for additional switchgear cabinets or racks, for example, preferably with corresponding main distribution units, to be easily added onto the switchgear cabinet or rack, yielding a simple connection for conducting the cooling fluid.
A convenient accommodation is possible if the base is covered at its top by a base cover plate that has at least one sealed feed-through element for feeding through a connecting line between the respective branching piece and the cooling device.
A simple, stable attachment of the two, for example, but possibly also more, conduits is achieved if the fastening device has two clamping shells that can be clamped against each other, each of which is integrally joined to respective holding receptacles for all of the conduits.
A simple connection, for example, a side-by-side addition of another switchgear cabinet or rack, is achieved if the side faceplates have feed-throughs for the conduits.
In one advantageous arrangement and installation, the side faceplates are a lower partial faceplate and an upper partial faceplate.
In other assembly possibilities, the side faceplates are bent inward at right angles, at least at their upper longitudinal edge, in relation to the base chamber and have fastening holes in the bent section.
This invention is explained in view of preferred exemplary embodiments and with reference to the drawings, wherein:
The base 1 is enclosed at its front and back by a front faceplate 4 and rear faceplate 5, is enclosed laterally by side faceplates 3, and is covered at the top by the base cover plate 6 so that the base faceplates 3, 4, 5, together with the base cover plate 6, enclose a block-shaped base chamber that is separate from a usable space situated or positioned on the interior of the switchgear cabinet, above the base cover plate 6.
The base faceplates are preferably composed of sheet metal wall elements that are bent at right angles, at least at their upper longitudinal edge. The bent edge sections are oriented toward the interior of the base chamber. In a corresponding manner, the narrow sides and/or the lower longitudinal edge of the side faceplates 3 as well as the front faceplate 4 and rear faceplate 5 can also be bent inward at right angles. The bent edges have holes for fastening or mounting purposes, which can be arranged, for example, in rows of holes with a particular spacing pattern, thus providing simple assembly possibilities. In the corner regions of the base 1, corner pieces 2 are provided, which attach the side faceplates 3 to the front faceplate 4 and rear faceplate 5. The front surfaces and rear surfaces of the corner pieces 2 are stepped in parallel fashion or transition flush into the plane of the front faceplate 4 or rear faceplate 5, respectively, and side parts of the corner pieces 2, which are at right angles to the front surface and rear surface, are stepped in parallel fashion or transition flush into the plane of the side faceplates 3.
