Abstract

A control cabinet arrangement, comprising a cooling device which is received in a control cabinet housing, wherein the cooling device can be slidably held on the control cabinet housing via a linear adjusting unit, particularly a bar system, and can be adjusted between a pull-out position and a slide-in position, wherein the cooling device in the slide-in position is completely received in the control cabinet housing, and in the pull-out position, the cooling device protrudes at least partially beyond a door side of the control cabinet housing from the control cabinet housing, and wherein a door element, which closes in its closed position the door side of the control cabinet housing, comprises at least one air passage opening which opens into an air outlet and/or an air inlet of the cooling device in the closed position of the door element, when the cooling device is in the slide-in position.

First claim

The invention claimed is:

1. A control cabinet arrangement, comprising a cooling device which is received in a control cabinet housing, wherein the cooling device can be slidably held on the control cabinet housing via a linear adjusting unit, including a bar system, and can be adjusted between a pull-out position and a slide-in position, wherein the cooling device in the slide-in position is completely received in the control cabinet housing, and in the pull-out position, the cooling device protrudes at least partially beyond a door side of the control cabinet housing from the control cabinet housing, wherein a door element, which closes in its closed position the door side of the control cabinet housing, comprises at least one air passage opening which opens into an air outlet and/or an air inlet of the cooling device at least in the closed position of the door element, when the cooling device is in the slide-in position, and a sealing element on an inner side of the door element, the sealing element completely surrounding the air passage opening, the air passage opening including both the air inlet opening and the air outlet opening, the air inlet opening is opposite to the air inlet of the cooling device when the door element is closed, and the air outlet opening is opposite to the air outlet of the cooling device when the door element is closed;
wherein the cooling device has a cooling device housing with an air inlet side and an air outlet side that face and are arranged parallel to the door element when the door element is in the closed position;
wherein in the closed position, both the air outlet and the air inlet of the cooling device open into the air passage opening;
wherein the air passage opening is designed in two parts with an air inlet opening, which opens into the air inlet of the cooling device, and an air outlet opening, which is fluidically separated from the air inlet opening and opens into the air outlet of the cooling device.

2. A control cabinet arrangement according to claim 1 , in which the air inlet opening and the air outlet opening are fluidically separated from one another by a separator dividing the air passage opening, wherein the separator has a protruding partition, including a brush strip, on the door inner side which faces the cooling device in the closed position of the door element, and so an air short-circuit between air inlet and air outlet is prevented.

3. A control cabinet arrangement according to claim 1 , in which at least the air outlet opening has an air guide geometry, including lamellas, which are designed to guide air escaping from the control cabinet housing via the air outlet opening in a direction facing away from the air inlet opening.

4. A control cabinet arrangement according to claim 1 , in which the air passage opening is or has an air inlet opening which, downstream in the air flow direction through the air inlet opening, has an air filter, including a filter mat, facing the door inner side of the cooling device in the closed position of the door element.

5. A control cabinet arrangement according to claim 1 , in which the cooling device is a horizontal slide-in device which is adjustable in a slide-in plane parallel to a roof side and/or a floor side of the control cabinet housing, or in which the cooling device is a vertical slide-in device which is adjustable in a slide-in plane parallel to a side wall of the control cabinet.

6. A control cabinet arrangement according to claim 5 , in which the cooling device,
a) if it is a horizontal slide-in device, extends on its front side, which faces the door element, over the entire horizontal clearance of the control cabinet interior, and
b) if it is a vertical slide-in device, extends on its front side, which faces the door element, over the entire clear vertical installation dimension of the control cabinet interior,
wherein on its rear side, which faces a rear wall of the control cabinet housing, the cooling device has a bus bar transfer space designed as a horizontal opening through the cooling device.

7. A control cabinet arrangement according to claim 1 , in which the door element is either a control cabinet door pivotably attached by means of hinges to the control cabinet housing, or a door panel mounted on a vertical housing side of the cooling device which faces the door side of the control cabinet housing in the slide-in position, and which is adjustable perpendicularly to the door side.

8. A control cabinet arrangement according to claim 7 , in which the door panel is firmly connected to the housing side of the cooling device and has a handle on its outer side facing away from the cooling device, and so the cooling device with the door panel is adjustable between the slide-in position and the pull-out position.

9. The control cabinet arrangement according to claim 1 , wherein each one of the air outlet and the air inlet of the cooling device extends laterally across the cooling device opposite to a width of the door element when the door element is closed.

10. The control cabinet arrangement according to claim 1 , wherein the air inlet of the cooling device is larger than the air outlet of the cooling device.

11. A control cabinet arrangement, comprising a cooling device which is received in a control cabinet housing, wherein the cooling device can be slidably held on the control cabinet housing via a linear adjusting unit, including a bar system, and can be adjusted between a pull-out position and a slide-in position, wherein the cooling device in the slide-in position is completely received in the control cabinet housing, and in the pull-out position, the cooling device protrudes at least partially beyond a door side of the control cabinet housing from the control cabinet housing, wherein a door element, which closes in its closed position the door side of the control cabinet housing, comprises at least one air passage opening which opens into an air outlet and/or an air inlet of the cooling device at least in the closed position of the door element, when the cooling device is in the slide-in position;
wherein the cooling device has a cooling device housing with an air inlet side and an air outlet side, which, at least in the closed position of the door element, face and are preferably arranged parallel to the door element;
wherein in the closed position, both the air outlet and the air inlet of the cooling device open into the air passage opening, wherein the air passage opening is designed in two parts with an air inlet opening, which opens into the air inlet of the cooling device, and an air outlet opening, which is fluidically separated from the air inlet opening and opens into the air outlet of the cooling device; and
wherein an outer side of the door element, a device display of the cooling device is arranged, wherein a connection cable of the device display is guided through the door element and emerges from the door element on a door inner side which faces the cooling device in the closed position of the door element, wherein on its front side facing the door element, the cooling device has a cable box for receiving the connection cable.

12. The control cabinet arrangement according to claim 11 , wherein the cable box has a cable entry, through which the connection cable emerging on the door inner side of the door element enters the cooling device, wherein the connection cable is preloaded in the direction of the cable entry.
