Abstract

A cooling device, in particular for a switchgear cabinet with a housing, in which a refrigeration cycle system is housed, wherein the refrigeration cycle system has vibration-generating elements, namely a compressor and at least one fan. The fan and the compressor are supported in the housing via vibration dampers. For preventing vibratory emissions a cooling device in accordance with this invention has the fan and/or the compressor separately supported by first vibration dampers on an intermediate bracket, or together on an intermediate bracket. The intermediate bracket is supported by second vibration dampers on a bracket, and the bracket is connected to the housing.

Claims

1. A cooling device, such as for a switchgear cabinet with a housing, in which a refrigeration cycle system is housed, wherein the refrigeration cycle system has vibration-generating elements including a compressor (20.2) and at least one fan (20.1), wherein the at least one fan (20.1) and the compressor (20.2) are supported in the housing via vibration dampers (14.2, 14.1), the cooling device comprising:

at least one of the fan (20.1) and the compressor (20.2) one of separately supported by first vibration dampers (14.1) on an intermediate bracket (16) and supported together on an intermediate bracket (16.1), the intermediate bracket (16) supported by second vibration dampers (14.2) on a bracket (10), and the bracket (10) connected to the housing.

2. The cooling device in accordance with claim 1, wherein the refrigeration circuit system has two fans (20.1) each respectively assigned to an air circuit, and the two fans (20.1) are respectively supported on the housing by a first vibration damper and a second vibration damper (14.1, 14.2), and by a respective intermediate bracket (16).

3. The cooling device in accordance with claim 2, wherein the intermediate bracket (16) which supports the compressor (20.2) is a sheet metal component with bevels (10.1, 10.2) along edges.

4. The cooling device in accordance with claim 3, wherein the intermediate bracket (16) supporting the compressor (20.2) is supported by the second vibration dampers (14.2) on the bracket embodied as a console (10), and the bracket (10) is welded to the housing.

5. The cooling device in accordance with claim 4, wherein the fan (20.1) is arranged in an area between the bracket (10) and the intermediate bracket (16), and the bracket (10) is connected by spacing elements (13) to the intermediate bracket (16).

6. The cooling device in accordance with claim 5, wherein the intermediate bracket (16) is connected with the spacing elements (13) by the second vibration dampers (14.2).

7. The cooling device in accordance with claim 6, wherein an air nozzle (12) is formed on the bracket (10), which is directed to an aspiration area of the fan (20.1).

8. The cooling device in accordance with claim 7, wherein the vibration damper (14.1, 14.2) has a damping element (14.22) with a cylindrical holding shoulder and an adjoining collar section, a further damping element (14.21) with a bore is pushed on the holding shoulder, and a plate-shaped section of one of the bracket (10) and the intermediate bracket (16) is clampingly held between the damping element (14.21) and the collar section.

9. The cooling device in accordance with claim 1, wherein the intermediate bracket (16) which supports the compressor (20.2) is a sheet metal component with bevels (10.1, 10.2) along edges.

10. The cooling device in accordance with claim 1, wherein the intermediate bracket (16) supporting the compressor (20.2) is supported by the second vibration dampers (14.2) on the bracket embodied as a console (10), and the bracket (10) is welded to the housing.

11. The cooling device in accordance with claim 1, wherein the fan (20.1) is arranged in an area between the bracket (10) and the intermediate bracket (16), and the bracket (10) is connected by spacing elements (13) to the intermediate bracket (16).

12. The cooling device in accordance with claim 11, wherein the intermediate bracket (16) is connected with the spacing elements (13) by the second vibration dampers (14.2).

13. The cooling device in accordance with claim 5, wherein an air nozzle (12) is formed on the bracket (10), which is directed to an aspiration area of the fan (20.1).

14. The cooling device in accordance with claim 1, wherein the vibration dampers (14.1, 14.2) each has a damping element (14.22) with a cylindrical holding shoulder and an adjoining collar section, a further damping element (14.21) with a bore is pushed on the holding shoulder, and a plate-shaped section of one of the bracket (10) and the intermediate bracket (16) is clampingly held between the damping element (14.21) and the collar section.
