Abstract

The invention relates to an inverter casing, said inverter casing comprising in the bottom at least one depression for receiving heat dissipating electric components, coils in particular.

Claims

1. An inverter comprising a casing with at least two casing chambers, a first casing chamber accommodating power components of the inverter and wherein at least one depression for receiving heat dissipating electric components is provided in a bottom of the first casing chamber and the depression is covered by a partition plate.

2. The inverter as set forth in claim 1, wherein the partition plate is configured to be heat insulating.

3. The inverter as set forth in claim 1, wherein the casing further comprises cooling ribs on the outer side of the depression.

4. The inverter as set forth in claim 3, wherein the cooling ribs are disposed to the side of the depression on the outer side of the casing bottom.

5. The inverter a set forth in claim 1 wherein the heat dissipating electric components comprise a coil.

6. An inverter comprising a casing with at least one depression for receiving heat dissipating electric components in a bottom of the casing and wherein the depression is covered by a partition plate.

7. The inverter a set forth in claim 6, wherein the partition plate is configured to be heat insulating.

8. The inverter as set forth in claim 6, wherein the casing further comprises cooling ribs on the outer side of the depression.

9. The inverter as set forth in claim 8, wherein the cooling ribs are disposed to the side of the depression on the outer side of the casing bottom.

10. The inverter as set forth in claim 6 wherein the heat dissipating electric components comprise a coil.

11. The inverter as set forth in claim 6 wherein the casing comprises a first casing chamber and a second casing chamber, the first casing chamber accommodating power components of the inverter, the depression being provided in a bottom of the first chamber.

12. An inverter comprising a casing with at least one depression for receiving heat dissipating electric components in a bottom of the casing and wherein cooling ribs are disposed on the outer side of the depression and the depression is covered by a partition plate.

13. The inverter as set forth in claim 12, wherein the partition plate is configured to be heat insulating.

14. The inverter easing as set forth in claim 12, wherein the cooling ribs are disposed to the side of the depression on the outer side of the casing bottom.

15. The inverter as set forth in claim 12 wherein the heat dissipating electric components comprise a coil.

16. The inverter as set forth in claim 12 wherein the casing comprises a first casing chamber and a second casing chamber, the first casing chamber accommodating power components of the inverter, the depression being provided in a bottom of the first chamber.
