Inverter and method for cooling an inverter

1. An inverter, in particular for a photovoltaic system, comprising: a housing with at least one chamber and a cooling air channel formed within the chamber for guiding ambient air as cooling air for electrical and/or electronic components of the inverter disposed along the cooling air channel, wherein the cooling air channel extends through the housing from an air inlet to an air outlet, thereby defining an air flow path, and a further air outlet provided within the cooling air channel between two of the components of the inverter to be cooled along the airflow path, and arranged above the air inlet and the air outlet.

2. The inverter of claim 1 , wherein the further air outlet is adjustable with regard to its effective air outlet cross section.

3. The inverter of claim 1 , wherein the cooling air channel is folded and formed as a meander.

4. The inverter of claim 1 , wherein the air outlet and the further air outlet are arranged at different sides of the housing.

5. The inverter of claim 1 , further comprising:

a further chamber formed inside the housing and beside the chamber,

wherein the chamber and the further chamber are separated from each other such that an exchange of air between the chamber and the further chamber is prevented, and

wherein the chamber meets the requirements of a first protection class and the further chamber meets the requirements of a second, different protection class.

6. The inverter of claim 5 , wherein the chamber comprising the cooling air channel is assigned to a lower protection class than the further chamber.

7. The inverter of claim 1 , further comprising a fan arranged within or at the cooling air channel of the housing.

8. An inverter, in particular for a photovoltaic system, comprising:

a housing with at least one chamber and a cooling air channel formed within the chamber for guiding ambient air as cooling air for electrical and/or electronic components of the inverter disposed along the cooling air channel,

wherein the cooling air channel extends through the housing from an air inlet to an air outlet, thereby defining an air flow path, and

a further air outlet provided within the cooling air channel between two of the components of the inverter to be cooled along the airflow path, and arranged above the air inlet and the air outlet, wherein a component of the inverter to be cooled with a maximum cooling requirement is disposed between the air inlet and the further air outlet.

9. The inverter of claim 8 , wherein the component of the inverter disposed between the air inlet and the further air outlet comprises a cooling body of at least one inverter bridge of the inverter.

10. An inverter, in particular for a photovoltaic system, comprising:

a housing with at least one chamber and a cooling air channel formed within the chamber for guiding ambient air as cooling air for electrical and/or electronic components of the inverter disposed along the cooling air channel,

wherein the cooling air channel extends through the housing from an air inlet to an air outlet, thereby defining an air flow path, and

a further air outlet provided within the cooling air channel between two of the components of the inverter to be cooled along the airflow path, and arranged above the air inlet and the air outlet, wherein a further component of the inverter to be cooled with reduced cooling requirement is disposed between the air outlet and the further air outlet.

11. The inverter of claim 10 , wherein the further component of the inverter disposed between the air outlet and the further air outlet comprises at least one inductor coil of the inverter.

12. The inverter of claim 11 , wherein the at least one inductor coil is part of a DC converter connected upstream of the inverter bridge.

13. The inverter of claim 11 , wherein the at least one inductor coil is part of an output current filter connected downstream of the inverter bridge.

14. The inverter of claim 11 , wherein the at least one inductor coil comprises a ferrite core.
