Abstract

A dehumidifier means includes: an electrothermal converter element; and a collecting container, arranged beneath the electrothermal converter element, for collecting condensate forming thereon, the collecting container having a drain through which the condensate from the collecting container is dischargeable out of the dehumidifier means. In an embodiment, the dehumidifier means includes a support plate on which a holding frame is arranged. The electrothermal converter element is inserted into the holding frame.

First claim

What is claimed is:

1. A dehumidifier, comprising:
an electrothermal converter element; and
a collecting container arranged beneath the electrothermal converter element, and configured to collect condensate forming thereon, the collecting container having a drain through which the condensate from the collecting container is dischargeable out of the dehumidifier,
wherein the drain is arranged over a fan or comprises a fluid connection to a region over the fan such that the condensate is configured to be deposited onto the fan.

2. The dehumidifier of claim 1 , further comprising:
a support plate on which a holding frame is arranged,
wherein the electrothermal converter element is inserted into the holding frame.

3. The dehumidifier of claim 2 , wherein a surface of the electrothermal converter element that faces away from the support plate is a three-dimensionally structured surface.

4. The dehumidifier of claim 2 , wherein:
the fan is arranged such that, during operation of the dehumidifier, an airflow generated thereby blows onto a surface of the electrothermal converter element that faces away from the support plate.

5. The dehumidifier of claim 2 , further comprising:
a thermally conductive pad arranged, in a region of the electrothermal converter element, on a surface of the support plate that faces away from the electrothermal converter element.

6. A charging station for charging an electric vehicle, comprising:
the dehumidifier of claim 1 .

7. The charging station of claim 6 , wherein the dehumidifier is arranged in an upper region of the charging station.

8. The charging station of claim 6 , wherein
the fan has an air supply connection, to which a hose is couplable.

9. The charging station of claim 6 , wherein the dehumidifier further comprises a support plate on which a holding frame is arranged, the electrothermal converter element being inserted into the holding frame,
wherein the dehumidifier further comprises and a thermally conductive pad arranged, in a region of the electrothermal converter element, on a surface of the support plate that faces away from the electrothermal converter element, and wherein the support plate bears with the thermally conductive pad against a cooling plate of a power electronics module of the charging station.

10. The charging station of claim 6 , wherein the drain is arranged in a base region of the charging station.

11. The dehumidifier of claim 1 , further comprising a pump configured to pump condensate via the fluid connection to the region over the fan.

12. The charging station of claim 6 , wherein the fan is configured to discharge condensate to an external environment.

13. The charging station of claim 8 , wherein the hose is configured to draw air from at least one predetermined region of the charging station.

14. The charging station of claim 8 , wherein the hose includes a plurality of air supply openings.

15. The dehumidifier of claim 1 , further comprising:
a support plate coupled to the electrothermal converter element;
a condensation body comprising a three-dimensional structured surface and coupled to the electrothermal converter element; and
a housing, the electrothermal converter element and the condensation body arranged at least partially within the housing,
a fan coupled to the housing;
wherein the electrothermal converter element has a cold side and a hot side,
wherein the condensation body is coupled to the cold side of the electrothermal converter element in a thermally conductive manner, with the three-dimensionally structured surface facing away from the cold side;
wherein the hot side of the electrothermal converter element is coupled to the support plate in a thermally conductive manner,
wherein the fan is configured to blow air toward the three-dimensionally structured surface of the condensation body, and
wherein the collecting container is further configured to collect condensate formed on the three-dimensional structured surface of the condensation body.
