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 means, comprising:
an electrothermal converter element; and a collecting container, arranged beneath the electrothermal converter element, 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 means.

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

4 . The dehumidifier means of claim 1 , further comprising:
a fan arranged such that, during operation of the dehumidifier means, an airflow generated thereby blows onto a surface of the electrothermal converter element that faces away from the support plate.

5 . The dehumidifier means 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 means of claim 1 , wherein the drain of the dehumidifier means is fluidically coupled to an outlet configured to discharge the condensate from the charging station.

7 . A charging station for charging an electric vehicle, comprising:
the dehumidifier means of claim 1 , wherein the drain of the dehumidifier means is arranged over a fan of the charging station, or is conveyed by a fluid connection to a region over a fan of the charging station, such that, during operation of the charging station, the condensate flowing through the drain is deposited onto the fan.

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

9 . The charging station of claim 6 , wherein the dehumidifier means further comprises a fan arranged such that, during operation of the dehumidifier means, an airflow generated thereby blows onto a surface of the electrothermal converter element that faces away from the support plate, and
wherein the fan has an air supply connection, to which a hose is couplable.

10 . The charging station of claim 6 , wherein the dehumidifier means 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 means 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.

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