1. A cooling tank installation for a liquid cooling of a charging station for electrically powered motor vehicles, comprising:
at least one reservoir (12, 14) having a plurality of reservoir walls defining an enclosed reservoir volume for receiving an environmentally hazardous liquid cooling medium;
a retention vessel (16) having retention vessel walls defining a retention vessel volume, the reservoir (12, 14) being inserted in the retention vessel volume while leaving sufficient excess retention vessel volume between the at least one reservoir (12, 14) and the retention vessel (16) for receiving all of the cooling liquid from the at least one reservoir (12, 14);
an outer vessel (20) for providing support for the cooling tank installation with respect to earth loads, the outer vessel (20) having outer vessel walls defining an outer vessel volume, the retention vessel (16) being inserted in the outer vessel volume of the outer vessel (20);
an absorption body (24) for absorbing moisture being provided in the outer vessel volume of the outer vessel (20) between the retention vessel (16) and the outer vessel (20) in a direction of gravity;
a moisture sensor disposed between the retention vessel (16) and the outer vessel (20) for detecting the moisture of the absorption body (24); and
a viewing tube (26) between the outer vessel (20) and the retention vessel (16) and led out from the outer vessel (20) for visual examination of at least one of the absorption body (24), the outer vessel (20) and the retention vessel (16), the viewing tube (26) reaching the absorption body (24), a moisture detecting wire of the moisture sensor being led to the absorption body (24) through the viewing tube (26).
