An apparatus for cooling electrical devices which are at different electrical potentials by means of a flowing medium, preferably water, wherein the potential difference prevailing between those electrically conductive devices exhibiting the greatest potential difference drops at control electrodes. These control electrodes essentially possess the same potential as the associated electrically conductive devices. The remaining electrically conductive devices are arranged parallel to the aforementioned electrically conductive devices between the control electrodes at equipotential points relative to their own potential.
