Abstract
A cooling device for an electric energy supply () has at least one first heat-dissipating part (). The power components () of the first heat-dissipating part are connected to the cooling device () in a thermally conductive manner. A fluid-conducting connection () conducts liquid coolant () from a pump () to a cooler () over the first heat-dissipating part (). One shut-off unit () each is arranged in the fluid-conducting connection () at least between the first heat-dissipating part () and the cooler () and between the pump () and the first heat-dissipating part (). To avoid an overpressure in at least one part () to be cooled, at least one pressure-limiting valve () is provided. The pressure-limiting valve is arranged in connection with the fluid conductor inside the part () and/or, as part of a unit () for preloading the cooling liquid () in the fluid-conducting connection () and is connected to the part () of the pressure side of a check valve () provided downstream of the part ().
