<p>The invention relates to a cooling device for an electric energy supply (2), comprising at least one first heat-dissipating part (3), the power components (4) of which are connected to the cooling device (1) in a thermally conductive manner, wherein a fluid-conducting connection (5) conducts liquid coolant (6) from a pump (7) to a cooler (8over the first heat-dissipating part (3), wherein one shut-off unit (9′, 9) each is arranged in the fluid-conducting connection (5) at least between the first heat-dissipating part (3) and the cooler (8) and between the pump (7) and the first heat-dissipating part (3). The cooling device is characterized in that, in order to avoid an overpressure in at least one part (3, 14) to be cooled, at least one pressure limiting valve (17, 28) is provided, which is arranged in connection with the fluid conductor inside the part (3, 14) and/or, as part of a unit (15) for preloading the cooling liquid (6) in the fluid-conducting connection (5), is connected to the part (3, 14) by means of the pressure sure side of a check valve (13) provided downstream of the part (3, 14).</p> |
