In order to keep the temperature difference on the heat exchanger in a cooling device for a current converter module as low as possible, a cooling device has a cooling liquid channel, which conducts a liquid coolant and which is connected to a cooling circuit, a heat exchanger, which is connected in the cooling circuit and to which a power component is coupled in a thermally conductive manner, and a cooler for cooling the liquid coolant, which cooler is connected in the cooling circuit, wherein a plurality of pipelines is connected in parallel in the heat exchanger in such a way that the temperature difference on the heat exchanger does not exceed a specified quantity. |
