  • Publication number: 20140041835
    Abstract: A cooling device for a vehicle battery with battery cells, and which includes a cooling body which thermally contacts the battery cells. The cooling body has channels through which a coolant flows. A coolant distributor is provided on the cooling body and includes an inflow and/or an outflow for coolant which is fluidically connected to certain channels. A first flow opening is formed at the inflow and/or outflow of the coolant distributor and extends in a direction of a main channel of the channels, the main channel being the channel which is furthest away from the inflow and/or outflow.
