Abstract
A cooling system for an electric traction machine for a motor vehicle, including a circuit system for conducting a first coolant to be circulated, a first circulation pump for conveying the first coolant in the circuit system, an AC housing for an AC connection for the electric traction machine, and a motor inlet connection for fluidly connecting the circuit system on the input side to the electric traction machine to be temperature-controlled. The cooling system further includes a motor outlet connection for fluidly connecting the circuit system on the output side to the electric traction machine to be temperature-controlled, a first heat exchanger for dissipating heat from and/or supplying heat to the first coolant to be circulated in the circuit system, and a first main line, by which the first heat exchanger and the AC housing are fluidly connected to one another.
