摘要:
This application provides a powertrain cooling system and method, a powertrain, and an electric vehicle, and relates to the field of electric vehicle technologies. The cooling system includes a cooling circuit and a cooling working substance. The cooling circuit includes a first cooling channel and a second cooling channel that are connected. The first cooling channel is configured to dissipate heat of an inverter of the electric vehicle. The second cooling channel is configured to dissipate heat of a motor of the electric vehicle. The cooling working substance is an insulating working substance, and the cooling working substance flows from the first cooling channel into the second cooling channel. The cooling system can improve an effect of dissipating heat of the powertrain.
