By using coolant distributor 60, liquid coolant 64 is applied directly to the thermal source in the power electronic equipment, is about to the power transistor 52 that direct current converts interchange to.Cooling makes the power density (power of per unit volume) of inverter circuit 28 to increase.In order to be cooled off by liquid coolant 64, the heat that is produced by power transistor 52 does not need to pass multilayer material, and some in the described material have low heat conductivity.On the contrary, the direct heat path that is provided by the spraying cooling reduces the temperature of power transistor 52.Have at power transistor 52 under the situation of lower temperature, can obtain by the power of inverter circuit 28 to the increase of three-phase traction motor 16.Perhaps,, can use less inverter circuit 28 to produce the essentially identical available horsepower of traction electric machine 16, take less space simultaneously by the cooling that improves.
