| Abstract: | According to the industrial radiator heat exchange principle,a cooling system power testing platform which can actually measure the cooling power of EMU traction converter is established based on the heat exchange formula.A precise method to calculate the cooling power is presented by analyzing the cooling system under different conditions.The method is applied to measuring the actual power of the cooling system of the particular EMU traction converter.The result shows that the actual measured value can meet the requirement of vehicles and the method can be widely used in the cooling power measurement of the cooling system of EMU traction converter. |
