Abstract (en)
[origin: WO2019086441A1] A railroad vehicle (1) comprises an electric power conversion device (10), a cooling circuit (15) comprising a fluid, which is thermally connected to the electric power-conversion device (10) and comprises at least one heat-exchanger (20, 21) for dissipating thermal energy from the electric power-conversion device (10) to surrounding air, wherein at least one side wall (30, 31) of the railroad vehicle (1) comprises at least one opening (40, 41, 45, 46, 47, 48), and wherein the at least one heat exchanger (20, 21) is arranged to be cooled by an air flow through the at least one opening (40, 41, 45, 46, 47, 48) caused by a movement of the railroad vehicle (1), wherein the at least one heat exchanger (20, 21) and the at least one opening (40, 41, 45, 46, 47, 48) are located at a roof level of the railroad vehicle (1). Further, a respective cooling method for an electric power conversion device located at a roof level of a railroad vehicle is provided.
