The invention discloses a natural air interchanger utilizing train traveling power and relates to the field of train ventilating systems. The natural air interchanger utilizing train traveling power is characterized in that a positive-pressure ventilation pipe and a negative-pressure ventilation pipe are both straight pipes; the diameter of the negative-pressure ventilation pipe is equal to that of the positive-pressure ventilation pipe; the negative-pressure ventilation pipe is connected with a negative-pressure nozzle, the top of the negative-pressure nozzle is a streamline arc surface protruding outwards, the top end of the negative-pressure nozzle is connected with train roof skin, the negative-pressure ventilation pipe penetrates through the lower portion of a train roof equipment bin to be connected with a compartment ceiling, and the pipe orifice of the negative-pressure ventilation pipe is located in a compartment; the top end of the positive-pressure ventilation pipe is connected with the train roof skin, the lower end of the positive-pressure ventilation pipe is located in the compartment, and the top end of the positive-pressure ventilation pipe is flush with the train roof skin; ventilation pipe semicircular through holes are formed in the middle section of the positive-pressure ventilation pipe and the middle section of the negative-pressure ventilation pipe, and an automatic water seal door assembly is mounted below the train roof skin. The air interchanging effect of the natural air interchanger utilizing train traveling power is better than that in the prior art, the structure is simple, and cost is low.
