RAIL TRAIN, RAIL TRAIN HEAT DISSIPATION SYSTEM, AND HEAT DISSIPATION METHOD THEREOF

Disclosed in the present invention are a rail train, a rail train heat dissipation system, and a heat dissipation method thereof. Absorbed heat of a heat generation device is brought into a traveling air heat dissipation apparatus by means of flowing of a liquid heat conduction medium in a pipeline, traveling air generated when a train runs at a high speed is used to dissipate heat of the liquid heat conduction medium storing the heat, the cooled liquid heat conduction medium flows back into a heat taking apparatus for heat collection, and the circulation is carried out in this way, such that heat dissipation of the heat generation device is realized. The temperature of the liquid heat conduction medium is measured by means of a temperature sensor, and the number of starting heat dissipation modules in the traveling air heat dissipation apparatus and/or the flow rate of the liquid heat conduction medium in the traveling air heat dissipation apparatus are/is controlled according to the temperature, such that the temperature of the liquid heat conduction medium at an outlet or an inlet of the heat taking apparatus is within a threshold range, and the balance control of the heat generation amount and the heat dissipation amount is achieved. The heat dissipation performance is remarkably improved, the outstanding performances of saving energy and reducing noise and cost are achieved, and the volume and weight of the heat dissipation apparatus are greatly decreased.
