With the development of traction converter for electric locomotive toward large capacity, the heat dissipation of IGBT becomes increasingly serious. Based on the principle of self-driven evaporative cooling, a self-driven evaporative cooling scheme with cooling plate structure is proposed. A prototype of self-driven evaporative cooling system for traction converter is designed and developed using insulated organic liquid with high evaporative latent heat, low boiling point and non-flammable as coolant. The prototype runs steadily under the load of 15kW, and the temperature of the cooling plate does not exceed $83^{\circ}C$ and the surface temperature difference does not exceed 3K. Compared with the traditional water cooling system, it achieves better cooling performance and provides a new reference for the future cooling system design of traction converter for electric locomotive.
