The invention discloses an automobile exhaust waste heat thermoelectric generator device adopting phase change materials. The automobile exhaust waste heat thermoelectric generator device comprises a heat conductor, which is fixedly attached to an exhaust pipe. A heat thermoelectric generator is fixedly disposed on the heat conductor, and the heat end of the heat thermoelectric generator is attached to the outer surface of the heat conductor, and the cold end of the heat thermoelectric generator is provided with a radiator. The side of inner part of the heat conductor close to the heat thermoelectric generator is provided with a phase change material accommodation cavity, in which are disposed phase change materials in a filled manner. By disposing the phase change materials on the output end of the heat conductor, the temperature of the heat end of the heat thermoelectric generator adopting the phase change materials is kept in a stable range, and therefore the performance of the heat thermoelectric generator and the stability of the output voltage are greatly improved, and the service lifetime of the heat thermoelectric generator is prolonged to a certain extent.
