Power generating and charging device using waste heat of automobile

The utility model provides a power generating and charging device using waste heat of an automobile. The power generating and charging device comprises a first thermoelectric generation sheet group and a second thermoelectric generation sheet group. The thermoelectric generation sheet groups are connected with a vehicle storage battery through a voltage adapter and a charging circuit. A hot surface of the first thermoelectric generation sheet group is contacted with one end of a first inorganic heat superconductive tube, and the other end of the first inorganic heat superconductive tube is positioned in a tail segment of a vehicle exhaust pipe. A cooling water outlet pipeline between a cooling water jacket of a vehicle internal combustion engine and a vehicle radiator is provided with a heat absorption water tank, and an outer wall of the heat absorption water tank is contacted with a hot surface of the second thermoelectric generation sheet group. According to the power generating and charging device, heat generated by the operating internal combustion engine can be converted into electric energy, and the power generating and charging device replaces a conventional vehicle generator for charging a vehicle storage battery, so that on the one hand the fuel utilization efficiency of the internal combustion engine is improved, and on the other hand, the load of the internal combustion engine can be reduced, and power output by the internal combustion engine can be fully used for driving a vehicle to move.
