High-power vehicle-mounted hybrid electric propulsion device of heat regenerator

The high-power vehicle-mounted hybrid electric propulsion device comprises an electric generator, the outer wall of the electric generator is connected with a turbine case, one side of the turbine case is connected with a free turbine, and the driving end of the free turbine is connected with the driving end of the electric generator; after heat exchange is conducted on high-temperature and high-pressure gas exhausted by the spraying pipe, the high-temperature and high-pressure gas enters the gas chamber to be mixed with fuel, high-temperature and high-pressure gas is continuously generated, flows through the exchange pipe, exchanges heat with the cold fluid and then is exhausted, and the high-temperature and high-pressure gas flows through the gas turbine and the free turbine before flowing into the exchange pipe. When a vehicle runs, the gas turbine and the free turbine are blown to rotate, and the free turbine drives the driving shaft of the generator to rotate to generate power, so that high temperature a
