1. supercritical fluid formula external combustion heat engine, it is made up of air guide cylinder chamber (1), air guide piston (2), acting cylinder chamber (3), acting piston (4), flywheel crankshaft assembly (5), valve (6), carbon dioxide (7), gas working medium (8), closed shell (9), generator (10);

  • Be provided with multilayer heat accumulation air guide wire netting (2-2) in the internal cavities (2-1) of air guide piston (2);

    Respectively having through hole (2-3) on the both ends of the surface of air guide piston (2) is communicated with its internal cavities (2-1);

    Air guide piston (2) is arranged in the air guide cylinder chamber (1);

    Back first curved bar (5-1) with flywheel crankshaft assembly (5) of slipper seal cover (1-1) that the connecting rod (2-4) of air guide piston (2) passes an end of air guide cylinder chamber (1) is rotationally connected, and drives air guide piston (2) when the bent axle (5-2) of flywheel crankshaft assembly (5) rotates and in air guide cylinder chamber (1), does left and right sides to-and-fro motion, and the left end of air guide cylinder chamber (1) is a cold junction;

    Right-hand member is the hot junction, or opposite;

    Acting piston (4) is arranged in the acting cylinder chamber (3);

    The connecting rod (4-1) of the left end of acting piston (4) is rotationally connected with second curved bar (5-3) of flywheel crankshaft assembly (5);

    Air guide cylinder chamber (1) is communicated with the right-hand member of acting cylinder chamber (3), and first curved bar (5-1) of flywheel crankshaft assembly (5) and the rotation angle between second curved bar (5-3) are 90 degree;

    Air guide cylinder chamber (1) is connected with an external valve (6) with the enclosed cavity that the right-side cavity of acting cylinder chamber (3) is communicated with;

    The conducting starting point of valve (6) is between preceding 20 degree in the top in the hot junction that air guide piston (2) moved to air guide cylinder chamber (1) when bent axle (5-2) rotated in the flywheel crankshaft assembly (5) to back 20 degree;

    The angle of flow of valve (6) is that 5 degree are to 30 degree;

    The movable sealing place of above-mentioned all parts and the external conducting port (6-1) of valve (6) all are enclosed in the closed shell (9);

    Bent axle (5-2) upper end is connected with generator (10) spindle in the flywheel crankshaft assembly (5);

    It is characterized in that said gas working medium (8) is nitrogen or inert gas;

    Be filled with carbon dioxide (7) and gas working medium (8) in the closed shell (9);

    Pressure in the closed shell (9) is between 7.4 MPa to 10 MPa;

    Make carbon dioxide (7) be in the supercritical carbon dioxide fluid state, air guide cylinder chamber (1), air guide piston (2), acting cylinder chamber (3), acting piston (4), flywheel crankshaft assembly (5), valve (6) all are arranged on the lower end of closed shell (9), make that air guide cylinder chamber (1) inside, air guide piston (2), acting cylinder chamber (3) are inner, the piston (4) that does work, flywheel crankshaft assembly (5), valve (6) all be immersed in the supercritical carbon dioxide fluid;

    The liquid level top of supercritical carbon dioxide fluid is gas working medium (8);

    Generator (10) is arranged on the supercritical carbon dioxide fluid liquid level, and the hot-side temperature of air guide cylinder chamber (1) is arranged between 50 ℃



    130 ℃

    , and the cold junction temperature of air guide cylinder chamber (1) is arranged between 32 ℃



    40 ℃
