Abstract

The present invention comprises a Stirling engine, which performs the function of an evaporator and that of a turbine, such that there is no need to separately install an evaporator and a turbine, thereby providing the advantage of a simple configuration, and the same prevents heat loss, which would otherwise occur in the process of heat obtained from the evaporator moving to the turbine, thereby improving the power generating efficiency. Furthermore, a passage, through which an operating fluid passes after undergoing a phase change, is formed in the shape of a nozzle and that of a diffuser, thereby increasing the energy generating efficiency. In addition, power can be generated by evaporating and expanding the operating fluid using low-temperature waste heat, thereby providing applicability to more diversified fields.

도 4 내지 도 7은 도 3에 도시된 스터링 엔진의 작동상태가 도시된 도면이다. 4 to 7 are diagrams showing the operating state of the Stirling engine shown in FIG.
도 4 내지 도 7을 참조하여, 본 발명의 실시예에 따른 스터링 엔진의 작동을 설명하면, 다음과 같다. 4 to 7, the operation of the Stirling engine according to the embodiment of the present invention will be described.
먼저, 도 4를 참조하면, 상기 가열실(11)이 가열되기 이전에 상기 디스플레이서(20)는 하사점(D1)에 위치하고, 상기 플라이 휠(60)은 정지 상태이다. 이 때, 상기 피스톤(40)은 상사점(P1)에 위치한 상태이다. First, referring to FIG. 4, before the heating chamber 11 is heated, the displacer 20 is located at the bottom dead center D1, and the flywheel 60 is in a stopped state. At this time, the piston 40 is in a state located at the top dead center (P1).
이후, 도 5를 참조하면, 상기 가열실(11)이 가열되어 상기 가열실(11) 내부의 작동유체가 가열되어 상변화하게 된다. 기화된 작동유체의 팽창력에 의해 상기 디스플레이서(20)가 상향 이동한다. 상기 디스플레이서(20)가 상향 이동하면, 상기 디스플레이서(20)에 결합된 상기 제1커넥팅 로드(30)가 상향 이동하면서 상기 플라이 휠(60)을 회전시킨다. 상기 디스플레이서(20)가 상기 하사점(DI)로부터 소정 거리만큼 상향 이동하면서 상기 플라이 휠(60)이 시계방향으로 약 90도 회전한다. Subsequently, referring to FIG. 5, the heating chamber 11 is heated so that the working fluid inside the heating chamber 11 is heated to change phase. The displacer 20 is moved upward by the expansion force of the vaporized working fluid. When the displacer 20 moves upward, the first connecting rod 30 coupled to the displacer 20 moves upward to rotate the flywheel 60. The flywheel 60 rotates about 90 degrees clockwise while the displacer 20 moves upward from the bottom dead center DI by a predetermined distance.
이 때, 상기 기화된 작동유체는, 상기 노즐부(12), 상기 통부(13) 및 상기 디퓨저부(14)를 차례로 통과한다. 상기 기화된 작동유체는 상기 디스플레이서(20)를 밀어올림과 동시에, 상기 디스플레이서(20)와 상기 실린더(10)사이의 공간을 통해 상향 이동한다. 상기 기화된 작동유체는, 상기 노즐부(12)를 통과하면서 속도가 증가하게 되므로, 상기 디스플레이서(20)를 미는 힘이 증가할 뿐만 아니라, 상기 냉각실(15)을 향해 보다 빠르게 이동할 수 있다. 또한, 상기 작동유체는 상기 디퓨저부(14)를 통과하면서 상기 냉각실(15)로 확산될 수 있으므로, 상기 냉각실(15)에서의 냉각과 압축이 보다 원활하게 이루어질 수 있다. At this time, the vaporized working fluid passes through the nozzle part 12, the cylinder part 13, and the diffuser part 14 in order. The vaporized working fluid pushes up the displacer 20 and moves upward through the space between the displacer 20 and the cylinder 10. The vaporized working fluid is increased in speed while passing through the nozzle unit 12, so that not only the force pushing the displacer 20 increases but also moves faster toward the cooling chamber 15. . In addition, since the working fluid may diffuse into the cooling chamber 15 while passing through the diffuser unit 14, the cooling and compression in the cooling chamber 15 may be more smoothly performed.
한편, 상기 플라이 휠(60)이 회전하면, 상기 제2커넥팅 로드(50)는 하향 이동한다. 따라서, 상기 제2커넥팅 로드(50)에 결합된 상기 피스톤(40)이 상기 상사점(P1)으로부터 하향 이동한다. 이 때, 상기 냉각실(15)의 외부 냉각원에 의해 냉각되고 있으므로 상기 냉각실(15)로 유입된 작동유체는 냉각되어 액화되고, 상기 피스톤(40)에 의해 압축된다. On the other hand, when the fly wheel 60 rotates, the second connecting rod 50 moves downward. Therefore, the piston 40 coupled to the second connecting rod 50 moves downward from the top dead center P1. At this time, since it is cooled by the external cooling source of the cooling chamber 15, the working fluid introduced into the cooling chamber 15 is cooled and liquefied, and is compressed by the piston 40.
도 6을 참조하면, 상기 디스플레이서(20)가 계속해서 상향 이동하여 상사점(D2)에 도달하고, 상기 플라이 휠(60)의 회전에 따라 상기 제2커넥팅 로드(50)와 상기 피스톤(40)이 하향 이동하여 상기 피스톤(40)은 하사점(P2)에 도달한다. 상기 디스플레이서(20)가 상기 상사점(D2)에 도달할때까지 상기 기화된 작동유체가 상기 냉각실(15)로 유입된다. 상기 피스톤(40)이 상기 하사점(P2)에 도달할때까지 상기 냉각실(15)로 유입된 작동유체는 냉각 압축된다. Referring to FIG. 6, the displacer 20 continuously moves upward to reach the top dead center D2, and the second connecting rod 50 and the piston 40 are rotated as the flywheel 60 rotates. ) Moves downward so that the piston 40 reaches the bottom dead center P2. The vaporized working fluid flows into the cooling chamber 15 until the displacer 20 reaches the top dead center D2. The working fluid introduced into the cooling chamber 15 is cooled and compressed until the piston 40 reaches the bottom dead center P2.
이후, 도 7을 참조하면, 상기 디스플레이서(20)는 상기 상사점(D2)으로부터 하향 이동하고, 상기 피스톤(40)은 상기 하사점(P2)으로부터 상향 이동한다. 상기 냉각실(15)에서 액화된 작동유체는 하향 이동하여 상기 가열실(11)측으로 이동한다. 이 때, 액화된 작동유체는, 상기 디퓨저부(14), 상기 통부(13) 및 상기 노즐부(12)를 차례로 통과하면서 상기 가열실(11)로 돌아간다. Subsequently, referring to FIG. 7, the displacer 20 moves downward from the top dead center D2, and the piston 40 moves upward from the bottom dead center P2. The working fluid liquefied in the cooling chamber 15 moves downward to the heating chamber 11 side. At this time, the liquefied working fluid returns to the heating chamber 11 while sequentially passing through the diffuser portion 14, the cylinder portion 13, and the nozzle portion 12.
상기 가열실(11)로 순환된 작동유체는 다시 상기 가열실(11)에서 가열 팽창되어, 상기와 같은 과정을 반복하게 된다. The working fluid circulated to the heating chamber 11 is again expanded by heating in the heating chamber 11 to repeat the above process.
상기와 같은 본 발명의 실시예에 따른 스터링 엔진은, 작동유체가 상변화후 통과하는 통로를 노즐과 디퓨저 형상으로 형성함으로써, 작동유체의 이동속도가 증가되어 플라이 휠의 회전속도가 증가될 수 있으므로 발전 효율이 보다 향상될 수 있다. 또한, 작동유체가 상기 디퓨저부(14)를 통과하면서 상기 냉각실(15)로 확산되므로, 상기 냉각실(15)로 유입된 작동유체가 보다 빠르게 확산되어 냉각 압축될 수 있으므로 효율이 향상될 수 있다. In the Stirling engine according to the embodiment of the present invention as described above, by forming a passage through which the working fluid passes after the phase change in the shape of a nozzle and a diffuser, since the moving speed of the working fluid is increased, the rotation speed of the flywheel can be increased. Power generation efficiency can be further improved. In addition, since the working fluid is diffused into the cooling chamber 15 while passing through the diffuser portion 14, the working fluid introduced into the cooling chamber 15 can be diffused faster and compressed, thereby improving the efficiency. have.
본 발명에 따르면, 발전 효율이 향상될 수 있는 유기랭킨 사이클 발전 장치를 제조할 수 있다. According to the present invention, it is possible to manufacture an organic Rankine cycle power generation device that can improve the power generation efficiency.
