有鉴于此，本发明提供一种涡旋发动机，以解决现有发动机热效率低、能耗大等的技术问题。
本发明涡旋发动机，包括外壳，还包括设置在外壳内的转轴，所述转轴的一端连接有涡旋体，转轴的另一端连接有压气叶轮，所述涡旋体和压气叶轮之间设置有管状隔离罩，所述隔离罩固定在外壳上，所述隔离罩和外壳之间形成工作腔，所述外壳上设置有向工作腔内喷入工作介质的喷嘴，所述涡旋体由按螺旋线形弯曲绕在转轴上的螺旋管组成，所述螺旋管为一根或沿转轴圆周方向均匀布置的至少两根；所述螺旋管的径向截面轮廓由弧形线段连接组成。
进一步，所述螺旋线形弯曲为圆锥形螺旋线形弯曲或圆柱形螺旋线形弯曲。
进一步，所述隔离罩的两端内壁上设置有圆环形的突起，所述转轴上设置有密封体，所述密封体上设置有与隔离罩上圆环形突起配合的环形凹槽，所述圆环形突起和环形凹槽构成迷宫式密封结构。
本发明的有益效果：
1、本发明涡旋发动机，其工作原理为：工作介质经喷嘴进入隔离罩与外壳之间的工作腔后，再进入螺旋管中，从而驱动涡旋体旋转，涡旋体旋转通过转轴带动压气叶轮旋转，压气叶轮将压缩介质推进工作腔，压缩介质再进入螺旋 管中实现连续驱动涡旋体旋转，做功后的工作介质从螺旋管的尾端排出，涡旋体的旋转动力可通过与涡旋体或转轴连接的输出轴将动力输出。本涡旋发动机的工作介质可以为燃气、蒸汽、压缩空气、液体，可普遍运用在汽车、轮船、飞机、发电机等领域，适用范围广，实用性强。
