The utility model discloses a helical tubular turbine and a turbine. The helical tubular turbine comprises a trumpet-shaped wheel body composed of several helical tubular airways arranged in an array along the circumferential direction. The inlet of the helical tubular airway is located on the circumferential surface of the large end of the wheel body, and the outlet of the helical airway is located on the circumferential surface of the large end of the wheel body. On the end face of the small end of the wheel body, the inlet direction of the helical tube-shaped air passage is perpendicular to the axis of the mounting hole of the wheel axle. The turbine comprises a wheel axle, and the end of the wheel axle is connected with a helical tubular turbine. In the utility model, the intake holes of the helical tubular turbine are arranged on the circumferential surface of the wheel body, which eliminates the problem of low energy utilization ratio of the existing vane turbine to the gas near the middle of the turbine, and improves the conversion rate of the gas energy; moreover, compared with the helical blades on the existing turbine, the helical tubular airway is connected with the gas. The contact surface is larger, which can further improve the utilization rate of gas energy.
