There is provided a turbocharging apparatus and vehicles using the same. The turbocharging apparatus comprises a wind collecting device, a first turbine and a second turbine. The wind collecting device comprises a first opening and a second opening and an air flow channel for connecting the two openings. A cross-sectional area of the air flow channel decreases as the air flow channel extends from the first opening towards the second opening. The first turbine comprises a first turbine housing, a first impeller rotatably located in the first turbine housing, a wind inlet communicated with the second opening, and a wind outlet. The second turbine comprises a second turbine housing, a second impeller rotatably located in the second turbine housing, an air suction inlet and an air outlet communicated with a throttle valve of the internal combustion engine. The second impeller can, driven by the first impeller, rotate along with the first impeller. The turbocharging apparatus according to the present invention relies on normal-temperature gas flow as a motive power source, substantially reduces production costs and maintenance costs, and meanwhile better ensures stability, high efficiency and durability of the turbocharger. 1. A turbo charging apparatus , characterized in that it comprises:a wind collecting device which is barrel-shaped and comprises a first opening and a second opening located at opposite ends of the wind collecting device respectively, and an air flow channel configured to connect the first opening and the second opening and guide an air flow to flow therethrough, the air flow channel having a cross-sectional area decreasing as the air flow channel extending from the first opening towards the second opening,a first turbine comprising:a first turbine housing,a first impeller rotatably located in the first turbine housing,a wind inlet formed on the first turbine housing and connected to the second opening of the wind collecting device to guide the air ...
