An air cooled type generator includes a housing, an engine, a cooling fan mounted in the engine, a generator body having a first side juxtaposed to the engine, and a cooling fan rotatably mounted on an opened second side of the generator body and including a plurality of blades each having an inner side formed with a first wing and an outer side formed with a second wing. Thus, the first wing and the second wing of each of the blades co-operate to carry the hot air away from the generator body rapidly, thereby enhancing the heat dissipation effect of the cooling fan. In addition, the generator only needs to provide two cooling fans to achieve the heat dissipation effect, so that the generator has a simplified construction and a smaller volume and is assembled easily and conveniently.

What is claimed is: 1. A generator, comprising: a housing; an engine mounted in the housing; a generator body mounted in the housing and having a first side juxtaposed to the engine; a cooling fan rotatably mounted on an opened second side of the generator body and including a plurality of blades each having an inner side formed with a first wing located adjacent to the second side of the generator body and an outer side formed with a second wing spaced from the second side of the generator body; wherein the housing has an outer side formed with a plurality of air inlets; wherein the air inlets of the housing have changeable positions. 2. The generator in accordance with claim 1, wherein the first wing of each of the blades of the cooling fan has a length smaller than that of the second wing. 3. The generator in accordance with claim 2, wherein each of the blades of the cooling fan has a breach formed between the first wing and the second wing. 4. The generator in accordance with claim 1, wherein each of the blades of the cooling fan is integrally formed with the first wing and the second wing. 5. The generator in accordance with claim 1, wherein each of the blades of the cooling fan has an arc-shaped concave oblique shape to form a wind shear oblique face. 6. The generator in accordance with claim 1, wherein the second side of the generator body is formed with an opening. 7. The generator in accordance with claim 6, wherein the first wing of each of the blades of the cooling fan is received in the opening of the generator body, and the second wing of each of the blades of the cooling fan is protruded outward from the opening of the generator body. 8. The generator in accordance with claim 1, wherein the first wing and the second wing of each of the blades of the cooling fan co-operate to carry air away from the generator body in a synchronous manner. 9. The generator in accordance with claim 1, wherein the first wing and the second wing of each of the blades of the cooling fan co-operate to carry the hot air away from the generator body rapidly, thereby enhancing the heat dissipation effect of the cooling fan. 10. A generator, comprising: a housing; an engine mounted in the housing; a generator body mounted in the housing and having a first side juxtaposed to the engine; a cooling fan rotatable mounted on an opened second side of the generator body and including a plurality of blades each having an inner side formed with a first wing located adjacent to the second side of the generator body and an outer side formed with a second wing spaced from the second side of the generator body; wherein the first side of the generator body is formed with a plurality of air intakes; wherein the air intakes of the generator body have changeable positions. 11. The generator in accordance with claim 1, further comprising a cooling fan mounted in the engine.
