1. A cowling comprising: a cover body having an accommodating space, a first opening communicated to the accommodating space, and a second opening communicated to the accommodating space and opposite to the first opening;an impeller disposed in the accommodating space;a shaft passing through the impeller and the cover body;at least two connecting parts extended from the cover body; andan empennage connected to the cover body through the connecting parts and facing to the second opening, wherein the empennage is planar, and the empennage and the shaft are located on a same plane,wherein the first opening extends outwardly from the cover body and includes an outer peripheral surface, a plurality of air-guiding elements are installed within the first opening along a longitudinal direction of the cover body to divide the first opening into a plurality of air inlets, each of the plurality of air-guiding elements having an outer side surface and an inner side surface, and the outer peripheral surface of the first opening is flush with the outer side surfaces of the plurality of air-guiding elements,wherein the first opening asymmetrically faces one side of the impeller relative to the shaft. 2. The cowling as claimed in claim 1, wherein the connecting part comprises the empennage having a circle, rhombus, polygon, T, fin or other shape. 3. The cowling as claimed in claim 1, further comprising a bearing for supporting the shaft. 4. The cowling as claimed in claim 1, wherein the first opening is located at one side of the cover body and correspondingly faces the impeller. 5. The cowling as claimed in claim 1, wherein the first opening is an air inlet and the second opening is an air outlet. 6. The cowling as claimed in claim 1, wherein the first opening is a bell shape or a rectangle. 7. A cowling for a wind power generator, comprising: a cover body having: a first opening; and a second opening;an accommodating space communicated to the first opening and the second opening;an impeller disposed in the accommodating space;a shaft passing through the impeller and the cover body; andan empennage connected to the cover body by at least two connecting parts,wherein the second opening communicated to the accommodating space and opposite to the first opening; andwherein the empennage is kept out of the second opening, the empennage is planar, and the empennage and the shaft are located on a same plane, andwherein the first opening extends outwardly from the cover body and includes an outer peripheral surface, a plurality of air-guiding elements are installed within the first opening along a longitudinal direction of the cover body to divide the first opening into a plurality of air inlets, each of the plurality of air-guiding elements having an outer side surface and an inner side surface, and the outer peripheral surface of the first opening is flush with the outer side surfaces of the plurality of air-guiding elements,wherein the first opening asymmetrically faces one side of the impeller relative to the shaft. 8. The cowling as claimed in claim 7, wherein the connecting part comprises an empennage having a circle shape, rhombus shape, polygon shape, T shape, fin shape or other shapes. 9. The cowling as claimed in claim 7, further comprising a bearing for supporting the shaft. 10. The cowling as claimed in claim 7, wherein the first opening is a bell shape or a rectangle. 11. The cowling as claimed in claim 7, wherein the first opening is an air inlet and the second opening is an air outlet. 12. A cowling comprising: a cover body having an accommodating space;an impeller disposed in the accommodating space;a shaft passing through the impeller and the cover body;two bearings disposed at the two ends of the shaft, respectively;two openings communicated to the accommodating space and disposed opposite each other; andan empennage connected to the cover body by at least two connecting parts and kept out of one of the two openings, wherein the empennage is planar, and the empennage and the shaft are located on a same plane,wherein the other one of the two openings extends outwardly from the cover body and includes an outer peripheral surface, a plurality of air-guiding elements are installed within the other one of the two openings along a longitudinal direction of the cover body to divide the other one of the two openings into a plurality of air inlets, each of a plurality of air-guiding elements having an outer side surface and an inner side surface, and the outer peripheral surface of the other one of the two openings is flush with the outer side surfaces of the plurality of air-guiding elements,wherein the first opening asymmetrically faces one side of the impeller relative to the shaft.
