PURPOSE:To improve the flow speed distribution of a fluid by allowing a belt which is extended to intersect and pass a fluid passage between a drive shaft and a tension shaft to support vanes at a predetermined interval. CONSTITUTION:A drive shaft 10 and a tension shaft 9 having a diameter which is larger than that of said drive shaft 10, and disposed mutually in parallel to each other within a main body case 5. The belt 11 travels toward a direction shown by a feathered arrow between the drive shaft 10 and the tension shaft 9 like an endless track, and a large number of two-dimensional vanes 12 supported on the belt 11 at a predetermined interval intersect and pass an air passage leading from an air suction port 6 to an air exhaust port 7. Upon this occasion, the two-dimensional vanes 12 suck up air in the course of travel in the proximity of an outdoor heat exchanger 1, and sucked air is exhausted in the traveling direction of the belt 11 in the course of traveling of the two-dimensional vanes 12 slantly on the opposite side of the outdoor heat exchanger 1. Thus, external air flows into a main body case 5 from the air suction port 6 as shown by an arrow, and is heat exchanged in the course of passing through the outdoor heat exchanger 1, and then is smoothly exhausted out of the air exhaust port 7 along a wall 8. |
