<P>PROBLEM TO BE SOLVED: To provide an axial fan capable of generating continuous air flow with little intensity change and a blower using the same. <P>SOLUTION: The axial fan has a short cylindrical shape frame 2 whose both ends in an axial direction are opened and a blade part 5 comprising a plurality of blades 10 arranged in the frame 2, a flowing through space P through which sub air flow Vs generated with the main air flow Vm generated by the blade part 5 flows is formed inside more than the inner end of the blades 10 constituting the blade part 5, thereby the sub air flow Vs flows so as to alleviate the intensity of the main air flow Vm, consequently continuous complex air flow Vc with little intensity change can be obtained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
