Embodiment 1
[0042] An embodiment of the present invention provides a centrifugal fan. figure 1 is a schematic diagram of the centrifugal fan 100 according to the embodiment of the present invention, showing the situation when the centrifugal fan 100 is observed along the section of the central axis OO'.
[0043] Such as figure 1 As shown, the centrifugal fan 100 includes:
[0044] The motor part 101 has a center axis OO' extending in the vertical direction as a center of rotation,
[0045] the cup part 102, which accommodates the motor part 101,
[0046] a plurality of vanes 103 arranged radially outside the cup portion 101,
[0047] the motor support part 104, which supports the motor part 101,
[0048] a ring portion 105, which is connected to the plurality of blades 103 on the outermost radial side of the plurality of blades 103,
[0049] Wherein, each blade 103 has an upper blade portion 1031 located on the axially upper side of the ring portion 105 and a lower blade portion 1032...
Embodiment 2
[0083] An embodiment of the present invention also provides a cooling device, which has the centrifugal fan described in Embodiment 1. The centrifugal fan 100 has been described in Embodiment 1, and its content is incorporated here and will not be repeated here. In addition, the cooling device has other conventional components. This embodiment does not limit the structure, arrangement and function of the conventional components, and reference may be made to the prior art.
[0084]In this embodiment, based on the centrifugal fan of Embodiment 1, each blade of the centrifugal fan has an upper blade portion located on the axially upper side of the ring portion and a lower blade portion located on the axially lower side of the ring portion, which can Expand the area of the blades of the centrifugal fan; thus, the gas can be fully sent out, so that not only the efficiency of the centrifugal fan can be improved, but also the air supply volume can be increased.
