    摘要： A heat sink fan of the present invention includes a heat sink and a fan. The heat sink includes a base having a center axis and a plurality of fins extending radially outwardly from an outer circumference of the base and disposed in a circumferential direction. The fan includes an impeller portion disposed adjacently to the heat sink in the direction along the center axis, the impeller portion rotating about the center axis, and a frame portion for covering and fixing the impeller portion, part of the frame portion being opposed to the heat sink. The frame portion has at least one protruding portion. The protruding portion enters into a space between the fins which are adjacent to each other.

    摘要： An impeller in a centrifugal fan includes a support portion having a cylindrical outer circumferential surface coaxial or substantially coaxial with a center axis and a plurality of moving blades arranged on the outer circumferential surface of the support portion independently of one another and configured to draw an air along the center axis and expel the air radially outwards when rotated about the center axis together with the support portion. At least one of the moving blades includes a first blade portion connected to, and extending radially outwards from, the outer circumferential surface of the support portion, at least one second blade portion having a radial inner end portion radially spaced apart from the outer circumferential surface of the support portion and a connecting member arranged to interconnect the first blade portion and the second blade portion.
