  • Patent number: 11143196
    Abstract: Embodiments of the present disclosure are directed to an inline centrifugal mixed flow fan system that includes a wheel assembly disposed within an outer housing and comprising a hub cone, a plurality of fan blades directly coupled to and extending radially outward from the hub cone, and a shroud directly coupled to and at least partially radially surrounding the plurality of fan blades. The wheel assembly is configured to receive an air flow at an inlet axial end of the outer housing axially upstream of the wheel assembly, and to redirect the air flow axially downstream relative to a central longitudinal axis, circumferentially about the central longitudinal axis, and radially outward from the central longitudinal axis.

  • Publication number: 20210123454
    Abstract: A blade (112) includes an upper surface and a lower surface, the upper surface being a pressure face (212), and the lower surface being a suction face (214), a blade tip (216) and a blade base (218), a leading edge (222) and a trailing edge (220), where the pressure face (212) and the suction face (214) each extend from the blade tip (216) to the blade base (218), and each extend from the leading edge (222) to the trailing edge (220). The blade (112) further includes a bent part (262), the bent part (262) being arched from the pressure face (212) toward the suction face (214), where the bent part (262) has a lowest point in a radial cross section of the blade (112), and a connecting line (252) of the lowest points extends in a direction from the leading edge (222) to the trailing edge (220).

  • Publication number: 20200340494
    Abstract: A centrifugal blower has a first housing section and a second housing section separated by a width of the centrifugal blower. The centrifugal blower also has an intake port extending through the first housing section and the second housing section along the width, and an outlet port formed by the first housing section and the second housing section. A dimension of the width continuously decreases as the outlet port is approached along a length of the centrifugal blower.
