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.

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).
