  • IMPELLER AND FAN ASSEMBLY
    Publication number: 20250084866
    Abstract: An impeller includes a hub having an axial direction as a rotation axis and extending from a first end to a second end, and including an end surface and a first wall. The end surface is positioned at the first end of the hub, one end of the first wall extends around an entire periphery of the end surface and radially outwardly extends at an angle toward the second end in the axial direction. A length of extension of the first wall is greater than 50% of a length of extension of the hub. The impeller further includes a plurality of blades, the proximal ends of which extend from the periphery of the hub in a radial direction. A predetermined range of angle is formed between the first wall and the axial direction, and the predetermined range of angle is between 3 degrees and 45 degrees.
