SPIRAL FAN ASSEMBLY

摘要

PURPOSE: A spiral fan assembly is provided to reduce the size of a blowing fan system having the spiral fan assembly by allowing the spiral fan assembly to generate a great amount of wind having great wind pressure without limiting an installation space of the spiral fan assembly. CONSTITUTION: A spiral fan assembly includes a rotating shaft(1) rotatably coupled to a driving motor, a cylindrical hub(2) fixedly coupled to the rotating shaft(1), a plurality of blades(3) formed at an outer peripheral portion of the cylindrical hub(2) in a spiral pattern, and a fan housing(4) surrounding a rotational route of the blades(3). Two blades(3) are installed in the outer peripheral portion of the cylindrical hub(2) with a spiral pattern at an 180degs interval. When a distance between the outer peripheral portion of the cylindrical hub(2) to a tip of the blade(3) is equal to a width of the blade(3), the width of the blade(3) is uniformly formed in the axial direction of the blade(3).
