Abstract
A cooling fan module is provided. The cooling fan module may include a frame, a fan assembly, a number of guide vanes, and a cylindrical deflector. The frame may include a sidewall that defines an opening and an outer periphery. The fan assembly may be disposed within the opening and include fan blades extending from a hub and terminating at a fan ring. The fan ring may have a curved profile. The number of guide vanes may be disposed radially around the opening. The cylindrical deflector may extend axially from the sidewall and radially surround the number of guide vanes. The cylindrical deflector may be disposed radially between the number of guide vanes and the outer periphery.
Claims20
A cooling fan module comprising:
- a frame including a sidewall extending in a radial direction and defining an opening, and an outer peripheral wall;
- a fan assembly disposed within the opening and including fan blades extending from a hub and terminating at a fan ring, having a curved profile;
- a number of guide vanes disposed radially around the opening;
- a cylindrical deflector wall extending axially from the sidewall, radially surrounding the number of the guide vanes, and disposed radially between the number of guide vanes and the outer peripheral wall;
- and
- a planar annular ring, wherein each of the guide vanes of the number of guide vanes are disposed between the planar annular ring and the sidewall.
A cooling fan module comprising:
- a frame including a sidewall defining an outer periphery and a central opening that defines an inner periphery, wherein the outer periphery and the inner periphery each define an axially extending flange, the sidewall includes a first section and a second section disposed radially inward and radially aligned with respect to the first section, and the central opening is radially aligned with the sidewall;
- a fan assembly disposed within the opening and including fan blades that terminate at a fan ring that at least partially overlaps the inner periphery in a radial direction;
- a cylindrical sleeve axially extending from a surface of the sidewall and disposed between the first and second sections;
- and
- a number of guide vanes arranged circumferentially about the inner periphery and radially inward from the sleeve.
A cooling fan module for comprising:
- a frame defining an outer periphery, wherein the frame further defines a central opening that defines an inner periphery;
- a fan assembly disposed within the central opening and including a fan ring, wherein the fan ring includes a concave surface that at least partially surrounds the inner periphery;
- a number of guide vanes arranged circumferentially about the inner periphery;
- an annular deflector wall extending axially from a surface disposed radially between the outer periphery and the number of guide vanes;
- and
- a planar annular ring wherein the planar annular ring is coupled to the annular deflector wall and configured to mitigate noise associated with recirculation of air through the fan assembly.
