Abstract
The cooling fan module may include a fan assembly and a fan shroud. The fan shroud of the cooling fan module may include a first sidewall that may extend in a radial direction and define an opening. The fan assembly may include a hub disposed within the opening, a blade extending from the hub to a distal end that may include a first side and a second side converging to form a first leading edge with respect to the rotational direction. The fan assembly may include a winglet that may include a first fin, extending in the axial direction from the distal end of the blade and a second fin extending in the radial direction.
Claims17
A fan assembly, rotatable in a rotational direction about a rotational axis, for use in a vehicle cooling fan module including a fan shroud provided with a first sidewall extending in a radial direction defining an opening, the fan assembly comprising:
- a hub disposed within the opening;
- a blade extending from the hub to a distal end and including a first side and a second side converging to form a first leading edge with respect to the rotational direction;
- and
- a winglet including a first fin, extending in an axial direction from the distal end so that portions of the first fin are disposed on the first side and the second side of the blade, and a second fin extending in the radial direction, wherein the second fin includes a second leading edge and a trailing edge, each arranged with respect to the rotational direction, and a distal edge extending therebetween, wherein the second leading edge extends along a first angle oblique to a radial line extending from the rotational axis, and wherein the distal end of the blade includes a first portion and a second portion formed by a substantially planar surface extending between the first fin and the first leading edge and defining a second angle with respect to the radial line, wherein the second angle is substantially perpendicular to the radial line.
A cooling fan module comprising:
- a frame provided with a first sidewall extending in a radial direction and defining a central opening;
- and
- a fan assembly disposed within the central opening and including,
- a hub,
- a blade extending from the hub to a distal end and including a first side and a second side converging to form a first leading edge, and
- a winglet including a first fin, extending in an axial direction from the distal end so that portions of the first fin are disposed on the first side and the second side of the blade, and a second fin extending in the radial direction, the first fin having a first corner and a second corner that is diagonal to the first corner, wherein the blade extends from the first corner to the second corner.
A fan assembly, rotatable in a rotational direction about a rotational axis, for use in a vehicle cooling fan module including a fan shroud provided with a first sidewall extending in a radial direction defining an opening, the fan assembly comprising:
- a hub disposed within the opening;
- a blade extending from the hub to a distal end and including a first side and a second side converging to form a first leading edge with respect to the rotational direction;
- and
- a winglet including a first fin, extending in an axial direction and a second fin extending in the radial direction, wherein the first fin includes a second leading edge with respect to the rotational direction and a portion of the first leading edge, disposed at the distal end of the blade, extends beyond the second leading edge of the first fin, wherein the portion of the first leading edge lies within a common plane defined by a surface of the first fin.
