Abstract
The fan assembly provided with a fan ring, including a first leg and a second leg, may be arranged with a shroud that may include a first sidewall, a second sidewall, a third sidewall, a first ring, a second ring, and a third ring. An air passage may be formed between a distal end of the first leg and the third ring, the second ring and the first leg, the second leg and the second sidewall, and a distal end of the first leg and the first ring. The air passage may be configured to improve acoustic performance and air flow efficiency.
Claims20
A cooling fan module comprising:
- a fan assembly including fan blades extending from a hub and terminating at a fan ring, wherein the fan ring includes a first leg, extending in an axial direction, a second leg, extending substantially orthogonally to the first leg, and a curved portion extending therebetween;
- and
- a shroud having an upstream side and a downstream side, wherein the fan assembly is arranged to move air from the upstream side to the downstream side, wherein the shroud includes,
- a first sidewall defining an opening,
- a first ring, a second ring, and a third ring each extending in an axial direction away from the upstream side, wherein the first ring extends from the first sidewall, wherein the first, second, and third rings are concentric with each other,
- a second sidewall extending between the first ring and the second ring, and
- a third sidewall extending between the second ring and the third ring,
- wherein the fan assembly is arranged with respect to the shroud such that the first leg is concentric to the second ring and the second leg is axially spaced apart from the second sidewall.
A cooling fan module for use in a vehicle comprising:
- a fan assembly including fan blades extending from a hub and terminating at a fan ring, wherein the fan ring includes a first leg, extending in an axial direction, a second leg, extending substantially orthogonally to the first leg, and a curved portion extending therebetween;
- and
- a shroud including,
- a first sidewall defining an opening,
- a first ring axially extending from the first sidewall,
- a second ring extending in the axial direction,
- a third ring extending in the axial direction, wherein the first, second, and third rings are concentric with each other arranged concentrically with respect to the second ring,
- a second sidewall extending between the first ring and the second ring, and
- a third sidewall extending between the second ring and the third ring;
- and
- wherein the second leg of the fan ring is spaced apart from the second sidewall by a first axial distance, wherein a distal end of the first leg is spaced apart from the third sidewall by a second axial distance, wherein the first axial distance is substantially equal to the second axial distance.
A cooling fan module for use in a vehicle comprising:

- and
- a shroud including,
- a first sidewall defining an opening,
- a first ring extending from the first sidewall in an axial direction,
- a second ring extending in the axial direction,
- a third ring extending in the axial direction and arranged concentrically with respect to the second ring,
- a second sidewall extending between the first ring and the second ring, and
- a third sidewall extending between the second ring and the third ring;
- and
- wherein an outer portion of the first leg is radially offset from an inner portion of the third ring.
