Fan shroud and seal ring assembly, and method thereof

摘要

A fan shroud and seal ring are assembled together to allow a condenser, radiator, and fan module (CRFM) to be vertically loaded into an engine compartment of a vehicle to be mounted to the vehicle chassis and engine with a fan stator. The fan shroud has a plurality of first attachment components, and the seal ring has a plurality of second attachment components, each of which corresponds to a first attachment component. Each first attachment component engages with a corresponding second attachment component to secure the seal ring to the fan shroud, such that the seal ring is positioned around at least a portion of the fan stator after the CRFM has been mounted and the assembly is in its final configuration.

1. A fan shroud and seal ring assembly to allow vertical loading of a condenser, radiator, and fan module (CRFM) into an engine compartment of a vehicle to be mounted to a vehicle chassis and engine with a fan stator, the assembly comprising:
a fan shroud having:
a shroud body;a shroud flange extending from the shroud body;a fan opening in which the fan module of the CRFM sits, the fan opening having a border defined by the shroud flange; anda plurality of retention slots; and a seal ring including a base component having a shape that substantially corresponds with the shape of at least a portion of the border of the fan opening, the seal ring having a plurality of retention tabs, the base component having an inner base surface and an outer base surface opposite the inner base surface, and the base component having a front base surface and a rear base surface opposite the front base surface, the front base surface extending between the outer base surface and the inner base surface, and the rear base surface extending between the outer base surface and the inner base surface; wherein the seal ring includes at least one retention flange coupled to the base component, the at least one retention flange is spaced radially outward relative to the outer base surface of the base component such that the at least one retention flange and the outer base surface jointly define a channel therebetween, and the shroud flange is sized to be received within the channel; wherein the seal ring is movably coupled to the fan shroud such that the seal ring is movable relative to the fan shroud between a retracted position and an extended position, and the rear base surface is closer to the shroud body when the seal ring is in the retracted position than when the seal ring is in the extended position; wherein the shroud flange is disposed within the channel when the seal ring is in the retracted position, such that the seal ring is attached to the fan shroud when the seal ring is in the retracted position; and wherein the retention tabs engage with the corresponding retention slots to align and attach the seal ring to the fan shroud such that the seal ring is positioned around at least a portion of the fan stator when the seal ring is the extended position.
