Benefits of technology
[0005]In accordance with one aspect, a bumper for a front end of a vehicle comprises a body having an opening defining an air flow inlet. The opening is elongated in the transverse direction of the body and is defined by spaced apart transverse walls and spaced apart side walls. A grille is disposed in the opening. The grille includes at least one generally horizontal member having at least one sound attenuating member attached thereto and configured to at least partially alter the air flow passing through the grille to mitigate resonance associated with the flow of air through the grill.
[0007]In accordance with yet another aspect, a grille for a bumper for a front end of a vehicle includes a plurality of horizontal members connected with a plurality of generally vertical members. The grille defines a plurality of air ports through which air passes through the grille. At least one sound attenuating member is connected with at least one of the horizontal members and vertical members and is configured to at least partially alter the air flow passing through the grille to mitigate resonance associated with the flow of air through the grille.
Problems solved by technology
These resonant vortices 180 can result in unwanted noises, such as a whistle sound, that is audible from the inside of the vehicle.

Description
BACKGROUND[0001]Exemplary embodiments herein generally relate to a cooling structure for a front end of a vehicle. More particularly, the present disclosure is directed to a grille for a vehicle bumper configured to attenuate aerodynamically induced noises and sounds from the flow of air through the grille.[0002]FIG. 1 is a perspective view of a vehicle 100 provided with a cooling structure 102. The vehicle 100 includes an engine compartment 110 provided at a front end of the body of the vehicle, a bumper 112 attached to a lower portion of the front end of the vehicle body and a grille 114 attached to an upper portion of the front end of the vehicle body. The bumper 112 has an elongated opening 116 formed in a central portion of a frontward protruding portion 118 of the front bumper 112, and the opening elongates in the transverse direction of the vehicle body. The opening 116 is defined by spaced transverse walls 120,120 and spaced apart side walls 122,122. A grille or mesh 128 is ...
