A grill for an air conditioning unit has one or more grill members wrapped with wire so as to present a varying topographical surface to the flow of air over the grill members. The resulting grill member profile that is presented to the air flow reduces vortex shedding noise that would otherwise occur without the wire wrapping. Various wire wrappings are disclosed which produce the desired effect of reducing the vortex shedding noise. |
