Sound-attenuating heat exchangers and methods of utilizing the same are disclosed herein. The sound-attenuating heat exchangers include an aerodynamically shaped layer, a base, an intermediate layer, and a cooled fluid containment body. The aerodynamically shaped layer defines an aerodynamically shaped surface, an opposed intermediate layer-facing surface, and a plurality of apertures. The intermediate layer defines a shaped layer-facing surface and an opposed base-facing surface. The base defines a base surface. The intermediate layer-facing surface at least partially defines a sound-attenuating volume. The base surface at least partially defines an elongate cooling conduit. The sound-attenuating volume is distinct from the elongate cooling conduit and the intermediate layer at least partially fluidly isolates the sound-attenuating volume from the elongate cooling conduit. The cooled fluid containment body at least partially defines a cooled fluid containment conduit. The methods include methods of utilizing the sound-attenuating heat exchangers.
