A noise suppressor for a heat exchanger comprises an air duct having a larger inlet than outlet encompassing the cooling fan to provide an antiresonant space to incoming air. The noise suppressor effectively reduces the noise level emanating from supplementary air-cooled transformers mounted on electric locomotive undercarriages.
