DAHLGREN, Va. - Naval Surface Warfare Center Dahlgren Division (NSWCDD) engineers Steven Price, left, and Andrew Wagner were recognized by NSWCDD leadership with the Patent Award in the command’s virtual honor awards ceremony, July 27. Price and Wagner are the recipients of a patent awarded by the U.S. Patent and Trademark Office for the capillary heat exchanger. Potential applications include the venting of air on naval vessels. It could be used to exchange stale air from inside a ship with outside air without losing the cooling in warmer climates, or the heat in cooler climates. The invention – a honeycomb-like device – can also be used as a heat exchanger to cool engines or other equipment that faces extreme temperatures. (U.S. Navy photo/Released)
