  • Low drag skin heat exchanger
    Patent number: 10059435
    Abstract: A heat exchanger including a heat exchange panel having an exterior surface that forms an exterior surface portion of the vehicle (e.g. an aircraft), and including one or more vortex generators protruding from the exterior surface. The heat exchange panel has at least a portion made of a thermally conductive material. The one or more vortex generators are configured to direct airflow to particular areas on the aircraft, which may then prevent large scale airflow separation to synergistically enhance heat removal from the heat exchange panel and reduce drag of air flowing over the exterior surface.

  • LOW DRAG SKIN HEAT EXCHANGER
    Publication number: 20160159466
    Abstract: The present invention provides a heat exchanger including a heat exchange panel configured to form an exterior surface of the vehicle (e.g. an aircraft), the heat exchange panel having at least a portion made of a thermally conductive material, and one or more vortex generators protruding from the exterior surface and configured to direct airflow to particular areas on the aircraft, which may then prevent large scale airflow separation. The vortex generator also improves the surface mixing of air flowing over the exterior surface of the heat exchange panel.
