A plate fin heat transfer device utilizes titanium plate members and aluminum dividers. The solid bar may be titanium, aluminum or an alloy of either. The titanium plate members may have a thermal conductivity of approximately 50 or 100 BTU/Hr/ft/F/in and dramatically reduce matrix conduction of heat within the plate members. The plate members may be as thin as approximately 0.002 inches while providing the necessary strength to avoid leakage during or after the manufacturing process. The advantageous thinness satisfies weight and volume parameters critical to an aircraft.
