Latest Patents

Among his latest patents is the "Closed loop feedback control variable conductance heat pipe." This invention features a variable conductance heat pipe that includes an electronic component mounting plate serving as the evaporator. The evaporator connects to an air-cooled condenser, which condenses vapor flowing from the evaporator. The design incorporates a sump located at the lowest gravity point of the evaporator passage, ensuring a continuously wetted condition that accommodates heat dissipation transients. A control loop is established to manage the penetration of an inert gas into the heat pipe condenser, maintaining a constant temperature for the electronic components.

Another significant patent is the "Vapor chamber cooled electronic circuit card." This innovation involves a serpentine continuous vapor passage formed in a metal card that mounts electronic components. The elongated channels of the passage evaporate the contained liquid in response to heat from the components. By mounting the card's side edges to heat conductive retaining means, the evaporated fluid condenses at the end sections of the passage, effectively transferring heat and converting the vapor back to liquid. This design minimizes thermal resistance and maximizes the cooling capability of the card.
