Abstract
A serpentine continuous vapor passage is formed in a metal card which mounts electronic components. Elongated channels of the passage evaporate the contained liquid in response to conducted heat from mounted electronic components. By mounting the side edges of the card to heat conductive retaining means, the evaporated fluid becomes condensed at end sections of the passage thereby transferring the heat from the card and converting the evaporated liquid in a gaseous state back to a liquid state. The resultant card is gravity-insensitive and a thermal-resistance path is minimized so that the cooling capability of the card becomes maximized.
