Abstract
A carrier for a printed circuit board or card on which electronic components are mounted, the carrier making it possible to disperse an increased quantity of heat given off by the components in the direction of an energy dissipating frame with which the carrier is in contact. The carrier comprises two flat parallel metal plates of identical perimeter defining between them a space which is entirely closed along the perimeter, the space containing a porous metallic material in contact with the plates, and being partially filled by a liquid which evaporates at the working temperature of the carrier.
