Abstract
The present invention discloses a method of constructing a heat pipe that includes providing a heat pipe with phase change media therein and injection overmolding the heat pipe with a conductive composition. The thermally conductive composition absorbs or reflects electro magnetic interference waves and prevents their transmission into and through the heat pipe to the electronic components being cooled by the heat pipe.
