Abstract

The invention is a very flexible heat pipe which is constructed of multiple layers of material laminated into the final structure. The center of the symmetrical structure is a coarse screen which creates a vapor space. The layers on either side of the screen are copper felt pads, and the outer casing is two layers of metal foil and a layer of polypropylene. The heat pipe constructed in this manner is so a flexible that when one outside surface is covered with adhesive, the heat pipe can essentially be used as tape or a stick-on heat transfer surface which conforms to a body being cooled.
