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.

1. A flexible heat pipe comprising:a separator comprising at least one flexible layer with holes for multidirectional movement of vapor; wick layers in contact with and located on both sides of the separator, with the wick layers comprising flexible porous material; and two outer walls enclosing the separator and the wick layers, with the outer walls in contact with the surfaces of the wick layers which are opposite from the separator, the edges of the outer walls bonded together, and the outer walls comprising: first layer of metal foil; and a second layer of metal foil bonded to the first layer of metal foil wherein each metal foil layer is less than 0.010 inches thick.
