Abstract: A vapor chamber with an insertable wick system comprises two Coverskins and a Frame, where the insertable wick system provides at least a portion of a condensate flow path from the condensing surface to an evaporation region. The Coverskins are joined to the frame to form a “drum” enclosure whereby, similar to membranes on a drum, the two Coverskins resist deformation mainly through tensile forces along the plane of the skins, and thus much thinner materials could be used. The frame operates similar to the cylindrical body of a drum in providing the necessary bending resistance so as to keep the Coverskins in a state of relative tension when it is subject to external loading. The net result of this arrangement is that each component would largely be responsible for only one type of force (i.e., tension or bending), and thus a state of maximum efficiency could be achieved.
