This invention relates to a vapor chamber (100) comprising a first thermally conductive plate (110) and a second thermally conductive plate (120) separated from each other by a plurality of bridging elements (140) to form a cavity (130) having a first height, H1 (001). The vapor chamber (100) comprises a bending section (151) and a non-bending section (152). The bending section (151) is configured to provide a bend having a first volume fraction (V1) of bridging elements (140), and the non-bending section (152) having a second volume fraction (V2) of bridging elements (140). A ratio of the first volume fraction (V1) and the second volume fraction (V2) is less than 0.7.
