1. A flexible vapor chamber, comprising two flexible enclosures and a wick structure, wherein each of the flexible enclosures is a flat and thin structure having a width and a length; each of the flexible enclosures is opposed to each other in a thickness direction, and each of the flexible enclosures is combined to form a sealing edge structure, and a chamber is formed between each of the flexible enclosures and the sealing edge structure; the interior of the chamber accommodates a working fluid, which is used to absorb and dissipate heat, and the wick structure is disposed in the chamber and divides the chamber to form multiple wick spaces which are used to direct the flow direction of the working fluid;
each of the flexible enclosures is a layered structure that is flexibly bent in the thickness direction, and each of the flexible enclosures comprises a first metal film, a flexible polymer film, and two second metal films, wherein the first metal film is positioned on a side of each of the flexible enclosures facing the chamber in the thickness direction, and each of the second metal films is positioned on a side of each of the flexible enclosures away from the chamber in the thickness direction, and the polymer film is positioned between the first metal film and the second metal film;
the flexible enclosure is formed with a flexible section and two extensions along a length direction, wherein each of the flexible sections is located between each of the extensions that constitute each of the flexible enclosures, and each of the flexible sections extends to opposite sides of each of the flexible enclosures in a width direction; the thickness of each of the flexible sections is thinner than the thickness of its adjacent connected extensions, whereby each of the flexible enclosures is flexibly bent in the thickness direction;
the configuration density of the wick structure at the part corresponding to each of the flexible sections is smaller than the configuration density at the part corresponding to each of the extensions.
