Vapor chamber and method for manufacturing the same
A vapor chamber includes a sealed flattened casing containing working liquid therein, a wick structure arranged on an inner face of the casing, a supporting plate received in the casing and a plurality of supporting posts. The supporting plate defines a plurality of fixing holes therein. The supporting posts are engagingly received in the fixing holes of the supporting plate. Top and bottom ends of the supporting posts engage with the wick structure to reinforce a structure of the vapor chamber.
1. A vapor chamber comprising:
a sealed flattened casing containing working liquid therein;
a wick structure arranged on an inner face of the casing;
a supporting plate received in the casing and defining a plurality of fixing holes therein; and
a plurality of supporting posts engagingly received in the fixing holes of the supporting plate wherein a middle portion of each supporting post is interferingly fitted in a corresponding fixing hole in the supporting plate; and a plurality of vapor passages are defined in the supporting plate.
2. The vapor chamber of claim 1 , wherein the vapor passages are in a same configuration with the fixing holes and surround the supporting posts.
3. The vapor chamber of claim 1 , wherein the vapor passages are rectangular openings each having a size much large than that of each of the fixing holes.
4. The vapor chamber of claim 1 , wherein the supporting plate comprises a plurality of elongated members which are parallel and spaced from each other.
5. The vapor chamber of claim 1 , wherein each supporting post has a large end and a small end opposite to the large end, a diameter of each supporting post being gradually decreased from the large end to the small end.
6. The vapor chamber of claim 5 , wherein the supporting posts are inserted into the fixing holes from two different opposite sides of the supporting plate to make the large ends and small ends of the supporting posts located at different sides of the supporting plate.
7. The vapor chamber of claim 6 , wherein the supporting posts are arranged in plural columns and rows in the supporting plate.
8. The vapor chamber of claim 7 , wherein the large ends and the small ends of the supporting posts in a same column are alternately arranged at a same side of the supporting plate.
9. The vapor chamber of claim 1 , wherein the supporting posts are sandwiched between two portions of the wick structure arranged on two facing inner faces of the casing.
