Vapor chamber and method for manufacturing the same
View Patent ↗A vapor chamber includes a sealed flattened casing containing working liquid therein, a wick structure arranged on an inner face of the casing, a plurality of supporting posts received in the casing and at least a metallic wire connecting the supporting posts. Each supporting post defines at least a channel therein. The at least a metallic wire engagingly extends through the channels of the supporting posts. Top and bottom ends of the supporting posts engage 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 plurality of supporting posts received in the casing and each post containing at least a channel, top and bottom faces of the supporting posts engaging the wick structure;
at least a metallic wire engagingly passing through the channels of the supporting posts to interconnect the supporting posts;
wherein the supporting posts are arranged in a matrix, each of the supporting posts defining two channels along two opposite ends thereof, a plurality of metallic wires being interferingly pressed in the channels of the supporting posts; and
wherein the metallic wires pressed in the channels of the supporting posts are perpendicular to each other to form a grid-shape structure, spaces in the grid of the metallic wires acting as vapor passages for vaporized working liquid flowing therethrough during working of the vapor chamber.
2. The vapor chamber of claim 1 , wherein the two channels of each of the supporting posts are perpendicular to each other.
3. The vapor chamber of claim 1 , wherein the metallic wires fitted in the channels in the same ends of the supporting posts are parallel to each other.
4. The vapor chamber of claim 3 , wherein two metallic wires connected with one of the supporting posts are located at different planes.
5. The vapor chamber of claim 3 , wherein the metallic wires pressed in the channels in the two opposite ends of the supporting posts are distributed in two planes parallel to each other.
6. The vapor chamber of claim 1 , wherein the supporting posts are formed by molding and sintering metal powder.
7. The vapor chamber of claim 1 , wherein each supporting posts has a configuration of a cylinder.
8. The vapor chamber of claim 1 , wherein the top faces of the supporting posts are located at a same plane, the bottom faces of the supporting posts are located at another same plane, and the supporting posts are sandwiched between two facing portions of the wick structure arranged on the inner face of the casing.
