Abstract
To provide a vapor chamber having excellent function of circulating a working liquid from an end portion to a center portion of a wick and enabling the prevention of the occurrence of dry-out. A vapor chamber includes a casing formed of a first sheet and a second sheet which face each other and whose outer peripheries are bonded to each other; a working liquid sealed in the casing; and a wick disposed on an inner wall surface of the first sheet or the second sheet. A wall portion is disposed around the wick as viewed in a top plan view of an inside of the casing.
Claims12
A vapor chamber comprising:
- a casing comprising:
- a first sheet having a first inner sheet surface, and a second sheet having a second inner sheet surface, the first inner sheet surface of the first sheet and the second inner sheet surface of the second sheet face each other, wherein the first sheet and the second sheet are bonded and sealed to each other at the outer edges to form a cavity;
- a working liquid sealed in the casing within the cavity, the working liquid comprising a fluorocarbon;
- and
- a nonwoven mesh having a plurality of apertures that is disposed on the first inner sheet surface of the first sheet within the cavity, wherein the apertures have a size of 0.10 μm to 50.
