Abstract
A vapor chamber excellent in productivity, reduction of a number of components, and capable of preventing reduction in area of a cavity section while reducing a space of an outer periphery of the cavity section in which a working fluid is sealed is provided. An example vapor chamber has a container in which a cavity section is formed by stacked plate-shaped members, a working fluid that is sealed in the cavity section, and a wick structure accommodated in the cavity section.
Claims18
A vapor chamber comprising:
- a container in which a cavity section is formed by stacked plate-shaped members;
- a working fluid that is sealed in the cavity section;
- and
- a wick structure accommodated in the cavity section,
- wherein a first plate-shaped member on a first side of the container, forming a first outermost layer of the container, has at least one projecting portion having a first hole portion,
- wherein a second plate-shaped member on a second side of the container, forming a second outermost layer of the container opposite of the first outermost layer, has at least one projecting portion that is stacked on the projecting portion of the first plate-shaped member, and includes a flow path that allows the first hole portion and the cavity section to communicate with each other,
- wherein an outer periphery of the cavity section is sealed, and
- wherein a third plate-shaped member forming a middle layer is stacked between the first plate-shaped member on the first side forming the first outermost layer and the second plate-shaped member on the second side forming the second outermost layer, wherein the third plate-shaped member has at least one projecting portion that overlaps with the projecting portion of the first plate-shaped member and the projecting portion of the second plate-shaped member, wherein the third plate-shaped member includes a second hole portion communicating with the first hole portion and the flow path, and the third plate-shaped member further includes a frame portion forming an inner side surface of the cavity section.
