Document Type and Number:
Japanese Patent JP7464097
Kind Code:
B2
Abstract:
To provide a vapor chamber capable of suppressing deformation even when being thinned.SOLUTION: A vapor chamber has a sealed space formed between a plurality of sheets, in which a working fluid is enclosed in the sealed space. The sealed space is provided with a condensate flow passage in which the working fluid moves in a condensate state, and a vapor flow passage that is larger in flow passage cross sectional area and in which the working fluid moves in a state of vapor and condensate. At least one of the plurality of sheets has an inner layer forming the sealed space, and an outer layer that is disposed on the opposite side of the sealed space from the inner layer. The upper yield point or 0.2% proof stress of the material constituting the outer layer is greater than the upper yield point or 0.2% proof stress of the material constituting the inner layer.SELECTED DRAWING: Figure 3
