Summary:To provide a vapor chamber capable of increasing a heat transport capacity even when it has a flow channel where directions change.SOLUTION: A vapor chamber includes, in a sealed space, condensed liquid flow channels, which are flow channels where working fluid moves in a state of a condensed liquid, and a plurality of vapor flow channels where the working fluid moves in a state of a vapor and a condensed liquid, whose flow channel cross sectional area is larger than that of the condensed liquid flow channel. The plurality of condensed liquid flow channels and the plurality of vapor flow channels include linear sections that extend linearly, and curved sections continued to the linear sections, where the directions that the plurality of condensed liquid flow channels and the plurality of vapor flow channels extend change. The vapor flow channels in the curved sections are configured so that their flow channel cross sectional area is larger than that of the vapor flow channels in the linear sections.SELECTED DRAWING: Figure 21 【課題】方向が変化する流路を有する場合であっても熱輸送能力を高めることができるベーパーチャンバーを提供する。【解決手段】密閉空間に、作動流体が凝縮液の状態で移動する流路である凝縮液流路と、凝縮液流路より流路断面積が大きく、作動流体が蒸気及び凝縮液の状態で移動する複数の蒸気流路と、が備えられており、複数の凝縮液流路と複数の蒸気流路が直線状に延びる直線部と、直線部に連続し、複数の凝縮液流路と複数の蒸気流路の延びる方向が変化する湾曲部と、を有し、湾曲部における蒸気流路は、直線部における蒸気流路よりも流路断面積が大きくなるように構成されている。【選択図】図２１
