Description
図1は、この発明の実施の形態1に係る電子機器システムを示す構成図である。電子機器システムは、電子機器1と、電子機器1を冷却する全体冷却システム2とを備えている。電子機器1は、複数の電子機器ユニット101と、複数の電子機器ユニット101のそれぞれを冷却する複数の電子機器冷却システム102とを有している。全体冷却システム2は、複数の電子機器冷却システム102を介して、複数の電子機器ユニット101のそれぞれを冷却する。この例では、全体冷却システム2は、予め設定位置に設置されている。
図7は、この発明の実施の形態2に係る電子機器における配管を示す側面図である。配管103は、一対の内側配管部121と、一対の内側配管部121に接続された一対の内側配管延長部122と、一対の内側配管延長部122に接続された一対の外側配管部123とを備えている。内側配管部121および内側配管延長部122は、直線形状に延びて形成されている。外側配管部123は、U字形状に形成された湾曲配管部126と、内側配管延長部122と湾曲配管部126とを繋ぐ一対の可動配管部127とを有している。湾曲配管部126は、基板111の側面を跨ぐように配置される。可動配管部127は、外力が加えられていない場合には、内側配管部121および内側配管延長部122の延長線上に直線形状に延びて配置される。
図13は、この発明の実施の形態3に係る電子機器における配管を示す側面図である。変形可能な可動配管部が含まれる外側配管部123の形状は、コイル形状となっている。その他の構成は、実施の形態1または実施の形態2と同様である。
図14は、この発明の実施の形態4に係る電子機器の要部を示す正面図である。配管103は、複数の冷却器118のうちで2個離れた一対の冷却器118を互いに繋いでいる。言い換えれば、冷却器118によって繋がれた一対の冷却器118は、隣り合っていない。
