Description
図1は、この発明に係る実施の形態1による電子機器の構成を示す斜視図である。図2は実施の形態1による冷却板の外観斜視図である。図3は実施の形態1による冷却板1の構造を示す断面図である。図4は実施の形態1による蓄熱材融解後の冷却板1の状態を示す断面図である。
冷却板1は、上下面に設置された発熱体2の発熱により温度が上昇する。その温度上昇に伴う熱は蓄熱材3に伝達し、蓄熱材3は融解温度に達する。融解した蓄熱材3は液化蓄熱材4に相変化し、構造体100内部の蓄熱材3の保持部22と気相部21の間に設けられた蓄熱材とおし穴5を通り抜け、図4に示すように気相部21に移動する。気相部21に移動した液化蓄熱材4の体積により、気相部21の内部圧力は増加する。液化蓄熱材4は、冷却板1の構造体100の側面に設けた内圧調整穴13をとおり、気相部21から気体が抜け出し、過大な圧力が構造体100に印加されることがなくなる。
Claims (2)
