Abstract
【解決手段】半導体素子の冷却構造は、半導体素子1と、半導体素子1が搭載されるヒートシンク2と、半導体素子1に対してヒートシンク2の反対側に位置するように半導体素子1に取付けられ、ケース31および潜熱蓄熱材32を含む蓄熱部材3とを備える。
【選択図】図2
Description
図4に示す変形例では、蓄熱部材3のケース31の表面にディンプル33が形成されている。半導体素子1が発熱した際、蓄熱部材3と半導体素子1との線膨張係数の差により、蓄熱部材3に応力が生じる場合がある。また、潜熱蓄熱材32が相変化する際、その体積が変化することにより蓄熱部材3に応力が生じる場合がある。これに対し、上記のようにディンプル33が設けられることにより、蓄熱部材3に生じた応力が緩和される。
