第1の実施の形態の第1変形例に係るパワーモジュール装置10に適用可能なパワーモジュール100Aとしては、図5に示すように、放熱器42が、ヒートシンクとしても機能する取付部42aと、固着具104が挿通される貫通孔42bと、取付部42aの下面(裏面)側に段部42dを有して配置された複数本の冷却ピン(放熱ピン)42cと、Oリング用の溝部42eとを備える構成としても良い。
これに対し、比較例に係るパワーモジュール装置200は、図8(b)に示すように、取付部43aの非接合面に段部がないため、放熱器43の冷却ピン43cの基端部と開口部35における装着部31aの厚さとの段差により冷却水の流れが妨げられ、特に冷却ピン43cの基端部において、冷却水路33内を流れる冷却水が滞り易くなるために効率良く冷却できなくなり易い。
