Description
図1は、本発明の第1の実施形態である車載制御装置の断面図である。図1の発熱電子部品周りの局所構造を抽出したのが図4である。本発明に係る構成として、図4の(A)、(B)、(C)が可能である。図4(A)は、放熱金属ベース10の発熱電子部品42下部に相当する領域に凹み部を設け、ここに放熱材50を配置した構成である。図4(B)は、図4(A)の凹み部周囲に突起部を設けた構成である。図4(C)は、図4(B)の凹み部を無くし、突起部を残したものである。
本実施例は、第一の実施形態の放熱金属ベース突起部を図10(B)(C)(D)の形状にした場合である。放熱金属ベース突起部の高さは、図6に示すように各種のものが適用可能であり、それぞれで期待できる効果の内容に違いが生じる。図6(A)では第一の実施形態で記載した効果があり、図6(B)が本実施例の場合である。図6(B)の構成で樹脂封止した場合の実施形態である車載制御装置の断面図を図2に示す。突起部高さが高いため放熱材50を多く充填可能で、放熱材50を発熱電子部品リード部も覆うように配置できるため、放熱効果を一層高めることが可能である。
本実施例は、第一の実施形態の放熱金属ベース突起部を図11(B−1)の形状にした場合である。放熱金属ベース突起部の高さは、図6に示すように各種のものが適用可能であり、それぞれで期待できる効果に違いが生じる。図6(A)では第一の実施形態で記載した、放熱材節約・保護の効果があり、図6(B)では第二の実施形態で記載した、放熱材節約・保護に加え、狭い隙間への樹脂充填性確保の効果があり、図6(C)が本実施例の場合である。
本実施例は、放熱金属ベースの突起部を放熱ベースと別部材にしたものである。上記第一〜第三の実施例の何れにも適用可能である。突起部の材質としては、放熱金属ベースと同じ材料、別の金属材料、樹脂材料、ガラスやセラミックスなど無機材料などから選択することができる。予め上記材料で突起構造体を形成し、これを放熱金属ベースの該当する位置に固定する。固定手段としては、接着、溶着、摩擦接合など含め、適宜手法を選択する。また、ペースト状の材料をディスペンス手法などで放熱金属ベースの所定の位置に突起形状を形成してから硬化あるいは固化させてもよい。
