Description
本発明の一態様に係る電子機器は、筐体と、該筐体内に設置され、該筐体に形成された排気口に向けて送風するファンと、該ファンの送風出口に設けられた放熱部と、該放熱部に対して固定されたヒートパイプとを備え、前記放熱部は、前記ヒートパイプが接触している領域では、複数のフィン部材同士を部分的に固定して互いに接続した部分接続構造とされ、かつ、前記ヒートパイプが接触していない領域では、連続的なフィンとされた連続構造とされている。
図4に示したように、放熱フィン35,36は、ヒートパイプ73が接触している領域Aでは、各フィン部材60をヒートパイプ73に対して固定させることができるので、各フィン部材60同士を部分的に固定することで有効に放熱できる領域を形成することができる。したがって、ヒートパイプ73と直接接触している領域Aでは、複数のフィン部材60同士をカシメ部によって部分的に固定して互いに接続した部分接続構造を採用することで、放熱部を簡便に構成することができる。
ところが、図5に比較例として示すように、放熱フィン35’,36’の全体を、フィン部材60を用いて部分接続構造として構成すると、ヒートパイプ73が接触していない領域Bでは、ヒートパイプ73から各フィン部材60へと直接的に熱伝導によって熱を導くことができないので、領域Bでは有効な放熱ができないおそれがある。
このように、放熱フィン35,36は、部分接続構造と連続構造を組み合わせることで、簡便な構造でかつ放熱性に優れた放熱部を実現することができる。
図6に示されているように、一連の壁部に複数の流路が並列に形成された連続フィン64を押出成形によって形成する。このような連続フィン64も、壁部が連続的に繋がっているのでフィン自身の熱伝導率を高めることができるので、ヒートパイプ73に接触していない領域Bの放熱性能を向上させることができる。
