- ファンの冷却風によって発熱体を冷却する電子機器において、
前記電子機器は、前記発熱体を載置する回路基板と、該回路基板に対向配置されたファンとを有し、
前記回路基板は、該ファンの回転平面と略平行に対向配置される第1の基板面と、前記第1の基板面に延設され回動自在な折れ曲がり部を介して前記第1の基板面に対し所定の角度で傾斜された第2の基板面を有しており、
前記発熱体は、前記回路基板の前記第2の基板面に載置されてなり、
前記ファンからの冷却風が前記第2の基板面の前記ファンに近い位置から遠い位置に向けて導風され、該導風された冷却風によって前記第2の基板面に載置された前記発熱体を冷却することを特徴とした電子機器。 - 請求項1に記載の電子機器において、
前記回路基板の第2の基板面の傾斜角度は、前記発熱体の発熱温度、および前記ファンの通風量に応じて異なる角度で設定されることを特徴とする電子機器。 - 請求項1または2に記載の電子機器において、
前記回路基板の第1の基板面は、前記ファンの中心部において構成され、前記第2の基板面は前記ファンの周辺部を含んで複数個構成され、前記第2の基板面に載置する前記発熱体の複数個を前記ファンによって冷却可能としたことを特徴とする電子機器。
