Claims (4)
- 基板上に配設される複数の放熱板と、該複数の放熱板の一部に送風する冷却ファンとを含み、前記基板及び該基板上に配設される電子部品を冷却する回路基板の冷却機構であって、
前記基板の一端には、前記基板を接地することにより前記電子部品からの電磁波ノイズの漏出を防止する金属板が付設され、前記金属板を前記基板に沿ってL字状に折り曲げて折曲部が形成されており、前記冷却ファンを前記折曲部の内側に前記基板に対し垂直に配置するとともに、前記冷却ファンからの送風を受ける放熱板の受風面を前記冷却ファンの軸流方向に対し斜めに配置し、前記金属板と前記冷却ファンからの送風を受ける放熱板との間、及び前記金属板と前記冷却ファンからの送風を受けない放熱板との間に連結部を設けることにより、前記冷却ファンからの送風を受ける放熱板と前記冷却ファンからの送風を受けない放熱板とを前記金属板及び前記連結部を介して連結することを特徴とする回路基板の冷却機構。 - 前記基板の前記冷却ファンが配置される部分には切り欠き部が形成されることを特徴とする請求項1に記載の回路基板の冷却機構。
- 前記折曲部の少なくとも一部が前記基板の表面側若しくは裏面側に突設されており、前記冷却ファンは、送風面が前記基板により分割されるように配置されることを特徴とする請求項1又は請求項2に記載の回路基板の冷却機構。
- 前記冷却ファンの軸流方向に対する前記受風面の角度は、前記冷却ファンからの送風が送風方向下流側に配置された他の放熱板及び電子部品の少なくとも一方に誘導されるように設定されることを特徴とする請求項1乃至請求項3のいずれかに記載の回路基板の冷却機構。
