Description
前記電子部品に冷却用の流体を導く為に前記電子部品に出口側が対向するように設けら
れ、小口径部と大口径部とが繋がった断面略凸形状の管で構成される第1のダクトと、
前記第1のダクトにおける大口径部の管の中に設けられ、該大口径部より口径が小さな第2のダクトと、
前記第1のダクトの小口径部の入口側に対応して設けられた第1のファンと、
前記第2のダクトの出口側に対応して設けられた第2のファンと、
前記第1のダクトの小口径部の出口側であって、前記第2のダクトの入口側に対応して設けられた第3のファンと、
前記第1のファンによって第1のダクトの小口径部の入口側から供給されて来た冷却用の流体の一部が、第2のダクトの外側であって、かつ、第1のダクトの大口径部の内側を介して排出可能に構成され、冷却用の流体の一部を前記電子部品に導くバイパス流路
とを具備することを特徴とする冷却機構によって解決される。
図1〜図3は本発明になる冷却機構の実施形態を説明するもので、図1は冷却機構の概略説明図、図2(1),(2),(3)は本発明の冷却機構の特徴を本発明外の冷却機構と対比して説明するものであり、図3は本発明の冷却機構の特長を説明するグラフである。
