Abstract
Description
図1〜図10を参照して、本実施形態による沸騰式冷却器100(以下、冷却器100という)の構成について説明する。冷却器100は、冷媒の気化と凝縮との相変化のサイクルを利用して、発熱源HSからの熱を吸収して、外部に放熱する沸騰冷却方式による冷却器である。発熱源HSは、特に限定されないが、たとえばサーバ等の電子機器に搭載されるCPUなどの半導体チップや電子回路などである。本実施形態による冷却器100は、サーバラックに設置されるサーバ等のCPUの冷却など、設置高さが限定されたスペースに設置される用途に特に好適に適用される。
図1および図2に示すように、冷却器100は、沸騰部10と、凝縮部20と、接続管30と、を備えている。沸騰部10と凝縮部20とが接続管30により接続されることにより、単一の冷却器本体100aが構成されている。冷却器本体100aは、たとえばアルミニウム(アルミニウム合金を含む)、銅(銅合金を含む)などの熱伝導性の高い金属材料により形成されている。また、冷却器100は、沸騰部10と、接続管30と、凝縮部20の後述する冷媒通路21とによって、密閉された内部空間を有している。この密閉空間内に、冷媒1が収容されている。
次に、図3を参照して、本実施形態の冷却器100の各部の寸法関係について説明する。
冷媒通路21内の伝熱フィン25、第1外部通路23の伝熱フィン23b、および第2外部通路24の伝熱フィン24bは、たとえば、コルゲートフィンである。例えば図4では曲線状の波状断面のコルゲートフィンを示しているが、矩形断面のコルゲートフィンであってもよい。伝熱フィン25、伝熱フィン23bおよび伝熱フィン24bには、同一形状のフィンを用いてもよいし、それぞれ異なる形状のフィンを用いてもよい。フィンの形状としては、プレーンフィン、パーホレートフィン、ルーバーフィン、ヘリンボーンフィン、セレートフィン(オフセットフィン)などのいずれでもよい。
冷却器100の動作を説明する。図3に示したように、発熱源HSが発熱すると、沸騰部10内の冷媒1が沸騰することによって気化して冷媒ガス1aになる。冷媒ガス1aは、沸騰部10の内部空間11に充満し、沸騰が継続することによって沸騰部10から接続管30へ流入する。冷媒ガス1aは、接続管30を通って凝縮部20へ流入する。凝縮部20では、冷媒ガス1aが、直接、または接続通路部60を通ってそれぞれの冷媒通路21のY方向中央部に流入する。流入した冷媒ガス1aは、冷媒通路21の内部をY方向中央から外側に向けて、伝熱フィン25に沿って流通する。
本実施形態では、以下のような効果を得ることができる。
なお、今回開示された実施形態は、すべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は、上記した実施形態の説明ではなく請求の範囲によって示され、さらに請求の範囲と均等の意味および範囲内でのすべての変更(変形例)が含まれる。
