Abstract
Description
本発明の第1の態様に係る放熱器によると、発熱体に接触する放熱体の流路内に配置した複数の冷却フィンを、複数個所でジグザグに屈曲させた波板形状に形成した。このため、平板状の冷却フィンと比較して、冷却フィンの表面積を大きくすることができ、冷却フィンを薄肉化したり冷却フィンの枚数を増やしたりすることなく、当該放熱器の限られた空間における冷却性能を高めることができる。
図1に示すように、放熱ユニット1(放熱器)は、複数(本実施形態では20枚)の略矩形板状の水冷コールドプレート2を有する。複数の水冷コールドプレート2は、略同じ構造の板状体であり、図示のように縁を揃えて、互いに平行な姿勢でその厚み方向に離間して近接配置される。複数の水冷コールドプレート2は、この姿勢で、図示しない電子機器の図示しないスロット内にそれぞれ収容配置される。電子機器の一例として、アクティブフェーズドアレイアンテナなどがある。以下の説明では、本実施形態の放熱ユニット1を高出力アクティブフェーズドアレイアンテナ(以下、単に、高出力アンテナと称する)に組み込んで使用するものとする。
冷却チャンバ5内には、波板形状の複数の冷却フィン6が設けられている。冷却フィン6は、細長い矩形の板状体をその長手方向に沿った複数個所でジグザグに屈曲させたような形状を有する。ここでは、このような形状を波板形状と称する。このように、冷却フィン6を波板形状にすることにより、同じ長さの平らな板と比較して、冷却フィン6の表面積を大きくすることができる。複数の冷却フィン6は、略同じ形状を有し、それぞれ、冷却チャンバ5内で冷媒の流通方向と交差する方向に延設されている。本実施形態では、全ての冷却フィン6が、冷却コールドプレート2(図3では一部のみを図示)の厚み方向に延設されている。
