Description
本発明では、遠心方向に2つの流出口が設けられており、さらにその2つの流出口にそれぞれ放熱板が設けられているので、さらに冷却効率を高めることができる。
本発明において、放熱部より吸熱部に近い側の部位とは、放熱部と吸熱部との間のうちいずれかの部位をいう。本発明では、熱輸送体の部位によって異なる放熱量に応じて表面積の異なる放熱板を設けている。これにより、冷却効率を最適なものにすることができる。特に、本発明では、吸熱部側に接する第2の放熱板の表面積が、放熱部側に接する第1の放熱板の表面積より小さくなるように構成しており、これにより第2の放熱板の大きさを極力小さくしつつ冷却効率を高めることができる。
