Abstract
Description
ここで、上昇気流発生面の上方部分は、順次に上昇してくる空気がフロアトンネル部に当たるため、電装部品容器の上方部分よりも、気圧が高くなっている。即ち、受電側コイルユニットの上方には、上昇気流発生面の上方に対応する高圧部と、電装部品容器の上方に対応する低圧部と、によって気圧勾配が形成される。
ここで、上昇気流発生面47の上方部分は、順次に上昇してくる空気67がフロアトンネル部7に当たるため、ジャンクションボックス13の上方部分よりも、気圧が高くなる。即ち、受電側コイルユニット23の上方には、上昇気流発生面47の上方に対応する高圧部と、ジャンクションボックス13の上方に対応する低圧部と、によって気圧勾配が形成される。
このように、閉断面部61内に配置された受電側コイルユニット23を自然対流を用いて放熱することにより、閉断面部61内に熱が篭もることなく、小型化した受電側コイルユニット23で受電側コイル49の温度上昇を抑制できる。
