また、対向する面のうち一方の面に接する側の折曲部に設けられる連通路の短手方向の範囲は、他方の面に接する折曲部に設けられる連通路の短手方向の範囲と重複することを特徴とする。
(実施の形態1)
図1に示すように、熱交換器100は、冷媒が流通する複数のチューブ110が並設され、隣接するチューブ110間にフィン120がロウ付けによって接合されて構成されている。図示例において、複数のチューブ110の長手方向(冷媒の流通方向)の両端にはそれぞれ中空のヘッダタンク130,135が連通されており、上部側に設けられたヘッダタンク130は、一端側に冷媒の入口部130aが、他端側に冷媒の出口部130bが設けられ、中央には内部を隔絶する仕切板131が設けられている。これにより、ヘッダタンク130の入口部130aから流入した冷媒は、仕切板131よりも入口部130a側に連通されたチューブ110(図1において左側の2本)を流通して下部側に設けられたヘッダタンク135に流入する。そして、該ヘッダタンク135から仕切板よりも出口部130b側に連通されたチューブ110(図1において右側の2本)を流通して、ヘッダタンク130を介して出口部130bから流出する。なお、図1は熱交換器100を模式的に表したものであり、説明の簡単のために簡略化されているものである。
図5及び図6に、実施の形態2による熱交換器200におけるフィン220を示す。なお、実施の形態2による熱交換器200は、実施の形態1による熱交換器100におけるフィン120に対して、実施の形態1とは異なる構造のフィン220が設けられた構成を有するため、ここではフィン220以外の説明を省略する。
図7及び図8に、実施の形態3による熱交換器300におけるフィン320を示す。なお、実施の形態3による熱交換器300は、実施の形態1による熱交換器100におけるフィン120に対して実施の形態1とは異なる構造のフィン320が設けられた構成を有するため、ここではフィン320以外の説明を省略する。
上記実施の形態1乃至3に例示した熱交換器(100,200,300)が使用される一例として、例えば電気自動車等に設けられる空気調和装置1の全体の構成図を図9に示す。この空気調和装置1はいわゆるヒートポンプサイクルを利用したものであり、車外用の熱交換器100A及び車内用の熱交換器100Bに対する圧縮機11からの冷媒の流れを四方弁13によって切り替えることで冷房と暖房の切換を行うものである。なお、熱交換器100A及び熱交換器100Bは、熱交換器100、200及び300のいずれかに対応するものであり、ここでは、実施の形態1における熱交換器100に対応するものとして説明する。
