Description
実施の形態1.
図1は、この発明の実施の形態1による熱交換器を示す斜視図である。図において、熱交換器1は、冷媒分配器としての第1のヘッダタンク2と、第1のヘッダタンク2から離して配置されている第2のヘッダタンク3と、第1及び第2のヘッダタンク2,3を互いに連結する複数の伝熱管4と、複数の伝熱管4の間に設けられているフィン5とを有している。熱交換器1は、冷媒が循環する冷凍サイクル装置における蒸発器として機能する。
図5は、この発明の実施の形態2による熱交換器1の要部を示す断面図である。図5は、実施の形態1の図3に対応する図である。本実施の形態では、第1のヘッダタンク2の長手方向、即ち第1方向zに沿って第1のヘッダタンク2を見たとき、第2の空間形成部12の上面及び第2の空間形成部12内の底面14が、水平面に対して傾斜している。また、第2の空間形成部12の上面及び第2の空間形成部12内の底面14は、第1方向zに沿って第1のヘッダタンク2を見たとき、第1の空間形成部11の下部から斜め下方へ傾斜している。この例では、第2の空間形成部12の上面及び第2の空間形成部12内の底面14が、第1の空間形成部11の下部から風上側に向かって斜め下方へ傾斜している。
図7は、この実施の形態3による熱交換器1の第1のヘッダタンク2を示す斜視図である。また、図8は、図7の第1のヘッダタンク2の長手方向に直交する平面で熱交換器1を切断したときの第1のヘッダタンク2を示す断面図である。本実施の形態では、第1の冷媒口19及び第2の冷媒口20のそれぞれの位置が実施の形態1及び2と異なっている。
図9は、この発明の実施の形態4による冷凍サイクル装置を示す構成図である。冷凍サイクル装置31は、圧縮機32、凝縮熱交換器33、膨張弁34、蒸発熱交換器35を含む冷凍サイクル回路を備えている。冷凍サイクル装置31では、圧縮機32が駆動することにより、圧縮機32、凝縮熱交換器33、膨張弁34及び蒸発熱交換器35を冷媒が相変化しながら循環する冷凍サイクルが行われる。本実施の形態では、冷凍サイクル回路を循環する冷媒が図9の矢印の方向へ流れる。
図10は、この発明の実施の形態5による冷凍サイクル装置を示す構成図である。冷凍サイクル装置41は、圧縮機42、室外熱交換器43、膨張弁44、室内熱交換器45及び四方弁46を含む冷凍サイクル回路を有している。冷凍サイクル装置41では、圧縮機42が駆動することにより、圧縮機42、室外熱交換器43、膨張弁44及び室内熱交換器45を冷媒が相変化しながら循環する冷凍サイクルが行われる。本実施の形態では、圧縮機42、室外熱交換器43、膨張弁44及び四方弁46が室外機に設けられ、室内熱交換器45が室内機に設けられている。
