Description
発明者らが本開示に想到するに至った当時、プレートフィン積層型熱交換器のプレートフィンは、特許文献1に示すように、ヘッダ流路用開口と伝熱流路用凹溝を備えた二枚のプレートを向かい合わせにロウ付け接合して構成してあり、接合箇所の多さと流路構成の複雑さから接合不良が発生しやすい。そのため、接合不良を低減して信頼性を向上させる必要がある、という課題があった。また、二枚のプレートを接合して構成しているので、その分厚肉構成となってプレートフィン間を流れる流体の通流抵抗が増加し熱交換性能が低下するとともに、熱交換器全体の重量も重いものとなる、という課題もあった。
以下、図1~図8を用いて、実施の形態1を説明する。
図1に示すように、本実施形態の熱交換器1は、短冊状のプレートフィン2aを積層したプレートフィン積層体2の両側に平面視が略同一形状のエンドプレート3a、3bを接合一体化して構成してある。そして、その一端部側に、凝縮器として用いる場合には入口となり蒸発器として用いる場合は出口となる管A4及びその逆となる管B5とを有している。
次に上記のように構成したプレートフィン積層型熱交換器について、これを空気調和機の熱交換器として用いた場合を例にしてその作用効果を説明する。
以上のように、本開示のプレートフィン積層型熱交換器は、ヘッダ流路A9,B10間に伝熱流路8を有するプレートフィン2aを複数積層して構成した熱交換器であって、前記プレートフィン2aはヘッダ流路を有するヘッダ領域部11と伝熱流路8を有する流路領域部12とからなり、前記ヘッダ領域部11はヘッダ流路用開口を有する二枚のプレート16a,16bを接合して構成するとともに、前記流路領域部12は伝熱流路8を一体成型した一枚の流路用プレート18で構成し、前記ヘッダ領域部11と流路領域部12とを一体に接合してプレートフィン2aとした構成としている。
以下、図10、図11を用いて、実施の形態2を説明する。
図10は実施の形態1におけるプレートフィン積層型熱交換器を用いて構成した空気調和機の冷凍サイクル図、図11は同空気調和機の室内機を示す概略断面図である。
上記構成からなる空気調和機は、冷房運転時には、四方弁54を圧縮機53の吐出側と室外熱交換器55とが連通するように切り換える。これにより、圧縮機53によって圧縮された冷媒は高温高圧の気相冷媒となって四方弁54を通って室外熱交換器55に送られる。そして、外気と熱交換して放熱し、高圧の液相冷媒となり、減圧器56に送られる。減圧器56では減圧されて低温低圧の二相冷媒となり、室内機52に送られる。室内機52では、冷媒は室内熱交換器57に入り室内空気と熱交換して吸熱し、蒸発気化して低温のガス冷媒となる。この時室内空気は冷却されて室内を冷房する。さらに冷媒は室外機51に戻り、四方弁54を経由して圧縮機53に戻される。
本開示の冷凍システムは、室内熱交換器57に前記実施の形態1で示した熱交換器を使用しているので、軽量で高性能かつ高い信頼性を持つ冷凍システムとすることができる。
以上、本発明に係るプレートフィン積層型熱交換器及びそれを用いた冷凍システムについて、上記実施の形態を用いて説明したが、本発明はこれに限定されるものではなく、種々の変更、置き換え、付加、省略などを行うことができる。例えば、第1流体は冷媒、第2流体は空気とした場合を例示したが、これに限定されるものではない。また、冷凍システムとして空気調和機を例示したが、冷蔵庫や冷凍ケース等であってもよいし、第2流体を水としたヒートポンプ給湯器であってもよいものである。つまり、今回開示した実施の形態はすべての点で例示であって制限的なものではなく、本発明の範囲は特許請求の範囲によって示され、特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれるものである。
