本開示中に段階的に記載されている数値範囲において、一つの数値範囲で記載された上限値又は下限値は、他の段階的な記載の数値範囲の上限値又は下限値に置き換えてもよい。また、本開示中に記載されている数値範囲において、その数値範囲の上限値又は下限値は、実施例に示されている値に置き換えてもよい。
本開示において「層」との語には、当該層が存在する領域を観察したときに、当該領域の全体に形成されている場合に加え、当該領域の一部にのみ形成されている場合も含まれる。
本開示において「積層」との語は、層を積み重ねることを示し、二以上の層が結合されていてもよく、二以上の層が着脱可能であってもよい。
本開示において、部材の厚みに言及する場合、当該厚みは、別段の指定がない限り、任意の10箇所で測定された厚みの算術平均値を表す。
本開示において実施形態を図面を参照して説明する場合、当該実施形態の構成は図面に示された構成に限定されない。また、各図における部材の大きさは概念的なものであり、部材間の大きさの相対的な関係はこれに限定されない。また、各図面において、実質的に同じ機能を有する部材には、全図面同じ符号を付与し、重複する説明は省略する場合がある。
本開示の熱交換器は、熱媒体流入口及び熱媒体流出口が設けられた中空の外包材を備え、前記外包材によって形成される、第1の主面と、前記第1の主面に対向する第2の主面と、前記第1の主面及び前記第2の主面の連結部と、を有し、前記外包材への熱媒体の流入によって、前記第1の主面と前記第2の主面との間の厚みが変動可能に構成されている。本開示の熱交換器は、上記構成を有することにより、被熱交換体の熱交換効率を向上させることが可能である。
図1には熱交換器100の概略斜視図が示され、図2には図1のA-A線断面図が示されている。熱交換器100は、熱媒体流入口及び熱媒体流出口が設けられた中空の外包材1を備える。熱交換器100は、第1の主面1aと、前記第1の主面1aに対向する第2の主面1bと、前記第1の主面1a及び第2の主面1bの周縁部に設けられ第1の主面1a及び第2の主面1bを連結する連結部1cと、を有することによって、中空に形成されている。熱媒体流入口及び熱媒体流出口には、図示されるようにジョイントパイプ3a及び3bがそれぞれ設けられており、ジョイントパイプ3a及び3bを介して熱媒体が外包材1の内部に流入及び内部から流出するように構成されている。熱媒体流入口から熱媒体が流入すると、熱交換器100の内圧が上昇することによって、熱媒体が流入していないときと比べて、熱交換器100の厚みを大きくする応力が働く。これにより、熱交換器100上に被熱交換体を設けたときに、被熱交換体との密着が向上し、熱交換効率を向上させることができる。
また、「連結部」は第1の主面及び第2の主面が連結される部位を意味するが、必ずしも第1の主面を構成する材料及び第2の主面を構成する材料と別個の材料で構成されている必要はなく、第1の主面を構成する材料及び第2の主面を構成する材料自体により形成される部位であり得る。
なお、本開示において「シート状」という場合、その厚さ及び材質は制限されない。
熱交換器のとりうる厚み、例えば最大厚みは、所望の用途に応じて適宜調整可能である。例えば、熱交換器の最大厚みは0.5mm~50mmであってもよく、1.0mm~45mmでもよく、5.0~40mmでもよい。
以下、本開示の熱交換器の各部材及び作用について説明する。
外包材は中空に形成されており、熱媒体流入口及び熱媒体流出口が設けられている。
樹脂層が金属層の内側及び外側の両方に設けられる場合、上記樹脂層の厚みは、それぞれの樹脂層の厚みを表す。
一態様において、樹脂層が金属層の内側及び外側の両方に設けられる場合、金属層の十分な保護の観点からは、内側の樹脂層の厚みは外側の樹脂層の厚み以上であってもよい。
一態様において、熱交換器は、外包材の内部に配置される内心材をさらに備えてもよい。内心材は、熱交換器の形状維持、熱交換効率の向上等のために用い得る。
一態様において、内心材は、金属層を樹脂で被覆したものであってもよい。内心材が、金属層を樹脂で被覆したものである場合、金属層と樹脂との間に他の層が設けられていてもよく、設けられていなくてもよい。
本開示において、内心材の凹部の深さとは、内心材の厚み方向の中間位置から最深部までの深さであり、凸部の高さとは、内心材の厚み方向の中間位置から最頂部までの高さであり、凹部の深さと凸部の高さとを加算した寸法が、内心材の厚みに相当する。
一態様において、内心材の厚みが部位によって異なる場合には、内心材の凹部の深さ又は凸部の高さの最大値が上記範囲であってもよい。
熱交換器は、外包材及び内心材以外の構造を有していてもよい。
一態様において、熱交換器は、熱媒体流入口及び熱媒体流出口に、ジョイントパイプがそれぞれ設けられ、ジョイントパイプを介して熱媒体が前記外包材の内部に流入又は流出するように構成されていてもよい。ジョイントパイプの材質は特に制限されない。一態様において、ジョイントパイプは樹脂層を有し、樹脂層を有する外包材と融着していてもよい。ジョイントパイプと外包材とを融着させることによって、液漏れを防止しやすい。
本開示の熱交換器の用途は特に制限されない。熱交換器は、熱交換が望まれる種々の用途において冷却器又は加熱器として適用可能である。したがって、熱媒体は冷媒であってもよく、熱媒であってもよい。
本開示の構造体は、前述の本開示の熱交換器と、前記熱交換器上に設けられる被熱交換体と、を有する。
本開示の構造体の製造方法は、前述の本開示の熱交換器上に被熱交換体を配置することを含む。熱交換器、被熱交換体及び構造体の詳細は前述の通りである。
