【発明の属する技術分野】
本発明は、板状のブロック体からなるヘッダ本体の外周部に、熱源からの熱媒受入用接続部、熱源への熱媒戻し用接続部、床暖房パネルの複数の熱媒入口に接続される複数の熱媒供給部、及び、床暖房パネルの複数の熱媒出口に接続される複数の熱媒排出部の夫々が備えられ、前記ヘッダ本体の内部に、前記熱媒受入用接続部と前記複数の熱媒供給部夫々とを連通接続する熱媒供給用連通路、及び、前記熱媒戻し用接続部と前記複数の熱媒排出部夫々とを連通接続する熱媒戻し用連通路が夫々形成されて構成されている床暖房パネル用熱媒ヘッダに関する。
【0002】
【従来の技術】
上記構成の床暖房パネル用熱媒ヘッダは、熱源から外部供給管を通して供給される熱媒を床暖房パネルに備えられている複数の熱媒流通管に分流させて供給するとともに、その複数の熱媒流通管を通過して戻ってくる熱媒を合流させて外部戻り管を通して熱源に戻すように、外部供給管及び外部戻り管を複数の熱媒流通管に接続させるために設けられるものであるが、このような床暖房パネル用熱媒ヘッダとして、従来では、次のように構成されたものがあった。
【0003】
つまり、熱媒を複数の熱媒流通管に分流させるための熱媒供給用連通路、及び、複数の熱媒流通管から熱媒を合流させるための熱媒戻し用連通路の夫々が、共に、ヘッダ本体の板厚方向とほぼ直交する方向に沿って延びる1本の通路として形成されていた(例えば、特許文献1参照。)。
【0004】
【特許文献1】
特開平9−269135号公報参照
【0005】
【発明が解決しようとする課題】
近年では、例えば、建物のバリアフリー化の要求等によって、床暖房パネルが設置される床と敷居との段差を小さくすることが要求されている。このため、床に設置したときに床暖房パネルが敷居よりも上方に突出してしまうのを抑制すべく、床暖房パネルを薄くする薄型化の要望が強くなっている。
【0006】
床暖房パネルは、その内部に備えられる熱媒流通管を小径にすることでパネルの厚みを薄くすることが可能であり、そのとき、熱媒流通管の本数を変えずに単に小径にしただけでは熱媒通流量、つまり、熱媒流通管に通流する熱媒供給量が低下するため、小径の熱媒流通管の本数を多くして並列状態で床暖房パネル用熱媒ヘッダに接続することにより熱媒供給量を確保することができる。つまり、床暖房パネルは、熱媒流通管を小径とし、且つ、その本数を多くすることで、熱媒供給量を確保しながら薄くすることが可能である。
【0007】
そして、床暖房パネルを薄型化するためには、板状のブロック体からなるヘッダ本体の厚みを薄くして、床暖房パネル用熱媒ヘッダをも薄型化することが必要である。ヘッダ本体の厚みを薄くするためには、ヘッダ本体の内部に設けられる熱媒供給用連通路や熱媒戻し用連通路を小径にすることになるが、1本の通路として形成されている熱媒供給用連通路や熱媒戻し用連通路の通路抵抗が大になり、この通路抵抗の増大のために、床暖房パネルに対して熱源から循環供給可能な熱媒供給量が少なくなり、暖房能力が低下するおそれがあった。
【0008】
本発明はかかる点に着目してなされたものであり、その目的は、暖房能力を低下させることなく床暖房パネルを薄型化することが可能となる床暖房パネル用熱媒ヘッダを提供する点にある。
【0009】
【課題を解決するための手段】
請求項1に記載の床暖房パネル用熱媒ヘッダは、板状のブロック体からなるヘッダ本体の外周部に、熱源からの熱媒受入用接続部、熱源への熱媒戻し用接続部、床暖房パネルの複数の熱媒入口に接続される複数の熱媒供給部、及び、床暖房パネルの複数の熱媒出口に接続される複数の熱媒排出部の夫々が備えられ、
前記ヘッダ本体の内部に、前記熱媒受入用接続部と前記複数の熱媒供給部夫々とを連通接続する熱媒供給用連通路、及び、前記熱媒戻し用接続部と前記複数の熱媒排出部夫々とを連通接続する熱媒戻し用連通路が夫々形成されて構成されているものであって、
前記熱媒供給用連通路が、前記熱媒受入用接続部と前記複数の熱媒供給部夫々との間を連通接続する複数の連通路構成用の熱媒供給路を、前記ヘッダ本体の板厚方向と直交又はほぼ直交する方向に沿うように平行状に並べて備える状態で構成され、
前記熱媒戻し用連通路が、前記熱媒戻し用接続部と前記複数の熱媒排出部夫々との間を連通接続する複数の連通路構成用の熱媒戻し路を、前記ヘッダ本体の厚み方向と直交又はほぼ直交する方向に沿うように平行状に並べて備える状態で構成され
前記熱媒受入用接続部が、前記熱媒供給用連通路の経路長手方向の中央位置に位置させる状態で備えられ、
前記複数の熱媒供給部が、前記熱媒供給用連通路の経路長手方向の中央位置に対して左右両側に振り分けて分散配置される状態で設けられ、
前記熱媒戻し用接続部が、前記熱媒戻し用連通路の経路長手方向の中央位置に位置させる状態で設けられ、
前記複数の熱媒排出部が、前記熱媒戻し用連通路の経路長手方向の中央位置に対して左右両側に振り分けて分散配置される状態で設けられていることを特徴とする。
【0010】
すなわち、ヘッダ本体の内部に形成される熱媒供給用連通路が、複数の連通路構成用の熱媒供給路を、ヘッダ本体の板厚方向と直交又はほぼ直交する方向に沿うように並べて備える状態で構成されるので、複数の連通路構成用の熱媒供給路の夫々を通路面積が小さい小径のものにした場合であっても、熱媒供給用連通路全体としては大きな通路面積を確保して通路抵抗が増加しないようにすることができるものとなり、床暖房パネルに対して熱源から循環供給可能な熱媒供給量として充分な量を確保することが可能となる。しかも、前記各連通路構成用の熱媒供給路が小径であるから、ヘッダ本体の板厚を薄くすることが可能となる。
【0011】
又、ヘッダ本体の内部に形成される熱媒戻し用連通路についても、熱媒供給用連通路と同様にして、複数の連通路構成用の熱媒戻し路を、ヘッダ本体の板厚方向と直交又はほぼ直交する方向に沿うように並べて備える状態で構成されるので、複数の連通路構成用の熱媒戻し路の夫々を通路面積が小さい小径のものにした場合であっても、熱媒戻し用連通路全体としては大きな通路面積を確保して通路抵抗が増加しないようにすることができるものとなり、床暖房パネルに対して熱源から循環供給可能な熱媒供給量として充分な量を確保することが可能となる。しかも、前記各連通路構成用の熱媒戻し路が小径であるから、ヘッダ本体の厚みを薄くすることが可能となる。
【0012】
従って、床暖房パネルの暖房能力を低下させることなく、ヘッダ本体の厚みを薄くすることによって床暖房パネルを薄型化することが可能となる床暖房パネル用熱媒ヘッダを提供できるに至った。
【0014】
又、請求項1の発明によれば、熱媒供給用連通路の経路長手方向の左右両側に振り分けて分散配置される複数の熱媒供給部に対して、熱媒供給用連通路の経路長手方向の中央位置にある熱媒受入用接続部から左右両側に分流させるので、熱媒受入用接続部から複数の熱媒供給部への経路長さを短いものにできる。
【0015】
又、熱媒の戻り経路においても同様にして、熱媒戻し用連通路の経路長手方向の左右両側に振り分けて分散配置される複数の熱媒供給部から、熱媒戻し用連通路の経路長手方向の中央位置に位置する熱媒戻し用接続部に向けて通流しながら合流させる構成であるから、複数の熱媒排出部から熱媒戻し用接続部への経路長さを短いものにできる。
【0016】
従って、熱媒供給用連通路並びに熱媒戻り用連通路の夫々において、熱媒が通過する経路長さを短くして通路抵抗を小さいものにすることが可能となる。
【0017】
請求項記載の床暖房パネル用熱媒ヘッダは、請求項1において、前記複数の熱媒供給部及び複数の熱媒排出部の夫々が、前記ヘッダ本体の板厚方向と直交又はほぼ直交する方向に沿って前記ヘッダ本体から突出する状態で備えられ、前記熱媒受入用接続部及び前記熱媒戻し用接続部の夫々が、前記ヘッダ本体の板厚方向に沿って前記ヘッダ本体から突出する状態で備えられていることを特徴とする。
【0018】
すなわち、床暖房パネルに備えられる熱媒流通管はパネルの板厚と直交又はほぼ直交する方向に沿って設けられるものであり、これらの熱媒流通管に対して、ヘッダ本体の板厚方向と直交又はほぼ直交する方向に沿ってヘッダ本体から突出する状態で備えられる複数の熱媒供給部及び複数の熱媒排出部が接続されることになる。そして、前記熱媒受入用接続部及び前記熱媒戻し用接続部の夫々が、ヘッダ本体の板厚方向に沿ってヘッダ本体から突出する状態で備えられているから、外部配管との接続のための配管構成を簡単な構成で済ませることが可能となる。
【0019】
説明を加えると、前記熱媒受入用接続部及び前記熱媒戻し用接続部の夫々が、ヘッダ本体の板厚方向に沿ってヘッダ本体から突出する状態で備えられているから、例えば外部供給管や外部戻し管等の熱源に対する外部配管を配管接続させる場合に、ヘッダ本体の下方側に位置する床に挿通孔を形成して、その挿通孔に対して熱媒受入用接続部及び熱媒戻し用接続部を挿通させて上述したような外部配管をそのまま接続させることができ、外部配管との接続のための配管構成を簡単な構成で済ませることが可能となるのである。
【0020】
【発明の実施の形態】
以下、本発明に係る床暖房パネル用熱媒ヘッダについて図面に基づいて説明する。
図1に、暖房パネル用熱媒ヘッダ4を備えた床暖房パネルを示している。この床暖房パネルは、矩形板状の複数(図1に示す例では6個)の板状基材1が備えられ、それら複数の板状基材1にわたって収納される状態で複数(図1に示す例では6本)の熱媒流通管2を備えて構成されている。複数の板状基材1のうちの1つの板状基材1の外端縁にその一部を矩形状に切り欠いた状態でヘッダ配設空間3が形成され、そのヘッダ配設空間3に前記暖房パネル用熱媒ヘッダ4(以下、単に熱媒ヘッダ4という)が備えられている。
【0021】
前記複数の板状基材1の夫々には、図2に示すように、熱媒流通管2を収納状態に配設するための凹入状の溝部5が形成され、この溝部5に熱媒流通管2を収納させて板状基材1の表面部に均熱材としてのアルミ箔6を貼り付ける構成となっている。
【0022】
そして、複数の板状基材1にわたって連なるように熱媒流通管2を蛇行状に配設するように構成されている。つまり、図3に示すように、6本の熱媒流通管2の夫々の熱媒入口7と熱媒出口8とが前記ヘッダ配設空間3に位置するように配置され、それら6本の熱媒流通管2のうちの3本のものが、ヘッダ配設空間3が形成される板状基材1、その板状基材1と短辺同士を突き合わせる状態で隣接する板状基材1、及び、その板状基材1に長辺同士を突き合わせる状態で隣接する板状基材1、更に、その板状基材1に長辺同士を突き合わせる状態で隣接する板状基材1の夫々にわたって連なる状態で蛇行状に配設される構成となっている。
【0023】
又、残りの3本の熱媒流通管2は、ヘッダ配設空間3が形成される板状基材1、その板状基材1と長辺同士を突き合わせる状態で隣接する板状基材1、更に、その板状基材1に長辺同士を突き合わせる状態で隣接する板状基材1の夫々にわたって連なる状態で蛇行状に配設される構成となっている。
【0024】
この床暖房パネルは、製造工場から施工場所まで運搬するような場合には、複数の板状基材1を互いに折り畳んで収納できるようになっている。つまり、図5に示すように、複数の板状基材1を折り畳むときには、板状基材1同士が接続される部分において板状基材1同士を離間させ、熱媒流通管2を介して板状基材1同士が繋がっている状態で板状基材1を互いに重ね合わせる状態で折り畳むことが可能なように構成されている。尚、設置前においては板状基材1同士が接続される箇所にはアルミ箔6は貼り付けられていない。そして、施工場所においては、折り畳んだ床暖房パネルを広げて暖房対象の床面に敷設し、隣接する各板状基材1同士を突き合わせた状態で、板状基材1同士が接続される箇所に沿って上面側を覆うように後付けのアルミ箔6を貼り付けて、図1に示すように、各板状基材1が密接するように接続された状態で床に設置させる構成となっている。
【0025】
前記複数の熱媒流通管2は、板状基材1同士が分離して折れ曲がる箇所においては、図1に示すように、その板状基材1同士を折り畳むときに無理な力がかかり損傷することがないように管路軸芯方向が折れ線方向にほぼ沿うような姿勢となるように湾曲させる構成となっている。
【0026】
そして、この床暖房パネルは、前記ヘッダ配設空間3に備えられた熱媒ヘッダ4を介して外部の給湯器等の熱源(図示せず)から温水等の熱媒を熱媒流通管2に供給し、熱媒流通管2を通流した熱媒を熱媒ヘッダ4を介して熱源に戻すようにして、熱媒を熱源から熱媒流通管2に循環供給することにより暖房するように構成されている。
【0027】
次に、熱媒ヘッダ4の構成について詳述する。
図6に示すように、この熱媒ヘッダ4は、板状のブロック体からなるヘッダ本体9の外周部に、熱源からの熱媒受入用接続部10、熱源への熱媒戻し用接続部11、複数の熱媒入口7に接続される複数の熱媒供給部12、及び、複数の熱媒出口8に接続される複数の熱媒排出部13の夫々が備えられ、前記各熱媒流通管2の複数の熱媒入口7に複数の熱媒供給部12が夫々接続され、複数の熱媒出口8に複数の熱媒排出部13の夫々が接続されている。又、複数の熱媒供給部12及び複数の熱媒排出部13の夫々が、ヘッダ本体9の板厚方向と直交又はほぼ直交する方向に沿ってヘッダ本体9から突出する状態で備えられ、熱媒受入用接続部10及び熱媒戻し用接続部11の夫々が、ヘッダ本体9の板厚方向に沿ってヘッダ本体9から突出する状態で備えられている。
【0028】
そして、図3に示すように、ヘッダ配設空間3における矩形状の切欠の左右両側の側縁のうちの一方の側縁14において、3本の熱媒流通管2夫々の熱媒入口7と熱媒出口8とが側縁に沿って交互に並ぶ状態で備えられ、対向する他方の側縁15には残りの3本の熱媒流通管2夫々の熱媒入口7と熱媒出口8とが側縁に沿って交互に並ぶ状態で備えられている。そして、前記各熱媒流通管2の熱媒入口7に複数の熱媒供給部12が接続され、前記各熱媒流通管2の熱媒出口8に複数の熱媒排出部13が接続されている。
【0029】
詳述すると、前記ヘッダ本体9は、図6〜図8に示すように、長方形の板状に形成されたブロック体からなり、そのヘッダ本体9の一方の長辺側の端縁16から外方側に突出する状態で3個の熱媒供給部12と3個の熱媒排出部13とがそれらが交互に並ぶ状態で配置され、他方の長辺側の端縁17にも同様に、外方側に突出する状態で3個の熱媒供給部12と3個の熱媒排出部13とが交互に配置される状態で備えられている。一方、熱媒受入用接続部10及び熱媒戻し用接続部11の夫々は、ヘッダ本体9の長辺に沿う長手方向のほぼ中間位置において短辺に沿う短手方向に沿うように並ぶ状態で、一方の板面からヘッダ本体9の板厚方向に沿って突出するように、ヘッダ本体9から突出する状態で備えられている。尚、熱媒受入用接続部10及び熱媒戻し用接続部11の夫々は、床暖房パネルが床面に設置される状態においてはヘッダ本体9から下向きに突出する状態となる。
【0030】
図9、図11に示すように、複数の熱媒供給部12は、合成樹脂材からなる熱媒流通管2の端部が外嵌する状態で接続される管路接続部12aと、この管路接続部12aの内部に形成された内部通路12bと、この内部通路12bの内奥側に位置するヘッダ本体9の内部に内部通路12bの内径よりも大径の大径孔部12cと、この大径孔部12cよりも更にヘッダ本体9の内奥側に向けて連通形成される小径孔部12dとを備えて構成されている。この小径孔部12dは前記大径孔部12cの軸芯よりもヘッダ本体9の板厚方向に沿って偏芯させた状態で連通形成されている。但し、前記小径孔部12dは、前記大径孔部12cの軸芯よりも板厚方向のうちの一方側、具体的には、前記熱媒受入用接続部10が形成される側に位置する箇所に形成されている。
【0031】
図10、図11に示すように、前記複数の熱媒排出部13も前記熱媒供給部12と同様に、合成樹脂材からなる熱媒流通管2の端部が外嵌する状態で接続される管路接続部13aと、この管路接続部13aの内部に形成された内部通路13bと、この内部通路13bの内奥側に位置するヘッダ本体9の内部に内部通路13bの内径よりも大径の大径孔部13cと、この大径孔部13cよりも更にヘッダ本体9の内奥側に向けて連通形成される小径孔部13dとを備えて構成されている。この小径孔部13dは前記大径孔部13cの軸芯よりもヘッダ本体9の板厚方向に沿って偏芯させた状態で連通形成されている。但し、この前記熱媒排出部13における前記小径孔部13dは、前記大径孔部13cの軸芯よりも板厚方向のうちの他方側、具体的には、前記熱媒受入用接続部10が形成される側とは反対側に位置する箇所に形成されている。
従って、熱媒供給部12における小径孔部12dと、熱媒排出部13における小径孔部13dとが、板厚方向に沿って互いに位置をずらした状態で形成されている。
【0032】
そして、前記ヘッダ本体9の内部には、熱媒受入用接続部10と複数の熱媒供給部12夫々とを連通接続する熱媒供給用連通路18、及び、熱媒戻し用接続部11と複数の熱媒排出部13夫々とを連通接続する熱媒戻し用連通路19が夫々形成されて構成されている。又、前記熱媒供給用連通路18が、熱媒受入用接続部10と複数の熱媒供給部12夫々との間を連通接続する複数の連通路構成用の熱媒供給路18a,18bを、ヘッダ本体9の板厚方向と直交又はほぼ直交する方向に沿うように並べて備える状態で構成され、前記熱媒戻し用連通路19が、前記熱媒戻し用接続部11と前記複数の熱媒排出部13夫々との間を連通接続する複数の連通路構成用の熱媒戻し路19a,19bを、ヘッダ本体9の厚み方向と直交又はほぼ直交する方向に沿うように並べて備える状態で構成されている。
【0033】
すなわち、図9、図11に示すように、熱媒供給用連通路18としての複数(図に示す例では2本)の連通路構成用の熱媒供給路18a,18bが、複数の熱媒供給部12における夫々の小径孔部12dを連通接続するように形成されている。つまり、2本の連通路構成用の熱媒供給路18a,18bが小径孔部12dの軸芯方向に沿って位置をずらせて、且つ、複数の熱媒供給部12における夫々の小径孔部12d同士を連通接続するように、それらの小径孔部12dの並び方向に沿って通路が形成されている。
【0034】
又、図10、図11に示すように、熱媒戻し用連通路19としての複数(図に示す例では2本)の連通路構成用の熱媒戻し路19a,19bが、複数の熱媒排出部13における夫々の小径孔部13dを連通接続するように形成されている。つまり、2本の連通路構成用の熱媒戻し路19a,19bが小径孔部13dの軸芯方向に沿って位置をずらせて、且つ、複数の熱媒排出部13における夫々の小径孔部13d同士を連通接続するように、それらの小径孔部13dの並び方向に沿って通路が形成されている。従って、前記連通路構成用の熱媒供給路18a,18bと連通路構成用の熱媒戻し路19a,19bとは、板厚方向に沿って互いに位置をずらした状態で形成されることになる。
【0035】
又、前記熱媒受入用接続部10が、前記熱媒供給用連通路18の経路長手方向の中央位置に位置させる状態で備えられ、前記複数の熱媒供給部12が、前記熱媒供給用連通路18の経路長手方向の中央位置に対して左右両側に振り分けて分散配置される状態で設けられ、前記熱媒戻し用接続部11が、前記熱媒戻し用連通路19の経路長手方向の中央位置に位置させる状態で設けられ、前記複数の熱媒排出部13が、前記熱媒戻し用連通路19の経路長手方向の中央位置に対して左右両側に振り分けて分散配置される状態で設けられている。
【0036】
すなわち、前記熱媒受入用接続部10が、2本の連通路構成用の熱媒供給路18a,18bの経路長手方向の中央位置に位置させる状態で備えられて、その熱媒受入用の内部通路10aが2本の連通路構成用の熱媒供給路18a,18bの夫々に連通接続するように構成されている。一方、前記熱媒戻し用接続部11が、2本の連通路構成用の熱媒戻し路19a,19bの経路長手方向の中央位置に位置させる状態で備えられて、その熱媒戻し用の内部通路11aが2本の連通路構成用の熱媒戻し路19a,19bの夫々に連通接続するように構成されている。
【0037】
このように熱媒ヘッダ4においては、熱媒受入用接続部10が、2本の連通路構成用の熱媒供給路18a,18bの夫々に連通接続するように構成され、且つ、熱媒戻し用接続部11が、2本の連通路構成用の熱媒戻し路19a,19bの夫々に連通接続するように構成されており、前記6本の熱媒流通管2の夫々に暖房に必要とされる流量の熱媒(温水)を循環通流させることができるが、連通路構成用の熱媒供給路18a,18b及び連通路構成用の熱媒戻し路19a,19bは、夫々、従来の連通路に比べて小径のもので構成している。具体的には経路内径が約3mmに形成されている。このようにブロック状に構成されるヘッダ本体9の内部に形成される連通路構成用の熱媒供給路18a,18b及び連通路構成用の熱媒戻し路19a,19bを夫々小径の通路で構成することで、熱媒供給量を充分確保しながらヘッダ本体9の板厚を薄くすることができた。
【0038】
前記熱媒受入用接続部10及び熱媒戻し用接続部11は、床暖房パネルを床に設置したときには、図12に示すように、ヘッダ本体9の下面よりも下方側に突出する状態となり、床暖房パネルを床に設置するときに床に形成される挿通孔20を通して、床下に向かう状態で露出して、床下を通して熱源との間で配管される外部供給管21及び外部戻り管22夫々の接続部21a,22aが差し込み装着される構成となっている。これらの外部供給管21及び外部戻り管22夫々の接続部21a,22aは、外周部に備えられる係止具21b,22bが熱媒受入用接続部10及び熱媒戻し用接続部11の外周部に形成された係合凹部10b,11bに、弾性変形によって自動的に嵌り込み係合して抜け外れを防止する構成となっている。
【0039】
そして、この床暖房パネルでは、複数の板状基材1のうち、熱媒ヘッダ4が設けられる板状基材1における端部側部分Tが、その板状基材1における端部側部分T以外の本体部分Hに対して折れ曲がり自在に構成されている。又、前記熱媒流通管2が、前記端部側部分Tと前記本体部分Hとの折れ曲がり箇所において、その折れ曲がり線Lに沿う姿勢となるように、折れ曲がり箇所の管路長手方向の両側箇所の夫々を湾曲させる状態で備えられている。
【0040】
そして、前記板状基材1における外周部のうちの熱媒ヘッダ4が位置する1辺23からそれに対向する辺24に向かう直線状となる直線状管路部分2aを備えた複数の熱媒流通管2が、前記1辺23の辺長手方向に沿って設定間隔をあけて並ぶ状態で備えられ、前記板状基材1における前記端部側部分Tが、複数の熱媒流通管2の直線状管路部分2aに対して交差する方向の折れ曲がり線Lに沿って折れ曲がるように構成されている。前記折れ曲がり線Lは、複数の熱媒流通管2の直線状経路部分2aにおける管路長手方向と直交する方向に対して傾斜する斜め姿勢となる状態で形成されている。
【0041】
すなわち、熱媒ヘッダ4が設けられる板状基材1が、前記端部側部分Tとその端部側部分T以外の本体部分Hとに分割形成されており、板状基材1同士を接続する接続箇所と同様にして、前記複数の熱媒流通管2が、端部側部分Tと本体部分Hとにわたって連なる状態で配設される構成となっている。前記複数の熱媒流通管2は、端部側部分Tと本体部分Hが分離して折れ曲がる箇所においては、図4に示すように、折れ曲がるときに無理な力がかかり損傷することがないように、管路軸芯方向が折れ曲がり線Lにほぼ沿うような姿勢となるように湾曲させる構成となっている。しかも、そのように熱媒流通管2が湾曲する状態で備えられる箇所において、前記端部側部分Tと本体部分Hの接続用端面には、図13に示すように、端部側部分Tと本体部分Hが密接するように接続させるときに、湾曲している熱媒流通管2が入り込むことが可能な退避用の凹部25が形成されている。
【0042】

The heating medium header for a floor heating panel having the above configuration supplies the heating medium supplied from the heat source through the external supply pipe to the plurality of heating medium distribution pipes provided in the floor heating panel, and supplies the plurality of heats. It is provided to connect the external supply pipe and the external return pipe to the plurality of heat medium flow pipes so that the heat medium returning through the medium flow pipes is joined and returned to the heat source through the external return pipe. However, as such a heating medium header for a floor heating panel, there has conventionally been one configured as follows.

[Problems to be solved by the invention]
In recent years, for example, there is a demand for reducing the level difference between a floor on which a floor heating panel is installed and a sill due to a demand for barrier-free buildings. For this reason, in order to suppress that a floor heating panel protrudes upwards rather than a sill when it installs on a floor, the request | requirement of the thickness reduction which makes a floor heating panel thin is increasing.
[0006]
The floor heating panel can reduce the thickness of the panel by reducing the diameter of the heat medium flow pipe provided in the interior of the floor heating panel. At that time, it is simply reduced in diameter without changing the number of heat medium flow pipes. Since the heat medium flow rate, that is, the amount of heat medium supplied to the heat medium flow pipe is reduced, the number of small diameter heat medium flow pipes is increased and connected in parallel to the heat medium header for the floor heating panel. As a result, the heating medium supply amount can be secured. That is, the floor heating panel can be thinned while ensuring the heat medium supply amount by reducing the diameter of the heat medium flow pipe and increasing the number of the heat medium flow pipes.
[0007]
In order to reduce the thickness of the floor heating panel, it is necessary to reduce the thickness of the header body made of a plate-like block body and to reduce the thickness of the heating medium header for the floor heating panel. In order to reduce the thickness of the header body, the heat medium supply communication path and the heat medium return communication path provided in the header body have a small diameter, but the heat formed as one path The passage resistance of the communication passage for supplying the medium and the communication passage for returning the heat medium is increased. Due to the increase in passage resistance, the amount of heat medium that can be circulated and supplied from the heat source to the floor heating panel is reduced. There was a risk that the ability would decrease.
[0008]
The present invention has been made paying attention to such a point, and an object thereof is to provide a heating medium header for a floor heating panel capable of reducing the thickness of the floor heating panel without reducing the heating capacity. is there.

Since the heat medium supply passages for the plurality of communication passage configurations have a small diameter and a small passage area, a large passage area is ensured for the entire heat medium supply communication passage. And the passage resistance isincreaseTherefore, it is possible to secure a sufficient amount of heat medium supply that can be circulated and supplied from the heat source to the floor heating panel. In addition, since the heating medium supply path for each communication path configuration has a small diameter, it is possible to reduce the thickness of the header body.
[0011]
  In addition, for the heat medium return communication path formed inside the header body, in the same manner as the heat medium supply communication path, a plurality of communication path configuration heat medium return paths are arranged in the thickness direction of the header body. Since it is configured in a state of being arranged side by side along an orthogonal or almost orthogonal direction, even if each of the plurality of communication medium configuration heat medium return paths has a small diameter and a small passage area, The return communication passage as a whole secures a large passage area and reduces passage resistance.increaseTherefore, it is possible to secure a sufficient amount of heat medium supply that can be circulated and supplied from the heat source to the floor heating panel.

Similarly, in the return path of the heat medium, the length of the path of the communication path for returning the heat medium from a plurality of heat medium supply parts distributed and arranged on both the left and right sides in the length direction of the path of the return path of the heat medium. Since the merging is performed while flowing toward the heat medium return connection portion located at the center position in the direction, the path length from the plurality of heat medium discharge portions to the heat medium return connection portion can be shortened.
[0016]
Therefore, in each of the heat medium supply communication path and the heat medium return communication path, the path length through which the heat medium passes can be shortened to reduce the path resistance.
[0017]
