従来のヒートパイプ用パイプは、第1図に示すように、
パイプ本体1の一端部を先細り状に絞って突出状の小径
口部2を形成し、間部2内に作動流体注入管2をはめ込
んで固着したものが用いられていた。The conventional heat pipe pipe is as shown in Fig. 1.
One end of a pipe main body 1 was tapered to form a protruding small-diameter opening 2, and a working fluid injection pipe 2 was fitted into the gap 2 and fixed therein.
しかしこのような形状に絞り加工を行なう場合、絞り加
工部は管長方向にある程度の長さAを必要とし、そのた
めヒートパイプを主体とする熱回収装置等をコンパクト
なものとすることができないうらみがあった。However, when drawing into such a shape, the drawing part requires a certain length A in the longitudinal direction of the pipe, which makes it impossible to make a heat recovery device based on a heat pipe compact. there were.
またこの場合、小径口部2は注入管3の嵌入を容易にす
るために、先端をフレア状にする必要があり、そのため
加工工程が多くてコスト高をまねいた。Further, in this case, the tip of the small-diameter opening 2 needs to be flared in order to facilitate insertion of the injection tube 3, which requires many processing steps and increases costs.
この考案は上記のような点に鑑みてなされたもので、ヒ
ートパイプを用いた装置のコンパクト化およびコストダ
ウンを果すことのできるヒートパイプ用パイプを提供す
ることを目的とする。This invention was made in view of the above points, and aims to provide a pipe for a heat pipe that can make a device using a heat pipe more compact and reduce costs.
以下、この考案を図示の実施例により具体的に説明する
。This invention will be explained in detail below with reference to illustrated embodiments.
第2図において、パイプ本体11の一端部の管壁は、該
一端部の軸心部にパイプ本体より小径の同他端向き突口
部12を形成するようにスピニング加工によって湾曲さ
れている。In FIG. 2, the pipe wall at one end of the pipe body 11 is curved by spinning so as to form a protrusion 12 at the axial center of the one end facing toward the other end, which has a smaller diameter than the pipe body.
そして該突口部12内に作動流体注入管13の一端部が
、密にはめこまれて、溶接によって固着されている。One end of the working fluid injection pipe 13 is tightly fitted into the protrusion 12 and fixed by welding.
第3図はスピニング加工工具を示すもので、工具21の
凹状加工面22は中央に突起23を有する。FIG. 3 shows a spinning tool, in which the concave processing surface 22 of the tool 21 has a protrusion 23 in the center.
そして加工面22に回転するパイプ本体11が押付けら
れ、その結果摩擦熱によってパイプ本体11の圧接端部
が軟化温度に熱せられ、第2図に示すようなスピニング
加工が施こされる。Then, the rotating pipe body 11 is pressed against the processing surface 22, and as a result, the pressed end of the pipe body 11 is heated to a softening temperature by frictional heat, and spinning processing as shown in FIG. 2 is performed.
パイプの材質としてはアルミニウム、銅、ニッケル、ス
テンレス鋼などが挙げられる。Examples of the material of the pipe include aluminum, copper, nickel, and stainless steel.
パイプの他端部はスピニング加工により絞られ、形成さ
れた小口が溶接により閉じられている。The other end of the pipe is narrowed by spinning, and the opening is closed by welding.
注入管13は作動流体の注入後、長さの中央部にて押し
つぶされ、さらに先端部にて溶接によって閉じられる。After injection of the working fluid, the injection tube 13 is crushed at the center of its length and further closed by welding at the tip.
この考案によるヒートパイプ用パイプは、パイプ本体の
一端部の管壁が該一端部の軸心部にパイプ本体より小径
の同他端向き突口部を形成するように湾曲され、該炎口
部内に作動流体注入管の一端部が密にはめ込まれて固着
されたものであるので、以下のような効果を奏する。In the heat pipe pipe according to this invention, the pipe wall at one end of the pipe body is curved so as to form a protruding part facing the same end with a diameter smaller than that of the pipe body at the axial center of the one end part, and Since one end of the working fluid injection pipe is tightly fitted and fixed to the holder, the following effects can be achieved.
(イ)湾曲状の他端向き突口部を形成することにより、
スピニング加工部の管間方向の長さBを短かくすること
ができ、その結果ヒートパイプの長さも短かくすること
ができて、これを組込んだ熱回収装置等をコンパクトな
ものとすることができる。(a) By forming a curved protrusion facing the other end,
It is possible to shorten the length B of the spinning part in the inter-pipe direction, and as a result, the length of the heat pipe can also be shortened, and a heat recovery device incorporating this can be made compact. Can be done.
(ロ)湾曲状の他端向き炎口部を形成した結果、小径部
と作動流体注入管との嵌合部において外側端部に間隙が
形成され、これが両者の溶接時に溶着金属のタマリとな
る。(b) As a result of forming the curved flame port facing the other end, a gap is formed at the outer end at the fitting part between the small diameter part and the working fluid injection pipe, and this becomes a clump of weld metal when welding the two. .
したがって両者の溶接を強固かつ確実なものとすること
ができる。Therefore, the welding between the two can be made strong and reliable.
(ハ)他端向き炎口部の形成によって、第1図に示す従
来品に比べてヒートパイプ構成後の耐圧性を優れたもの
とすることができる。(c) By forming the flame port facing the other end, the pressure resistance after forming the heat pipe can be made superior to that of the conventional product shown in FIG.
(ニ)第1図に示す従来品の場合に比べて、加工工数が
少なくてすむため、ヒートパイプのコストダウンを果す
ことができる。(d) Compared to the conventional product shown in FIG. 1, the number of processing steps is reduced, so the cost of the heat pipe can be reduced.
