【考案の詳細な説明】
本考案は、加熱流体が流通する熱交換器本体
と、該本体外壁に接触して設けられた被加熱流体
流通用の熱交換パイプと、からなる熱交換器に関
し、特に前記熱交換器本体の構造の改良に関す
る。[Detailed Description of the Invention] The present invention relates to a heat exchanger comprising a heat exchanger body through which heated fluid flows, and a heat exchange pipe for distributing the heated fluid provided in contact with the outer wall of the body. In particular, it relates to improvements in the structure of the heat exchanger body.
この種の熱交換器として従来第１図に示す構造
のものが知られている。 A conventional heat exchanger of this type has a structure shown in FIG. 1.
即ち、熱交換器本体１はアルミニウム等の金属
材料を押し出し成形して筒状に構成され、その外
周壁に一体成形した溝部３に銅製パイプからなる
熱交換パイプ４を嵌入して密着させた構成であ
り、前記熱交換器本体１の上・下内壁には、伝熱
面積を拡大するための伝熱フイン２が通路方向に
沿つて前記金属材料の押し出し成形時に一体成形
されている。 That is, the heat exchanger main body 1 is formed into a cylindrical shape by extruding a metal material such as aluminum, and has a structure in which a heat exchange pipe 4 made of a copper pipe is fitted into a groove 3 integrally molded on the outer circumferential wall of the heat exchanger main body 1 and brought into close contact with the heat exchanger main body 1. Heat transfer fins 2 for enlarging the heat transfer area are integrally formed on the upper and lower inner walls of the heat exchanger main body 1 along the passage direction during extrusion molding of the metal material.
かかる熱交換器において、熱交換器本体１内に
は加熱流体としての燃焼器による燃焼ガスが導入
され、該本体１内の上流側空間が前記燃焼器によ
る火炎形成部即ち燃焼空間となる。 In such a heat exchanger, combustion gas from a combustor as a heating fluid is introduced into a heat exchanger main body 1, and an upstream space within the main body 1 becomes a flame forming part, that is, a combustion space by the combustor.
このため熱交換器本体１内の上流側空間におい
ては、火炎が伝熱フイン２にダイレクトに接触し
て冷却され一酸化炭素が発生する等、燃焼性に悪
影響を及ぼす恐れがある。 Therefore, in the upstream space within the heat exchanger main body 1, the flame may come into direct contact with the heat transfer fins 2, be cooled, and generate carbon monoxide, which may have an adverse effect on combustibility.
従つて、熱交換器本体１内上流側空間に位置す
る伝熱フイン２の一部を除去して、該フイン２の
ない燃焼空間を形成する必要があるが、熱交換器
本体１が押し出し成形によつて構成されるため長
手方向に同一形状で連続しており、この押し出し
成形時に伝熱フイン２の切除部を形成することは
不可能である。 Therefore, it is necessary to remove a part of the heat transfer fins 2 located in the upstream space within the heat exchanger body 1 to form a combustion space without the fins 2. Since the heat transfer fins 2 are constructed by the heat transfer fins 2, they are continuous in the same shape in the longitudinal direction, and it is impossible to form a cutout portion of the heat transfer fins 2 during extrusion molding.
このため従来は、伝熱フイン２に切削機械加工
を施して、第１図Ａに示すような切除部２Ａを形
成しているが、このような機械加工は作業上面倒
であると共に加工時間も長くかかり製作コストが
高くなるという欠点があつた。 For this reason, conventionally, the heat transfer fin 2 is subjected to cutting machining to form a cutout part 2A as shown in FIG. The disadvantage was that it took a long time and the production cost was high.
そこで、本考案は以上のような従来の実情に鑑
み、熱交換器本体を、伝熱フインのある加熱流体
下流側部分と伝熱フインのない加熱流体上流側部
分とに２分割した金属材料の押し出し成形体より
なる構成部材相互の結合体により構成したことに
より、従来の伝熱フインの機械加工による切除部
形成を廃止し、もつて上記従来の欠点を解消して
製作性の向上を図つた熱交換器を提供するもので
ある。 Therefore, in view of the above-mentioned conventional circumstances, the present invention has been developed using a metal material in which the heat exchanger main body is divided into two parts: a heating fluid downstream part with heat transfer fins and a heating fluid upstream part without heat transfer fins. By constructing the heat transfer fin by combining the extruded components, it is possible to eliminate the conventional machining of heat transfer fins to form cutouts, eliminate the above-mentioned conventional drawbacks, and improve manufacturability. It provides a heat exchanger.
以下、本考案の一実施例を第２図に基づいて説
明する。 An embodiment of the present invention will be described below with reference to FIG.
図において、１は筒状の熱交換器本体で、内部
には燃焼ガスが流通する通路１Ａが形成されてお
り、８及び９の金属材料の押し出し成形体よりな
る構成部材相互の結合体からなる。 In the figure, 1 is a cylindrical heat exchanger main body, in which a passage 1A through which combustion gas flows is formed, and it is made up of a mutual combination of structural members 8 and 9 made of extruded bodies of metal materials. .
即ち、一方の熱交換器本体構成部材８は熱交換
器本体１の通路１Ａ上流側に位置し、他方の構成
部材９は下流側に位置するもので夫々、相対向す

側熱交換器本体構成部材９の前記溝部３形成側の
相対向する壁内面には、夫々２の伝熱フインが、
相互対向するように内側に延びて押し出し成形に
より一体成形されている。 That is, one heat exchanger main body component 8 is located on the upstream side of the passage 1A of the heat exchanger main body 1, and the other component 9 is located on the downstream side. A groove 3 for tightly supporting a heat exchange pipe 4 made of a copper pipe along the direction of the passage 1A is integrally molded in the longitudinal direction. Two heat transfer fins are provided on the inner surfaces of the opposing walls of the downstream heat exchanger main body component 9 on the side where the groove portion 3 is formed, respectively.
They extend inward so as to face each other and are integrally molded by extrusion molding.
そして、構成部材８，９相互は一側の端面相互
をシール部材１０を介して密着した状態で結合さ
れる。 The structural members 8 and 9 are connected to each other with their end surfaces on one side in close contact with each other via the sealing member 10.
かかる構成によれば、上流側の熱交換器本体構
成部材８内の通路１Ａにはフイン２がなく、ここ
が図示しない燃焼器の火炎形成がなされる燃焼空
間５となるわけである。 According to this configuration, there is no fin 2 in the passage 1A in the upstream heat exchanger main body component 8, and this becomes the combustion space 5 in which the flame of the combustor (not shown) is formed.
即ち、伝熱フイン２を設けた下流側熱交換器本
体構成部材９と伝熱フインのない上流側熱交換器
本体構成部材８とを結合して熱交換器本体１を構

ける必要がなく、面倒な作業を廃止することがで
きる。 That is, by configuring the heat exchanger main body 1 by combining the downstream heat exchanger main body constituent member 9 provided with the heat transfer fins 2 and the upstream heat exchanger main body constituent member 8 without heat transfer fins, it is possible to There is no need to perform machining on the heat transfer fins to create a cutout section of the heat transfer fins, as shown in the figure, and the troublesome work can be eliminated.
この場合、金属材料の押出部材として２種類の
ものが必要となるが押出部材形成用の金型費は比
較的安価なものであるため従来の機械加工による
方法よりも製作費が嵩むことはない。 In this case, two types of metal material extrusion parts are required, but the mold cost for forming the extrusion parts is relatively inexpensive, so the production cost will not be higher than the conventional machining method. .
以上説明したように本考案によれば、加熱流体

の向上を図れ、製作費を安価にできる実用的効果
大なるものである。 As explained above, according to the present invention, the heat exchanger main body through which the heated fluid flows is made of a constituent member made of an extrusion molded body of metal material divided into two parts, and heat transfer fins are extruded on only one of the parts. By providing this, it is possible to easily form parts without heat transfer fins in the heat exchanger body, and it is possible to eliminate the machining that was conventionally performed to provide cutouts on heat transfer fins that cannot be formed by extrusion molding, improving workability. This has a great practical effect of improving the performance and reducing the manufacturing cost.
