Description

【０００１】
【発明の属する技術分野】
本発明はアルミニューム製熱交換器に関し、特にコアに対してヘッダがろう付け中に傾くことを防止したものに関する。
【０００２】
【従来の技術】
熱交換器はフィンとチューブとによりコアを構成し、コアの両側にサポートを配置し、コアの上下に一対のヘッダを配置して、夫々のチューブをヘッダに連通する。そして互いに接触する少なくとも一方の部品表面には予めろう材が被覆されたものを用い、全体を組立てた状態で高温の炉内に挿入し、ろう材を溶融すると共にそれを冷却固化することにより、各部品間を一体的に且つ液密にろう付け固定するものである。
このようなアルミニューム製熱交換器のろう付けは、ろう付けの中に各部品間の相対位置が位置ずれしないように、一対のサポート材間を締結治具で固定していた。
【０００３】
なお、ヘッダがヘッダプレートとヘッダ本体とを有するものにおいては、チューブ端とヘッダプレートとの間をカシメにより固定することにより、ヘッダがコアに対して傾くことはなかった。
しかしながらヘッダ本体がパイプ材からなり、その両端に端蓋を設けたものにおいては、チューブ端をヘッダ本体のチューブ挿通孔にカシメ固定することができない。この場合には、コアとヘッダとの間に何らかの位置決め治具を設けざるを得ない。
【０００４】
【発明が解決しようとする課題】
ろう付け中に、ヘッダがコアに対して傾くのを防止する治具を取付けることは極めて面倒であり、量産性に欠ける欠点があった。また、ヘッダプレートとチューブの開口端との間を拡開固定する作業も面倒であった。
そこで本発明は、各部品どうしで互いに拘束することによりヘッダのコアに対する首振りを拘束できるようにした熱交換器を提供することを課題とする。

【発明の実施の形態】
次に、図面に基づいて本発明の各実施の形態につき説明する。
図１は本発明の第１の実施の形態を示す熱交換器の要部斜視図であり、図２は図１のＩＩ−ＩＩ矢視断面図である。
このアルミニューム製熱交換器は、方形パイプで形成されたヘッダ本体５の両端（右側を省略）に一対の端蓋６が嵌着される。端蓋６は周縁に縁部を設けた皿状に形成され、その皿状凹部外周がヘッダ本体５の開口に整合する。端蓋６のサポート４側にはその中央に舌片状の係合部７が突出されている。また、ヘッダ本体５には多数の偏平孔が並列されると共に、その長手方向両端位置にはサポート４用の偏平孔１２が穿設されている。
【０００９】

また、偏平チューブ１の両端部も夫々ヘッダ本体５の偏平孔に嵌着される。
なお、各部品は互いに接触する少なくとも一方側に予めろう材が被覆されたものが用いられる。
【００１０】
そして左右一対のサポート４間は、図示しない締結治具で幅方向に締結固定した状態で、熱交換器組立体が高温の炉内に挿入され、予め被覆されたろう材を溶融し次いでそれを冷却固化することにより、各部品間を一体的にろう付け固定するものである。このとき、係合部７がＵ字状部８のスリット９に嵌着された状態にあるため、端蓋６とヘッダ本体５とで形成されたヘッダ１０はコア３に対して位置決めされ、傾くことがない。即ち、ろう付け中にヘッダ１０がコア３に対して首振りを行うことなく正確に各部品間がろう付けされる。
【００１１】
次に、図３は本発明の第２の実施の形態を示し、この例が図１のそれと異なる点は、端蓋６の両側に一対の係合部７ａ，７ｂが突設され、その係合部７ａ，７ｂによってサポート４のＵ字状部８の両側を挟持するように位置決めしたことである。このようにすることにより、ろう付け中にヘッダ１０がコア３に対して首振りすることなく正確に位置決めされるので、信頼性の高い熱交換器となり得る。
【００１２】
次に、図４は本発明の第３の実施の形態を示し、この例では端蓋６の外周に爪部１３が折り曲げ形成され、それによって端蓋６がヘッダ本体５の開口端に嵌着する。そしてサポート４のＵ字状部８にはスリット９が設けられ、そのスリット９に係合部７が嵌着し、係合部７の両側がスリット９の開口縁に止着されている。
このように組立てることにより、ろう付け中にヘッダ１０がコア３に対して傾くことを防止できる。
【００１３】
【発明の作用・効果】
本発明の熱交換器は、予め部品表面に被覆されたろう材を炉内で溶融させて各部品間をろう付けするアルミニューム製熱交換器において、端蓋６の係合部７がサポート４のＵ字状部８に設けたスリット９に嵌着することにより、ヘッダ１０がコア３に対して首振りすることを拘束した状態でろう付けがされるものであるから、ろう付け時にヘッダ１０がコア３に対して傾くことを防止し、信頼性の高い熱交換器を提供できる。
【００１４】
また請求項２に記載の本発明によれば、端蓋６の一対の係合部７ａ，７ｂがサポート４のＵ字状部８の両側を挟持するように嵌着して、ヘッダ１０がコア３に対して首振りすることを拘束した状態でろう付けされるものであるから、ろう付け時にヘッダ１０がコア３に対して傾くことを防止し、量産性に優れ且つ精度の良い熱交換器を提供できる。
【００１５】
さらに請求項３に記載の本発明によれば、ヘッダ本体５がパイプ材からなり、そのサポート４のＵ字状部８の先端部１１がヘッダ本体５の偏平孔１２に嵌着されたものであるから、サポート４とヘッダ本体５とが相互に位置決めされるため、ろう付け中にヘッダ１０がコア３に対して傾くことをさらに有効に防止できる。

BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a main part of a heat exchanger according to a first embodiment of the present invention, and FIG. 2 is a sectional view taken along the line II-II of FIG.
In this aluminum heat exchanger, a pair of end covers 6 are fitted to both ends (the right side is omitted) of a header body 5 formed of a square pipe. The end cover 6 is formed in a dish shape having an edge on the periphery, and the outer periphery of the dish-shaped concave portion is aligned with the opening of the header body 5. On the support 4 side of the end cover 6, a tongue-shaped engaging portion 7 projects at the center thereof. A number of flat holes are arranged in the header body 5 and flat holes 12 for the support 4 are formed at both ends in the longitudinal direction.
[0009]
The core 3 has a number of flat tubes 1 and corrugated fins 2 disposed between the flat tubes 1. Supports 4 are arranged on both sides of the core 3. The support 4 is formed in a U-shape in cross section, and both ends thereof are bent back to the outer surface side, and a U-shaped portion 8 is provided there. Further, the U-shaped portion 8 is raised parallel to the flat tube 1. Then, the tip 11 is fitted into the flat hole 12 of the header body 5.
Also, both ends of the flat tube 1 are fitted into the flat holes of the header body 5 respectively.
In addition, each component is used in such a manner that at least one side in contact with each other is coated with a brazing material in advance.
[0010]
A heat exchanger assembly is inserted into a high-temperature furnace between the pair of left and right supports 4 while being fastened and fixed in the width direction by a fastening jig (not shown) to melt the pre-coated brazing material and then cool it. By solidifying, the components are integrally brazed and fixed. At this time, since the engaging portion 7 is fitted in the slit 9 of the U-shaped portion 8, the header 10 formed by the end cover 6 and the header body 5 is positioned with respect to the core 3 and tilts. Nothing. That is, the components are brazed accurately without the header 10 swinging with respect to the core 3 during brazing.
[0011]
Next, FIG. 3 shows a second embodiment of the present invention. This embodiment is different from that of FIG. The positioning is such that both sides of the U-shaped portion 8 of the support 4 are sandwiched by the joint portions 7a and 7b. In this way, since the header 10 is accurately positioned without swinging with respect to the core 3 during brazing, a highly reliable heat exchanger can be obtained.
[0012]
Next, FIG. 4 shows a third embodiment of the present invention. In this example, a claw portion 13 is formed by bending the outer periphery of the end cover 6 so that the end cover 6 is fitted to the open end of the header body 5. I do. A slit 9 is provided in the U-shaped portion 8 of the support 4, and an engaging portion 7 is fitted into the slit 9, and both sides of the engaging portion 7 are fixed to an opening edge of the slit 9.
