しかしながら、特許文献１〜３記載の発明では、総アルミニウム製のラジエータをろう付けする際、特に熱交換部の各エレメント部を構成するアウタシェル、インナーフィン、ロアシェルの三者の接合個所にろう付け不良が発生し易いため、熱交換部をエレメント部の積層方向内側に加圧して所定ピッチにするような治具を使用しなければならず、その脱着に大変手間と時間がかかり、この種のオイルクーラ内蔵ラジエータの効率的な生産を阻害しているという問題点があった。   However, in the inventions described in Patent Documents 1 to 3, when brazing a radiator made of total aluminum, in particular, brazing failure is caused at the joint portion of the outer shell, inner fin, and lower shell constituting each element portion of the heat exchanging portion. Therefore, it is necessary to use a jig that presses the heat exchange part inside the stacking direction of the element part to make a predetermined pitch. There was a problem that the efficient production of radiators with built-in coolers was hindered.

さらに、タンク内のオイルクーラに熱が伝わりにくいため、オイルクーラがスムーズに昇温しないという問題点があった。
なお、ろう付けの時間を延ばすとラジエータのチューブの亜鉛拡散が進行して該ラジエータチューブの耐食性が低下する虞があるため好ましくない。 Furthermore, since heat is not easily transmitted to the oil cooler in the tank, there is a problem that the oil cooler does not rise in temperature smoothly.
It is not preferable to extend the brazing time because zinc diffusion in the radiator tube may progress and the corrosion resistance of the radiator tube may decrease.

また、前記タンク１ｂの内部には後述するオイルクーラ６が収容されており、該オイルクーラ６を含む全ての構成部品がアルミニウム製である。 As shown in FIG. 1, the radiator with a built-in oil cooler of this embodiment includes a pair of seat plates 2a and 2b on which tanks 1a and 1b are mounted, a tube 3 disposed between the seat plates 2a and 2b, and The corrugated fin 4 and the reinforcements 5a and 5b that connect and reinforce both ends of the seat plates 2a and 2b are mainly configured.
An oil cooler 6 to be described later is accommodated in the tank 1b, and all components including the oil cooler 6 are made of aluminum.

図２〜４に示すように、オイルクーラ６は、各エレメント部７の両端部に形成された筒状部７ａ同士がそれぞれ連通した状態で複数積層された熱交換部８と、タンク１ｂの接続パイプ取付孔O3,O3からそれぞれパイプコネクタ9,9を介して前記熱交換部８に連結されることにより、該熱交換部８の両端部にそれぞれ形成された空間Ｏに連通する一対の接続パイプP1,P2とを主要な構成としている。   As shown in FIGS. 2 to 4, the oil cooler 6 has a connection between the tank 1 b and the heat exchanging unit 8, in which a plurality of the cylindrical portions 7 a formed at both ends of each element portion 7 are in communication with each other. A pair of connection pipes communicating with the space O respectively formed at both ends of the heat exchange part 8 by being connected to the heat exchange part 8 from the pipe mounting holes O3 and O3 via the pipe connectors 9 and 9, respectively. P1 and P2 are the main components.

前記タンク１ｂは、互いの開口端部10,11同士を嵌合させて矩形断面形状となるように形成されるコ字状断面形状の分割部１２（第１分割部に相当）と分割部１３（第２分割部に相当）から構成され、タンク１ｂの対向する側壁16,17のうち、側壁１６の内側にはタンク１ｂの長手方向に延設された複数（本実施例では５箇所）のビード溝１８ａが形成され、一方、側壁１７の内側にも前記側壁１６と同様にビード溝１８ｂが複数形成されている。   The tank 1b has a U-shaped cross-section divided portion 12 (corresponding to a first divided portion) and a divided portion 13 which are formed so as to have a rectangular cross-sectional shape by fitting the opening end portions 10 and 11 to each other. (Corresponding to the second divided portion), among the opposing side walls 16, 17 of the tank 1b, a plurality of (five places in this embodiment) extending in the longitudinal direction of the tank 1b inside the side wall 16 A bead groove 18 a is formed. On the other hand, a plurality of bead grooves 18 b are also formed inside the side wall 17 in the same manner as the side wall 16.

そして、前記熱交換部８の積層方向の最外端となるエレメント部14,15は前記ビード溝18a,18b（加圧手段）に密着した状態で固定されている。   And the element parts 14 and 15 used as the outermost end of the heat exchange part 8 in the laminating direction are fixed in close contact with the bead grooves 18a and 18b (pressure means).

また、タンク１ｂ及びオイルクーラ６を構成する各部品の接触部には少なくとも一方側にろう材が被覆されたブレージングシート（クラッド材）が用いられている。   In addition, a brazing sheet (clad material) coated with a brazing material on at least one side is used at the contact portion of each component constituting the tank 1b and the oil cooler 6.

このようなオイルクーラ内蔵ラジエータを仮組みするには、先ず、図５（ａ）に示すように、複数のブレードＢ（図６参照）を有してその周縁が立ち上げられて皿状に形成され、且つ、両端部にバーリング加工で形成された筒状部７ａを有する一対のアッパシェル７ｂ及びロアシェル７ｃを、波状のインナーフィン７ｄを介装した状態で互いに圧入またはカシメ固定することによりエレメント部７を形成する。   In order to temporarily assemble such an oil cooler built-in radiator, first, as shown in FIG. 5 (a), it has a plurality of blades B (see FIG. 6) and its peripheral edge is raised to form a dish shape. The element portion 7 is formed by press-fitting or caulking and fixing a pair of upper shell 7b and lower shell 7c having a cylindrical portion 7a formed by burring at both ends with a wave-like inner fin 7d interposed therebetween. Form.

続いて、図５（ｂ）に示すように、各エレメント部７を円筒状のシート１９を介した状態で複数（本実施例では５層）積層することにより熱交換部８を形成する。
なお、前記熱交換部８の積層方向の最外端となるエレメント部14,15のうち、エレメント部１４の筒状部７ａには他のシート１９よりも肉厚のシート１９ａが積層され、エレメント部１５のロアシェル７ｃは筒状部７ａが省略されている。 Subsequently, as shown in FIG. 5B, the heat exchange section 8 is formed by laminating a plurality (5 layers in this embodiment) of each element section 7 with the cylindrical sheet 19 interposed therebetween.
Of the element parts 14 and 15 which are the outermost ends in the stacking direction of the heat exchange part 8, a sheet 19a thicker than the other sheets 19 is stacked on the tubular part 7a of the element part 14, and the element The cylindrical part 7a is omitted from the lower shell 7c of the part 15.

次に、図６、図７（ａ）に示すように、分割部１２の開口端部10,10同士を外側に幾分開いた状態でエレメント部１４の筒状部7a,7aと接続パイプ取付孔O3,O3の中心を一致させた状態とし、ここに接続パイプP1,P2が圧入されたパイプコネクタ9,9をエレメント部１４の筒状部7a,7aに圧入またはカシメ固定する。   Next, as shown in FIGS. 6 and 7 (a), the cylindrical portions 7a and 7a of the element portion 14 are attached to the connecting pipe and the open end portions 10 and 10 of the dividing portion 12 are somewhat opened outward. The centers of the holes O3 and O3 are made to coincide with each other, and the pipe connectors 9 and 9 into which the connection pipes P1 and P2 are press-fitted are press-fitted or caulked and fixed to the cylindrical parts 7a and 7a of the element part 14, respectively.

次に、図６、図７（ｂ）に示すように前記分割部１２の開口端部10,10同士を閉じる方向に変形させながら分割部１３の開口端部11,11に圧入して嵌合させることにより両者を固定する。
この際、前記タンク１ｂの対向する側壁16,17に形成されたビード溝18a,18bが、前記熱交換部８を積層方向内側に適正に加圧し、結果、各エレメント部７におけるアッパシェル７ｂ、インナーフィン７ｄ、ロアシェル７ｃを密着した状態で所定ピッチに仮組することができる。 Next, as shown in FIG. 6 and FIG. 7B, the open end portions 10, 10 of the divided portion 12 are deformed in the closing direction, and are fitted into the open end portions 11, 11 of the divided portion 13. To fix both.
At this time, the bead grooves 18a and 18b formed on the opposing side walls 16 and 17 of the tank 1b appropriately pressurize the heat exchanging portion 8 in the stacking direction. As a result, the upper shell 7b and the inner The fins 7d and the lower shell 7c can be temporarily assembled at a predetermined pitch in a close contact state.

続いて、分割部12,13の開口端部10,11同士をタンク１ｂの長手方向に数箇所に亙ってカシメ固定することによりオイルクーラ内蔵ラジエータの仮組みを終了する。
具体的には、図８に示すように、予め開口端部１０にはカシメ固定する個所に開口部Ｏ２が形成され、両開口端部10,11を重ねた状態で円柱状のパンチ２０と、該パンチ２０よりも幾分小径のパンチ２１で両開口端部10,11をプレス加工することによりカシメ固定する。なお、両者の固定は別の方法を用いても良い。 Subsequently, the temporary assembly of the radiator with the built-in oil cooler is completed by caulking and fixing the open end portions 10 and 11 of the divided portions 12 and 13 in several places in the longitudinal direction of the tank 1b.
Specifically, as shown in FIG. 8, the opening end 10 is previously formed with an opening O2 at a location to be caulked and fixed, and the cylindrical punch 20 with both the opening ends 10 and 11 overlapped, The opening ends 10 and 11 are pressed by a punch 21 having a diameter slightly smaller than that of the punch 20 and fixed by caulking. In addition, you may use another method for both fixation.

このように仮組みされたオイルクーラ内蔵ラジエータは、前記タンク１ｂの両端部に図外のパッチが嵌合されて内部にオイルクーラ６が収容された状態で図外の加熱炉で熱処理されることにより、ラジエータの各部と共にタンク１ｂとオイルクーラ６の各部の接触部がろう付けされ、結果、接続パイプＰ１からエンジンやＡＴのオイルを流入させて熱交換部８のエレメント部７内を長手方向に流通させて該オイルとタンク１ｂ１ｂ内の冷却水を熱交換させた後、接続パイプＰ２から排出する冷却回路となる。   The oil cooler built-in radiator thus temporarily assembled is heat-treated in a heating furnace (not shown) in a state where a patch (not shown) is fitted to both ends of the tank 1b and the oil cooler 6 is accommodated therein. As a result, the contact portion of each part of the tank 1b and the oil cooler 6 is brazed together with each part of the radiator, and as a result, the oil of the engine or AT flows from the connection pipe P1 in the element part 7 of the heat exchange part 8 in the longitudinal direction. After the oil is circulated and the oil in the tank 1b1b is subjected to heat exchange, the cooling circuit is discharged from the connection pipe P2.

そして、前述したように、ビード溝18a,18bは熱交換部８を積層方向内側に適正に加圧しているため、各エレメント部７におけるアッパシェル７ｂ、インナーフィン７ｄ、ロアシェル７ｃが密着した状態となり、熱交換部８のろう付けを良好に行うことができる。   As described above, since the bead grooves 18a and 18b pressurize the heat exchanging portion 8 appropriately inward in the stacking direction, the upper shell 7b, the inner fin 7d, and the lower shell 7c in each element portion 7 are in close contact with each other, The heat exchange part 8 can be brazed well.

また、前記熱処理の際に加熱炉内の熱がビード溝18a,18bを介して熱交換部８へ効率良く伝達し、これによりオイルクーラ６全体をスムーズに昇温させて良好なろう付けを行うことができる。   Further, during the heat treatment, the heat in the heating furnace is efficiently transferred to the heat exchanging portion 8 through the bead grooves 18a and 18b, thereby smoothly raising the temperature of the entire oil cooler 6 and performing good brazing. be able to.

以上、本発明の実施例を説明してきたが、本発明の具体的構成は本実施例に限定されるものではなく、発明の要旨を逸脱しない範囲の設計変更などがあっても本発明に含まれる。   Although the embodiments of the present invention have been described above, the specific configuration of the present invention is not limited to the embodiments, and the present invention includes any design changes that do not depart from the gist of the invention. It is.
