Description

【０００１】
【発明の属する技術分野】
本発明は、皿状に形成されたヘッダープレートの長手方向両端にサポート材の端部をカシメにより固定すると共に、熱交換器の各部品を組立て、各部品間をその後一体にろう付け固定するものに関する。
【０００２】
【従来の技術】
量産される熱交換器は、各部品間を組み立てた後に、その相対関係を維持して各部品の接触部間を一体にろう付け固定することにより、熱交換器を完成していた。
即ち、図３に示す如く、一例として偏平なチューブ９とコルゲート型のフィン８とを交互に並列すると共に、その並列方向両端（右側を省略する）位置にサポート材２を配置してコアを組み立てる。そして夫々のチューブ９の両端（下側省略）をヘッダープレート１のチューブ挿通孔１０に挿通すると共に、サポート材２の先端部２ｂをヘッダープレート１の外面側に接触する。
【０００３】
次いでヘッダープレート１の長手方向端部に突設されたサポートかしめ用爪部３をかしめ治具６によりカシメてＵ字状に形成し、サポート材２の先端部２ｂをサポートかしめ用爪部３により挟持固定し、熱交換器を組み立てる。
そして予め互いに接触する各部品の少なくとも一方の表面にろう材を被覆または配置しておき、熱交換器の組立体を高温の炉内に挿入し、ろう材を溶融すると共に次いでそれを冷却固化し、各部品間を一体的にろう付け固定して、熱交換器を完成していた。
【０００４】
【発明が解決しようとする課題】
ヘッダープレート１のサポートかしめ用爪部３によってサポート材２の先端部２ｂを挟持固定するには、かしめ治具６を図３において上下方向に移動し、その先端部のＵ字状内面６ａにより、サポートかしめ用爪部３をＵ字状に折り曲げていた。
ところが、かしめ治具６を下降させてサポートかしめ用爪部３をＵ字状に折り曲げ、その後にかしめ治具６を上方に後退させると、そのかしめ治具６の上昇に伴いＵ字状のサポートかしめ用爪部３自体も僅かに上方に移動し、サポート材２との相対位置がずれる場合がある。
【０００５】
すると、サポート材２とヘッダープレート１との位置決めが正確に行われず、熱交換器の強度を設計値に保てないおそれがある。またヘッダープレート１の端部が僅かに変形し、シール性に問題が生じるおそれがある。
そこで本発明は、係る問題点を簡単な構造で確実に防ぐことができるヘッダープレートとサポート材との固定構造及びその固定方法を提供することを課題とする。
【０００６】
【課題を解決するための手段】
請求項１に記載の本発明は、細長い皿状に形成された金属板の成形体よりなるヘッダープレート（１）　の長手方向の端部外面に、金属板の成形体よりなる細長いサポート材（２）　の端部を固定する構造において、
前記ヘッダープレート（１）　の前記端部の上縁にサポートかしめ用爪部（３）　が突設されると共に、そのサポートかしめ用爪部（３）　に、内面側から外面側に突出するダボ（４）　が曲折形成され、
前記サポート材（２）　の端部に、前記ダボ（４）　に整合する係止孔（５）　が穿設され、
前記サポートかしめ用爪部（３）　が外側にＵ字状に曲折されて、前記ダボ（４）　が前記サポート材（２）　の前記係止孔（５）　に嵌着されてなる熱交換器のヘッダープレートとサポート材との固定構造である。
【０００７】
請求項２に記載の本発明は、細長い皿状に形成された金属板の成形体よりなるヘッダープレート（１）　の長手方向の端部外面に、金属板の成形体よりなる細長いサポート材（２）　の端部を固定する方法において、
前記ヘッダープレート（１）　の前記端部の上縁にサポートかしめ用爪部（３）　を突設すると共に、そのサポートかしめ用爪部（３）　に、内面側から外面側に突出するダボ（４）　を予め曲折形成しておき且つ、
前記サポート材（２）　の端部に、前記ダボ（４）　に整合する係止孔（５）　を穿設しておく工程と、
次いで、先端部がＵ字状内面（６ａ）に形成されたかしめ治具（６）　で、前記サポート材かしめ用爪部（３）　を外側にＵ字状に曲折して、前記ダボ（４）　を前記サポート材（２）　の前記係止孔（５）　に嵌着固定する工程と、
を具備する熱交換器のヘッダープレートとサポート材との固定方法である。
【０００８】
【発明の実施の形態】
次に、図面に基づいて本発明の実施の形態つき説明する。
図１は本発明の熱交換器のヘッダープレートとサポート材との固定構造の要部縦断面図であり、図２はその要部分解斜視略図である。なお、図３の従来技術と同一部品に対しては、図１、図２においても同一の番号を付し、同一の構造部分の説明は省略する。
この例では図２に示す如く、皿状に形成されたヘッダープレート１に多数の偏平なチューブ挿通孔１０が定間隔で並列されると共に、ヘッダープレート１の内周縁には環状溝部１ａが形成されている。そしてヘッダープレート１の全周縁部は立ち上げられると共に、その縁部に多数のタンクかしめ用爪部７が定間隔に一体に立設されている。さらに、ヘッダープレート１の長手方向両端位置（右側を省略）の上縁にはサポートかしめ用爪部３が立設されている。
【０００９】
そのサポートかしめ用爪部３には、断面半円状等のダボ４がその内面側から外面側に塑性変形により突設形成されている。なお、このダボ４はヘッダープレート１の成形時に同時に成形しても、或いはヘッダープレート１の成形後にそれを設けてもよい。
次に、サポート材２は、その上下両端部を除き、その幅方向両縁部に断面Ｌ字状に折曲部２ａが曲折形成されると共に、サポート材２の長手方向両先端部２ｂ（下側を省略）の付根部が僅かに曲折されると共に、その先端部２ｂに複数の係止孔５が穿設される。この係止孔５はサポートかしめ用爪部３のダボ４に整合する。
【００１０】
そこで、先ずサポートかしめ用爪部３をヘッダープレート１の周縁に対しＬ字状（図２）に一旦折り曲げ、次いで図１の如くサポート材２の先端部２ｂをヘッダープレート１の外周に当接する。次いで、かしめ治具６を図において下方に移動することにより、その先端部のＵ字状内面６ａで、サポートかしめ用爪部３をＵ字状に折り曲げる。そしてサポートかしめ用爪部３によりサポート材２の先端部２ｂの外周を挟持すると共に、そのダボ４を係止孔５に嵌入する。この状態で、かしめ治具６を上方に引き抜く。このときダボ４の突部は係止孔５の開口縁に係止されるため、かしめ治具６を上昇しても、サポートかしめ用爪部３が上方に移動することはない。それにより、ヘッダープレート１とサポート材２との相対関係を固定し、両者の位置決めを正確に行うことができる。
【００１１】
このような組立て状態で各部品間を一体にろう付け固定することにより、熱交換器コアを完成する。
次いで、この例では図１に示すプラスチック製のタンク本体１１のフランジ部１１ａがＯリング１２を介しヘッダープレート１の環状溝部１ａに圧入され、その圧入状態でタンクかしめ用爪部７がフランジ部１１ａ側に折り曲げられることにより、タンク本体１１がヘッダープレート１に液密に固定される。
【００１２】
なお、プラスチック製のタンク本体１１の代わりに金属製のタンク本体を用いることもできる。この場合には、環状溝部１ａはタンク本体の金属板の板厚に整合するように形成される。また、タンクかしめ用爪部７は不要である。そして図示しないタンク本体の開口をヘッダープレート１の環状溝部１ａに嵌着し、タンク本体と共に各部品間を一体にろう付け固定すれば足りる。
【００１３】
【発明の作用・効果】
本発明の固定構造及び固定方法は、ヘッダープレート１のサポートかしめ用爪部３が外側にＵ状に折り曲げられ、そこに設けたダボ４がサポート材２の係止孔５に嵌着されるから、サポート材２とヘッダープレート１との位置決めを簡単な構造で確実にすることができる。即ち、予めサポート材２に係止孔５を、サポートかしめ用爪部３にダボ４を設けておき、先端部にＵ字状内面６ａを有するかしめ治具６でサポート材２の長手方向にそれを移動することにより、ヘッダープレート１とサポート材２間を確実に固定することができる。そのとき、かしめ治具６の出入に伴ってサポート材２とヘッダープレート１との相対関係がずれることを防止できる。
そのため、精度の良い熱交換器を提供できる。

TECHNICAL FIELD OF THE INVENTION
The present invention fixes the ends of the support material to both ends in the longitudinal direction of a dish-shaped header plate by caulking, assembles the components of the heat exchanger, and brazes the components together thereafter. About.
[0002]
[Prior art]
In a mass-produced heat exchanger, after assembling the components, the relative relationship is maintained and the contact portions of the components are integrally brazed and fixed to complete the heat exchanger.
That is, as shown in FIG. 3, as an example, a flat tube 9 and a corrugated fin 8 are alternately arranged side by side, and the support material 2 is arranged at both ends (the right side is omitted) of the parallel direction to assemble the core. . Then, both ends (the lower side is omitted) of each tube 9 are inserted into the tube insertion hole 10 of the header plate 1, and the tip 2 b of the support material 2 is brought into contact with the outer surface of the header plate 1.
[0003]
Next, a support caulking claw 3 projecting from the longitudinal end of the header plate 1 is caulked by a caulking jig 6 to form a U-shape, and the tip 2b of the support material 2 is supported by the support caulking claw 3. Hold and fix, and assemble the heat exchanger.
Then, the brazing material is coated or arranged on at least one surface of each part in contact with each other in advance, and the heat exchanger assembly is inserted into a high-temperature furnace, and the brazing material is melted and then cooled and solidified. Then, the components were integrally brazed and fixed to complete the heat exchanger.
[0004]
[Problems to be solved by the invention]
In order to clamp and fix the tip 2b of the support material 2 by the support crimping portion 3 of the header plate 1, the caulking jig 6 is moved up and down in FIG. 3, and the U-shaped inner surface 6a of the tip is used. The support caulking claw 3 was bent in a U-shape.
However, when the caulking jig 6 is lowered to bend the support caulking claw 3 into a U-shape, and then the caulking jig 6 is retracted upward, the U-shaped support is raised with the rise of the caulking jig 6. The caulking claw 3 itself may move slightly upward, and the relative position with respect to the support material 2 may be shifted.
[0005]
Then, the positioning of the support material 2 and the header plate 1 is not performed accurately, and the strength of the heat exchanger may not be maintained at the design value. Further, the end of the header plate 1 may be slightly deformed, and a problem may occur in the sealing performance.
Therefore, an object of the present invention is to provide a fixing structure between a header plate and a support member, which can surely prevent such a problem with a simple structure, and a fixing method therefor.

This is a method of fixing the header plate and the support material of the heat exchanger having the following.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a vertical sectional view of a main part of a fixing structure of a header plate and a support member of a heat exchanger of the present invention, and FIG. 2 is a schematic exploded perspective view of the main part. 1 and 2 are given the same reference numerals in FIGS. 1 and 2 and the description of the same structural parts is omitted.
In this example, as shown in FIG. 2, a number of flat tube insertion holes 10 are arranged at regular intervals in a header plate 1 formed in a dish shape, and an annular groove 1a is formed in the inner peripheral edge of the header plate 1. ing. The entire peripheral edge of the header plate 1 is raised, and a number of tank caulking claws 7 are integrally provided at regular intervals on the edge. Further, support caulking claws 3 are provided upright at the upper edges of the header plate 1 at both ends in the longitudinal direction (the right side is omitted).
[0009]
A dowel 4 having a semicircular cross section or the like is formed on the support caulking claw portion 3 by plastic deformation from its inner surface to its outer surface. The dowel 4 may be formed at the same time as the header plate 1 is formed, or may be provided after the header plate 1 is formed.
Next, the support member 2 is formed with a bent portion 2a having an L-shaped cross section at both edges in the width direction except for both upper and lower ends thereof, and both longitudinal end portions 2b (lower portion) of the support member 2 are formed. (The side is omitted), the base portion is slightly bent, and a plurality of locking holes 5 are formed in the distal end portion 2b. This locking hole 5 is aligned with the dowel 4 of the support caulking claw 3.
[0010]
Therefore, first, the support caulking claw portion 3 is once bent in an L shape (FIG. 2) with respect to the peripheral edge of the header plate 1, and then the tip 2 b of the support material 2 is brought into contact with the outer periphery of the header plate 1 as shown in FIG. Next, by moving the caulking jig 6 downward in the figure, the support caulking claw 3 is bent into a U-shape at the U-shaped inner surface 6a at the tip thereof. Then, the outer periphery of the distal end portion 2b of the support member 2 is clamped by the support caulking claw portion 3, and the dowel 4 is fitted into the locking hole 5. In this state, the caulking jig 6 is pulled out upward. At this time, since the projection of the dowel 4 is locked to the opening edge of the locking hole 5, even if the caulking jig 6 is raised, the support caulking claw 3 does not move upward. Thereby, the relative relationship between the header plate 1 and the support member 2 is fixed, and the positioning of both can be performed accurately.
[0011]
The heat exchanger core is completed by integrally brazing and fixing the components in such an assembled state.
Next, in this example, the flange portion 11a of the plastic tank body 11 shown in FIG. 1 is press-fitted into the annular groove portion 1a of the header plate 1 via the O-ring 12, and in this press-fit state, the tank caulking claw portion 7 is turned into the flange portion 11a. By being bent to the side, the tank main body 11 is fixed to the header plate 1 in a liquid-tight manner.
[0012]
Note that a metal tank main body can be used instead of the plastic tank main body 11. In this case, the annular groove 1a is formed so as to match the thickness of the metal plate of the tank body. Further, the claw portion 7 for caulking the tank is unnecessary. It suffices if the opening of the tank body (not shown) is fitted into the annular groove 1a of the header plate 1 and the components together with the tank body are brazed together.
[0013]
[Action and Effect of the Invention]
According to the fixing structure and the fixing method of the present invention, the support caulking claw portion 3 of the header plate 1 is bent outward in a U-shape, and the dowel 4 provided therein is fitted into the locking hole 5 of the support material 2. The positioning between the support member 2 and the header plate 1 can be ensured with a simple structure. That is, a retaining hole 5 is provided in the support material 2 in advance, and a dowel 4 is provided in the support caulking claw portion 3, and a crimping jig 6 having a U-shaped inner surface 6 a at a tip portion is provided in the longitudinal direction of the support material 2. Is moved, the header plate 1 and the support member 2 can be reliably fixed. At this time, it is possible to prevent the relative relationship between the support member 2 and the header plate 1 from being deviated as the caulking jig 6 moves in and out.
Therefore, an accurate heat exchanger can be provided.
