As a result, the liquid receiver 5 is fixedly supported by the tank 3 in a stable state by the intermediate members 8 and 9 and the holding member 16.

図9に示すように、第1分割部材11内における連通孔11dと連通孔11eとの間には金属製フィルタ17が設けられている。
図12に示すように、金属製フィルタ17は、フィルタ本体部17aと、フランジ部17bと、金属製リング17cから構成されている。
フィルタ本体部17aは、網状の小さな孔を有して下方に開口した有底円筒状に形成されている。

これにより、フィルタ本体部17aの下端部の内側にフランジ部17bの上端部を重ねる一方、外側に金属製リング17cを重ねた状態として、金属製リング17cを内側に加締めることにより、これら三者が固定されている。
As shown in FIG. 9, a metal filter 17 is provided between the communication hole 11 d and the communication hole 11 e in the first divided member 11.

次に、作用を説明する。
[熱交換器の製造について]
このような熱交換器1を製造するには、先ず、熱交換器1全体を仮組みする。
この際、受液器5をタンク3に仮組みするには、先ず、両分割部材11,12を連結して本体13を仮組みした後、その内部に金属製フィルタ17及びブラケット部材19を挿入して配置する。
Next, the operation will be described.
[Production of heat exchanger]
In order to manufacture such a heat exchanger 1, first, the heat exchanger 1 whole is temporarily assembled.
At this time, in order to temporarily assemble the liquid receiver 5 in the tank 3, first, the divided members 11 and 12 are connected and the main body 13 is temporarily assembled, and then the metal filter 17 and the bracket member 19 are inserted therein. And place it.

次に、閉塞部材14を本体13の下方開口端部13aに圧入固定する。   Next, the closing member 14 is press-fitted and fixed to the lower opening end 13 a of the main body 13.

次に、中間部材8,9及び保持部材16を固定部11cの内側に挿入配置した後、両側壁11a,11aを加締めて加締め部11f,11fを形成する。
この際、両側壁11a,11aが中間部材8,9の座部8c,9cの側面に当接して該中間部材8,9を案内することにより、中間部材8,9の前後方向(コア部4の幅方向)の位置決めを正確に行うことができる。
また、中間部材8,9の座部8c,9cと中途部8e,9eがそれぞれ対応する加締め部11f,11fで加締められることにより、中間部材8,9の座部8c,9cを両側壁11a,11aと底部11bに密着させた状態で保持できる。
Next, after the intermediate members 8 and 9 and the holding member 16 are inserted and arranged inside the fixed portion 11c, the side walls 11a and 11a are crimped to form the crimped portions 11f and 11f.
At this time, the side walls 11a, 11a are in contact with the side surfaces of the seat portions 8c, 9c of the intermediate members 8, 9 to guide the intermediate members 8, 9, thereby causing the intermediate members 8, 9 to move in the front-rear direction (core portion 4). Positioning in the width direction) can be performed accurately.
Further, the seat portions 8c and 9c of the intermediate members 8 and 9 and the intermediate portions 8e and 9e are crimped by the corresponding crimping portions 11f and 11f, so that the seat portions 8c and 9c of the intermediate members 8 and 9 are attached to both side walls. It can hold | maintain in the state closely_contact | adhered to 11a and 11a and the bottom part 11b.

これにより、中間部材8,9と固定部11cとの相対位置決めを行うことができ、連通孔8a,9aと連通孔11d,11eとを相対位置決めした状態で中間部材8,9を固定部11cに仮固定できる。
さらに、連通孔11d(11e)の開口径は連通孔8a(9a)の開口径よりも幾分大きく設定されているため、これら両者の上下方向における相対位置ずれは多少許容できる。
同様に、保持部材16においても、中間部材8,9と同様に、固定部11cとの相対位置決めをした状態で仮固定できる。
Thereby, the relative positioning of the intermediate members 8 and 9 and the fixed portion 11c can be performed, and the intermediate members 8 and 9 are fixed to the fixed portion 11c in a state where the communication holes 8a and 9a and the communication holes 11d and 11e are relatively positioned. Can be temporarily fixed.
Furthermore, since the opening diameter of the communication hole 11d (11e) is set to be somewhat larger than the opening diameter of the communication hole 8a (9a), the relative positional deviation in the vertical direction of both of them can be allowed to some extent.
Similarly, the holding member 16 can be temporarily fixed in a state where the holding member 16 is relatively positioned with respect to the fixing portion 11c, similarly to the intermediate members 8 and 9.

次に、受液器5と共に中間部材8,9の挿入部8b,9b及び保持部材16の挿入部16bをタンク3のそれぞれ対応する連通孔10k,10m,10nに挿通し固定して、受液器5をタンク3に仮組みする。
これにより、閉塞部材15及び収容部材20を除く熱交換器1の全ての構成部材の仮組みが終了する。
Next, the insertion portions 8b and 9b of the intermediate members 8 and 9 and the insertion portion 16b of the holding member 16 together with the liquid receiver 5 are inserted into and fixed to the corresponding communication holes 10k, 10m and 10n of the tank 3, respectively. The vessel 5 is temporarily assembled to the tank 3.
Thereby, temporary assembly of all the structural members of the heat exchanger 1 except the closing member 15 and the housing member 20 is completed.

次に、このように仮組みされた熱交換器1を加熱炉内で熱処理することにより各構成部材の接合部同士をろう付け接合して一体的に形成する。
この際、通常、熱交換器1はコア部4を水平にした状態でろう付け処理される。
この結果、受液器5の自重が中間部材8,9に鉛直方向に掛かるため、これら両者の相対位置ずれは特にコア部4の幅方向に大きく相対位置ずれする可能性が高い。
なお、中間部材8,9と受液器5とが相対位置ずれすると、連通孔8a(9a)と連通孔11d(11e)が位置ずれして流通媒体の圧力損失が増大してしまう。
そこで、連通孔11d(11e)の開口径を連通孔8a(9a)の開口径よりも幾分大きく設定してこれら両者の位置ずれを許容するようにしているが、連通孔11d(11e)の開口径をあまり大きく設定すると、中間部材8(9)と受液器5との接合面積を確保できず、中間部材8,9の大型化やろう付け不良を招いてしまう。
Next, the heat exchanger 1 temporarily assembled in this way is heat-treated in a heating furnace, and the joint portions of the respective constituent members are brazed and integrally formed.
At this time, the heat exchanger 1 is normally brazed in a state where the core portion 4 is horizontal.
As a result, since the weight of the liquid receiver 5 is applied to the intermediate members 8 and 9 in the vertical direction, the relative positional shift between them is particularly likely to be greatly shifted in the width direction of the core portion 4.
If the intermediate members 8 and 9 and the liquid receiver 5 are displaced relative to each other, the communication holes 8a (9a) and the communication holes 11d (11e) are displaced from each other, and the pressure loss of the flow medium increases.
Therefore, the opening diameter of the communication hole 11d (11e) is set to be slightly larger than the opening diameter of the communication hole 8a (9a) so as to allow the positional deviation between them, but the communication hole 11d (11e) If the opening diameter is set too large, the joint area between the intermediate member 8 (9) and the liquid receiver 5 cannot be secured, leading to an increase in the size of the intermediate members 8 and 9 and poor brazing.

これに対し、実施例1では、固定部11cの両側壁11a,11aが中間部材8,9の座部8c,9cの側面に当接し、さらに、加締め部11f,11fによって座部8c,9cが加締め固定されている。
これにより、ろう付け処理中に該中間部材8,9が位置ずれする虞がなく、これらを良好に位置決めした状態でろう付け接合できる。
加えて、位置決めした状態はろう付け処理後も維持されるため、接合耐久性を向上でき、ひいては熱交換器1の耐久性を向上できる。
On the other hand, in the first embodiment, both side walls 11a and 11a of the fixing portion 11c abut against the side surfaces of the seat portions 8c and 9c of the intermediate members 8 and 9, and the seat portions 8c and 9c are further fastened by the crimping portions 11f and 11f. Is fixed by crimping.
Thereby, there is no possibility that the intermediate members 8 and 9 are displaced during the brazing process, and it is possible to braze and join them in a well-positioned state.
In addition, since the positioned state is maintained even after the brazing process, the joining durability can be improved, and consequently the durability of the heat exchanger 1 can be improved.

なお、第1分割部材11の上端部と第2分割部材12のビード部12bとの間には、フラックス入りリングロー(フラックスコワードワイヤー)部材を設けて接合すると、これら両者の良好な接合を得られる。   In addition, when a flux-cored ring low (flux-coward wire) member is provided and joined between the upper end portion of the first divided member 11 and the bead portion 12b of the second divided member 12, good bonding of both of them can be achieved. can get.

次に、受液器5の本体13の上方開口端部13bから収容部材20を室P3内に挿入配置する。   Next, the accommodating member 20 is inserted and disposed in the chamber P3 from the upper opening end 13b of the main body 13 of the liquid receiver 5.

次に、本体13の上方開口端部13bに閉塞部材15を圧入固定した後、閉塞部材15の挿入部15bの外周と本体13の上方開口端部13bの内周との当接部位(図15の太線で図示、以下は閉塞部材15の接合部と称する)を高周波誘導加熱にてろう付け接合する。   Next, after the closing member 15 is press-fitted and fixed to the upper opening end 13b of the main body 13, the contact portion between the outer periphery of the insertion portion 15b of the closing member 15 and the inner periphery of the upper opening end 13b of the main body 13 (FIG. 15). Are shown in bold lines, and hereinafter referred to as a joint portion of the closing member 15).

なお、高周波誘導加熱は、公知の特開平7−9119号公報または特開平6−295782号公報等に記載の技術と同様であるため、その詳細は簡略して説明する。
即ち、高周波誘導加熱は、高周波電流の流れるワークコイルの中に置かれた導電体(通電性を持つ材料)が、電磁誘導作用によって導電体に生じる渦電流損による発熱と、ヒステリシス損によって導電体に生じる発熱(磁性材料の各分子が交流磁束によって振動、摩擦するため発生する熱量)により急速に加熱される現象を利用するものである。
The high-frequency induction heating is the same as the technique described in the publicly known Japanese Patent Application Laid-Open No. 7-9119 or Japanese Patent Application Laid-Open No. 6-295882, and the details thereof will be briefly described.
In other words, high-frequency induction heating is based on the heat generated by eddy current loss caused by electromagnetic induction in a conductor (material with conductivity) placed in a work coil through which high-frequency current flows, and hysteresis loss. The phenomenon of rapid heating by the heat generated (the amount of heat generated because each molecule of the magnetic material vibrates and rubs with an alternating magnetic flux) is utilized.

図14、15に示すように、実施例1では、閉塞部材15の外面に、ろう材(ブレージングシート)が設けられている。
また、発信器31と電気的に接続されたループ状のワークコイル32が閉塞部材15の接合部の周囲を囲むように配置されている。
なお、ワークコイル32は多重巻ではなくΩ状の1巻のタイプの場合もある。
また、発信器31はコントローラ33に電気的に接続されている。
コントローラ33には、発信器31の制御方法が書き換え可能なメモリにプログラムとして記憶されており、このプログラムを実行して発信器31に指令信号を送信することにより、接合部の加熱調整を制御するようになっている。
As shown in FIGS. 14 and 15, in Example 1, a brazing material (brazing sheet) is provided on the outer surface of the closing member 15.
A loop-shaped work coil 32 electrically connected to the transmitter 31 is arranged so as to surround the periphery of the joint portion of the closing member 15.
Note that the work coil 32 may be of a single Ω-shaped type instead of multiple windings.
The transmitter 31 is electrically connected to the controller 33.
The controller 33 stores the control method of the transmitter 31 in a rewritable memory as a program. The controller 33 executes the program and transmits a command signal to the transmitter 31 to control the heating adjustment of the joint. It is like that.

また、コントローラ33には、図16に示すような、加熱開始から時間軸に対する閉塞部材15の接合部の目標温度が予め記憶されており、この目標温度に合わせて発信器31に指令信号を送信する。
これにより、閉塞部材15の接合部の昇温を制御して安定したろう付け接合を実現できる。
Further, the controller 33 stores in advance the target temperature of the joint portion of the closing member 15 with respect to the time axis from the start of heating as shown in FIG. 16, and transmits a command signal to the transmitter 31 in accordance with this target temperature. To do.
Thereby, stable brazing joining is realizable by controlling the temperature rise of the junction part of the closure member 15. FIG.

そして、コントローラ33による指令信号によって発信器31からワークコイル32に高周波電流が流れると、ワークコイル32の内側に配置された閉塞部材15の接合部が加熱し、この結果、この接合部のろう材を溶融させて、閉塞部材15を良好にろう付け接合できる。
なお、この際、閉塞部材15の底部15aの外面と挿入部15bの外面とは緩やかな曲面で接続されているため、閉塞部材15において、接合部から比較的離れた部位のろう材の一部を毛細管現象によって、挿入部15bの外周と本体13の上方開口端部13bの内周との間、即ち、接合部に進入させて補充することができる。
When a high frequency current flows from the transmitter 31 to the work coil 32 by a command signal from the controller 33, the joint portion of the closing member 15 disposed inside the work coil 32 is heated. As a result, the brazing material of the joint portion is heated. Can be melted to satisfactorily braze the closure member 15.
At this time, since the outer surface of the bottom portion 15a of the closing member 15 and the outer surface of the insertion portion 15b are connected by a gentle curved surface, a part of the brazing material at a portion relatively distant from the joint portion in the closing member 15 is connected. Can be replenished by capillarity by entering between the outer periphery of the insertion portion 15 b and the inner periphery of the upper opening end portion 13 b of the main body 13, that is, the joint portion.

ここで、従来の発明において、閉塞部材を受液器に対して、例えば溶接で接合する場合には、受液器と熱交換器のタンクとが非常に接近しているため、溶接作業性が悪い上、溶接時の熱がタンクに悪影響を及ぼす虞があった。
また、ワークコイルによる高周波誘導加熱を用いてろう付け接合する場合には、ワークコイルと本体(正確には閉塞部材の接合部)との間に所定隙間を確保できず、ろう付け不良を招く虞がある。
なお、高周波誘導加熱において、この所定隙間は重要設定項目である。
あるいは、ワークコイルと本体との間に所定の距離を確保できた場合であっても、ワークコイルとタンクとが非常に接近してしまうため、高周波誘導加熱時の熱がタンクの接合部のろう材を溶融してしまう虞がある。
Here, in the conventional invention, when the closing member is joined to the liquid receiver, for example, by welding, since the liquid receiver and the tank of the heat exchanger are very close to each other, welding workability is improved. In addition, there was a possibility that the heat during welding had an adverse effect on the tank.
Further, when brazing and joining using high-frequency induction heating by a work coil, a predetermined gap cannot be secured between the work coil and the main body (more precisely, the joining portion of the closing member), which may lead to poor brazing. There is.
In the high frequency induction heating, the predetermined gap is an important setting item.
Alternatively, even when a predetermined distance can be secured between the work coil and the main body, the work coil and the tank are very close to each other, so the heat generated during high-frequency induction heating can be There is a risk of melting the material.

これに対し、実施例1では、前述したように、第2分割部材12の縮径部12cにより受液器5が縮径しているため、閉塞部材15の接合部付近における本体13とタンク3との間に十分な隙間を確保できる。
これにより、ワークコイル32と本体13(閉塞部材15の接合部)との間に所定隙間を確保できる。
加えて、ワークコイル32とタンク3とが過度に接近しないため、高周波誘導加熱時の熱がタンク3に悪影響を及ぼす虞がなく、タンク3を保護できる。
On the other hand, in Example 1, since the liquid receiver 5 is reduced in diameter by the reduced diameter portion 12c of the second divided member 12 as described above, the main body 13 and the tank 3 in the vicinity of the joint portion of the closing member 15 are used. A sufficient gap can be secured between the two.
Thereby, a predetermined clearance can be secured between the work coil 32 and the main body 13 (joint portion of the closing member 15).
In addition, since the work coil 32 and the tank 3 are not excessively close to each other, the heat at the time of high-frequency induction heating does not have a possibility of adversely affecting the tank 3, and the tank 3 can be protected.

また、第2分割部材12の縮径部12cが縮径していることで、本体13の熱マスを小さくでき、閉塞部材15の接合部のスムーズな昇温を実現できる。
加えて、閉塞部材15の接合部の接合面積を小さくでき、ろう材の使用量を少なくして材料コストを低く抑えることができる上、接合に掛かる時間を短縮できる。
さらに、閉塞部材15の接合部の接合面積を小さくしたことで、密閉度(耐圧性)を更に高くできる。
Moreover, since the diameter reduction part 12c of the 2nd division member 12 is diameter-reduced, the thermal mass of the main body 13 can be made small and the smooth temperature rise of the junction part of the closure member 15 is realizable.
In addition, the joining area of the joining portion of the closing member 15 can be reduced, the amount of brazing material used can be reduced, the material cost can be kept low, and the time required for joining can be shortened.
Furthermore, the sealing degree (pressure resistance) can be further increased by reducing the joining area of the joining portion of the closing member 15.

また、コントローラ33による発信器31の制御により、閉塞部材15の接合部の昇温を制御でき、安定したろう付け接合を実現できる。   Further, by controlling the transmitter 31 by the controller 33, the temperature rise of the joint portion of the closing member 15 can be controlled, and stable brazing joining can be realized.

このように、実施例1では、閉塞部材15を本体13の上方開口端部13bに良好にろう付け接合でき、シール部材と螺子溝を用いた閉塞部材の密閉構造に比べて、非常に高い耐圧性を実現できる。
なお、実施例1では、閉塞部材15を本体13の上端部にワークコイル32による高周波誘導加熱にてろう付け接合したが、溶接で固定する場合もあり得る。
この場合も同様の作用・効果を得ることができる。
Thus, in Example 1, the closing member 15 can be satisfactorily brazed to the upper opening end portion 13b of the main body 13, and the pressure resistance is very high compared to the sealing structure of the closing member using the sealing member and the screw groove. Can be realized.
In the first embodiment, the closing member 15 is brazed to the upper end portion of the main body 13 by high frequency induction heating using the work coil 32, but may be fixed by welding.
In this case, the same action and effect can be obtained.

[閉塞部材の接合部位について]
次に、図17〜24に基づいて、閉塞部材15の接合部の形態について説明する。
なお、図17〜24において、ろう材40は毛細管現象により閉塞部材15の接合部に進入して、ろう付け接合されるが、その図示・説明は省略する。
[About the joint part of the blocking member]
Next, based on FIGS. 17-24, the form of the junction part of the closure member 15 is demonstrated.
In FIGS. 17 to 24, the brazing material 40 enters the joint portion of the closing member 15 by capillary action and is brazed and joined, but illustration and description thereof are omitted.
