次に、作用を説明する。
このように構成された熱交換器を製造するには、先ず、チューブ4、フィン5、レインフォース6,7を積層した後、これらの長手方向両端部にチューブプレート8を組み付けてコア部3を仮組みする。
次に、図3、7に示すように、コア部3の左右両側において、チューブプレート8とタンクプレート10を仕切り板9を介在させた状態で最中状に重ね合わせる。
この際、チューブプレート8の対向する側壁8b,8bの先端部とタンクプレート10の対向する側壁10b,10bの先端部が当接した状態となる。
また、仕切り板9のコ字状断面の対向する側壁9b,9bは複数の突起部11によって位置決めされた状態で側壁8b,8bと側壁10b,10bの内側に当接した状態となる。
Next, the operation will be described.
In order to manufacture the heat exchanger configured as described above, first, the tube 4, the fin 5, and the reinforcement 6 and 7 are laminated, and then the tube plate 8 is assembled to both ends in the longitudinal direction to attach the core portion 3. Temporarily assemble.
Next, as shown in FIGS. 3 and 7, the tube plate 8 and the tank plate 10 are overlapped in the middle with the partition plate 9 interposed between the left and right sides of the core portion 3.
At this time, the end portions of the opposite side walls 8b, 8b of the tube plate 8 and the end portions of the opposite side walls 10b, 10b of the tank plate 10 are in contact with each other.
Further, the opposing side walls 9b, 9b of the U-shaped cross section of the partition plate 9 are in contact with the side walls 8b, 8b and the side walls 10b, 10b while being positioned by the plurality of protrusions 11.

次に、図8、9に示すように、コア部3の左右両側において、チューブプレート8とタンクプレート10の長手方向両端部にそれぞれ対応するパッチT1,T2を装着することによりタンク1,2を形成する。
この際、タンク1においてパッチT1,T2の挿入部12が仕切り板9に当接することにより、その内部が仕切り板9によって第1タンク室R1と第2タンク室R2に区画され、一方、タンク2もタンク1と同様にその内部が仕切り板9によって第1タンク室R3と第2タンク室R4に区画される。
Next, as shown in FIGS. 8 and 9, the tanks 1 and 2 are mounted on the left and right sides of the core 3 by attaching patches T1 and T2 respectively corresponding to the longitudinal ends of the tube plate 8 and the tank plate 10. Form.
At this time, when the insertion portion 12 of the patches T1 and T2 contacts the partition plate 9 in the tank 1, the inside thereof is partitioned into the first tank chamber R1 and the second tank chamber R2 by the partition plate 9, while the tank 2 Similarly to the tank 1, the inside of the tank 1 is divided into a first tank chamber R3 and a second tank chamber R4 by a partition plate 9.

次に、タンク1のタンクプレート10の連通孔10aにコネクタP1の接続孔13aを連通させた状態として該コネクタP1を図外の治具で仮固定し、一方、タンク2のタンクプレート10にもタンク1と同様にコネクタP2を図外の治具で仮固定する。   Next, the connection hole 13a of the connector P1 is made to communicate with the communication hole 10a of the tank plate 10 of the tank 1, and the connector P1 is temporarily fixed with a jig (not shown). Similar to the tank 1, the connector P2 is temporarily fixed with a jig not shown.

このように仮組みされた熱交換器は、図外の加熱炉に搬送されて熱処理されることにより、各構成部材の当接部がろう付け固定されて一体的に形成される。   The heat exchanger temporarily assembled as described above is transported to a heating furnace (not shown) and subjected to heat treatment, whereby the contact portions of the respective constituent members are brazed and fixed to be integrally formed.

そして、車両に搭載された熱交換器の両コネクタP1,P2はそれぞれ図示を省略する車両側接続管に接続される他、図外のコンプレッサ側からコネクタP1の接続孔13a及びタンクプレート10の連通孔10aを介してタンク1の第1タンク室R1に流入した約70℃前後の流通媒体は、タンク1の仕切り板9の孔9aを介して第2タンク室R2に流入する。   The connectors P1 and P2 of the heat exchanger mounted on the vehicle are connected to a vehicle-side connection pipe (not shown), and the communication between the connection hole 13a of the connector P1 and the tank plate 10 from the compressor side (not shown). The circulation medium at about 70 ° C. flowing into the first tank chamber R1 of the tank 1 through the hole 10a flows into the second tank chamber R2 through the hole 9a of the partition plate 9 of the tank 1.

次に、第2タンク室R2の流通媒体は、各チューブ4を流通してタンク2の第1タンク室R3に流入する間にコア部3を通過する車両走行風またはファンによる強制風とフィン5を介して熱交換されることにより、約45℃前後まで冷却された後、タンク2の第1タンク室R3に流入する。   Next, the flow medium in the second tank chamber R2 flows through each tube 4 and flows into the first tank chamber R3 of the tank 2 while passing through the core section 3 or the forced wind by the fan and the fins 5. After being cooled to about 45 ° C. by heat exchange via the, it flows into the first tank chamber R 3 of the tank 2.

次に、タンク2の第1タンク室R3内の流通媒体は、タンク2の仕切り板9の孔9aを介して第2タンク室R4に流入した後、コネクタP2の接続孔13aから図外のエバポレータ側へ排出され、コンデンサとして機能する。   Next, the flow medium in the first tank chamber R3 of the tank 2 flows into the second tank chamber R4 through the hole 9a of the partition plate 9 of the tank 2, and then the evaporator (not shown) from the connection hole 13a of the connector P2. It is discharged to the side and functions as a capacitor.

この際、図10に示すように、タンク1の内部では、タンク1の仕切り板9の孔9aとチューブ4を対向配置しているため、第1タンク室R1の流通媒体が仕切り板9の各孔9aを介して第2タンク室R2へ均一に流入し、これによって、第2タンク室R2の流通媒体を各チューブの端部4aへ均一に整流化させた状態で流通させることができ、熱交換器の冷却性能の向上を図ることができる。   At this time, as shown in FIG. 10, inside the tank 1, the holes 9 a of the partition plate 9 of the tank 1 and the tube 4 are disposed so as to face each other. Evenly flows into the second tank chamber R2 through the holes 9a, whereby the flow medium in the second tank chamber R2 can be circulated in a uniformly rectified state to the end portions 4a of each tube, The cooling performance of the exchanger can be improved.

一方、図11に示すように、タンク2の内部では、第1タンク室R3の流通媒体が仕切り板9の各孔9aを介して第2タンク室R4へ均一に流入するため、隣り合うチューブ4から排出される流通媒体の影響を受けることなく、第1タンク室R3の流通媒体を第2タンク室R4へ均一に整流化させて流入させることができる。   On the other hand, as shown in FIG. 11, in the tank 2, the flow medium in the first tank chamber R <b> 3 flows uniformly into the second tank chamber R <b> 4 through the holes 9 a of the partition plate 9, so that the adjacent tubes 4 The flow medium in the first tank chamber R3 can be uniformly rectified and flowed into the second tank chamber R4 without being affected by the flow medium discharged from the tank.

ここで、下記のように条件の異なる熱交換器を複数用意して放熱試験を行った結果を図12に示す。
放熱試験に用いた熱交換器は、本実施例1のように一対のタンク1,2をコア部3の左右に配置した所謂クロスフロー型の熱交換器において、コア部3のコアサイズのアスペクト比(横/縦)を1.5にしたタイプXと、図13に示すように、一対のタンク1,2をコア部3の上下に配置した所謂ダウンフロー型の熱交換器において、コア部3のコアサイズのアスペクト比(横/縦)を0.7にしたタイプYと、アスペクト比を2.1にしたタイプZを用いた。
なお、チューブ4の開口断面積は約13mmであり直径4mmの孔9aの開口断面積と等しい。
Here, the result of having prepared a plurality of heat exchangers with different conditions as described below and conducting a heat dissipation test is shown in FIG.
The heat exchanger used in the heat dissipation test is a so-called cross-flow type heat exchanger in which a pair of tanks 1 and 2 are arranged on the left and right sides of the core part 3 as in the first embodiment. In the so-called downflow type heat exchanger in which the ratio (horizontal / vertical) is 1.5 and the pair of tanks 1 and 2 are arranged above and below the core 3 as shown in FIG. A type Y having an aspect ratio (horizontal / vertical) of 0.7 with a core size of 3 and a type Z having an aspect ratio of 2.1 were used.
The opening cross-sectional area of the tube 4 is equal to the cross-sectional area of the opening of the hole 9a of and 4mm diameter about 13 mm 2.

図12に示すように、本実施例1のようにクロスフロー型の熱交換器(タイプX)は、孔9aの開口断面積をチューブ4の開口断面積の1.5倍にすることによって、チューブ4に対する孔9aの位置と大きさを最適化でき、タンク1,2に仕切り板9を設けない場合に比べて最大で約5.5%の放熱性能を向上することができた。   As shown in FIG. 12, the cross flow type heat exchanger (type X) as in the first embodiment is configured such that the opening sectional area of the hole 9a is 1.5 times the opening sectional area of the tube 4, The position and size of the hole 9a with respect to the tube 4 can be optimized, and the heat dissipation performance of about 5.5% at maximum can be improved as compared with the case where the partition plates 9 are not provided in the tanks 1 and 2.

また、ダウンフロー型の熱交換器(タイプY、Z)は、孔9aの開口断面積とチューブ4の開口断面積を等しくすることによって、チューブ4に対する孔9aの位置と大きさを最適化でき、タンク1,2に仕切り板9を設けない場合に比べて最大で約1.4%の放熱性能を向上することができた。   Further, the downflow type heat exchanger (type Y, Z) can optimize the position and size of the hole 9a with respect to the tube 4 by making the opening cross-sectional area of the hole 9a and the opening cross-sectional area of the tube 4 equal. Compared with the case where the partition plates 9 are not provided in the tanks 1 and 2, the heat radiation performance can be improved by about 1.4% at maximum.

また、タイプX〜Zの熱交換器において、孔9aの数をチューブ4の本数より増減した場合や、孔9aとチューブの端部4aを対向配置ではなくオフセット配置した場合には、いずれも放熱性能が低下してしまい、実際上の使用は困難であった。   In addition, in the type X to Z heat exchanger, when the number of holes 9a is increased or decreased from the number of tubes 4, or when the holes 9a and the end portions 4a of the tubes are arranged offset rather than facing each other, heat is dissipated. The performance deteriorated, and practical use was difficult.

Next, the effect will be described.
As described above, in the tank structure of the heat exchanger according to the first embodiment, the pair of tanks 1 and 2 disposed at a predetermined interval and the pair of tanks 1 and 2 are inserted. A core portion 3 composed of a plurality of tubes 4 fixed in a state and fins 5 arranged between adjacent tubes 4, and the insides of both tanks 1, 2 have a plurality of holes 9 a. In the tank structure of the heat exchanger partitioned by the partition plate 9, since the end 4a and the hole 9a of the tube are arranged to face each other, the hole for the tube 4 is not caused without deteriorating the performance of the heat exchanger or increasing the labor for manufacturing. The position of 9a can be optimized.

また、一対のタンク1,2をコア部3の左右に配置し、孔9aの開口断面積をチューブ4の開口断面積の約1.5倍としたため、一対のタンク1,2をコア部3の左右に配置した熱交換器のチューブ4に対する孔9aの大きさを最適化できる。   Also, since the pair of tanks 1 and 2 are arranged on the left and right of the core portion 3 and the opening cross-sectional area of the hole 9a is about 1.5 times the opening cross-sectional area of the tube 4, the pair of tanks 1 and 2 are placed in the core portion 3. It is possible to optimize the size of the hole 9a with respect to the tube 4 of the heat exchanger arranged on the left and right of the.

また、一対のタンク1,2をコア部3の上下に配置し、孔9aの開口断面積とチューブ4の開口断面積を略等しくしたため、一対のタンク1,2をコア部3の上下に配置した熱交換器のチューブ4に対する孔9aの大きさを最適化できる。   In addition, the pair of tanks 1 and 2 are arranged above and below the core portion 3 so that the opening cross-sectional area of the hole 9a and the opening cross-sectional area of the tube 4 are substantially equal. The size of the hole 9a for the tube 4 of the heat exchanger can be optimized.

以上、本実施例を説明してきたが、本発明は上述の実施例に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等があっても、本発明に含まれる。
例えば、本実施例1ではタンク1,2の両方に仕切り板9を設けたが、一方側にのみ設ける場合も当然考えられる。
また、熱交換器はコンデンサに限らず、ラジエータ、オイルクーラ、インタークーラ等の一般的な熱交換器に適用しても良く、その際に行われる詳細な部位の形状変更及び材質変更等は本発明の範疇となる。
Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and design changes and the like within the scope not departing from the gist of the present invention are included in the present invention.
For example, in the first embodiment, the partition plates 9 are provided in both the tanks 1 and 2, but it is naturally conceivable that they are provided only on one side.
Moreover, the heat exchanger is not limited to the condenser, and may be applied to a general heat exchanger such as a radiator, an oil cooler, an intercooler, etc. It becomes the category of invention.
