Description

本発明は、熱交換器に関する。   The present invention relates to a heat exchanger.

自動車に用いられる熱交換器として、空気調和装置に組み込まれるヒータコアが知られている。特許文献１には、並列に配置される複数のチューブからなるコア部と、チューブの長手方向両端にコア部を挟み込むように配置される一対のタンクとからなり、タンク内部が仕切り板により区画されているヒータコアが開示されている。上記文献に記載された熱交換器のタンクは、コア部に接続されるコアプレートと、コアプレートと組み合わされることによってタンク内空間を画成するタンクプレートとからなる、いわゆる合わせタンクである。そして、仕切り板は、仕切り板に設けた突片がコアプレート及びタンクプレートのそれぞれに設けた切り欠きに係合することによって位置決めされる。そして、コアプレート及びタンクプレートの切り欠きを貫通してタンク外部に露出している突片が、タンク成形時にプレス成形によって潰され、切り欠きと突片との隙間を塞ぐ。これにより、タンク内を流れる流体が外部に漏れることを防止している。   As a heat exchanger used in an automobile, a heater core incorporated in an air conditioner is known. Patent Document 1 includes a core portion composed of a plurality of tubes arranged in parallel and a pair of tanks disposed so as to sandwich the core portion at both ends in the longitudinal direction of the tube, and the inside of the tank is partitioned by a partition plate. A heater core is disclosed. The tank of the heat exchanger described in the above document is a so-called combined tank that includes a core plate connected to the core portion and a tank plate that defines the space in the tank by being combined with the core plate. And a partition plate is positioned by the protrusion provided in the partition plate engaging with the notch provided in each of the core plate and the tank plate. And the protrusion which penetrates the notch of a core plate and a tank plate and is exposed outside the tank is crushed by press molding at the time of tank molding, and the gap between the notch and the protrusion is closed. Thereby, the fluid flowing in the tank is prevented from leaking to the outside.

ところで、熱交換器の軽量化や材料費の低減のためには各部材の薄肉化が有効であるが、上記構成において仕切り板を薄肉化すると、プレス成形による変形部分により切り欠きと突片との隙間を塞ぐことが難しくなり、内部を流れる冷却液が外部に漏れるおそれがある。   By the way, in order to reduce the weight of the heat exchanger and reduce the material cost, it is effective to reduce the thickness of each member. It is difficult to close the gap, and the coolant flowing inside may leak to the outside.

そこで本発明では、仕切り板の薄肉化を進めた場合にも、漏れを防止し得るタンクを提供することを目的とする。   Accordingly, an object of the present invention is to provide a tank capable of preventing leakage even when the partition plate is made thinner.

本発明のある態様によれば、両端が開口し並列に配置される複数の管材を含んで構成されるコア部と、コア部に対して管材の長手方向両側から挟むように接合され、管材と連通する一対のタンクと、タンクの管材配列方向に交差する断面を閉塞する仕切り板とを備える熱交換器が提供される。熱交換器の仕切り板は、タンクの内壁面と当接する外縁部に凹部を有し、タンクは内壁面に凹部と係合する凸部を有し、凸部と凹部とは、タンクの内部に仕切り板を配置した状態で、タンクの仕切り板と当接する部位を、タンクの外側から内側に向けて塑性加工することによって形成されたものである。   According to an aspect of the present invention, a core part including a plurality of pipes that are open at both ends and arranged in parallel, and a pipe member that is bonded to the core part so as to be sandwiched from both sides in the longitudinal direction of the pipe material, There is provided a heat exchanger that includes a pair of communicating tanks and a partition plate that closes a cross section that intersects the tube arrangement direction of the tanks. The partition plate of the heat exchanger has a concave portion on the outer edge that contacts the inner wall surface of the tank, the tank has a convex portion that engages with the concave portion on the inner wall surface, and the convex portion and the concave portion are located inside the tank. In a state where the partition plate is arranged, the portion that contacts the partition plate of the tank is formed by plastic working from the outside to the inside of the tank.

上記態様によれば、仕切り板は凸部と凹部との係合によりタンクに対して位置決めされ、塑性加工により変形する部位がタンクの外部に突出していないので、軽量化のために仕切り板をさらに薄肉化した場合でも、タンクの外部に冷却液が漏れるおそれはない。   According to the above aspect, the partition plate is positioned with respect to the tank by the engagement between the convex portion and the concave portion, and the portion deformed by plastic processing does not protrude outside the tank. Even when the thickness is reduced, there is no possibility that the coolant leaks outside the tank.

The heat exchanger 1 is used, for example, as a heat exchanger for heating mounted on a vehicle, a so-called heater core, and is formed by brazing and joining each member made of an aluminum alloy. Brazing joining is performed by laminating brazing materials on the surface of at least one of the members that are in contact with each other, and placing each member in a furnace and heating it. Details of each member will be described later.

熱交換器１は、両端が開口し並列に配置される複数の管材３と、互いに隣り合う管材３の間に挟持したコルゲート型のフィン４とを含んで構成されるコア部７と、コア部７に管材３の長手方向両側から挟むように接合され、管材３と連通する一対のタンク２Ａ、２Ｂと、を備える。   The heat exchanger 1 includes a core part 7 including a plurality of pipes 3 that are open at both ends and arranged in parallel, and a corrugated fin 4 sandwiched between the pipes 3 adjacent to each other. 7, a pair of tanks 2 </ b> A and 2 </ b> B that are joined so as to be sandwiched from both longitudinal sides of the pipe material 3 and communicate with the pipe material 3.

一方のタンク２Ａには、熱交換器１に冷却液を供給する供給流路５と、熱交換器１から冷却液を排出する排出流路６と、が接続されている。また、タンク２Ａは、図１には表れていないが、タンク２Ａの管材配列方向に交差する断面を閉塞する仕切り板１２を備えている。仕切り板１２の形状や位置決めについては後述する。   One tank 2 </ b> A is connected to a supply flow path 5 for supplying a coolant to the heat exchanger 1 and a discharge flow path 6 for discharging the coolant from the heat exchanger 1. In addition, the tank 2A includes a partition plate 12 that is not shown in FIG. 1 but closes a cross section that intersects the tube arrangement direction of the tank 2A.

Here, for convenience, in the space partitioned by the partition plate 12 in the tank 2A, the side to which the supply flow path 5 is connected is referred to as the input side, and the side to which the discharge flow path 6 is connected is referred to as the output side. .

上記のように仕切り板１２を配設することで、供給流路５から供給された冷却液は、タンク２Ａの入側に接続された各管材３を介してタンク２Ｂへ流入し、タンク２Ｂ内を移動して、タンク２Ａの出側に接続された各管材３を介してタンク２Ａの出側へと戻り、排出流路６を介して排出される。そして、冷却液は、主に管材３を流れる間に管材３と熱交換することで冷却される。   By disposing the partition plate 12 as described above, the coolant supplied from the supply flow path 5 flows into the tank 2B via the pipes 3 connected to the inlet side of the tank 2A, and enters the tank 2B. , And returns to the exit side of the tank 2A via the pipes 3 connected to the exit side of the tank 2A, and is discharged via the discharge passage 6. The cooling liquid is cooled by exchanging heat with the pipe material 3 while mainly flowing through the pipe material 3.

図２は、図１のII部分、つまり、タンク２Ａの仕切り板１２を配設した部位の斜視図である。図３は、図２と同部位の分解図である。   FIG. 2 is a perspective view of a portion II in FIG. 1, that is, a portion where the partition plate 12 of the tank 2A is disposed. FIG. 3 is an exploded view of the same portion as FIG.

タンク２Ａは、コア部７に接合されるコアプレート１０と、コアプレート１０に接合されるタンクプレート１１と、コアプレート１０とタンクプレート１１とで形成されるタンク空間を分割するための仕切り板１２と、を含んで構成される。   The tank 2A includes a core plate 10 joined to the core portion 7, a tank plate 11 joined to the core plate 10, and a partition plate 12 for dividing a tank space formed by the core plate 10 and the tank plate 11. And comprising.

コアプレート１０は、管材３が挿通される開口部１０Ａの列が設けられた底部１０Ｂと、開口部１０Ａの列を開口部１０Ａの配列方向と直交する方向から挟み込むよう配置され、かつ底部１０Ｂからコア部７と反対方向に延びる一対の壁部１０Ｃと、を備える。つまり、コアプレート１０は、開口部１０Ａの配列方向に直交する断面の形状が略Ｕ字状の部材である。   The core plate 10 is disposed so as to sandwich the row of the opening 10A through which the tube material 3 is inserted and the row of the opening 10A from a direction orthogonal to the arrangement direction of the openings 10A, and from the bottom 10B. A pair of wall portions 10 </ b> C extending in the opposite direction to the core portion 7. That is, the core plate 10 is a member having a substantially U-shaped cross section perpendicular to the arrangement direction of the openings 10A.

タンクプレート１１は、コアプレート１０と共にタンク空間を形成するように、一対の壁部１０Ｃに接合される。   The tank plate 11 is joined to the pair of wall portions 10 </ b> C so as to form a tank space together with the core plate 10.

仕切り板１２は、コアプレート１０とタンクプレート１１とで形成するタンク空間を分割するために、タンク２Ａの、開口部１０Ａの配列方向と直交する断面を封鎖するよう配置されるものである。   In order to divide the tank space formed by the core plate 10 and the tank plate 11, the partition plate 12 is disposed so as to block a cross section perpendicular to the arrangement direction of the openings 10 </ b> A of the tank 2 </ b> A.

仕切り板１２の、タンクプレート１１と当接する縁部には第１突出部１２Ａが設けられており、この第１突出部１２Ａは、タンクプレート１１に設けられた係合孔１１Ａに係合する。また、仕切り板１２の、一対の壁部１０Ｃと対向する縁部には一対の第２突出部１２Ｂが設けられており、この一対の第２突出部１２Ｂは、タンクプレート１１に設けられた一対の切り欠き部１１Ｂに係合する。   A first protrusion 12 </ b> A is provided at an edge of the partition plate 12 that contacts the tank plate 11, and the first protrusion 12 </ b> A engages with an engagement hole 11 </ b> A provided in the tank plate 11. In addition, a pair of second projecting portions 12 </ b> B are provided at the edge portions of the partition plate 12 that face the pair of wall portions 10 </ b> C, and the pair of second projecting portions 12 </ b> B are provided on the tank plate 11. Is engaged with the notch 11B.

上記のタンクプレート１１及び仕切り板１２は、一対の壁部１０Ｃに設けた後述する凸部１３によって、コアプレート１０に対する位置決めがなされる。   The tank plate 11 and the partition plate 12 are positioned with respect to the core plate 10 by convex portions 13 (described later) provided on the pair of wall portions 10C.

なお、タンク２Ａ、２Ｂの両端部分は、仕切り板１２と同様の端板で閉塞してもよいし、コアプレート１０またはタンクプレート１１を、両端が閉塞された状態の桶状に成形してもよい。   Note that both end portions of the tanks 2A and 2B may be closed by end plates similar to the partition plate 12, or the core plate 10 or the tank plate 11 may be formed into a bowl shape with both ends closed. Good.

次に、タンク部２Ａの形成手順について説明する。   Next, a procedure for forming the tank portion 2A will be described.

図４Ａ、図４Ｂはいずれも、図２のＩＶ−ＩＶ断面図（パンチ１４を打ち込む部分を含む断面図）であり、図４Ａは、コアプレート１０、タンクプレート１１及び仕切り板１２を仮組みした状態を示し、図４Ｂは、塑性変形によりた凸部１３が形成された状態を示している。   4A and 4B are both cross-sectional views taken along the line IV-IV in FIG. 2 (a cross-sectional view including a portion into which the punch 14 is driven), and FIG. 4A is a temporary assembly of the core plate 10, the tank plate 11, and the partition plate 12. The state is shown, and FIG. 4B shows a state in which the convex portion 13 is formed by plastic deformation.

図４Ａに示すように、一対の壁部１０Ｃの互いに対向する面には、仕切り板１２の第２突出部１２Ｂが着座する段付き部２０が設けられている。   As shown to FIG. 4A, the step part 20 in which the 2nd protrusion part 12B of the partition plate 12 seats is provided in the mutually opposing surface of a pair of wall part 10C.

仮組み状態は、第１突出部１２Ａとタンクプレート１１の係合孔１１Ａとが係合し、かつ、一対の第２突出部１２Ｂとタンクプレート１１の切り欠き部１１Ｂとが係合した状態の仕切り板１２及びタンクプレート１１を、第２突出部１２Ｂが段付き部２０に着座するようにコアプレート１０に組み合わせた状態である。   The temporarily assembled state is a state in which the first projecting portion 12A and the engagement hole 11A of the tank plate 11 are engaged, and the pair of second projecting portions 12B and the notch portions 11B of the tank plate 11 are engaged. In this state, the partition plate 12 and the tank plate 11 are combined with the core plate 10 so that the second projecting portion 12 </ b> B is seated on the stepped portion 20.

尚、この実施形態では、仕切り板１２の第１突出部１２Ａとタンクプレート１１の係合孔１１Ａとを単に係合させているが、第１突出部１２Ａをタンクプレート１１の外側で塑性変形させて、仕切り板１２が係合孔１１Ａから抜けないように密着して仮固定させても構わない。   In this embodiment, the first protrusion 12A of the partition plate 12 and the engagement hole 11A of the tank plate 11 are simply engaged, but the first protrusion 12A is plastically deformed outside the tank plate 11. Then, the partition plate 12 may be in close contact and temporarily fixed so as not to come out of the engagement hole 11A.

仮組み状態にしたら、壁部１０Ｃの、第２突出部１２Ｂの突出方向側の外縁部と当接する部位に、タンク２Ａの外側から内側に向かってパンチ１４を打ち込む。パンチ１４は、例えば先端が球状で、直径が仕切り板１２の板厚と同等またはそれ以下のものを用いる。   Once in the temporarily assembled state, the punch 14 is driven inward from the outside to the inside of the tank 2A into the portion of the wall portion 10C that comes into contact with the outer edge portion on the protruding direction side of the second protruding portion 12B. For example, the punch 14 has a spherical tip and a diameter equal to or less than the thickness of the partition plate 12.

これにより、コアプレート１０のパンチを打ち込んだ部位は塑性変形し、タンク２Ａの内側方向に凸な凸部１３が形成され、第２突出部１２Ｂの外縁部には凸部１３と係合する凹部１５が形成される。   As a result, the punched portion of the core plate 10 is plastically deformed to form a convex portion 13 that protrudes inward of the tank 2A, and a concave portion that engages with the convex portion 13 on the outer edge of the second protruding portion 12B. 15 is formed.

上記のように凸部１３及び凹部１５を形成したら、コアプレート１０、タンクプレート１１、及び仕切り板１２をロウ付け接合する。これにより、タンク２Ａが形成される。   When the convex portion 13 and the concave portion 15 are formed as described above, the core plate 10, the tank plate 11, and the partition plate 12 are brazed and joined. Thereby, the tank 2A is formed.

図５は、図４ＢのＶ−Ｖ断面図であり、図６は、図４ＢのＶＩ−ＶＩ断面図である。   5 is a VV cross-sectional view of FIG. 4B, and FIG. 6 is a VI-VI cross-sectional view of FIG. 4B.

図５、６に示すように、パンチ１４を打ち込むことによりコアプレート１０に形成された凸部１３と仕切り板１２に形成された凹部１５とは互いに係合し、また、凸部１３はタンクプレート１１の切り欠き部１１Ｂとも係合している。   As shown in FIGS. 5 and 6, the protrusion 13 formed in the core plate 10 and the recess 15 formed in the partition plate 12 are engaged with each other by driving the punch 14, and the protrusion 13 is the tank plate. 11 is also engaged with the notch 11B.

図７は図４ＡのVII−VII断面図であり、図８は図４ＢのVIII−VIII断面図である。   7 is a sectional view taken along line VII-VII in FIG. 4A, and FIG. 8 is a sectional view taken along line VIII-VIII in FIG. 4B.

図７および図８の上下方向を、切り欠き部１１Ｂの幅方向、仕切り板１２の厚さ方向とし、パンチ１４を打ち込む前の切り欠き部１１Ｂの幅を幅Ｂ、同じく仕切り板１２の第２突出部１２Ｂの厚さを厚さＡとすると、図７および図８に示すように幅Ｂ＞厚さＡという関係が成立する。つまり、パンチ１４を打つ込む前の仮組み状態では、切り欠き部１１Ｂと仕切り板１２の第２突出部１２Ｂとの間に隙間がある。   The vertical direction of FIGS. 7 and 8 is the width direction of the notch 11B and the thickness direction of the partition plate 12, and the width of the notch 11B before the punch 14 is driven is the width B. Assuming that the thickness of the protruding portion 12B is the thickness A, the relationship of width B> thickness A is established as shown in FIGS. That is, in the temporarily assembled state before the punch 14 is driven, there is a gap between the notch portion 11B and the second protruding portion 12B of the partition plate 12.

しかし、パンチ１４が打ち込まれると、第２突出部１２Ｂは塑性変形して厚さＡが増大し、切り欠き部１１Ｂとの隙間が埋まる。つまり、コアプレート１０、タンクプレート１１及び仕切り板１２が一体化する。   However, when the punch 14 is driven, the second protrusion 12B is plastically deformed to increase the thickness A, and the gap with the notch 11B is filled. That is, the core plate 10, the tank plate 11, and the partition plate 12 are integrated.

なお、ここではタンク２Ａに仕切り板１２が１枚だけ配置される場合について説明したが、２枚以上備える場合も同様にパンチ１４を打ち込むことで仕切り板１２を固定する。また、タンク２Ａに仕切り板１２を２枚以上配置する場合にはタンク２Ｂにも仕切り板１２を配置することになるが、この場合も仕切り板１２を固定する構成は同様である。   In addition, although the case where only one partition plate 12 is disposed in the tank 2A has been described here, the partition plate 12 is fixed by driving the punch 14 in the same manner when two or more partition plates 12 are provided. Further, when two or more partition plates 12 are disposed in the tank 2A, the partition plates 12 are also disposed in the tank 2B. In this case, the configuration for fixing the partition plates 12 is the same.

次に、タンク２Ａを上記のような構成にすることによって得られる効果について説明する。   Next, effects obtained by configuring the tank 2A as described above will be described.

（１）本実施形態の熱交換器１においては、仕切り板１２はタンク２Ａの内壁面と当接する部位に凹部１５を有し、タンク２Ａは凹部１５と係合する凸部１３を有する。そして、凸部１３と凹部１５とは、タンク２Ａの内部に仕切り板１２を配置した状態で、タンク２Ａの仕切り板１２と当接する部位に、タンク２Ａの外側から内側に向けてパンチ１４を打ち込むことによって形成したものである。すなわち、仕切り板１２は凸部１３と凹部１５との係合によりタンク２Ａに対して位置決めされる。そして、パンチ１４の打ち込みによる仕切り板１２の変形部位がタンク２Ａの外部に突出していないので、仕切り板１２の薄肉化を進めた場合でも、仕切り板１２とタンク２Ａの壁面との隙間からの冷却液の漏れは生じない。   (1) In the heat exchanger 1 of this embodiment, the partition plate 12 has the recessed part 15 in the site | part which contact | abuts the inner wall surface of the tank 2A, and the tank 2A has the convex part 13 engaged with the recessed part 15. FIG. And the convex part 13 and the recessed part 15 drive the punch 14 in the part which contact | abuts the partition plate 12 of the tank 2A toward the inside from the outer side of the tank 2A in the state which has arrange | positioned the partition plate 12 inside the tank 2A. It is formed by. That is, the partition plate 12 is positioned with respect to the tank 2 </ b> A by the engagement between the convex portion 13 and the concave portion 15. And since the deformation | transformation site | part of the partition plate 12 by the driving of the punch 14 does not protrude outside the tank 2A, even when the partition plate 12 is made thinner, cooling from the gap between the partition plate 12 and the wall surface of the tank 2A is performed. Liquid leakage does not occur.

（２）本実施形態では、タンク２Ａはコアプレート１０とタンクプレート１１とを含んで構成され、タンクプレート１１は一対の切り欠き部１１Ｂを備え、仕切り板１２は切り欠き部１１Ｂに係合する。そして、仕切り板１２の、切り欠き部１１Ｂと係合する部位に凹部１５が形成される。これにより、仕切り板１２は、タンクプレート１１に対しては切り欠き部１１Ｂと係合することで位置決めされ、コアプレート１０に対しては凸部１３と凹部１５とが係合することで位置決めされる。また、パンチ１４を打ち込むことで形成された凸部１３は、切り欠き部１１Ｂにも係合することとなる。   (2) In the present embodiment, the tank 2A includes the core plate 10 and the tank plate 11, and the tank plate 11 includes a pair of notches 11B, and the partition plate 12 engages with the notches 11B. . And the recessed part 15 is formed in the site | part engaged with the notch part 11B of the partition plate 12. As shown in FIG. Thereby, the partition plate 12 is positioned by engaging the notch portion 11B with respect to the tank plate 11, and is positioned by engaging the convex portion 13 and the concave portion 15 with respect to the core plate 10. The Moreover, the convex part 13 formed by driving | punching the punch 14 will also engage with the notch part 11B.

すなわち、パンチ１４を打ち込んで凸部１３と凹部１５とを形成することにより、コアプレート１０に対する仕切り板１２の位置決めがなされ、これと同時にタンクプレート１１のコアプレートに対する位置決めもなされる。したがって、本実施形態によればタンク２Ａの組み立てに要する工程を簡略化し、コストダウンを図ることができる。   That is, by punching the punch 14 to form the convex portion 13 and the concave portion 15, the partition plate 12 is positioned with respect to the core plate 10, and at the same time, the tank plate 11 is positioned with respect to the core plate. Therefore, according to this embodiment, the process required for assembling the tank 2A can be simplified and the cost can be reduced.

また、パンチ１４が打ち込まれるのはコアプレート１１の仕切り板１２と当接する部位だけなので、パンチ１４を打ち込むことによるタンク２Ａの変形が抑制されて、安定したロウ付けを行なうことができる。   In addition, since the punch 14 is driven only in a portion that contacts the partition plate 12 of the core plate 11, deformation of the tank 2A due to the punch 14 being driven is suppressed, and stable brazing can be performed.

（３）本実施形態では、仕切り板１２は切り欠き部１１に係合する部位が壁部１０Ｃの方向に突出する第２突出部１２Ｂとなっており、コアプレート１０には第２突出部１２Ｂが着座する段付き部２０が設けられている。これにより、パンチ１４を打ち込む前の仮組み状態のタンク２Ａにおいて、仕切り板１２及びタンクプレート１１がコアプレート１０に対して開口部１０Ａの配列方向を軸として回転してしまうことを防止し、精度よくタンク２Ａを組み立てることができる。   (3) In this embodiment, the part of the partition plate 12 that engages with the notch 11 is the second protrusion 12B that protrudes in the direction of the wall 10C, and the core plate 10 has the second protrusion 12B. A stepped portion 20 is provided on which is seated. This prevents the partition plate 12 and the tank plate 11 from rotating about the arrangement direction of the opening 10A with respect to the core plate 10 in the temporarily assembled tank 2A before the punch 14 is driven. The tank 2A can be assembled well.

（４）本実施形態では、タンクプレート１１は、一対の切り欠き部１１Ｂを結ぶ線上に係合孔（貫通孔）１１Ａを有し、仕切り板１２は、係合孔１１Ａに係合する第１突出部（係合部）１２Ａを有する。これにより、仕切り板１２のタンクプレート１１に対する位置決めがより確実になされる。   (4) In the present embodiment, the tank plate 11 has an engagement hole (through hole) 11A on a line connecting the pair of notches 11B, and the partition plate 12 is engaged with the engagement hole 11A. It has a protruding portion (engaging portion) 12A. Thereby, positioning with respect to the tank plate 11 of the partition plate 12 is made more reliably.

なお、本発明は上記の実施の形態に限定されるわけではなく、特許請求の範囲に記載の技術的思想の範囲内で様々な変更を成し得ることは言うまでもない。   The present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made within the scope of the technical idea described in the claims.
