【産業上の利用分野】[Industrial applications]

この考案は、カーエアコン用凝縮器やラジエター等に用いられる熱交換器に関 する。 The present invention relates to a heat exchanger used for a car air conditioner condenser, a radiator, or the like.

【0002】[0002]

【従来の技術】[Prior Art]

例えばカーエアコン用凝縮器に用いられる熱交換器としては、従来より、ハー モニカチューブと称されるような多孔押出偏平チューブを蛇行状に曲げ、その平 行部間にフィンを配置してコアを構成したいわゆるサーペンタイン型熱交換器が 用いられていた。ところがかかるサーペンタイン型熱交換器では、熱交換媒体通 路が1本の偏平押出チューブにより形成されているため通路面積を大きく確保で きないこと、押出チューブを蛇行状に曲成してなるものであるから、曲げ部の曲 率半径を一定以上小さくできないためチューブピッチを小さくできず、このため チューブの平行部間に介在されるフィン数が少ないものとなってフィン効率が悪 いこと、等の理由から熱交換効率の向上に限界があった。 For example, as a heat exchanger used in a car air-conditioning condenser, conventionally, a perforated extruded flat tube called a harmonica tube is bent in a meandering shape, and fins are arranged between the flattened portions to form a core. The configured so-called serpentine type heat exchanger was used. However, in such a serpentine type heat exchanger, since the heat exchange medium passage is formed by one flat extruded tube, a large passage area cannot be secured, and the extruded tube is bent in a meandering shape. Therefore, it is not possible to reduce the tube pitch because the radius of curvature of the bent portion cannot be reduced more than a certain amount, so that the number of fins interposed between the parallel portions of the tube is small and the fin efficiency is poor. For some reason, there was a limit to the improvement of heat exchange efficiency.

【0003】 そこでサーペンタイン型に代わる熱交換器として、偏平チューブとフィンとを 交互配置に積層して、チューブの両端を1対の中空ヘッダーに連結した熱交換器 が提案されている。この熱交換器によれば、チューブピッチを自由に選択できる ので、冷媒通路断面積を大きく確保でき、また各チューブ間に介装されるフィン の本数も増加でき小型で熱交換効率に優れたものとなすことができる。Therefore, as a heat exchanger replacing the serpentine type, there has been proposed a heat exchanger in which flat tubes and fins are alternately stacked and both ends of the tubes are connected to a pair of hollow headers. According to this heat exchanger, since the tube pitch can be freely selected, a large cross-sectional area of the refrigerant passage can be secured, and the number of fins interposed between the tubes can be increased, which is small and has excellent heat exchange efficiency. You can

【0004】 ところで、かかる形式の熱交換器において、サーペンタイン型のものと同様に 熱交換媒体を蛇行状に流通させるために、仕切板を設けて一方または両方のヘッ ダー内部を複数の仕切室に分割し、もってチューブによって構成される熱交換媒 体通路を蛇行通路に形成せしめたものとなされる場合がある。By the way, in this type of heat exchanger, a partition plate is provided in order to distribute the heat exchange medium in a meandering manner as in the serpentine type heat exchanger, and one or both of the headers are divided into a plurality of partition chambers. In some cases, the heat exchange medium passage formed by dividing the tube into tubes is formed in a meandering passage.

【0005】 従来、このような仕切板の取付け構造として、ヘッダーを複数本の短尺筒状の ヘッダー単位により構成し、これらのヘッダー単位を中間に仕切板を介在せしめ て長さ方向に組み合せ、ろう接固定した構造とか、あるいは、単一の筒状ヘッダ ーの周壁に周方向にスリット状の切込み部を形成し、これに仕切板を挿入してろ う付け固定した構造(例えば特開昭62−131195号公報)等が採用されて いた。Conventionally, as such a partition plate mounting structure, a header is composed of a plurality of short tubular header units, and these header units are combined in the lengthwise direction with a partition plate interposed in between. A structure in which they are fixed in contact with each other, or a structure in which a slit-like cut portion is formed in the circumferential direction of the peripheral wall of a single cylindrical header and a partition plate is inserted into this, and fixed by brazing (for example, JP-A-62- No. 131195) was adopted.

【0006】[0006]

【考案が解決しようとする問題点】[Problems to be solved by the device]

しかしながら上記の前者のような構造では、部品点数が多くなってコストが上 昇したり、ろう付に際してヘッダー単位と仕切板とが位置ずれする危険性がある ため、ろう付作業が面倒で生産性が悪いというような欠点を有するものであった 。 However, in the former structure described above, the number of parts increases and the cost rises, and there is a risk that the header unit and the partition plate will be misaligned during brazing, which makes the brazing work cumbersome and increases productivity. It had the drawback of being bad.

【0007】 また、上記後者の構造においては、仕切板をスリット状切込み部に挿入して仮 組セットしたのち、これをろう付け固定するまでの取扱い過程の中で、上記仕切 板が往々にして切込み部から抜け落ちたり、あるいは位置ずれを起こして正規取 付状態が実現されないことが多く、仕切板の取付け個数が多くなればなるほど、 製造した熱交換器の不良品発生率が高くなるというような問題点があった。Further, in the latter structure, the partition plate is often inserted into the slit-shaped cut portion, temporarily set, and then brazed and fixed. In many cases, the normal mounting state cannot be realized due to slipping out of the notch or misalignment, and the higher the number of partition plates installed, the higher the defective product rate of manufactured heat exchangers. There was a problem.

【0008】 この考案は、上記のような欠点を派生することのない仕切板の取付け構造を採 用した熱交換器を提供しようというものである。The present invention is intended to provide a heat exchanger adopting a partition plate mounting structure that does not cause the above-mentioned drawbacks.

【問題点を解決するための手段】[Means for solving problems]

而してこの考案は、複数のチューブ(1)とコルゲートフィン(2)とが交互 配置に積層されるとともに、各チューブの両端が1対の中空ヘッダー(3)(4 )に連結され、かつチューブ(1)によって構成される流通路を熱交換媒体が蛇 行状に流通するように、少なくとも一方のヘッダー内部を仕切る仕切板(10)が 設けられた熱交換器であって、前記ヘッダー(3)(4)に周方向のスリット状 の切込み部(11)が形成される一方、前記仕切板(10)は、ヘッダーの内周面に 適合してヘッダー内を遮断する遮蔽部(10a )と、該遮蔽部(10a )の周縁の一 部から外方にのび、前記ヘッダーのスリット状切込み部(11)内に位置して該切 込み部を埋める取付用凸縁部(10b )とを有し、かつ少なくとも前記取付用凸縁 部(10b )の片面に抜止め用の凹凸粗面部(10c )が形成され、前記仕切板(10 )が前記切込み部(11)からヘッダー内に強制嵌入されることにより、前記凹凸 粗面部(10c )を前記切込み部(11)の内面に摩擦圧接せしめた状態でヘッダー に接合一体化されてなることを特徴とする熱交換器を要旨とするものである。 Thus, according to this invention, a plurality of tubes (1) and corrugated fins (2) are laminated in an alternating arrangement, and both ends of each tube are connected to a pair of hollow headers (3) (4), and A heat exchanger provided with a partition plate (10) partitioning at least one of the headers so that the heat exchange medium flows in a meandering manner in a flow passage formed by the tube (1), the header (3) ) (4) is formed with a circumferential slit-like cut portion (11), while the partition plate (10) has a shield portion (10a) that fits the inner peripheral surface of the header and shields the inside of the header. A mounting projection edge portion (10b) extending outward from a part of the peripheral edge of the shielding portion (10a) and located inside the slit-like cut portion (11) of the header to fill the cut portion. And at least one side of the mounting convex edge (10b) does not come out. A rough surface portion (10c) for use in forming is formed, and the partition plate (10) is forcibly fitted into the header from the cut portion (11), so that the rough surface portion (10c) is cut into the cut portion (11). The gist of the present invention is a heat exchanger characterized by being integrally joined to a header while being frictionally pressure-welded to the inner surface of the heat exchanger.

【実施例】【Example】

次にこの考案の構成を、カーエアコン用のアルミニウムないしその合金製凝縮 器に適用した実施例に基いて説明する。 Next, the structure of the present invention will be described based on an embodiment applied to a condenser made of aluminum or its alloy for car air conditioners.

【0011】 第1図〜第5図において、(1)は水平状態で上下方向に配置された複数のチ ューブ、(2)はその隣接するチューブ(1)(1)間に介在されたコルゲート フィンである。チューブ(1)はアルミニウム材による偏平状の押出形材をもっ て構成されたものである。このチューブ(1)はいわゆるハモニカチューブと称 されるような多孔型のものを用いても良い。また押出型材によらず電縫管を用い ても良い。コルゲートフィン(2)はチューブ(1)とほぼ同じ幅を有し、ろう 付によりチューブに接合されている。コルゲートフィン(2)もアルミニウム製 であり、望ましくはルーバーを切り起したものを用いるのが良い。In FIGS. 1 to 5, (1) is a plurality of tubes arranged vertically in a horizontal state, and (2) is a corrugate interposed between adjacent tubes (1) and (1). It is a fin. The tube (1) is made of a flat extruded profile made of aluminum. The tube (1) may be of a so-called harmonica tube of a porous type. Further, an electric resistance welded tube may be used instead of the extruded mold material. The corrugated fin (2) has almost the same width as the tube (1) and is joined to the tube by brazing. The corrugated fin (2) is also made of aluminum, and it is preferable to use a louver cut and raised.

【0012】 (3)(4)は左右のヘッダーである。これらのヘッダー(3)(4)は、心 材の内外両面にろう材層が被覆形成された各1本の断面円形のアルミニウム製電 縫管をもって形成されたものである。なお電縫管によらず押出形材を用いても良 い。各ヘッダーには長さ方向に沿って間隔的にチューブ挿入孔(5)が穿設され るとともに、該孔に各チューブ(1)の両端が挿入され、かつろう付により強固 に接合連結されている。さらに左ヘッダー(3)の上端には冷媒入口管(6)が 、同下端には冷媒出口管(7)が連結されている。また右ヘッダー(4)の上端 及び下端には蓋片(12)(13)がそれぞれ取着されている。さらに左ヘッダー( 3)には中央部より上側と下側の位置に各1個合計2個の仕切板(10)(10)が 設けられ、ヘッダー内が3室に仕切られる一方、右ヘッダー(4)にもほぼ中央 部に仕切板(10)が設けられ、ヘッダー内が2室に仕切られている。かかる仕切 板(10)の設置により、冷媒入口管(6)から左ヘッダー(3)に流入した冷媒 はチューブ群によって構成される全冷媒通路をめぐって蛇行状に流通し、冷媒出 口管(7)から流出するものとなされている。なお、第2図に示す(8)(9) は最外側のコルゲートフィン(2)の外側に配置された上下のサイドプレートで ある。(3) and (4) are left and right headers. These headers (3) and (4) are each formed of an aluminum electric resistance welded pipe having a circular cross section, in which a brazing material layer is formed on both inner and outer surfaces of the core material. An extruded shape may be used instead of the electric resistance welded pipe. Tube insertion holes (5) are formed in each header at intervals along the length direction, and both ends of each tube (1) are inserted into the holes and firmly joined and connected by brazing. There is. Further, a refrigerant inlet pipe (6) is connected to the upper end of the left header (3), and a refrigerant outlet pipe (7) is connected to the lower end thereof. Lid pieces (12) and (13) are attached to the upper and lower ends of the right header (4), respectively. Further, the left header (3) is provided with two partition plates (10) and (10), one above and one below the center, and the inside of the header is divided into three chambers while the right header ( Also in 4), a partition plate (10) is provided almost in the center, and the inside of the header is divided into two chambers. By installing the partition plate (10), the refrigerant flowing from the refrigerant inlet pipe (6) into the left header (3) flows in a meandering manner over all the refrigerant passages constituted by the tube group, and the refrigerant outlet pipe (7). It is supposed to flow out from. In addition, (8) and (9) shown in FIG. 2 are upper and lower side plates arranged outside the outermost corrugated fin (2).

【0013】 ところで、前記仕切板(10)のヘッダー(3)(4)への取付けは次のように して行われている。即ち、第1図に示すように、ヘッダー(3)(4)には仕切 板(10)の取着予定位置に、周方向にそのほぼ半周にわたって仕切板(10)の厚 さとほぼ等しい幅のスリット状の切込み部(11)が形成されている。一方、仕切 板(10)はヘッダー(3)(4)の内径に等しい外径を有し、ヘッダー内周面に 適合して該ヘッダー内を横断状に遮断する遮蔽部(10a )と、該遮蔽部(10a ) の約半周に亘る領域において、その周縁から外方に張り出し状にのび、前記ヘッ ダー(3)(4)のスリット状切込み部(11)内に位置してこれを埋める取付用 凸縁部(10b )とを有するものに形成されている。By the way, the partition plate (10) is attached to the headers (3) and (4) as follows. That is, as shown in FIG. 1, the headers (3) and (4) have a width approximately equal to the thickness of the partition plate (10) at a position where the partition plate (10) is to be attached, over the half direction in the circumferential direction. A slit-shaped notch (11) is formed. On the other hand, the partition plate (10) has an outer diameter equal to the inner diameter of the headers (3) and (4), and is fitted with an inner peripheral surface of the header to shield the inside of the header in a transverse manner, and An attachment that extends outward from the peripheral edge of the shielding portion (10a) in a region extending over about half the circumference and is located inside the slit-shaped notch (11) of the header (3) (4) and fills it. And a convex edge portion (10b).

【0014】 また、仕切板(10)の表面には、その全面に亘って、抜止め用としての微細な 凹凸からなる凹凸粗面部(10c )が形成されている。この凹凸粗面部(10c )の 形成には、サンドブラスト加工、ローレット加工、ブラッシング加工、あるいは プレス加工等が用いられる。このような凹凸粗面部(10c )を備えた仕切板(10 )は、第1図の切込み部(11)に圧入されることにより、前記微細な凹凸で切込 み部(11)の内面上部に摩擦圧接して係合し、抜止め作用を果すものである。従 って、該凹凸粗面部(10c )は仕切板(10)の少なくとも取付用凸縁部(10b ) の片面に形成されれば足るが、実施例に示すように全面に形成する方が製造上有 利である。Further, a rough surface portion (10c) is formed on the entire surface of the partition plate (10), which is made of fine unevenness for preventing slippage. Sand blasting, knurling, brushing, pressing, or the like is used for forming the roughened surface portion (10c). The partition plate (10) provided with such a rough surface portion (10c) is press-fitted into the cut portion (11) of FIG. 1 so that the inner surface of the cut portion (11) has the fine unevenness. It is frictionally pressure-contacted with and is engaged with, and has a retaining effect. Therefore, it is sufficient that the rough surface portion (10c) is formed on at least one side of the mounting convex edge portion (10b) of the partition plate (10), but it is better to form it on the entire surface as shown in the embodiment. It is profitable.

【0015】 ところで、仕切板(10)は、上述のように、切込み部(11)に強制嵌合される が、この嵌合状態において凹凸粗面部(10c )が切込み部(11)の上面に摩擦圧 接されることにより、これが滑り止め機能を果す。従って、仕切板(10)はこの 状態でヘッダー(3)(4)にろう接固定される際、ろう接中においても凹凸粗 面部(10c )により仕切板(10)の抜け出し、位置ずれが防止され、適正に位置 決めされることにより、ろう接後において仕切板(10)とヘッダー(3)(4) とが隙間なく接合一体化されるとともに、ヘッダー外周面と仕切板(10)の取付 用凸縁部(10b )の外周面とが合致して、凹凸のない曲面状態を呈し外観体裁が 損われることもない。By the way, the partition plate (10) is forcibly fitted to the cut portion (11) as described above. In this fitted state, the uneven rough surface portion (10c) is on the upper surface of the cut portion (11). This exerts a non-slip function when frictionally pressed. Therefore, when the partition plate (10) is brazed and fixed to the headers (3) and (4) in this state, the uneven surface (10c) prevents the partition plate (10) from slipping out and shifting even during brazing. After brazing, the partition plate (10) and the headers (3) and (4) are joined and integrated without any gaps by proper positioning, and the header outer peripheral surface and the partition plate (10) are attached. The outer peripheral surface of the projecting edge portion (10b) is matched to form a curved surface with no unevenness and the appearance is not damaged.

【0016】 なお上記実施例では、ヘッダー(3)(4)は断面円形のものを使用したが、 断面円形でなくとも良い。In the above embodiment, the headers (3) and (4) have a circular cross section, but they do not have to have a circular cross section.

【考案の効果】[Effect of the device]

以上説明したようにこの考案に係る熱交換器は、熱交換媒体を蛇行状に流通さ せるためにヘッダー内部を仕切る仕切板の取付け構造として、ヘッダーに周方向 の切込み部を形成するとともに、仕切板に切込み部の内面に摩擦圧接する抜止め 用の凹凸粗面部を設け、仕切板を切込み部からヘッダー内に強制挿入しかつ前記 凹凸粗面部を切込み部の内面に圧接させた状態でヘッダーに接合一体化した構造 を採用したものである。従って、ヘッダーを一体物で製作することができ、従来 のように短尺のヘッダー単位を中間に仕切板を介在せしめて接合する場合に較べ て部品点数を減少しうる。しかも、仕切板の抜止め用手段が仕切板の板面に形成 された凹凸粗面として形成されたものであるから、それ自体の加工が容易であり 、かつ仕切板の嵌め込みを強制操作で行うことによって容易に行うことができる ばかりか、嵌め込み後は仕切板が徒らに抜けたり、位置ずれを起こしたりするこ とがなく、嵌め込み後ろう付け完了までの過程を通じてその位置を正しく規制し うる。従って、前記部品点数の減少とも相俟って組立接合作業を簡素化しえて生 産性を向上でき、かつ仕切板の取付不良に基づく不良製品の発生を確実に防止し て製品の製造歩留りを向上しうる。 As described above, the heat exchanger according to the present invention has a partition plate mounting structure for partitioning the inside of the header to allow the heat exchange medium to flow in a meandering manner. The plate is provided with a concave and convex rough surface part for frictional pressure contact with the inner surface of the cut part, the partition plate is forcibly inserted into the header from the cut part, and the rough surface part is pressed against the inner surface of the cut part and attached to the header. This is a structure that is joined and integrated. Therefore, the header can be manufactured integrally, and the number of parts can be reduced as compared with the conventional case where a short header unit is joined in the middle with a partition plate interposed therebetween. Moreover, since the partition plate retaining means is formed as an uneven rough surface formed on the plate surface of the partition plate, it is easy to process itself and the partition plate is forcibly fitted. Not only can this be done easily, but also after the fitting, the partition plate will not be pulled out and the position will not be displaced, and the position can be properly regulated during the process after the fitting until the brazing is completed. .. Therefore, combined with the decrease in the number of parts, the assembly and joining work can be simplified to improve the productivity, and the defective product due to the improper mounting of the partition plate can be reliably prevented from occurring, thereby improving the manufacturing yield of the product. You can.
