コア部２は、交互に配置された複数のチューブ５とアウターフィン６で構成され、図４に示すように、各チューブ５は最中状に重ねられる皿状の一対のシェル7,8と、この一対のシェル7,8の間に介装されるインナーフィン９で構成されている。
両シェル7,8のうち、シェル７の長手方向両端部には上方に開口する環状突起部７ａが形成され、シェル８の長手方向両端部には下方に突出する円筒状の環状突起部８ａがそれぞれ形成されている。Thecore portion 2 is composed of a plurality of alternately arrangedtubes 5 andouter fins 6, and as shown in FIG. 4, eachtube 5 has a pair of dish-like shells 7 and 8 that are stacked in the middle, Theinner fin 9 is interposed between the pair ofshells 7 and 8.

また、図６に示すように、シェル7,8の環状突起部7a,8aに近接した位置には内側へ半円球状に窪んだエンボス部１０が前後方向に離間して形成されると共に、これら両シェル7,8が重ねられた際にインナーフィン９が各エンボス部１０により押圧された状態で位置決めされるようになっている。
さらに、図４に示すように、チューブ５におけるシェル７の環状突起部７ａの外径Ｗ１は、シェル８の環状突起部８ａの内径Ｗ２よりも小さく形成されており、これによって、図７に示すように、波状のアウターフィン６を介在させた状態で隣り合うチューブ５の環状突起部８ａと環状突起部７ａを嵌合させて複数積層することによりコア部２が形成されている。Theinner fin 9 employs so-called offset fins in which a plurality ofcolumn portions 9a as shown in FIG. 5 are arranged in parallel with the longitudinal direction of thetube 5, andshells 7 and 8 as shown in FIG. An opening 9b is formed coaxially with each of theannular projections 7a, 8a. Theinner fins 9 are not limited to offset fins, and may be wavy fins.
Further, as shown in FIG. 6, embossedportions 10 that are recessed in a semi-spherical shape inwardly are formed at positions close to the annular projectingportions 7a and 8a of theshells 7 and 8 while being spaced apart in the front-rear direction.

An outlet passage R2 that communicates with the end side and communicates with thedischarge port 4 is formed.

その他、本実施例１のアウターフィン６には波の頂部と谷部との間に複数のルーバ６ａ（図１２参照）が形成されているが、この限りでない。  In addition, although the plurality oflouvers 6a (see FIG. 12) are formed in theouter fin 6 of the first embodiment between the wave top and the valley, this is not restrictive.

また、本実施例１の車両用熱交換器１を構成する全ての構成部材はアルミ製であり、各構成部材が接合する接合部のうち、少なくとも一方側にはろう材から成るクラッド層（ブレージングシート）が設けられ、これらは予め仮組みされた状態で図外の加熱炉に搬送されて熱処理されることにより各接合部が一体的にろう付け固定されている。
なお、車両用熱交換器１の詳細な部位の形状、形成数、形成位置等については適宜設計変更可能である。In addition, all the constituent members constituting the vehicle heat exchanger 1 of the first embodiment are made of aluminum, and at least one side of the joint portion to which each constituent member is joined is a clad layer (brazing brazing material). Sheets) are provided, and these are transported to a heating furnace (not shown) in a pre-assembled state and heat-treated, whereby each joint is integrally brazed and fixed.
In addition, about the shape of the detailed site | part of the heat exchanger 1 for vehicles, the number of formation, a formation position, etc., a design change is possible suitably.

図８〜１０に示すように、保護部材２０は車両用熱交換器１のコア部２の長手方向の長さと同じ長さを有する複数の保護部２１と、各保護部２１の両端部同士を上下方向に結合する結合部22,23を備えて樹脂で一体的に形成されている。  As shown in FIGS. 8 to 10, theprotection member 20 includes a plurality ofprotection portions 21 having the same length as the length of thecore portion 2 of the vehicle heat exchanger 1 and both end portions of eachprotection portion 21. Thecoupling portions 22 and 23 coupled in the vertical direction are provided and are integrally formed of resin.

図２に示すように、各保護部２１は車両用熱交換器１のコア部２の各チューブ５にそれぞれ対応した位置に設けられる他、図１１に示すように、車両前方側に先細りした頂点２１ａ部分を有する三角形断面形状に形成され、これによって隣接する保護部２１同士における後端部２１ｂ同士間の開口幅Ｗ３が前端部２１ａ同士間の開口幅Ｗ４よりも小さくなっている。
また、各保護部２１の前後方向の寸法Ｈ、後面２１ｄの上下方向の寸法Ｗ、頂点２１ａの角度αは適宜設定できるが、少なくとも上記寸法Ｗは車両用熱交換器２のチューブ５の上下方向の寸法以上の長さとなっている。As shown in FIG. 2, eachprotection portion 21 is provided at a position corresponding to eachtube 5 of thecore portion 2 of the vehicle heat exchanger 1, and as shown in FIG. 11, the apex is tapered toward the front side of the vehicle. The opening width W3 between therear end portions 21b in theadjacent protection portions 21 is smaller than the opening width W4 between thefront end portions 21a.
Moreover, although the dimension H of the front-back direction of eachprotection part 21, the dimension W of the up-down direction of therear surface 21d, and the angle α of theapex 21a can be set as appropriate, at least the dimension W is the vertical direction of thetube 5 of thevehicle heat exchanger 2. It is longer than the dimension of.

さらに、図９、１０に示すように、結合部22,23の後面には後方へ円柱状に突出した固定部２４が複数（本実施例では３カ所）形成されると共に、各固定部２４の先端には上下方向に突出した円柱状のピン24a,24bが形成されている。  Further, as shown in FIGS. 9 and 10, a plurality of fixing portions 24 (three in this embodiment) are formed on the rear surfaces of the connectingportions 22 and 23 so as to protrude rearward in a columnar shape.Cylindrical pins 24a and 24b projecting in the vertical direction are formed at the tip.

そして、各固定部２４のピン24a,24bが車両用熱交換器２のそれぞれ対応するシェル7,8のエンボス部１０に嵌合されることにより、車両用熱交換器１のコア部２の前方側に保護部材２０が固定されている（図２参照）。
従って、各エンボス部１０の内側でインナーフィン９を押圧して位置決めできると同時に、各エンボス部１０の外側に固定部２４のそれぞれ対応するピン24a,24bを嵌合させて固定できるようになっている。
また、この際、保護部材２０の各保護部２１がそれぞれ対応するチューブ５を覆う他、隣接する保護部２１の後端部２１ｂ同士間にそれぞれ対応するアウターフィン６が配置されることとなる。Then, thepins 24a and 24b of eachfixing portion 24 are fitted to the embossedportions 10 of thecorresponding shells 7 and 8 of thevehicle heat exchanger 2, respectively, so that the front of thecore portion 2 of the vehicle heat exchanger 1 is obtained. Theprotective member 20 is fixed to the side (see FIG. 2).
Accordingly, theinner fin 9 can be pressed and positioned inside each embossedportion 10, and at the same time, thecorresponding pins 24 a and 24 b of thefixing portion 24 can be fitted and fixed to the outside of each embossedportion 10. Yes.
At this time, each of theprotection portions 21 of theprotection member 20 covers thecorresponding tube 5, and the correspondingouter fin 6 is disposed between therear end portions 21 b of theadjacent protection portions 21.

なお、本実施例１では車両用熱交換器１の各チューブ５と保護部材２０との間には僅かな隙間Ｗ５（図１２に参照）が形成されているが、これら両者は当接させても良い。  In the first embodiment, a slight gap W5 (see FIG. 12) is formed between eachtube 5 of the vehicle heat exchanger 1 and theprotective member 20, but these two are in contact with each other. Also good.

次に、作用を説明する。
このように構成されたインタークーラは、図７に示すように、図外の過給機で圧縮された１６０℃前後の吸入空気（波線矢印で図示）が、吸入ポート３から入口通路Ｒ１に流入し、各チューブ５内を流通して出口通路Ｒ２に流入する間に、アウターフィン６を介して車両走行風または図外のファンによる強制風と熱交換して４０℃前後まで冷却された後、排出ポート４から排出されてエンジンへ流入する。Next, the operation will be described.
In the intercooler configured as described above, as shown in FIG. 7, intake air of about 160 ° C. (illustrated by a wavy arrow) compressed by a supercharger (not shown) flows from theintake port 3 into the inlet passage R1. Then, while flowing through eachtube 5 and flowing into the outlet passage R2, it is cooled to around 40 ° C. by exchanging heat with vehicle running wind or forced wind by a fan outside the figure through theouter fin 6. It is discharged from thedischarge port 4 and flows into the engine.

この際、図１２に示すように、上記車両走行風または図外のファンによる強制風Ｚは、各保護部２１の頂点２１ａから上下方向に分かれて各傾斜部２１ｄに沿ってそれぞれ対応するアウターフィン６へスムーズに進入する。  At this time, as shown in FIG. 12, the vehicle running wind or the forced wind Z generated by a fan not shown in the drawing is separated from theapex 21a of eachprotection portion 21 in the vertical direction and corresponds to the corresponding outer fin along eachinclined portion 21d. Enter 6 smoothly.

従って、各保護部２１は上記風Ｚをアウターフィン６へスムーズに導く導風機能を果たすことができる。  Therefore, eachprotection part 21 can fulfill the function of guiding the wind Z to theouter fin 6 smoothly.

また、前方からコア部２へ飛んできた飛び石等の攻撃物を保護部２１で保護でき、チューブ５の破損・亀裂を防止できる。
この際、斜め前方から所定の角度α１で攻撃物Ｘがコア部２へ向かって飛んできた場合にも保護部５でコア部２、特にコア部２のチューブ５を確実に保護できる。
また、上記攻撃物Ｘが角度α１よりも小さい角度、つまり、水平方向に近い角度でコア部２へ飛んできた場合は、各保護部２１同士間を通過しようとするが、前述したように、隣接する保護部２１同士における後端部２１ｂ同士間の開口幅Ｗ３が前端２１ｃ同士間の開口幅Ｗ４よりも小さくなっているため、開口幅Ｗ３よりも大きな攻撃物が保護部２１同士間を通過する虞がなく、コア部２の損傷を最小限に留めることができる。
また、例え開口幅Ｗ３よりも小さい攻撃物であっても該攻撃物はアウターフィン６に衝突するため、チューブ５が破損する虞がない。Further, an attacking object such as a stepping stone flying from the front to thecore portion 2 can be protected by theprotection portion 21, and thetube 5 can be prevented from being damaged or cracked.
At this time, even when the attack object X flies toward thecore portion 2 at a predetermined angle α1 from obliquely forward, theprotection portion 5 can reliably protect thecore portion 2, particularly thetube 5 of thecore portion 2.
In addition, when the attack object X flies to thecore part 2 at an angle smaller than the angle α1, that is, at an angle close to the horizontal direction, it tries to pass between theprotective parts 21, but as described above, Since the opening width W3 between therear end portions 21b between theadjacent protection portions 21 is smaller than the opening width W4 between the front ends 21c, an attack larger than the opening width W3 passes between theprotection portions 21. There is no risk of this, and damage to thecore portion 2 can be kept to a minimum.
Further, even if the attacking object is smaller than the opening width W3, the attacking object collides with theouter fin 6, so that thetube 5 is not damaged.

次に、効果を説明する。
以上、説明したように、本実施例１の車両用熱交換器の保護部材構造にあっては、交互に配置された複数のチューブ５とアウターフィン６でコア部２が構成されると共に、このコア部２の前面に保護部材２０が設けられた車両用熱交換器１の保護部材構造において、保護部材２０が、コア部２の各チューブ５の前方側を覆った状態で該チューブ５の長手方向に延在し、且つ、車両斜め前方からコア部２へ向かう攻撃物Ｘと該コア部２との衝突を防止する保護部２１を備えるため、各チューブ５を確実に保護できると同時に車両斜め前方からコア部２へ向かう攻撃物Ｘとコア部２の衝突を防止できる。Next, the effect will be described.
As described above, in the protection member structure for a vehicle heat exchanger according to the first embodiment, thecore portion 2 is configured by a plurality of alternately arrangedtubes 5 andouter fins 6. In the protection member structure of the vehicle heat exchanger 1 in which theprotection member 20 is provided on the front surface of thecore portion 2, the longitudinal direction of thetube 5 is such that theprotection member 20 covers the front side of eachtube 5 of thecore portion 2. Since each of thetubes 5 can be reliably protected and at the same time oblique to the vehicle, it is provided with theprotection portion 21 that extends in the direction and prevents the collision X with the attacking object X heading toward thecore portion 2 from the oblique front of the vehicle. Collision between the attacking object X heading from the front toward thecore part 2 and thecore part 2 can be prevented.

また、隣接する保護部２１同士における後端部２１ｂ同士間の開口幅Ｗ３が前端部２１ａ同士間の開口幅Ｗ４よりも小さくなるように各保護部２１の断面形状を形成したため、導風効果を得ることができると共に、開口幅Ｗ３よりも大きな攻撃物の保護部２１同士間への通過を防止できる。  Moreover, since the cross-sectional shape of eachprotection part 21 was formed so that the opening width W3 between therear end parts 21b in theadjacent protection parts 21 was smaller than the opening width W4 between thefront end parts 21a, the wind guide effect was achieved. In addition to being able to obtain, it is possible to prevent an attacking object larger than the opening width W3 from passing between theprotection parts 21.

また、各保護部２１の断面形状を車両前方側に先細りした略三角形断面形状に形成したため、上記風Ｚを効率よく導風するのに適した形状の保護部２１となる。  Moreover, since the cross-sectional shape of eachprotection part 21 was formed in the substantially triangular cross-sectional shape tapering to the vehicle front side, it becomes theprotection part 21 of the shape suitable for guiding the said wind Z efficiently.

また、車両用熱交換器１の各チューブ５の内部にインナーフィン９を介装すると共に、このインナーフィン９を各チューブ５に設けられたエンボス部１０によって位置決めし、保護部材２０にエンボス部１０と嵌合する固定部２４を設けて該保護部材２０と車両用熱交換器１を固定したため、エンボス部１０をインナーフィン９の位置決めと、保護部材２０の固定の両方に兼用できる。  In addition, aninner fin 9 is interposed inside eachtube 5 of the vehicle heat exchanger 1, and theinner fin 9 is positioned by an embossedportion 10 provided on eachtube 5, and the embossedportion 10 is provided on theprotective member 20. Since theprotective member 20 and the vehicle heat exchanger 1 are fixed by providing the fixingportion 24 to be fitted, the embossedportion 10 can be used both for positioning theinner fin 9 and fixing theprotective member 20.

以下、実施例２を説明する。
本実施例２において実施例１と同一形状の構成部材については同じ符号を付してその説明は省略し、相違点のみ詳述する。Example 2 will be described below.
In the second embodiment, constituent members having the same shape as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and only differences are described in detail.

図１３は本実施例２の保護部の断面形状を説明する図である。  FIG. 13 is a diagram for explaining the cross-sectional shape of the protective portion of the second embodiment.

図１３に示すように、本実施例２の車両用熱交換器の保護部材構造では、各保護部３０が前方側に円弧形状を有する略半円形断面形状に形成されている点が実施例と異なる。  As shown in FIG. 13, in the protection member structure for a vehicle heat exchanger according to the second embodiment, eachprotection portion 30 is formed in a substantially semicircular cross-sectional shape having an arc shape on the front side. Different.

従って、実施例１と同様の効果を得ることができる他、保護部３０に必要な材料を削減して軽量化できる上、前方側に尖った部位がないため、攻撃物が保護部３０に刺さって付着する虞がないという利点を有する。  Therefore, in addition to obtaining the same effect as that of the first embodiment, the material required for theprotection part 30 can be reduced and the weight can be reduced, and since there is no pointed portion on the front side, the attacking object is stuck in theprotection part 30. There is an advantage that there is no risk of adhesion.

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、車両用熱交換器はインタークーラに限らず、ラジエータ、コンデンサ、ラジエータとコンデンサが一体的に固設された一体型熱交換器、オイルクーラ等の一般的な全ての車両用熱交換器に適用可能である。
また、保護部の断面形状は略三角形断面形状や略半円形状に限らず、適宜設定できる。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, a vehicle heat exchanger is not limited to an intercooler, but can be applied to all general vehicle heat exchangers such as a radiator, a condenser, an integrated heat exchanger in which a radiator and a condenser are integrally fixed, and an oil cooler. Applicable.
Moreover, the cross-sectional shape of the protection part is not limited to a substantially triangular cross-sectional shape or a substantially semicircular shape, and can be set as appropriate.
