First, the overall configuration will be described.
As shown in FIGS. 1 and 2, in the air duct structure of the heat exchanger according to the first embodiment, the radiator core support 1 accommodated in the engine room in the front portion of the vehicle and the radiator core support 1 are fixedly supported in front of the radiator core support 1. A heat exchanger 2 and an air duct 3 disposed in front of the heat exchanger 2 are provided.
熱交換器２は、それぞれ上下一対のタンク4,4（一部省略）を備える２つのコア部5a,5bが左右に隣接した状態で一体的に固設されたインタークーラが採用される他、各タンク4,4の側方にはその内部と連通接続された状態で後方へ延設された入出力パイプ6,6がそれぞれ設けられている。 The heat exchanger 2 employs an intercooler in which two core portions 5a and 5b each provided with a pair of upper and lower tanks 4 and 4 (partially omitted) are integrally fixed in a state adjacent to the left and right, Input / output pipes 6 and 6 are provided on the sides of the tanks 4 and 4 so as to extend rearward while being connected to the inside of the tanks 4 and 4, respectively.
また、熱交換器２は、前方斜め下方へ傾斜した状態で図外のブラケットによりラジエータコアサポート１に固定支持されている。
なお、熱交換器２はインタークーラに限らず、ラジエータ、コンデンサ、オイルクーラ等の一般的な全ての熱交換器に適用しても良い。
In addition, the heat exchanger 2 is fixedly supported on the radiator core support 1 by a bracket (not shown) in a state where the heat exchanger 2 is inclined obliquely forward and downward.
The heat exchanger 2 is not limited to an intercooler, and may be applied to all general heat exchangers such as a radiator, a condenser, and an oil cooler.
以下、エアダクト３について詳述する。
図３〜５に示すように、エアダクト３は、比較的柔軟な低密度樹脂等の素材を用いて車幅方向に長い略矩形の筒状に形成される他、その内部には後述するグリル７（請求項の補強部に相当）が設けられている。
Hereinafter, the air duct 3 will be described in detail.
As shown in FIGS. 3 to 5, the air duct 3 is formed in a substantially rectangular cylindrical shape that is long in the vehicle width direction using a material such as a relatively soft low-density resin, and a grill 7, which will be described later, is formed inside the air duct 3. (Corresponding to the reinforcing portion in the claims) is provided.
エアダクト３の前端部には、略台形状の開口部８が形成されると共に、該開口部８は、図６に示すように、図外のバンパアーマチュア（請求項のバンパーに相当）の外面と一体的に形成され、且つ、エアガイドを兼ねるバンパフェイシア９（請求項の該車両前方外壁面に相当）の導風開口部９ａに臨んだ状態で配置されている。 A substantially trapezoidal opening 8 is formed at the front end of the air duct 3, and the opening 8 has an outer surface of a bumper armature (not shown) corresponding to a bumper armature (not shown) as shown in FIG. 6. The bumper fascia 9 that is integrally formed and serves also as an air guide (corresponding to the vehicle front outer wall surface in the claims) faces the air guide opening 9a.
エアダクト３の中途部には、前端部から内側へ縮径するように絞られた形状の絞り部１０（請求項の脆弱部に相当）が設けられ、さらに、その後方は次第に拡径する拡大部１１が形成されている。 In the middle of the air duct 3, there is provided a narrowed portion 10 (corresponding to the fragile portion of the claims) having a shape that is narrowed so as to be reduced inward from the front end portion, and further, an enlarged portion that gradually expands in the rear thereof 11 is formed.
また、エアダクト３の後端部は、グリル７と、その後方の熱交換器２を配置するための切欠部１２が形成されている。 Further, a rear end portion of the air duct 3 is formed with a notch 12 for arranging the grille 7 and the heat exchanger 2 behind the grill 7.
グリル７は、熱交換器２のコア部5a,5bの前方（請求項の熱交換器入口に相当）に配置される他、図３に示すように、斜めに交差する複数の板状の格子部１３と、左右両側と中央に配置され、且つ、上下方向に延設される板状の仕切り部１４とを有して比較的硬質な樹脂等の素材を用いて一体的に形成されている。
これにより、グリル７の特に上下方向の剛性が向上している上、車両停車時における両コア部5a,5bの前方の熱干渉を中央の仕切り部１４によって低くできるようになっている。
The grill 7 is disposed in front of the core portions 5a and 5b of the heat exchanger 2 (corresponding to the heat exchanger inlet in the claims), and as shown in FIG. It is integrally formed using a material such as a relatively hard resin having a portion 13 and a plate-like partitioning portion 14 that is disposed on both the left and right sides and in the center and extends in the vertical direction. .
Thereby, the rigidity of the grill 7 in particular in the vertical direction is improved, and the thermal interference in front of both the core portions 5a and 5b when the vehicle is stopped can be lowered by the central partition portion 14.
また、グリル７は、その上端部がエアダクト３の切欠部１２に嵌合され、且つ、その下端部に設けられた複数（本実施例１では３箇所）の固定孔７ａとエアダクト３の下端部に設けられた固定孔３ａ（図６参照）にそれぞれ図外の固定部材が挿通し固定されることにより、エアダクト３に固定されるようになっている。
なお、グリル７とエアダクト３を一体的に形成しても良い。
The grill 7 has an upper end fitted into the notch 12 of the air duct 3, and a plurality of (three in the first embodiment) fixing holes 7 a provided at the lower end and the lower end of the air duct 3. A fixing member (not shown) is inserted into and fixed to a fixing hole 3a (see FIG. 6) provided in the air hole 3 to be fixed to the air duct 3.
The grill 7 and the air duct 3 may be integrally formed.
また、エアダクト３の拡大部１１の上下面には、複数の板状のリブ１５が一体的に立設され、これにより、周辺部位の剛性が向上している。 In addition, a plurality of plate-like ribs 15 are integrally provided on the upper and lower surfaces of the enlarged portion 11 of the air duct 3, thereby improving the rigidity of the peripheral portion.
従って、エアダクト３の拡大部１１付近は、比較的大きく後方へ張り出した形状となっているが、前述したグリル７とリブ１５によって形状維持が確保されている。 Therefore, the vicinity of the enlarged portion 11 of the air duct 3 has a shape that protrudes relatively rearward, but the shape maintenance is ensured by the grill 7 and the rib 15 described above.
その他、エアダクト３は、熱交換器２またはラジエータコアサポート１等の周辺部材に図外の固定部材を用いて固定されている。 In addition, the air duct 3 is fixed to a peripheral member such as the heat exchanger 2 or the radiator core support 1 using a fixing member not shown.
このように構成されたエアダクト構造では、車両走行時にバンパフェイシア９の導風開口部９ａを介してエアダクト３の開口部８から導入した車両走行風を熱交換器２のコア部5a,5bへ導くことができ、エアダクトとして機能する。 In the air duct structure configured as described above, the vehicle traveling wind introduced from the opening 8 of the air duct 3 is guided to the core portions 5a and 5b of the heat exchanger 2 through the wind guide opening 9a of the bumper fascia 9 during traveling of the vehicle. Can function as an air duct.
この際、エアダクト３内の絞り部１０を通過した車両走行風の負圧によってエアダクト３が潰れるのをグリル７とリブ１５によって防止することができる。 At this time, it is possible to prevent the air duct 3 from being crushed by the negative pressure of the vehicle traveling wind that has passed through the throttle portion 10 in the air duct 3 by the grille 7 and the rib 15.
また、エアダクト３内に進入した異物が熱交換器２のコア部5a,5bに衝突するのをグリル７の格子部１３によって防止できる。 Further, the lattice portion 13 of the grill 7 can prevent the foreign matter entering the air duct 3 from colliding with the core portions 5a and 5b of the heat exchanger 2.
そして、車両衝突時において、バンパフェイシア９に前方から衝撃力（請求項の外力に相当）が入力された場合には、図７の一点鎖線で図示するように、エアダクト３が絞り部１０を基点として速やかに変形して潰れることにより、該衝撃力をスムーズに吸収でき、これによって、熱交換器２が損傷するのを防止できる。 When an impact force (corresponding to the external force in the claims) is input from the front to the bumper fascia 9 at the time of a vehicle collision, the air duct 3 starts from the throttle portion 10 as illustrated by the one-dot chain line in FIG. As a result, the impact force can be absorbed smoothly, thereby preventing the heat exchanger 2 from being damaged.
また、本実施例１では、グリル７に上下方向に延設された仕切り部１４を形成したため、ある程度大きな応力が作用しても拡大部１１付近が上下に潰れる虞がなく、絞り部１０を確実に変形の基点とすることができ、再現性を高くすることができる。 In the first embodiment, since the partition portion 14 extending in the vertical direction is formed on the grill 7, there is no possibility that the vicinity of the enlarged portion 11 will be crushed up and down even if a large amount of stress is applied, and the throttle portion 10 is securely connected. Therefore, it can be used as a base point of deformation, and reproducibility can be improved.
次に、効果を説明する。
以上、説明したように、本実施例１の熱交換器のエアダクト構造にあっては、バンパフェイシア９の導風開口部９ａと熱交換器２を結ぶエアダクト３の途中に、該バンパフェイシア９に外力が掛かったときに速やかに変形する基点となる絞り部１０を設けたため、エアダクト３に変形の基点を設けることにより必要強度を維持しつつ、バンパフェイシア９に外力が掛かったときにその応力を吸収できる。
Next, the effect will be described.
As described above, in the air duct structure of the heat exchanger of the first embodiment, in the middle of the air duct 3 connecting the air guide opening 9a of the bumper fascia 9 and the heat exchanger 2, the bumper fascia 9 Since the throttle portion 10 is provided as a base point that quickly deforms when an external force is applied, the necessary strength is maintained by providing a base point for deformation in the air duct 3, and the stress is applied when an external force is applied to the bumper fascia 9. Can absorb.
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、補強部を格子部を交差させたグリルとしたが、格子部を並設したルーバとしても良い。
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 a scope not departing from the gist of the present invention are included in the present invention.
For example, in the first embodiment, the reinforcing portion is a grille that intersects the lattice portions, but may be a louver in which the lattice portions are arranged in parallel.
