Description

この発明は車両用インタークーラの冷却装置に係り、特にインタークーラの冷却性能の向上を図るとともに、インタークーラの剛性の向上をも図る車両用インタークーラの冷却装置に関するものである。   The present invention relates to a vehicular intercooler cooling apparatus, and more particularly to a vehicular intercooler cooling apparatus that improves the cooling performance of the intercooler and also improves the rigidity of the intercooler.

車両用インタークーラは、走行風を通過させることで吸気を冷却し、エンジンへの充填効率を高める役割を果たす部品である。
そのため、前記インタークーラは、走行風が通過し易い設計とすることが重要である。 The vehicle intercooler is a part that plays a role of cooling the intake air by allowing the traveling wind to pass therethrough and increasing the charging efficiency of the engine.
For this reason, it is important that the intercooler is designed to allow traveling wind to easily pass therethrough.

特開平６−１９１２９３号公報JP-A-6-191293

ところで、従来の車両用インタークーラの冷却装置において、ラジエータファンを通過する風（「ラジエータファン風」ともいう。）は、前記インタークーラを通過する冷却風と比較して風速が早く、その影響によってインタークーラ背面へと巻き込まれる流れとなっている。
この流れは、インタークーラを通過する冷却風の妨げとなっており、冷却効率を低下させる原因となっているという不都合がある。 By the way, in the conventional vehicle intercooler cooling device, the wind passing through the radiator fan (also referred to as “radiator fan wind”) has a higher wind speed than the cooling wind passing through the intercooler. It is a flow that gets involved in the back of the intercooler.
This flow hinders the cooling air passing through the intercooler and has the disadvantage of causing a reduction in cooling efficiency.

また、一般的に、ラジエータを通過してラジエータファンの回転で車両後方に流れ込んだ走行風は、ラジエータファンの径方向に徐々に広がるように車両後方に流れる。
そこで、上記の特許文献１に記載されるように、ラジエータの車両後方で、かつ、変速機の上方にインタークーラにラジエータを通過した走行風が流れないようにするために、ラジエータとインタークーラとの間に配管を配設したものがあった。
しかし、この特許文献１に開示される構造では、ラジエータを通過した走行風が配管の外周を沿ってすり抜けてインタークーラのコア部の後面に流れ込んで、ラジエータを通過した走行風とインタークーラを通過した風とがインタークーラの後面近傍で合流してしまう。その結果、インタークーラの後面で走行風の流れが乱れて、インタークーラの通風性を低下させる虞がある。 In general, the traveling wind that passes through the radiator and flows into the rear of the vehicle by the rotation of the radiator fan flows toward the rear of the vehicle so as to gradually spread in the radial direction of the radiator fan.
Therefore, as described in Patent Document 1, the radiator and the intercooler are arranged in order to prevent the traveling wind that has passed through the radiator to the intercooler from behind the radiator and above the transmission. There was one in which piping was arranged between.
However, in the structure disclosed in Patent Document 1, the traveling wind that has passed through the radiator passes through the outer periphery of the pipe and flows into the rear surface of the core portion of the intercooler, and passes through the traveling wind that has passed through the radiator and the intercooler. The wind has joined the vicinity of the rear surface of the intercooler. As a result, the flow of the traveling wind is disturbed on the rear surface of the intercooler, and there is a possibility that the air permeability of the intercooler is lowered.

この発明は、車両用インタークーラの冷却装置において、インタークーラの冷却性能を向上させるとともに、インタークーラの剛性を高めることを目的とする。   An object of the present invention is to improve the cooling performance of an intercooler and to increase the rigidity of the intercooler in a vehicular intercooler cooling device.

そこで、この発明は、上述不都合を除去するために、エンジンルームに過給機を備えるエンジンと変速機とを車両幅方向に並べて配置し、前記変速機の前方にラジエータファンを取り付けたラジエータを配置し、吸気を冷却するコア部の上側および下側に夫々タンク部を備えるインタークーラを、このインタークーラの車両前後方向の後端部が前端部より鉛直方向で高くなるように傾斜させて、前記変速機の上方に配置し、前記インタークーラの上面側に冷却風を導入する導風ダクトを取り付けた車両用インタークーラの冷却装置において、前記コア部の下側に配置される下側タンク部に、この後面から車両後方に向けて水平方向もしくは水平方向よりも斜め下方に突出する整流板を取り付けたことを特徴とする。   Therefore, in order to eliminate the above-mentioned inconvenience, the present invention arranges an engine equipped with a supercharger in an engine room and a transmission side by side in the vehicle width direction, and arranges a radiator with a radiator fan attached in front of the transmission. Then, the intercooler provided with the tank portions respectively on the upper side and the lower side of the core portion for cooling the intake air is inclined so that the rear end portion of the intercooler in the vehicle front-rear direction is higher in the vertical direction than the front end portion, In a cooling system for a vehicle intercooler, which is disposed above a transmission and has a wind guide duct for introducing cooling air to the upper surface side of the intercooler, a lower tank portion disposed below the core portion A rectifying plate is attached that protrudes from the rear surface toward the rear of the vehicle in the horizontal direction or obliquely below the horizontal direction.

以上詳細に説明した如くこの発明によれば、エンジンルームに過給機を備えるエンジンと変速機とを車両幅方向に並べて配置し、変速機の前方にラジエータファンを取り付けたラジエータを配置し、吸気を冷却するコア部の上側および下側に夫々タンク部を備えるインタークーラを、このインタークーラの車両前後方向の後端部が前端部より鉛直方向で高くなるように傾斜させて、変速機の上方に配置し、インタークーラの上面側に冷却風を導入する導風ダクトを取り付けた車両用インタークーラの冷却装置において、コア部の下側に配置される下側タンク部に、この後面から車両後方に向けて水平方向もしくは水平方向よりも斜め下方に突出する整流板を取り付ける。
従って、上述した構造では、前記整流板によってインタークーラの下側に形成される空間とインタークーラのコア部の後面近傍の空間とを鉛直方向で仕切ることができる。
そして、前記整流板によって、車両前方から導入されてラジエータファンによって車両後方に向けて流れる冷却風がインタークーラのコア部の後面側に回り込まないように防止できる。
これにより、前記ラジエータを通過してラジエータファンによって車両後方に流れる冷却風と導風ダクトに導入されてインタークーラのコア部を通過した冷却風とが前記整流板でコア部の後面近傍で合流するのを防止でき、導風ダクトに導入されコア部を通過した冷却風を車両後方へとスムーズに流すことができる。
すなわち、前記整流板でコア部の後面近傍にインタークーラの下側からラジエータファンによって車両後方に流れる冷却風が流れ込むのを抑制できるため、コア部を通過する冷却風の通風性を高めて、インタークーラの冷却性を向上できる。
また、前記タンク部に前記整流板を取り付けたことで、整流板がタンク部の面剛性を向上させる補強リブの役割を果たし、タンク部の外周面の振動や変形を抑制でき、インタークーラの剛性を向上させることができる。 As described above in detail, according to the present invention, an engine equipped with a supercharger in an engine room and a transmission are arranged side by side in the vehicle width direction, a radiator with a radiator fan attached to the front of the transmission, The intercooler having tank portions on the upper side and lower side of the core portion for cooling the vehicle is inclined so that the rear end portion of the intercooler in the vehicle front-rear direction is higher in the vertical direction than the front end portion. In a cooling system for a vehicle intercooler in which a wind guide duct for introducing cooling air is installed on the upper surface side of the intercooler, the rear tank portion is disposed on the lower tank portion disposed on the lower side of the core portion. A rectifying plate that projects horizontally or obliquely below the horizontal direction is attached.
Therefore, in the structure described above, the space formed below the intercooler by the current plate and the space near the rear surface of the core portion of the intercooler can be partitioned in the vertical direction.
The rectifying plate can prevent the cooling air introduced from the front of the vehicle and flowing toward the rear of the vehicle by the radiator fan from entering the rear surface of the core portion of the intercooler.
As a result, the cooling air that passes through the radiator and flows to the rear of the vehicle by the radiator fan and the cooling air that is introduced into the air guide duct and passes through the core portion of the intercooler merges in the vicinity of the rear surface of the core portion at the rectifying plate. Therefore, the cooling air introduced into the air guide duct and passing through the core portion can be smoothly flowed to the rear of the vehicle.
In other words, since the cooling air flowing from the lower side of the intercooler to the rear of the vehicle by the radiator fan can be prevented from flowing into the vicinity of the rear surface of the core portion by the rectifying plate, the ventilation performance of the cooling air passing through the core portion can be improved. The cooling performance of the cooler can be improved.
Further, by attaching the current plate to the tank portion, the current plate serves as a reinforcing rib that improves the surface rigidity of the tank portion, and vibration and deformation of the outer peripheral surface of the tank portion can be suppressed, and the rigidity of the intercooler can be suppressed. Can be improved.

更に、前記インタークーラ１６のコア部１３の下側に配置される前記下側タンク部１５に、この後面から車両後方に向けて水平方向もしくは水平方向よりも斜め下方に突出する整流板２２を取り付ける構成とする。
詳述すれば、前記インタークーラ１６の下側タンク部１５には、図１及び図２、図５〜図８に夫々示す如く、下側タンク部１５の後面から車両後方に向けて水平方向もしくは水平方向よりも斜め下方、この実施例においては、水平方向よりも斜め下方に突出するように前記整流板２２を取り付けるものである。
従って、上述した構造では、前記整流板２２によって前記インタークーラ１６の下側に形成される空間とインタークーラ１６のコア部１３の後面近傍の空間とを鉛直方向で仕切ることができる。
そして、前記整流板２２によって、車両前方から導入されて前記ラジエータファン１１によって車両後方に向けて流れる冷却風が、図５及び図７、図８に太い斜線付矢印で示す如く、前記インタークーラ１６のコア部１３の後面側に回り込まないように防止できる。
これによって、図５及び図７、図８に太い斜線付矢印で示す如く、前記ラジエータ１２を通過してラジエータファン１１によって車両後方に流れる冷却風と、図５及び図７、図８に太い白抜き矢印で示す如く、前記導風ダクト１７に導入されてインタークーラ１６のコア部１３を通過した冷却風とが、前記整流板２２でコア部１３の後面近傍で合流するのを防止でき、導風ダクト１７に導入されコア部１３を通過した冷却風を車両後方へとスムーズに流すことができる。
よって、前記整流板２２でコア部１３の後面近傍に前記インタークーラ１６の下側からラジエータファン１１によって車両後方に流れる冷却風が流れ込むのを抑制できるため、コア部１３を通過する冷却風の通風性を高め、インタークーラ１６の冷却性能を向上させることができる。
また、前記下側タンク部１５に前記整流板２２を取り付けたことで、整流板２２が下側タンク部１５の面剛性を向上させる補強リブの役割を果たし、下側タンク部１５の外周面の振動や変形を抑制でき、インタークーラ１６の剛性を向上させることができる。 Further, a rectifying plate 22 is attached to the lower tank portion 15 disposed below the core portion 13 of the intercooler 16 so as to protrude from the rear surface toward the rear of the vehicle in the horizontal direction or obliquely downward from the horizontal direction. The configuration.
More specifically, the lower tank portion 15 of the intercooler 16 has a horizontal direction from the rear surface of the lower tank portion 15 toward the rear of the vehicle, as shown in FIGS. 1, 2, and 5 to 8. The rectifying plate 22 is attached so as to protrude obliquely downward from the horizontal direction, in this embodiment, obliquely downward from the horizontal direction.
Therefore, in the structure described above, the space formed below the intercooler 16 by the rectifying plate 22 and the space near the rear surface of the core portion 13 of the intercooler 16 can be partitioned in the vertical direction.
Then, the cooling air introduced from the front of the vehicle by the current plate 22 and flowing toward the rear of the vehicle by the radiator fan 11, as shown by thick hatched arrows in FIGS. 5, 7, and 8, the intercooler 16. It is possible to prevent the core portion 13 from going around to the rear side.
As a result, as shown by thick hatched arrows in FIGS. 5, 7, and 8, the cooling air that passes through the radiator 12 and flows to the rear of the vehicle by the radiator fan 11, and the thick white in FIGS. 5, 7, and 8. As indicated by the drawing arrow, it is possible to prevent the cooling air introduced into the air guide duct 17 and passing through the core portion 13 of the intercooler 16 from being merged in the vicinity of the rear surface of the core portion 13 by the rectifying plate 22. Cooling air that has been introduced into the wind duct 17 and passed through the core portion 13 can flow smoothly toward the rear of the vehicle.
Therefore, the flow of the cooling air passing through the core portion 13 can be suppressed because the flow of the cooling air flowing to the rear of the vehicle by the radiator fan 11 from the lower side of the intercooler 16 can be suppressed by the rectifying plate 22 in the vicinity of the rear surface of the core portion 13. The cooling performance of the intercooler 16 can be improved.
Further, by attaching the rectifying plate 22 to the lower tank portion 15, the rectifying plate 22 serves as a reinforcing rib that improves the surface rigidity of the lower tank portion 15, and the outer peripheral surface of the lower tank portion 15 is Vibration and deformation can be suppressed, and the rigidity of the intercooler 16 can be improved.

前記整流板２２は、前記下側タンク部１５の車両上下方向中央部に配置するとともに、その車両幅方向両端部を前記下側タンク部１５の車両幅方向両端部まで延ばした構成とする。
つまり、前記下側タンク部１５において、図１及び図２に示す如く、この下側タンク部１５の車両上下方向中央部に前記整流板２２を配置する。
このとき、前記整流板２２の車両幅方向両端部を前記下側タンク部１５の車両幅方向両端部まで延ばしている。
従って、上述した構造によって、前記整流板２２の車両幅方向両端部を前記下側タンク部１５のうち比較的剛性の高い車両幅方向の両端部近傍まで延ばし、下側タンク部１５のうち面剛性が最も低い中央部を車両幅方向に横断させることで、前記整流板２２が補強リブの役割を果たして下側タンク部１５の中央部の面剛性を高めることができる。
これによって、下側タンク部１５の振動や変形を抑制でき、インタークーラ１６の剛性を向上させることができる。 The rectifying plate 22 is disposed at the center of the lower tank portion 15 in the vehicle vertical direction, and has both ends in the vehicle width direction extending to both ends in the vehicle width direction of the lower tank portion 15.
That is, in the lower tank portion 15, as shown in FIGS. 1 and 2, the rectifying plate 22 is arranged at the vehicle vertical direction center portion of the lower tank portion 15.
At this time, both ends of the rectifying plate 22 in the vehicle width direction are extended to both ends of the lower tank portion 15 in the vehicle width direction.

つまり、前記上側タンク部１４は、図１及び図２、図６、図７に示す如く、前記エンジン７に取り付けられる上側取付部２４を有する一方、前記下側タンク部１５は、図１及び図２、図６〜図８に示す如く、その底部に車両下方に突出するとともに弾性部材２５を介して前記エンジン７に取り付けられる前記下側取付部２３を有している。
このとき、この下側取付部２３には、図１及び図２に示す如く、前記整流板２２の端部を車両下方に延長させて補強リブとして機能する補強用延長部２６を連結している。
一般的に、重量物であるインタークーラ１６が振動することで、前記エンジン７に連絡する上側取付部２４や下側取付部２３にインタークーラ１６の振動が伝達されて、取付部、特に下側に位置する下側取付部２３に局所的な応力が集中する。
そこで、本発明の上述した構造によって、前記下側取付部２３の上端部に整流板２２を連結することで、整流板２２が補強部材の役割を果たして、下側取付部２３に局所的に集中する応力を緩和させることができる。
これによって、インタークーラ１６の下側取付部２３の剛性を高めることができ、インタークーラ１６を安定してエンジン７に取り付けることができる。 Further, the lower tank portion 15 has a mounting portion (hereinafter referred to as “lower mounting portion”) 23 that protrudes below the vehicle and is attached to the engine 7 at the bottom thereof.
That is, the upper tank portion 14 has an upper attachment portion 24 attached to the engine 7 as shown in FIGS. 1, 2, 6, and 7, while the lower tank portion 15 is similar to FIGS. 2. As shown in FIG. 6 to FIG. 8, the bottom mounting portion 23 that protrudes downward from the vehicle and is attached to the engine 7 via an elastic member 25 is provided at the bottom thereof.
At this time, as shown in FIGS. 1 and 2, the lower mounting portion 23 is connected to a reinforcing extension portion 26 that functions as a reinforcing rib by extending the end portion of the rectifying plate 22 below the vehicle. .
Generally, when the intercooler 16 that is a heavy object vibrates, the vibration of the intercooler 16 is transmitted to the upper mounting portion 24 and the lower mounting portion 23 that communicate with the engine 7, and the mounting portion, particularly the lower side, is transmitted. Local stress concentrates on the lower mounting portion 23 located at the position.
Therefore, by connecting the rectifying plate 22 to the upper end portion of the lower mounting portion 23 according to the above-described structure of the present invention, the rectifying plate 22 serves as a reinforcing member and is locally concentrated on the lower mounting portion 23. Stress to be relieved.
Thereby, the rigidity of the lower attachment portion 23 of the intercooler 16 can be increased, and the intercooler 16 can be stably attached to the engine 7.

更に、前記下側タンク部１５を、上述したように前記過給機６から圧送される吸気を導入する入口側のタンク部としている。
一般的に、前記過給機６から吸気がインタークーラ１６に導入される入口側のタンク部は、吸気が排出される出口側のタンク部に比べて、過給機６の圧送による吸気の導入によってタンク部が振動し易くなる。
そこで、本発明の上述した構造によって、前記下側タンク部１５を入口側のタンク部としたことで、振動あるいは変形し易い側のタンク部に前記整流板２２を取り付けることができ、下側タンク部１５の振動や変形を抑制できる。 Further, the lower tank portion 15 is an inlet-side tank portion for introducing the intake air pumped from the supercharger 6 as described above.
In general, the inlet side tank portion where the intake air from the supercharger 6 is introduced into the intercooler 16 is introduced as compared with the outlet side tank portion where the intake air is discharged. As a result, the tank part easily vibrates.
Therefore, with the above-described structure of the present invention, the lower tank portion 15 is an inlet-side tank portion, so that the rectifying plate 22 can be attached to the tank portion on the side that is easily vibrated or deformed. The vibration and deformation of the part 15 can be suppressed.

前記ラジエータ１２の後側に前記ラジエータファン１１の外周を囲む円筒状の円筒部２７を備えたファンシュラウド２８を取り付ける構成とする。
つまり、前記ラジエータ１２の後側に、図３〜図８に示す如く、ファンシュラウド２８を取り付け、このファンシュラウド２８の円筒部２７によって前記ラジエータファン１１の外周を囲んでいる。
これにより、本発明の上述した構造によって、前記ラジエータ１２を通過して前記ラジエータファン１１によって円筒部２７で車両後方に案内される冷却風がコア部１３の後面に流れ込まないよう確実に防止できる。 A fan shroud 28 having a cylindrical cylindrical portion 27 that surrounds the outer periphery of the radiator fan 11 is attached to the rear side of the radiator 12.
That is, as shown in FIGS. 3 to 8, a fan shroud 28 is attached to the rear side of the radiator 12, and the outer periphery of the radiator fan 11 is surrounded by the cylindrical portion 27 of the fan shroud 28.
Thereby, according to the above-described structure of the present invention, it is possible to reliably prevent the cooling air that passes through the radiator 12 and is guided to the rear of the vehicle by the cylindrical portion 27 by the radiator fan 11 from flowing into the rear surface of the core portion 13.

図９はこの発明の第２実施例を示すものである。
この第２実施例において、上述第１実施例のものと同一機能を果たす箇所には、同一符号を付して説明する。 FIG. 9 shows a second embodiment of the present invention.
In the second embodiment, portions that perform the same functions as those of the first embodiment will be described with the same reference numerals.

この第２実施例の特徴とするところは、前記整流板３１の下端３１ａを前記円筒部２７の上端部２７ｔの高さ位置まで延ばした構成とした点にある。   The feature of the second embodiment is that the lower end 31a of the rectifying plate 31 is extended to the height position of the upper end portion 27t of the cylindrical portion 27.

すなわち、前記ラジエータ１２の後側に前記ラジエータファンの外周を囲む円筒状の円筒部２７を備えたファンシュラウド２８を取り付けた際に、鉛直方向において前記整流板３１の下端３１ａを、図９に示す如く、前記円筒部２７の上端部２７ｔの高さ位置まで延ばし、ほぼ同等の高さ位置とするものである。
さすれば、本発明の上述した構造によって、前記ラジエータ１２を通過して前記ラジエータファンによって円筒部２７で車両後方に案内される冷却風がコア部１３の後面に確実に流れ込まないように防止できる。また、前記整流板３１は、前記ラジエータファンによって車両後方に送り出される冷却風の流れを阻害することがない。このため、前記ラジエータ１２を通過した冷却風の通風性を良好にできる。 That is, when a fan shroud 28 having a cylindrical cylindrical portion 27 surrounding the outer periphery of the radiator fan is attached to the rear side of the radiator 12, the lower end 31a of the current plate 31 in the vertical direction is shown in FIG. As described above, the cylindrical portion 27 is extended to the height position of the upper end portion 27t so as to have substantially the same height position.
In other words, according to the above-described structure of the present invention, it is possible to prevent the cooling air that passes through the radiator 12 and is guided to the rear of the vehicle by the cylindrical portion 27 by the radiator fan from reliably flowing into the rear surface of the core portion 13. . Moreover, the said baffle plate 31 does not obstruct the flow of the cooling wind sent out to the vehicle rear by the said radiator fan. For this reason, the ventilation property of the cooling air that has passed through the radiator 12 can be improved.
