上記文献１記載の構造では、上流側の吸気パイプと入口ヘッダー部とを接続する流路拡大部に整流プレートが設けられている。しかしながら、文献１記載の整流プレートは略横方向に延びているのみであり、該整流プレートに対して、下方に位置するチューブに吸気を十分に分配できない可能性がある。 In the structure described in Document 1 above, a rectifying plate is provided in the flow path expanding portion connecting the intake pipe on the upstream side and the inlet header portion. However, the rectifying plate described in Document 1 only extends substantially laterally, and there is a possibility that the intake air cannot be sufficiently distributed to the tube located below the rectifying plate.

In an intercooler having a core portion in which a plurality of tubes extending laterally from the inlet header portion are arranged in the vertical direction, the inside of the flow path expansion portion extends from the intake upstream side to the intake downstream side, and at least the intake downstream side. A rectifying plate having a side end extending toward the lower end side of the inlet header is provided.

また、前記流路拡大部内の前記整流プレートよりも上方に吸気上流側から吸気下流側に向かって延びる第２整流プレートをさらに備えることが好ましい。 Further, it is preferable to further include a second rectifying plate extending from the intake upstream side toward the intake downstream side above the rectifying plate in the flow path expansion portion.

図１は、本実施形態に係るインタークーラ１を模式的に示す斜視図である。 FIG. 1 is a perspective view schematically showing the intercooler 1 according to the present embodiment.

［全体構成］
インタークーラ１は、例えば、不図示の車両に搭載されたエンジンの吸気を走行風と熱交換することにより冷却するものである。具体的には、インタークーラ１は、吸気と外気との熱交換を行うコア部１０と、図示しない過給機からの吸気をコア部１０に導入する吸気導入部２０と、コア部１０から図示しないエンジンに吸気を導出する吸気導出部３０とを備えている。 [overall structure]
The intercooler 1 cools, for example, by exchanging heat with the traveling wind for the intake air of an engine mounted on a vehicle (not shown). Specifically, the intercooler 1 has a core portion 10 that exchanges heat between the intake air and the outside air, an intake intake introduction portion 20 that introduces intake air from a supercharger (not shown) into the core portion 10, and the core portion 10 as shown. It is provided with an intake intake unit 30 that derives intake air to an engine that does not.

コア部１０は、横方向（車幅方向）に延び、吸気を流通させる複数のチューブ１１を上下方向に並列に配置して構成されており、該複数のチューブ１１と、各チューブ１１間に介装された複数のアウターフィン１２と、図示しない複数の貫通孔に各チューブ１１の吸気上流端を挿通して固定する縦長の入口プレート１３と、図示しない複数の貫通孔に各チューブ１１の吸気下流端を挿通して固定する縦長の出口プレート１４とを備えている。 The core portion 10 is configured by arranging a plurality of tubes 11 extending in the lateral direction (vehicle width direction) in parallel in the vertical direction to circulate intake air, and is interposed between the plurality of tubes 11 and each tube 11. A plurality of outer fins 12 are provided, a vertically long inlet plate 13 for inserting and fixing the intake upstream end of each tube 11 through a plurality of through holes (not shown), and an intake downstream of each tube 11 through a plurality of through holes (not shown). It is provided with a vertically long outlet plate 14 through which an end is inserted and fixed.

入口プレート１３及び出口プレート１４は、その長手方向が複数のチューブ１１の軸方向と直交して、言い換えれば長手方向が各チューブ１１の配列方向となるようにして設けられている。 The inlet plate 13 and the outlet plate 14 are provided so that their longitudinal directions are orthogonal to the axial directions of the plurality of tubes 11, in other words, the longitudinal directions are the arrangement directions of the tubes 11.

吸気導入部２０は、過給機側の吸気管４１に接続されて車両前後方向に延びる入口パイプ部２１と、コア部１０の入口プレート１３に取り付けられた縦長中空状の入口ヘッダー部２２と、入口パイプ部２１と入口ヘッダー部２２とを滑らかに連結する曲面中空状の流路拡大部２３と、上側整流プレート２４と、下側整流プレート２５とを備えている。 The intake intake portion 20 includes an inlet pipe portion 21 connected to the intake pipe 41 on the supercharger side and extending in the front-rear direction of the vehicle, a vertically long hollow inlet header portion 22 attached to the inlet plate 13 of the core portion 10, and the like. It includes a curved hollow flow path expanding portion 23 that smoothly connects the inlet pipe portion 21 and the inlet header portion 22, an upper rectifying plate 24, and a lower rectifying plate 25.

流路拡大部２３は、吸気入口側から吸気出口側に向かうに従い吸気の流路面積が拡大するように形成されている。具体的には、流路拡大部２３は、入口パイプ部２１に接続されて車両前後方向に延びる第１流路２３Ａと、コア部１０の側方で第１流路２３Ａに接続されて車両幅方向に延びる第２流路２３Ｂとを備えている。 The flow path expanding portion 23 is formed so that the flow path area of the intake air expands from the intake inlet side to the intake outlet side. Specifically, the flow path expanding portion 23 is connected to the first flow path 23A which is connected to the inlet pipe portion 21 and extends in the front-rear direction of the vehicle, and the first flow path 23A which is connected to the side of the core portion 10 and is connected to the vehicle width. It is provided with a second flow path 23B extending in the direction.

第２流路２３Ｂは、入口ヘッダー部２２の側面に、入口ヘッダー部２２の上端側から長手方向（鉛直方向）の中心位置近傍に亘って車両幅方向から接続されている。また、入口パイプ部２１と第１流路２３Ａとの接続位置は、入口ヘッダー部２２の長手方向（鉛直方向）の中心位置よりも上方にオフセットしている。上側整流プレート２４と下側整流プレート２５の詳細については後述する。 The second flow path 23B is connected to the side surface of the inlet header portion 22 from the vehicle width direction from the upper end side of the inlet header portion 22 to the vicinity of the center position in the longitudinal direction (vertical direction). Further, the connection position between the inlet pipe portion 21 and the first flow path 23A is offset upward from the center position in the longitudinal direction (vertical direction) of the inlet header portion 22. Details of the upper rectifying plate 24 and the lower rectifying plate 25 will be described later.

吸気導出部３０は、コア部１０の出口プレート１４に取り付けられた縦長中空状の出口ヘッダー部３２と、エンジン側の吸気管４２に接続されて車両前後方向に延びる出口パイプ部３１と、出口パイプ部３１と出口ヘッダー部３２とを滑らかに連結する曲面中空状の流路縮小部３３とを備えている。 The intake lead-out portion 30 includes a vertically long hollow outlet header portion 32 attached to the outlet plate 14 of the core portion 10, an outlet pipe portion 31 connected to the intake pipe 42 on the engine side and extending in the front-rear direction of the vehicle, and an outlet pipe. A curved hollow flow path reducing portion 33 that smoothly connects the portion 31 and the outlet header portion 32 is provided.

流路縮小部３３は、吸気入口側から吸気出口側に向かうに従い吸気の流路面積が縮小するように形成されている。流路縮小部３３の吸気上流端は、出口ヘッダー部３２の側面に、出口ヘッダー部３２の上端側から長手方向（鉛直方向）の中心位置近傍に亘って車両幅方向から接続されている。また、出口パイプ部３１と流路縮小部３３との接続位置は、出口ヘッダー部３２の長手方向（鉛直方向）の中心位置よりも上方にオフセットしている。 The flow path reducing portion 33 is formed so that the flow path area of the intake air is reduced from the intake inlet side to the intake outlet side. The intake upstream end of the flow path reducing portion 33 is connected to the side surface of the outlet header portion 32 from the vehicle width direction from the upper end side of the outlet header portion 32 to the vicinity of the center position in the longitudinal direction (vertical direction). Further, the connection position between the outlet pipe portion 31 and the flow path reduction portion 33 is offset upward from the center position in the longitudinal direction (vertical direction) of the outlet header portion 32.

本実施形態において、コア部１０は、複数のチューブ１１の配列方向が車両上下方向（鉛直方向）に対して所定角度となるように傾斜した姿勢で車両に搭載されている。また、入口パイプ部２１及び出口パイプ部３１は、コア部１０に対してパイプの軸心方向と各チューブ１１の配列方向とのなす角度が鋭角となるように接続されている。これにより、コア部１０及び各パイプ部２１，３１を含めたインタークーラ１全体の車両上下方向の寸法が効果的に抑えられるようになっている。 In the present embodiment, the core portion 10 is mounted on the vehicle in an inclined posture so that the arrangement direction of the plurality of tubes 11 is a predetermined angle with respect to the vehicle vertical direction (vertical direction). Further, the inlet pipe portion 21 and the outlet pipe portion 31 are connected to the core portion 10 so that the angle formed by the axial direction of the pipe and the arrangement direction of each tube 11 is an acute angle. As a result, the dimensions of the entire intercooler 1 including the core portion 10 and the pipe portions 21 and 31 in the vehicle vertical direction can be effectively suppressed.

図２は、本実施形態に係るインタークーラ１の要部を部分的に切り欠いて示す模式的な斜視図である。 [Rectifying plate]
FIG. 2 is a schematic perspective view showing a main part of the intercooler 1 according to the present embodiment by partially cutting out.

図２に示すように、上側整流プレート２４（本開示の第２整流プレート）は、流路拡大部２３内に設けられており、流路拡大部２３の形状に沿うように、上方視で入口パイプ部２１側からコア部１０の側方に向かって湾曲するように形成されている。 As shown in FIG. 2, the upper rectifying plate 24 (the second rectifying plate of the present disclosure) is provided in the flow path expanding portion 23, and is an entrance when viewed upward so as to follow the shape of the flow path expanding portion 23. It is formed so as to be curved from the pipe portion 21 side toward the core portion 10.

上側整流プレート２４の上流端部２４Ａは、第１流路２３Ａ内に、その板平面が第１流路２３Ａの上側内周面と離間しながら略平行に延びるように設けられている。また、上側整流プレート２４の下流端部２４Ｂは、入口ヘッダー部２２の長手方向（鉛直方向）の中心よりも上方の第２流路２３Ｂ内に、その板平面がチューブ１１の吸気流れ方向（チューブ１１の軸方向）と略平行に延びるように、チューブ１１の吸気上流端から所定のクリアランスを隔てて設けられている。 The upstream end portion 24A of the upper rectifying plate 24 is provided in the first flow path 23A so that its plate plane extends substantially parallel to the upper inner peripheral surface of the first flow path 23A. Further, the downstream end portion 24B of the upper rectifying plate 24 is in the second flow path 23B above the center in the longitudinal direction (vertical direction) of the inlet header portion 22, and its plate plane is the intake flow direction (tube) of the tube 11. A predetermined clearance is provided from the intake upstream end of the tube 11 so as to extend substantially parallel to the axial direction of the tube 11.

下側整流プレート２５（本開示の整流プレート）は、流路拡大部２３内の上側整流プレート２４よりも下方に設けられており、流路拡大部２３の形状に沿うように、上方視で入口パイプ部２１側からコア部１０の側方に向かって湾曲するように形成されている。 The lower rectifying plate 25 (the rectifying plate of the present disclosure) is provided below the upper rectifying plate 24 in the flow path expanding portion 23, and is an entrance when viewed upward so as to follow the shape of the flow path expanding portion 23. It is formed so as to be curved from the pipe portion 21 side toward the core portion 10.

下側整流プレート２５の上流端部２５Ａは、上側整流プレート２４の上流端部２４Ａよりも下方の第１流路２３Ａ内にその板平面が第１流路２３Ａの下側内周面と離間しながら略平行に延びるように設けられている。下側整流プレート２５の下流端部２５Ｂは、上側整流プレート２４の下流端部２４Ｂよりも下方の第２流路２３Ｂ内に、その板平面（少なくとも下面）が入口ヘッダー部２２の下端側（下方）に向けて滑らかに湾曲して延びるように、チューブ１１の吸気上流端から所定のクリアランスを隔てて配置されている。 The upstream end 25A of the lower rectifying plate 25 has its plate plane separated from the lower inner peripheral surface of the first flow path 23A in the first flow path 23A below the upstream end 24A of the upper rectifying plate 24. However, it is provided so as to extend substantially in parallel. The downstream end portion 25B of the lower rectifying plate 25 is located in the second flow path 23B below the downstream end portion 24B of the upper rectifying plate 24, and its plate plane (at least the lower surface) is on the lower end side (lower side) of the inlet header portion 22. ), It is arranged with a predetermined clearance from the intake upstream end of the tube 11 so as to smoothly curve and extend.

すなわち、下流端部２５Ｂの板平面が入口ヘッダー部２２に接続された複数のチューブ１１のうち、下側に配されたチューブ１１に対して仕向けられるようになっている。これにより、流路拡大部２３内を流れる吸気を下側のチューブ１１に対して確実に分配することが可能になる。 That is, the plate plane of the downstream end portion 25B is directed to the tube 11 arranged on the lower side among the plurality of tubes 11 connected to the inlet header portion 22. As a result, the intake air flowing in the flow path expanding portion 23 can be reliably distributed to the lower tube 11.

次に、本実施形態に係るインタークーラ１による作用効果を説明する。 Next, the action and effect of the intercooler 1 according to the present embodiment will be described.

図３は、本実施形態に係るインタークーラ１の要部の吸気の流れを模式的に示す切り欠き斜視図である。なお、吸気の流れは破線で示してある。 FIG. 3 is a notched perspective view schematically showing the flow of intake air at a main part of the intercooler 1 according to the present embodiment. The flow of intake air is shown by a broken line.

本実施形態のインタークーラ１では、入口パイプ部２１から吸気が導入される流路拡大部２３の吸気下流端は、縦長の入口ヘッダー部２２に対して、該入口ヘッダー部２２の上端側から鉛直方向の中心位置近傍に亘って接続されている。このような流路構造において、本実施形態の下側整流プレート２５は、流路拡大部２３内に、その下流端部２５Ｂが入口ヘッダー部２２の下端側に向けて延びるように設けられている。すなわち、流路拡大部２３内を流れる吸気Ａ１〜Ａ３のうち、流路拡大部２３の下側内周面に沿って流れる吸気Ａ１が、下側整流プレート２５の板平面によって入口ヘッダー部２２の下端側に導かれ、下方のチューブ１１に効果的に導入されるように構成されている。これにより、吸気が流入しやすい上方のチューブ１１を含め、下方のチューブ１１に対しても吸気を確実に導くことができるようになり、上下方向に並列に配された各チューブ１１に対し、吸気を略均一に分配することが可能になる。 In the intercooler 1 of the present embodiment, the intake downstream end of the flow path expansion portion 23 into which the intake air is introduced from the inlet pipe portion 21 is vertical to the vertically long inlet header portion 22 from the upper end side of the inlet header portion 22. It is connected over the vicinity of the center position in the direction. In such a flow path structure, the lower rectifying plate 25 of the present embodiment is provided in the flow path expanding portion 23 so that its downstream end portion 25B extends toward the lower end side of the inlet header portion 22. .. That is, of the intake air A1 to A3 flowing in the flow path expansion portion 23, the intake air A1 flowing along the lower inner peripheral surface of the flow path expansion portion 23 is formed in the inlet header portion 22 by the plate plane of the lower rectifying plate 25. It is configured to be guided to the lower end side and effectively introduced into the lower tube 11. As a result, it becomes possible to reliably guide the intake air to the lower tube 11 including the upper tube 11 where the intake air easily flows in, and the intake air is taken to each tube 11 arranged in parallel in the vertical direction. Can be distributed almost uniformly.

また、吸気が下方のチューブ１１に対しても効果的に導入されることで、当該下方のチューブ１１内を流れる吸気の流速を効果的に上昇できるように構成されている。これにより、吸気の流速低下に伴うチューブ１１内の排水性悪化や排油性悪化を効果的に抑止することが可能になる。また、排油性悪化が抑止されることで、吸気系に還流されるブローバイガス等に含まれるオイルによってチューブ１１が閉塞することを防止できるようになる。 Further, by effectively introducing the intake air into the lower tube 11, the flow velocity of the intake air flowing in the lower tube 11 can be effectively increased. This makes it possible to effectively suppress the deterioration of drainage and oil drainage in the tube 11 due to the decrease in the flow velocity of the intake air. Further, by suppressing the deterioration of the oil drainage property, it becomes possible to prevent the tube 11 from being blocked by the oil contained in the blow-by gas or the like that is returned to the intake system.

さらに、流路拡大部２３内の下側整流プレート２５よりも上方に上側整流プレート２４を配置することにより、流路拡大部２３内を流れる吸気を、上側のチューブ１１に向かう吸気Ａ２と、中間に位置するチューブ１１に向かう吸気Ａ３とに分配できるように構成されている。これにより、上下方向に配列された各チューブ１１を流れる吸気の流速を均一にすることが可能になる。また、吸気の流速を均一にすることにより冷却効率の向上を図ることが可能になる。 Further, by arranging the upper rectifying plate 24 above the lower rectifying plate 25 in the flow path expanding portion 23, the intake air flowing in the flow path expanding portion 23 is intermediate with the intake air A2 toward the upper tube 11. It is configured so that it can be distributed to the intake air A3 toward the tube 11 located at. This makes it possible to make the flow velocity of the intake air flowing through the tubes 11 arranged in the vertical direction uniform. Further, it is possible to improve the cooling efficiency by making the flow velocity of the intake air uniform.
