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 passage enlarged portion 23 is formed such that the passage area of the intake air increases from the intake inlet side toward the intake outlet side. Specifically, the flow passage enlarged portion 23 includes a first flow passage 23A that is connected to the inlet pipe portion 21 and extends in the vehicle longitudinal direction, and a first flow passage 23A that is connected to the side of the core portion 10 and extends in the vehicle width direction. 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 section 22 from the upper end side of the inlet header section 22 to near the center position in the longitudinal direction (vertical direction) from the vehicle width direction. Further, the connection position between the inlet pipe section 21 and the first flow path 23A is offset upward from the center position of the inlet header section 22 in the longitudinal direction (vertical direction). 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 air outlet section 30 includes a vertically elongated hollow outlet header section 32 attached to the outlet plate 14 of the core section 10, an outlet pipe section 31 connected to an intake pipe 42 on the engine side and extending in the longitudinal direction of the vehicle, and an outlet pipe.

FIG. 2 is a schematic perspective view partially cut away to show the main parts of the intercooler 1 according to the present embodiment.

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 (second rectifying plate of the present disclosure) is provided within the channel enlarged section 23, and is positioned at the inlet when viewed from above so as to follow the shape of the channel enlarged section 23. It is formed to curve from the pipe portion 21 side toward the side of 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 circumferential surface of the first flow path 23A while being spaced apart therefrom. Further, the downstream end 24B of the upper straightening plate 24 is located in the second flow path 23B above the center of the longitudinal direction (vertical direction) of the inlet header section 22, with its plate plane in the intake flow direction of the tube 11 (tube The tube 11 is provided at a predetermined clearance 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 enlarged channel section 23, and is aligned with the shape of the enlarged channel section 23 at the inlet when viewed from above. It is formed to curve from the pipe portion 21 side toward the side of 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 is located within the first flow path 23A below the upstream end 24A of the upper rectifying plate 24, and its plate plane is spaced from the lower inner circumferential surface of the first flow path 23A. However, they are provided so as to extend substantially parallel to each other. The downstream end 25B of the lower straightening plate 25 is placed in the second flow path 23B below the downstream end 24B of the upper straightening plate 24, with its plate plane (at least the lower surface) facing the lower end (lower side) of the inlet header section 22. ) is arranged at a predetermined clearance from the intake upstream end of the tube 11 so as to extend smoothly in a curved direction.

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 toward the lower tube 11 among the plurality of tubes 11 connected to the inlet header portion 22. Thereby, it becomes possible to reliably distribute the intake air flowing inside the flow path enlarged portion 23 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 effects of the intercooler 1 according to this embodiment will be explained.

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 cutaway perspective view schematically showing the flow of intake air in the main parts of the intercooler 1 according to the present embodiment. Note that 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 enlarged section 23 into which intake air is introduced from the inlet pipe section 21 is perpendicular to the elongated inlet header section 22 from the upper end side of the inlet header section 22. They are connected near the center position in the direction. In such a flow path structure, the lower rectifying plate 25 of this embodiment is provided in the flow path enlarged portion 23 so that its downstream end 25B extends toward the lower end side of the inlet header portion 22. . That is, among the intake air A1 to A3 flowing inside the enlarged flow path section 23, the intake air A1 flowing along the lower inner circumferential surface of the enlarged flow path section 23 is diverted from the inlet header section 22 by the flat surface 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. This makes it possible to reliably guide the intake air to the lower tubes 11 as well as the upper tubes 11 where intake air tends to flow in. 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 intake air into the lower tube 11, the flow rate of the intake air flowing inside the lower tube 11 can be effectively increased. This makes it possible to effectively prevent deterioration in drainage performance and oil drainage performance within the tube 11 due to a decrease in the flow rate of intake air. Moreover, by suppressing deterioration of oil drainage performance, it becomes possible to prevent the tube 11 from being blocked by oil contained in 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。 Furthermore, by arranging the upper rectifying plate 24 above the lower rectifying plate 25 in the expanded flow path section 23, the intake air flowing inside the expanded flow path section 23 is separated from the intake air A2 heading toward the upper tube 11, and The structure is such that the intake air can be distributed to the intake air A3 directed toward the tube 11 located at the center. This makes it possible to equalize the flow velocity of the intake air flowing through each tube 11 arranged in the vertical direction. Furthermore, by making the flow rate of intake air uniform, it is possible to improve cooling efficiency.
