PROBLEM TO BE SOLVED: To improve the take-in efficiency of a traveling wind to an air introduction duct without installing a special member and enlarging the air introduction duct, in an intercooler in which the duct is also opened upwardly.SOLUTION: An air introduction duct 5 has an inner frame 9 which is vertically opened, and a rear wall 10 taking a forward inclination posture is integrally formed at a rear part of the inner frame 9. Groups of wind warpage grooves 24 for upwardly raising traveling winds are formed at a side deck part 22 arranged at a single side of the inner frame 9 in multiple stages in fore-and-aft directions. The traveling wind flowing in the side deck part 22 is raised upwardly, and an air curtain is formed in a point of the side deck part 23. It is thereby avoided that the traveling wind escapes from the air introduction duct 5, and the cooling efficiency of an intercooler can be improved.SELECTED DRAWING: Figure 1

    【課題】ダクトを上向きにも開口させているインタークーラにおいて、特別の部材を設けたり導風ダクトを大型化したりすることなく、導風ダクトへの走行風の取り込み効率を向上させる。【解決手段】導風ダクト5は、上下に開口したインナーフレーム9を有しており、インナーフレーム9の後部に、前傾姿勢の後ろ壁10を一体に形成している。インナーフレーム9の片側に設けたサイドデッキ部22に、走行風を上向きに巻き上げる風向反らせ溝24の群が前後多段に形成されている。サイドデッキ部22を流れる走行風が上向きに巻き上げられて、サイドデッキ部23の箇所にエアカーテンが形成される。このため、導風ダクト5から走行風が逃げ出ることを抑制して、インタークーラの冷却効率を向上できる。【選択図】図1
