To provide a cooling duct capable of efficiently introducing traveling wind into a heat exchanger while reducing manufacturing costs.SOLUTION: A cooling duct 10 introduces traveling wind into heat exchangers (3A, 3B, and 4) attached to a radiator support 1 at a front part of a vehicle through a left side bracket 7 and a right side bracket 8, and is equipped with a rear duct 40 that introduces the traveling wind passing through a front upper duct 20 and a front lower duct 30 into the heat exchangers (3A, 3B, and 4). A rear portion of a left side wall portion 48 of the rear duct 40 is oppositely disposed to a front portion of a left side bracket 7 and a rear portion of a right side wall portion 49 of the rear duct 40 is oppositely disposed to a front portion of a right side bracket 8 so as to form labyrinth seals 11 and 12 respectively.SELECTED DRAWING: Figure 5

    【課題】製造コストの低減を図りながら、熱交換器に走行風を効率良く導入可能な冷却ダクトの提供。【解決手段】冷却ダクト10は、車両の前部のラジエータサポート1に左サイドブラケット7および右サイドブラケット8を介して取り付けられる熱交換器(3A,3B,4)に走行風を導くものであって、フロントアッパーダクト20およびフロントロアダクト30を通過した走行風を熱交換器(3A,3B,4)に導くリアダクト40を備える。リアダクト40の左側壁部48の後部が左サイドブラケット7の前部に、また、リアダクト40の右側壁部49の後部が右サイドブラケット8の前部に、ラビリンスシール11,12を作るように対向配置されている。【選択図】図5
