To inhibit resonance of a fan shroud.SOLUTION: A blower module 10 includes: a cooling fan 14 configured to generate airflow to pass through a heat exchanger; and a fan shroud 12 which supports the cooling fan 14 and through which airflow generated by the cooling fan 14 passes. The fan shroud 12 includes: an air introduction part 20 which has a rectangular outer shape in a front view and into which airflow passing through the heat exchanger is introduced; a ring part 24 which has a circular outer shape in the front view and encloses the cooling fan 14 and from which airflow is led out; and a wind guide part 22 forming an air passage from the air introduction part 20 to the ring part 24. In the front view, a center MC of the ring part 24 is located offset from a center SC of the air introduction part 20 to the side toward one inner angle of the outer shape of the air introduction part 20. A protruding wall 36 is provided on a surface of the wind guide part 22 at a side opposite to the side to which the center MC of the ring part 24 is offset from the center SC of the air introduction part 20.SELECTED DRAWING: Figure 1

    【課題】ファンシュラウドの共鳴を抑制する。【解決手段】熱交換器を通過する気流を発生させる冷却ファン14と、冷却ファン14を支持すると共に冷却ファン14にて発生した気流が通過するファンシュラウド12とを備える送風装置10である。ファンシュラウド12は、正面視で外形が矩形状であり、熱交換器を通過する気流が導入される空気導入部20と、正面視で外形が円形状であり、冷却ファン14を取り囲んで気流が導出されるリング部24と、空気導入部20からリング部24への空気流路を形成する導風部22とを含む。正面視で空気導入部20の中心SCに対して、リング部24の中心MCは、空気導入部20の外形の1つの内角に向かった側にずれて位置しており、空気導入部20の中心SCに対して、リング部24の中心MCがずれている側とは反対側の導風部22の表面に突出壁36が設けられている。【選択図】図1
