To improve cooling performance.SOLUTION: A cooling unit comprises: a cooling core which has a front face facing an upstream side in a ventilation direction and a back face facing a downstream side in the ventilation direction and through which air passes from the front face to the back face; a shroud which covers the back face so that a downstream side space is formed at the back face side of the cooling core and in which a plurality of openings that makes the downstream side space communicate with the downstream side are formed; a plurality of drive fans which are provided corresponding to the respective openings, and send air in the downstream side space further to the downstream side by rotating around a central axis line extending in the ventilation direction. The central axis line is inclined with respect to the ventilation direction, and an extending direction of the central axis line of each drive fan are different from each other.SELECTED DRAWING: Figure 3

    【課題】冷却性能を向上させる。【解決手段】通風方向の上流側を向く前面、及び、通風方向の下流側を向く背面を有し、前面から背面に空気が通過するクーリングコアと、クーリングコアの背面側に下流側空間が形成されるように背面を覆うとともに、下流側空間を下流側に連通させる複数の開口部が形成されたシュラウドと、各開口部に対応して複数が設けられて、通風方向に延びる中心軸線回りに回転することで下流側空間内の空気をさらに下流側に送風する駆動ファンと、を備え、中心軸線は通風方向に対して傾斜しているとともに、各駆動ファンの中心軸線の延在方向が互いに異なる。【選択図】図3
