COOLING DEVICE FOR VEHICLE APPARATUS

PROBLEM TO BE SOLVED: To improve cooling efficiency by guiding travel wind to a radiator for an apparatus on the traveling downstream side, in a case where a plurality of radiators are provided in an advancing direction of a vehicle.SOLUTION: A cooling device for cooling a first apparatus 3a and a second apparatus 3b, arranged in an advancing direction of a vehicle, with travel wind, comprises: a first radiator 5a projecting in a first direction (Y direction) perpendicular to the advancing direction and used for cooling the first apparatus 3a; a second radiator 5b arranged behind the first radiator 5a in the advancing direction, projecting in the first direction, and used for cooling a second apparatus 3b; protective covers 8a, 8b that cover the first radiator 5a and the second radiator 5b respectively; and a first wind guide 9a that guides travel wind to a space between the first radiator 5a and second radiator 5b from outside the protective covers 8a, 8b. The front end of the first wind guide 9a in the advancing direction juts out further in the first direction than the protective cover 8a, and guides travel wind flowing further outside in the first direction than the protective cover 8a covering the first radiator, in a direction in front of the second radiator 5b.SELECTED DRAWING: Figure 3 【課題】 車両の進行方向に複数の放熱器がある場合に、走行下流側の機器の放熱器に走行風を導くことで冷却の効率が向上させる。【解決手段】 車両の進行方向に並ぶ第１の機器３ａと第２の機器３ｂとを走行風で冷却する冷却装置であって、進行方向に垂直な第１方向（Ｙ方向）に突出して第１の機器３ａを冷却する第１の放熱器５ａと、第１の放熱器５ａより進行方向後方に離れて配置されて第１方向に突出して第２の機器３ｂを冷却する第２の放熱器５ｂと、第１の放熱器５ａと第２の放熱器５ｂとを覆う保護カバー８ａ、８ｂと、保護カバー８ａ、８ｂの外側から第１の放熱器５ａと第２の放熱器５ｂとの間に走行風を導く第１の風ガイド９ａと、を備え、第１の風ガイド９ａは、進行方向の前端が保護カバー８ａよりも第１方向に張り出し、第１の放熱器を覆う保護カバー８ａよりも第１方向外側を流れる走行風を第２の放熱器５ｂの前方に導く車両機器の冷却装置とした。【選択図】 図３
