To provide a vehicular air conditioning unit in which a heat exchanger for cooling is arranged at an upstream side of an air blower, capable of uniformizing wind velocity distributions of air passing through the heat exchanger for cooling.SOLUTION: In a vehicular air conditioning unit 10, a heat exchanger 16 for cooling is arranged at an upstream side of an air blower 14 in an air conditioning case 12. The air blower 14 is arranged so that a suction port 145 opposes to the heat exchanger 16 for cooling. The heat exchanger 16 for cooling is arranged so that an opposing site 163 opposing to the suction port 145 is surrounded by non-opposing sites 164 that do not oppose to the suction port 145. In the air conditioning case 12, a plurality of air introduction ports 121 and 122 are formed at positions other than a projection area PA on which the opposing site 163 is projected. One air introduction port of the plurality of air introduction ports 121 and 122 is formed at the position opposite to a position at which at least the other air introduction port is formed, across the projection area PA.SELECTED DRAWING: Figure 1

    【課題】冷却用熱交換器が送風機の上流側に配置される車両用空調ユニットにおいて、冷却用熱交換器を通過する空気の風速分布の均一化を図る。【解決手段】車両用空調ユニット10は、空調ケース12における送風機14の上流側に冷却用熱交換器16が収容されている。送風機14は、吸込口145が冷却用熱交換器16と対向するように配置されている。冷却用熱交換器16は、吸込口145と対向する対向部位163が、吸込口145と対向しない非対向部位164によって囲まれるように配置されている。空調ケース12は、対向部位163を投影させた投影領域PAを避けた位置に複数の空気導入口121、122が形成されている。そして、複数の空気導入口121、122のうち一部の空気導入口が、他の空気導入口の少なくとも1つが形成された位置と投影領域PAを挟んで反対となる位置に形成されている。【選択図】図1
