To provide a vehicular cooling device capable of securing cooling performance in a radiator and a capacitor without causing an unnecessary increase in size of the capacitor even in a situation in which ambient temperature is relatively high.SOLUTION: A vehicular cooling device includes: a refrigeration cycle circuit 170 including a main capacitor 203 and a secondary capacitor 205; a cooling circuit 130 arranged on a vehicle rear side of the main capacitor and having a radiator 136 for cooling first working fluid for cooling an instrument 80 to be cooled, which is mounted on the vehicle, by the first working fluid cooled by the radiator; a capacitor control unit 800 for controlling cooling capacity in the main capacitor and the secondary capacitor; an ambient temperature detection unit 241; and an instrument-to-be-cooled temperature detection unit 243. When the ambient temperature and the temperature of the instrument to be cooled are a predetermined value or more, control is executed to make the cooling capacity in the secondary capacitor larger than the cooling capacity in the main capacitor.SELECTED DRAWING: Figure 2

    【課題】外気温が比較的高い状況下においても、コンデンサの不必要な大型化を招くことなく、ラジエータとコンデンサにおける冷却性能を確保することができる車両用冷却装置を提供する。【解決手段】主コンデンサ203および副コンデンサ205とを備えた冷凍サイクル回路170と、主コンデンサの車両後方側に配置され、第1作動流体を冷却するラジエータ136を備え、ラジエータにおいて冷却された第1作動流体により車両に搭載された冷却対象機器80を冷却する冷却回路130と、主コンデンサおよび副コンデンサにおける冷却容量を制御するコンデンサ制御部800と、外気温検知部241と、冷却対象機器温度検出部243とを含み、外気温度及び冷却対象機器の温度が所定値以上あった場合、副コンデンサにおける冷却容量が主コンデンサにおける冷却容量よりも大きくなるように制御する。【選択図】図2
