To provide a vehicle cooling device which suppresses excessive cooling of an air suction gas containing an EGR gas, that circulates in an intercooler in an engine with supercharger and intercooler, and can suppress generation of condensed water.SOLUTION: The vehicle cooling device comprises: an engine 4 having an EGR device 14, a supercharger 10, and an intercooler 12 for cooling an air suction gas; a cooling water flow channel 32 in which cooling water for cooling motor drive devices 6, 16, 18 flows; and a cooling water flow rate regulator 48. The cooling water flow channel 32 has: a first flow channel 32a in which first cooling water for cooling high voltage components 16, 18 of the motor drive device flows; and a second flow channel 32b, which branches from the first flow channel and in which second cooling water for cooling the intercooler flows. The cooling water flow rate regulator is provided in the second flow channel of the cooling water flow channel, and can regulate a flow rate of the second cooling water.SELECTED DRAWING: Figure 2
