1. A vehicle cooling device, comprising:
- a heat exchanger which cools coolant by a cooling wind;
a first cooling fan and a second cooling fan which are respectively disposed along a vehicle front-rear direction with respect to the heat exchanger and which are capable to be rotated and driven respectively by different driving units, the first cooling fan being capable to guide an air at a vehicle front side to a vehicle rear side as the cooling wind by being rotated and driven, and the second cooling fan being disposed at a vehicle front side of the first cooling fan;
a first fan shroud enclosing a periphery of the first cooling fan;
a second fan shroud enclosing a periphery of the second cooling fan;
a first ventilating unit formed at the first fan shroud, and impeding passage of the cooling wind through the first fan shroud when the first cooling fan is driven, and allowing passage of cooling wind through the first fan shroud when the second cooling fan is driven; and
a second ventilating unit formed at the second fan shroud, and impeding passage of the cooling wind through the second fan shroud when the second cooling fan is driven, and allowing passage of the cooling wind through the second fan shroud when the first cooling fan is driven.

Abstract
A cooling device for a vehicle is provided at a vehicle comprising an engine control unit which stops an engine due to establishment of engine stoppage conditions and restarts the engine due to establishment of engine restart conditions. The cooling device for a vehicle is able to cool a coolant within a heat exchanger for cooling by cooling wind, which is guided from an exterior of the vehicle, passing through the heat exchanger for cooling. Cooling by driving force of either one of an electric motor or the engine can be selected in accordance with preset conditions.
