Abstract:
A cooling apparatus cools a battery and a DC/DC converter. In a duct, a battery cooling fan having a great rated capacity is installed. The duct branches into a battery-side intake duct and a DC/DC converter-side intake duct on the downstream side of the battery cooling fan. In the battery-side intake duct, the battery is installed to received cooling air. In the DC/DC converter side intake duct, the DC/DC converter is installed to receive cooling air. A DC/DC converter cooling fan having a small rated capacity is installed directly upstream of the DC/DC converter. An ECU controls the two cooling fans based on the temperature of the battery and the DC/DC converter.
