摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of knocking due to a rise in coolant temperature, and suppress energy loss, a change in water temperature and noise due to drive of a fan.SOLUTION: A cooling apparatus for an internal combustion engine includes: a fan that cools a coolant by operating at least at a first drive voltage and a second drive voltage higher than the first drive voltage; and a control unit that drives the fan at the first drive voltage when a vehicle is driven at a low vehicle speed lower than a vehicle speed threshold and a coolant temperature is higher than a fan low-voltage activation threshold. The fan is driven at a low voltage under such conditions that the fan is less subject to aerodynamic drag, thereby preventing knocking from occurring due to the rise in coolant temperature, also reducing power consumption, and suppressing the change in water temperature and noise.
