Abstract
A pressure relief valve is opened from a first time to a second time for the purpose of reducing the pressure in the gas phase in a gas-liquid separator. A first water pump (WP) is driven at a third time and a fourth time. The third time and fourth time correspond to timings at which a difference between a boiling temperature and an actual temperature becomes equal to or greater than a predetermined temperature. Since liquid-phase coolant in a catch tank can be fed to another water pump by driving the first WP, the actual temperature of the liquid-phase coolant immediately upstream of the other water pump can be lowered. It is thus possible to prevent intense boiling of the liquid-phase coolant immediately upstream of the other water pump.
