内燃机的冷却控制装置及其冷却控制方法
摘要：
本发明涉及利用电动式泵使冷却水循环，并且利用电动风扇向散热器供给冷却风来进行内燃机的控制的冷却控制装置。该冷却控制装置具有在形成于内燃机的冷却介质通路中使冷却介质循环的电动式泵；对冷却介质进行冷却的散热器以及散热器风扇。内燃机在预热完成后停止时，驱动散热器风扇和电动式泵来冷却内燃机，在冷却介质的温度比内燃机停止时降低的情况下，以电动式泵动作的状态，使散热器风扇停止。
摘要（英）：

The present invention relates to a cooling control apparatus which performs control for cooling an internal combustion engine by causing an electric pump to circulate cooling water and causing an electric fan to supply cooling air to a radiator. The cooling control apparatus comprises an electric pump for circulating a coolant through a coolant passage formed in the internal combustion engine, and a radiator and a radiator fan which are for cooling the coolant. When the internal combustion engine stops after completion of warming-up, the radiator fan and the electric pump are driven to cool the internal combustion engine, and when a temperature of the coolant decreases to less than a temperature at a time of engine stop, the radiator fan is stopped in a state in which the electric pump is operated.
