Abrégé
(EN) Disclosed is a device for cooling an internal combustion engine in which circulation of cooling water is halted until the cooling water reaches a predetermined temperature, wherein decline in the durability of a radiator, which is caused by thermal strain that occurs when circulation of the cooling water is restarted and the cooling water is introduced into the radiator, is suppressed. An internal combustion engine (10) comprises an electric pump (23), a water temperature sensor (92), a radiator (21), and a thermostat (22). The water temperature sensor (92) detects a cooling water temperature (THW). The radiator (21) is capable of circulating the cooling water between the radiator (21) and an engine cooling system (13). If the cooling water temperature (THW) is equal to or greater than a valve opening temperature (TZ), the thermostat (22) opens and the cooling water is introduced into the radiator (21). An electronic control device (91) performs control in such a way that the discharge pressure of the cooling water is increased by the electric pump (23) before the thermostat (22) opens and cooling water is introduced into the radiator (21).
(ZH)

在直到冷却水的温度达到规定温度之前停止该冷却水的循环的内燃机冷却装置中,能够抑制因由于冷却水的循环停止被解除而冷却水流入热交换器时产生的热应变导致的散热器的耐久性降低。内燃机(10)具有电动泵(23)、检测冷却水温度(THW)的水温传感器(92)、能使冷却水在与内燃机冷却系统(13)间循环的散热器(21);当冷却水温度(THW)在开阀温度(TZ)以上时开阀而使冷却水流入散热器(21)的温度自动调节器(22)。电子控制装置(91)在使温度自动调节器(22)开阀而冷却水流入散热器(21)之前增大利用电动泵(23)排出冷却水的排出压力。
