Claims

[Scope of utility model registration request]

An upper cooling water passage connecting a cooling water outlet of the engine and a cooling water inlet formed at the upper part of the radiator, and a cooling water outlet formed at the lower part of the radiator and a water passage provided at a position below the cooling water outlet of the engine. A lower cooling water passage connects the pump inlet, a bypass cooling water passage connects the upper cooling water passage and the lower cooling water passage by bypassing the radiator, and a bypass cooling water passage connects the engine cooling water to the radiator by sensing the cooling water temperature. In an internal combustion engine cooling device equipped with a temperature-sensitive flow control valve that variably controls a flow rate ratio to a cooling water passage, the cooling water bypasses a temperature-sensing section that senses the engine cooling water temperature of the temperature-sensitive flow control valve. A valve body is provided in the lower cooling water passage at the confluence with the passage outlet or downstream thereof, and is capable of variable control of the opening ratio of the cooling water passage that guides the engine cooling water to the radiator and the bypass cooling water passage. A valve body driving means provided at a branch point of the upper cooling water passage with the bypass cooling water passage inlet or downstream thereof, and driving the valve body according to the cooling water temperature sensed by the temperature sensing part. A cooling device for an internal combustion engine, characterized in that it is configured by providing the following.
