Claims

[Claims for Utility Model Registration] 1. A liquid cooling jacket 2 is formed on at least a part of the cylinder head 1 of a partially liquid-cooled forced air-cooled engine E, and a radiator 3 is connected to the liquid cooling jacket 2 to supply a refrigerant liquid. A centrifugal cooling fan 4 is provided below, a radiator 3 is provided above, and an air guide case 5 is provided at the front in the front space of the engine E, and the cooling air generated by the cooling fan 4 is transferred to the air guide case 5. In a cooling system for a partially liquid-cooled forced air-cooled engine configured to guide the flow upward to the radiator 3 and backward to the cylinder 6, the flow split ratio is set inside the air guide case 6. A plate 7 is provided on the lower side of the radiator 3 and in front of the cylinder 6 in an upwardly inclined shape, and the ratio at which the cooling air generated by the cooling fan 5 is divided into the radiator 3 and the cylinder 6 is defined as the diversion ratio. A cooling device for a partially liquid-cooled forced air-cooled engine, characterized in that settings are configured using a setting plate 7. 2 Cylinder 6 of partially liquid-cooled forced air-cooled engine E
A temperature-sensitive actuator 8 is attached to the periphery of the diversion ratio setting plate 7, and when the temperature-sensitive actuator 8 responds to a low temperature, the slope of the setting plate 7 relative to the horizontal direction is changed. As the size increases, the temperature-sensitive actuator 8
The cooling device for a partially liquid-cooled forced air-cooled engine as claimed in claim 1, characterized in that the inclination of the setting plate 7 becomes smaller when the setting plate 7 responds to a high temperature.
