Claims

[Scope of utility model registration request]

j7. A liquid path formed in the internal combustion engine, a coolant supply path for supplying coolant to the liquid path, a pump interposed in the coolant supply path, and circulating the coolant from the liquid path.j7. A coolant return path, a main thermostat interposed in the coolant return path, an intake pipe heating path branched from the liquid path and heating the intake pipe, and interposed between the coolant return path and the coolant supply path. radiator, a bypass path that branches from the coolant supply path before the pump and connects to the coolant return path before the main thermostat, and a sub-thermostat interposed in the bypass path. A cooling device for an internal combustion engine, characterized in that it communicates with a bypass path.
