たことを特徴とする内燃機関の冷却装置。 An internal combustion engine comprising a water jacket on the cylinder head side and a water jacket on the cylinder block side, which are configured to be kept at different temperatures independently of each other, and are provided with a heater system that uses high temperature liquid phase refrigerant in the water jacket as a heat source. In a cooling device, a main refrigerant outlet and a main refrigerant return port for the heater are formed on either the cylinder head side water jacket or the cylinder block side water jacket, and a sub-refrigerant outlet or an auxiliary refrigerant return port, an on-off valve disposed between the water jacket on the cylinder head side and the water jacket on the cylinder block side and communicating the two at low temperatures, and disposed in the heater outlet passage or the heater inlet passage; Forms a flow path from the main refrigerant outlet to the main refrigerant return port at high temperatures, and a flow path from the main refrigerant outlet to the auxiliary refrigerant return port or from the auxiliary refrigerant outlet to the main refrigerant return port at low temperatures. 1. A cooling device for an internal combustion engine, comprising: a flow path switching mechanism that forms a flow path switching mechanism.
