Automotive internal combustion engine cooling system

An automotive internal combustion engine cooling system in which cooling water for a water-cooled internal combustion engine is designed to be circulated by means of a pump, the automotive internal combustion engine cooling system comprising;

• a cooling water circuit in which cooling water circulates in a radiator adapted to cool cooling water from the internal combustion engine,
• a hot water circuit in which hot water circulates in a heater core adapted to heat air to be let out into a passenger compartment using hot water from the internal combustion engine as a heat source,
• an air mixing door for adjusting the volume of air which passes through the heater core,
• a heat storage element bypass passage for passing hot water into the heater core from the hot water circuit,
• a heat storage element installed in the heat storage element bypass passage for storing hot water supplied from the internal combustion engine,
• a flow path selector valve for adjusting the distribution of hot water to the heat storage element and the heater core, and
• a control unit for controlling the operation of the air mixing door and the flow path selector valve, wherein
• the control unit controls the flow path selector valve such that the flow rate of hot water to be distributed to the heater core is increased as the volume of air passing through the heater core increases.
