    Abstract: Processing circuitry of an in-vehicle cooling system regulates the flow rate of the coolant passing through a radiator, thereby regulating the coolant temperature to a target coolant temperature. The processing circuitry sets the target coolant temperature to a specified standard target coolant temperature when the engine is not operating in a specified temperature increase permitting range, and sets the target coolant temperature to a high target coolant temperature, which is higher than the standard target coolant temperature, when the engine is operating in the temperature increase permitting range. The processing circuitry changes the target coolant temperature in the temperature increase permitting range to a temperature lower than the high target coolant temperature and higher than or equal to the standard target coolant temperature, when the hydraulic oil temperature is higher than or equal to a specified temperature increase suppressing temperature.

  • Patent number: 10837346
    Abstract: A heat exchange module has a restriction protrusion that is provided to protrude between a blade of a cooling fan and a core portion of a heat exchanger and that restricts the blade from approaching the core portion more than a predetermined position. In a state where one side of an outline of a rectangular shaped fan shroud is disposed so as to face an installation surface, the restriction protrusion is provided in a position where the amount of water reaching the cooling fan through the heat exchanger becomes greater than the amount of water at position just below a rotation axis of the cooling fan in a case where at least a portion of the fan shroud is submerged in water.

  • Patent number: 10619554
    Abstract: A coolant circuit of an engine cooling apparatus includes a first passage where coolant flows through a radiator and a second passage where coolant flows without passing through the radiator. A coolant control valve controls a first passage flow rate Frad and a second passage flow rate Fsec. An outlet coolant temperature sensor detects an outlet coolant temperature Tout, which is a coolant temperature before a branching point of the first passage and the second passage. An inlet coolant temperature sensor detects an inlet coolant temperature Tin, which is a coolant temperature after a merging point of the first passage and the second passage. A coolant temperature estimator calculates a radiator coolant temperature Trad, which is a coolant temperature at a coolant exit of the radiator, when the first passage flow rate Frad is greater than or equal to a specified flow rate using equation (1).

  • Patent number: 10605150
    Abstract: The present invention provides a cooling device for an internal combustion engine of a vehicle. While the vehicle is in a decelerating state and while the internal combustion engine is in an idle reduction state, the cooling device increases the ratio of the cooling water circulation rate through a first path which extends through a heater core and a radiator while reducing the ratio of the cooling water circulation rate through a second path which bypasses the heater core and radiator. In addition, the cooling device increases the discharge flow rate of the electric water pump while the vehicle is in a decelerating state, and maintains the electric water pump in an operating state during idle reduction. Thus, the present invention allows accelerating the temperature decrease of the cylinder head during idle reduction, as well as improving fuel economy during acceleration when the vehicle is started.
