  • Publication number: 20230311638
    Abstract: A cooling system for an electric vehicle is provided, which includes a drive unit disposed in a front part of a vehicle, a charger disposed rearward of the drive unit, a coolant circuit connected to the drive unit and the charger and having a bypass route bypassing the charger, a pump, a heat exchanger, at least one temperature sensor, and a control device which controls circulation of the coolant to the coolant circuit based on the temperature of the drive unit. The control device sends the coolant to the bypass route, when the charger is not in operation, and when the temperature of the drive unit is below a given temperature, and sends the coolant to the drive unit after sending the coolant to the charger, when the charger is not in operation, and when the temperature of the drive unit is above the given temperature.

  • Patent number: 11446984
    Abstract: A cooling system is provided to cool fluid used in a device mounted on a vehicle, by exchanging heat with cooler cooling water in a cooler. The system includes a cooling water passage connected to the cooler and having an undercover cooling water passage provided to an undercover, a cooler radiator configured to cool the cooler cooling water by exchanging heat between the cooler cooling water and air flowing into an engine bay from a grille, a flow rate adjuster configured to adjust a flow rate of the cooler cooling water supplied the undercover cooling water passage, and a controller configured to acquire at least a pressure or a temperature of the fluid, and control the flow rate adjuster to increase the flow rate of the cooler cooling water supplied to the undercover cooling water passage based on an increase in the pressure or the temperature of the fluid.

  • Patent number: 11346272
    Abstract: A cooling system is provided to cool an engine of a vehicle, which includes a cooling water passage through which cooling water is supplied to a water jacket formed in the engine, and having an undercover cooling water passage provided in an undercover, a radiator provided in the cooling water passage and configured to cool the cooling water by exchanging heat with air flowing into an engine bay from a grille, a flow rate adjuster configured to adjust a cooling water flow rate supplied to the undercover cooling water passage, and a controller configured to acquire a temperature of the cooling water of the water jacket in the engine and, when the temperature is above a temperature threshold, control the flow rate adjuster to increase the flow rate of the cooling water supplied to the undercover cooling water passage compared to when the acquired temperature is below the temperature threshold.

  • Patent number: 11346271
    Abstract: A cooling system configured to cool an engine of a vehicle is provided, which includes a cooling water passage through which cooling water is supplied to a water jacket in the engine, and having an undercover cooling water passage provided in an undercover and where the cooling water is cooled by exchanging heat with air below the undercover, a radiator provided in the cooling water passage and configured to cool the cooling water by exchanging heat with air flowing into an engine bay from a grille, a flow rate adjuster, a grille shutter provided to the grille and configured to change an effective opening area of the grille, and a controller configured to determine abnormality of the grille shutter and control, when determined as abnormal, the flow rate adjuster to increase the flow rate of the cooling water supplied to the undercover cooling water passage.
