Abstract
A vehicle cooling system comprises a vehicle unit, a heat exchanger, a cooling fan, a coolant pump, a three-way valve, and a control unit. The heat exchanger is arranged in the coolant route to selectively receive a coolant from the coolant outlet of the vehicle unit. The cooling fan is arranged to blow cooling air to the heat exchanger. The coolant pump is arranged to circulate the coolant through the coolant route. The three-way valve is arranged to switch the coolant route between a heat exchanger route that passes through the heat exchanger and a bypass route that bypasses the heat exchanger. The control unit is configured to control operation of at least one of the cooling fan, the three-way valve and the coolant pump based on a temperature of the coolant at the heat exchanger and a temperature of the coolant at the coolant outlet of the vehicle unit.
