Cooling system for hybrid vehicle

A cooling system for a hybrid vehicle where a high-power unit is mounted, the cooling system comprising:

• a first cooling system structured to cool the high-power unit with a first coolant;
• wherein the first cooling system includes:
• a main passage structured to allow the first coolant to circulate through the main passage;
• a radiator structured to perform heat exchange with the first coolant;
• a cooler structured to cool supercharged intake air supplied to an internal combustion engine mounted on the hybrid vehicle;
• a bypass passage connected to the main passage so as to bypass the radiator;
• and a bypass valve structured to control a flow rate of the first coolant flowing through the bypass passage;
• wherein the cooler is located downstream of the high-power unit and upstream of the radiator in a direction of flow of the first coolant;
• and
• wherein the bypass valve is structured to be controlled to prevent the first coolant from flowing to the radiator, in response to a condition that the first coolant has a temperature lower than a first predetermined value.
