<p>PROBLEM TO BE SOLVED: To enable to send water with pressure to engine cooling system and motor cooling system by one water pump by arranging engine cooling system and motor cooling system, and furnishing the engine cooling system with water pump and heat exchanger purposing heat dissipation of cooling water, and connecting the motor cooling system to the heat exchanger. SOLUTION: As a cooling device 10 of hybrid vehicle, such an engine cooling system 12 is provided that cooling water is supplied to engine side water jacket 16 by water pump 24 through cooling water supply channel 20, subsequently the water is conducted to radiator 18 through cooling water conducting channel 22 and discharges the heat, afterwards, the water is supplied again by the pump 24. Additionally, such a motor cooling system 14 is provided that cooling water is supplied to motor side water jacket 38 through cooling water supply channel 40 which is connected to the cooling water conducting channel 22, while thermostat valve 26 is installed on the downstream side of this connecting position, subsequently, the water is conducted to the radiator through cooling water conducting channel 42.</p> |
