The invention discloses a cooling device, a hybrid power system and a vehicle, the cooling device is suitable for cooling a generator and/or a driving motor, the cooling device comprises a first driving structure, a second driving structure, an oil source and a heat exchange structure, and the oil source communicates with the inlet side of the heat exchange structure; wherein the outlet side of the heat exchange structure is configured to be connected with the generator and then connected with an oil source, and the cooling device has a first heat exchange state that the first driving structure drives an oil source side medium to pass through the heat exchange structure and the generator and then circulates back to the oil source so as to cool and lubricate the generator; the outlet side of the heat exchange structure is further configured to be connected with a driving motor and then connected with an oil source. And the cooling device has a second heat exchange state in which the second driving structure drives the oil source side medium to circulate back to the oil source after passing through the heat exchange structure and the driving motor so as to cool and lubricate the driving motor. The cooling device with the structure meets the requirements of motor cooling and lubrication under different working conditions, improves the efficiency and reliability of the whole system, and greatly reduces the cost.

    本发明公开了一种冷却装置冷却装置、混合动力系统及车辆,冷却装置适于对发电机和/或驱动电机冷却,包括:第一驱动结构、第二驱动结构、油源以及换热结构,油源与换热结构的进口侧连通;其中,换热结构的出口侧被配置为与发电机相连后与油源相连,冷却装置具有第一驱动结构驱动油源侧介质经由换热结构和发电机后循环回油源以对发电机冷却润滑的第一换热状态;换热结构的出口侧还配置为与驱动电机相连后与油源连接;冷却装置具有第二驱动结构驱动油源侧介质经由换热结构和驱动电机后循环回油源以对驱动电机冷却润滑的第二换热状态。此结构的冷却装置,满足适应不同工况下的电机冷却润滑需求,提高整个系统的效率和可靠性、成本大幅降低。
