A cooling device which can arrange a cooling water tank in parallel near an electric power control device, and can more effectively utilize a space inside the engine room, and by which the miniaturization of the engine room is realized, and temperature increase of the wiring can be suppressed. The cooling device is a cooling device for cooling a device of a vehicle including an electric power control device to control an input-output voltage of the vehicle and a wiring connected to the electric power control device, and includes cooling water for cooling the device of the vehicle and a cooling water tank for accommodating the cooling water; the cooling water tank has a dented side surface wall along an external shape of the wiring, and has a shape which covers at least a portion of the wiring by closely disposing the wiring along the dented side surface wall.

Vehicle electric power control cooling device mounting

A hybrid vehicle is provided in which, since the driving force of a generator/motor (M) disposed so as to surround the outer periphery of an input shaft () of a transmission (T) is transmitted to an output shaft () of the transmission (T) via an endless chain (), it is possible to carry out the so-called leg shaft drive, in which transmission of the driving force between the generator/motor (M) and the output shaft () is carried out without going through an engine (E) and the input shaft (), thus reducing power consumption and enhancing energy recovery efficiency during regenerative braking. Furthermore, since a crankshaft () of the engine (E) and the input shaft () of the transmission (T) are disposed coaxially, and the generator/motor (M) is disposed at a position sandwiched between the engine (E) and the transmission (T), it is possible to employ the same layout for the generator/motor (M) as for a conventional sandwiched generator/motor, and the leg shaft drive system can be employed without greatly modifying the design of the transmission (T).

Hybrid vehicle

In order to appropriately control the temperature state of multiple equipment having differing management temperatures, while preventing complication of the apparatus structure, a cooling apparatus for a hybrid vehicle is provided with a seventh flow pathwhich flows coolant which has flowed only through a main flow pathof a radiatorto a water jacketvia a first thermostatwhich has an induction temperature set relatively high; an eighth flow pathwhich flows coolant which has flowed through the main flow pathand a sub flow pathof the radiatorto the water jacketvia a second thermostatwhich has an induction temperature set relatively low, and also supplies the coolant to a PDUand a downverter; and a bypass flow pathwhich connects a fifth flow pathwhich supplies coolant discharged from the water jacketto the radiator, and a position of the eighth flow pathon a downstream side of the second thermostat
