摘要:
An electronic component housing structural body includes a first housing body accommodating electronic components and a second housing body accommodating electronic components. Fitting plane of the first and second housing bodies include a liquid passage area and a communicating passage area. The liquid passage area includes a cooling passage in which cooling liquid flows. The communicating passage area includes a communicating passage that connects housing chambers of the first and second housing bodies. Furthermore, a single sealing member is disposed on the fitting plane to independently surround and seal the liquid passage area and the communicating passage area.

A cooling apparatus cools a battery and a DC/DC converter. In a duct, a battery cooling fan having a great rated capacity is installed. The duct branches into a battery-side intake duct and a DC/DC converter-side intake duct on the downstream side of the battery cooling fan. In the battery-side intake duct, the battery is installed to received cooling air. In the DC/DC converter side intake duct, the DC/DC converter is installed to receive cooling air. A DC/DC converter cooling fan having a small rated capacity is installed directly upstream of the DC/DC converter. An ECU controls the two cooling fans based on the temperature of the battery and the DC/DC converter.
摘要:
In the vehicle of the invention, when the temperature of an inverter 42 for driving a motor MG2 linked to front wheels 62a and 62b reaches or exceeds a preset restriction start temperature, the drive control of the invention controls the inverters 42 and 43 to gradually decrease the output torque of the motor MG2 simultaneously with a gradual increase in output torque of a motor MG3, which is linked to rear wheels 64a and 64b. Such torque control ensures output of a torque demand required for the vehicle. When the temperature of the inverter 42 reaches or exceeds a preset frequency switchover temperature, which is higher than the restriction start temperature, the drive control of the invention controls the inverters 42 and 43 to lower a switching frequency of transistors T1 to T6 in the inverter 42 and to ensure output of the torque demand. Such drive control effectively relieves the load of the inverter 42, while decreasing the frequency of lowering the switching frequency of the inverter 42. This arrangement thus desirably attains both prevention of overheat of the inverter 42 and reduces the switching noise.

摘要:
An inverter unit for vehicle (20) is formed in such a manner that a capacitor module (40) is stacked on the upper portions of a main inverter circuit module (32) and a sub inverter circuit module (34) so as to connect the corresponding external terminals by a bolt (66). Here, by matching a positive electrode terminal (44) and a negative electrode terminal (46) of the capacitor module (40) with a positive side electrode terminal (45) and a negative side electrode terminal (47) of the main inverter circuit module (32), and at the same time by matching a positive electrode terminal (48) and a negative electrode terminal (50) of the capacitor module (40) with a positive side electrode terminal (49) and a negative side electrode terminal (51) of the sub inverter circuit module (34), responsible terminals are connected with this bolt (66) each other.
