| 摘要 |
<p>The present invention relates to a thermal management device for a vehicle drive train made of at least one traction battery (10) and electric traction members (17, 18, 19), comprising a radiator (14), a coolant/water evaporator (11), and a first cooling circuit for cooling the battery (10), through which circuit a coolant flows. The device is characterized in that the radiator (14) has at least two outlets, a first outlet of the radiator (14) allowing a single pass through the radiator (14) of the coolant bound for the electric members (17, 18, 19) of the electric drive train, and a second outlet of the radiator allowing at least two passes through the radiator of the coolant headed for the battery (10), the radiator (14) being able to define a second cooling circuit for the electric members (17, 18, 19) of the electric drive train which is independent of the first cooling circuit for the traction battery (10).</p> |
