The invention relates to a cooling system (1), in particular for a drive motor (M) in an electric vehicle (F), comprising a cooling sleeve (2) having a longitudinal axis (3) and a heat-conducting structure (4), the cooling sleeve (2) surrounding the heat-conducting structure (4) in a region along the longitudinal axis (3), whereby a cooling channel (5) is formed between the cooling sleeve (2) and the heat-conducting structure (4), the heat-conducting structure (4) is configured and defined for housing, in a region, a first heat source (7), in particular a stator of the drive motor (M) for the electric vehicle (F). The heat-conducting structure (4) is configured for heat-conducting contact with a second heat source (8), in particular a power electronics for driving the electric machine (M) in the electric vehicle (F), which is arranged axially opposite the first heat source (7) along the longitudinal axis (3).
本发明涉及一种冷却系统(1),特别是用于电动车辆(F)中的驱动电机(M)的冷却系统,冷却系统具有带有纵轴线(3)的冷却套筒(2)和导热结构(4),冷却套筒(2)在沿纵轴线(3)在一个区域内包围导热结构(4),由此在冷却套筒(2)与导热结构(4)之间形成冷却通道(5),以便在冷却通道中引导冷却流体(6),导热结构(4)构造成并限定为用于在区域内容纳第一热源(7),对于电动车辆(F)来说第一热源特别是驱动电机(M)的定子。导热结构(4)构造成用于导热地接触第二热源(8),第二热源(8)特别是电动车辆(F)中的用于驱动电机(M)的电力电子器件,第二热源沿纵轴线(3)与第一热源(7)轴向地相对设置。
