The EDS (50) has a motor housing (70) and an inverter housing (90). The inverter housing (90) has inverter fins (92). The motor housing (70) has a motor fin (72) and a motor guide plate (77). The motor fins (72) and the motor guide plate (77) are provided on the outer peripheral surface (70a). The motor guide plate (77) is parallel to the motor fins (72) along the outer peripheral surface (70a). The motor guide plate (77) guides the air conveyed by the blower fan (111) in the circumferential direction (CD) such that the air flows toward the motor fins (72) and the inverter fins (92). The motor guide plate (77) is convexly curved so as to protrude toward the upstream side in the axial direction (AD).
EDS(50)具有电动机外壳(70)和逆变器外壳(90)。逆变器外壳(90)具有逆变器翅片(92)。电动机外壳(70)具有电动机翅片(72)和电动机引导板(77)。电动机翅片(72)和电动机引导板(77)设置于外周面(70a)。电动机引导板(77)沿着外周面(70a)并与电动机翅片(72)并列。电动机引导板(77)以使由送风风扇(111)输送来的空气朝向电动机翅片(72)和逆变器翅片(92)流动的方式在周向(CD)上进行引导。电动机引导板(77)以朝向轴向(AD)的上游侧隆起的方式凸状地弯曲。
