Abstract
A powertrain includes: a motor control unit (1) including a housing (11) and a first functional unit (12) disposed in the housing (11) and capable of generating heat during operation; and a heat exchanger (2) disposed in the housing (11), where the heat exchanger (2) includes a first circulation channel (21) for a first cooling medium to circulate and a second circulation channel (22) for a second cooling medium to circulate. The first circulation channel (21) has a first external cooling surface (P1), and the first circulation channel (21) conducts heat with the first functional unit (12) at the first external cooling surface (P1); and/or the first circulation channel (21) has a second external cooling surface (P2), and the first circulation channel (21) conducts heat with an inner surface of the housing (11) at the second external cooling surface (P2).
