Abstract: A heat dissipation apparatus and a photovoltaic inverter are related to the field of heat dissipation device technologies, to improve a heat dissipation capability of the heat dissipation apparatus. The heat dissipation apparatus includes at least two stacked fan layers, and each fan layer includes at least one fan. A heat dissipation channel in a radiator has a first inlet, and the first inlet communicates with each air exhaust vent in at least one fan layer by using an air duct component. Compared with a solution in which fans are arranged along a width direction of the radiator, the at least two fan layers are stacked, which may not be limited by a width of the radiator. More fans can be arranged in a hierarchical stacking manner, and more fans can increase an overall amount of exhausted air, thereby improving the heat dissipation capability of the heat dissipation apparatus.

Abstract: A motor, a powertrain, and a device. A plurality of first oil channels are formed between an inner surface of a housing and an outer surface of a stator core, second oil channels are formed at groove roots of coil slots of the stator core, to form double-layer oil channels at the outer surface of the stator core and the root of the coil slot of the stator core, and ensure effective cooling of the stator core and a coil winding. After cooling oil is injected from an oil filling port, a flow direction of the cooling oil in some of the second oil channels is opposite to that of cooling oil in a remaining second oil channel, so that interleaved reverse flows are implemented, and axial temperature of the stator core and the coil winding is more even.
