Abstract: Embodiments of this application provide a magnetic element and an electronic device. The magnetic element is used in an electronic device. The magnetic element includes a composite magnetic core and a winding. The composite magnetic core includes an external magnetic shell and an internal magnet. The internal magnet is formed by a wound strip material. The external magnetic shell partially or entirely covers a periphery of the internal magnet. The external magnetic shell is fixedly connected to the internal magnet. The winding is on an outer surface of the external magnetic shell. The external magnetic shell is configured to protect the internal magnet from pulling force in a winding process of the winding. The external magnetic shell is configured to increase common-mode impedance of the magnetic element and improve a filtering effect of the magnetic element.

Abstract: A direct current contactor includes a case and two groups of contact components disposed in the case. Each group of contact components includes two moving contacts connected to each other and two fixed contacts. The direct current contactor further includes a drive system configured to drive the moving contacts to move in a direction close to or away from the fixed contacts, so that the moving contacts are connected to or disconnected from the fixed contacts. The case has an arc-extinguishing cavity. A first baffle in the arc-extinguishing cavity divides the arc-extinguishing cavity into a first arc-extinguishing chamber and a second arc-extinguishing chamber. The contact components are respectively located in the first arc-extinguishing chamber and the second arc-extinguishing chamber. In other words, the two groups of contact components are integrated into two arc-extinguishing chambers of one arc-extinguishing cavity and perform connection/disconnection drive by using a single drive system.

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.
