Title:
CHARGER
Document Type and Number:
WIPO Patent Application WO/2022/095213
Kind Code:
A1
Abstract:
A charger, comprising a box body (10), an engine (20), a generator (30), and a power management assembly (40), the box body (10) having an air outlet (101), and the engine (20), the generator (30), and the power management assembly (40) being disposed in the interior of the box body (10). The engine (20) comprises an output shaft (21), the generator (30) comprises a rotor (31) and an impeller (32) mounted to the rotor (31), the rotor (31) is connected to the output shaft (21), and the power management assembly (40) is electrically connected to the generator (30), the power management assembly (40) being opposite to the impeller (32), such that the airflow generated by the rotation of the impeller (32) is blown toward the power management assembly (40) so as to carry away heat generated by the power management assembly (40). In the charger, by providing the power management assembly (40) opposite to the impeller (32), the airflow generated by the rotation of the impeller (32) is blown toward the power management assembly (40) and carries away the heat generated by the power management assembly (40), which can achieve a better heat dissipation effect for the power management assembly (40), and improve the reliability of the charger, and thus simplifying the heat dissipation structure by utilizing the airflow generated by the rotation of the impeller (32) of the generator (30).
