Description

Technical Field

[0001] The utility model relates to a heat dissipation type power supply structure, belonging to the technical field of power supplies. Background Art

[0002] The charging power supply is a rectifier device for charging batteries. In the early days, AC motor-DC generator sets were used as charging power supplies. After the 1960s, they were replaced by charging power supplies composed of power electronic devices. The charging power supply often uses a single-phase or three-phase half-controlled rectifier circuit (composed of a mixture of thyristors and diodes, and the load voltage cannot be reversed) or an uncontrolled rectifier circuit (composed of a rectifier diode without controlled kinetic energy) connected to the rectifier circuit of the AC voltage regulator. In the DC circuit, a smoothing reactor is required to suppress the pulsation of the DC current and prevent the current from being discontinuous.

[0003] In order to speed up the charging efficiency, the existing charging power supply often charges the battery with a large current. During the high-current charging process, a large amount of heat is inevitably generated. If the heat cannot be dissipated in time, it will cause damage to the circuit board, thereby causing the charging power supply to fail to work normally. In order to improve the heat dissipation effect, while increasing the fan power, the fan's air inlet also needs to be enlarged, which causes serious dust accumulation at the air outlet. When maintaining the fan, the existing power supply structure cannot clean the partition at the air outlet at the same time, and needs to be improved. Utility Model Content
