Description

Technical Field

[0001] This utility model relates to the field of charging technology, and in particular to a high-power charging power supply. Background Technology

[0002] A rechargeable battery is a type of battery with a limited number of recharge cycles, used in conjunction with a charger. The advantages of rechargeable batteries are that they are economical, environmentally friendly, have ample capacity, and are suitable for high-powered or long-duration electronic devices, such as portable music players, electric toys, and electric vehicles. Currently, the most common rechargeable batteries on the market are nickel-cadmium (NiCd), nickel-metal hydride (NiMH), lithium-ion, lead-acid (lead-acid), and lithium iron phosphate (LFP) batteries.

[0003] To improve battery charging speed, most manufacturers have developed corresponding high-power charging power supplies for charging rechargeable batteries. This significantly shortens charging time and facilitates the widespread application of large-capacity rechargeable batteries. However, the excessive charging current of high-power charging power supplies generates a large amount of heat during continuous charging, which is difficult to dissipate. This leads to excessively high internal temperatures, causing electronic components to operate at high temperatures for extended periods, thus shortening their lifespan. Therefore, it is necessary to improve existing high-power charging power supplies. Utility Model Content

When the cooling fan inside the appliance is activated, this design can slow down the time it takes for the airflow generated by the cooling fan to pass through, thereby extending the heat exchange time and improving the heat dissipation effect.

[0009] As a preferred embodiment, each of the multiple heat dissipation fins is provided with reinforcing ribs to enhance the strength of the heat dissipation fins.

[0010] As a preferred embodiment, the side of the housing is provided with a recess for embedding the display screen, and multiple indicator light holes are provided on the side of the recess.
