Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle charging, and in particular to a unmanned aerial vehicle battery charging device with a heat dissipation structure. Background Art

[0002] Since the 21st century, the rapid development of civil drones has penetrated into all aspects of contemporary life. All walks of life are enjoying the huge benefits brought by the comprehensive application of drones. With the extensive use of drones at all levels of society, there are also various charging devices for drone batteries on the market, which greatly enhances the continuous operation capability of drones and brings real improvement in operation efficiency to users. However, the exponential growth of charging equipment has also brought a series of safety issues. Safety accidents caused by charging equipment failure are also common, making users' demand for the safety of drone charging equipment more urgent. Especially in recent years, a large number of drone battery batch charging devices have appeared on the market. Compared with traditional charging methods, batch charging devices can recharge a large number of different types of drones in a short time. However, the emergence of these high-power batch charging devices, although solving the battery life problem of a large number of batteries, also makes the huge heat generated by the long-term high-power operation of the charging equipment make the batteries and charging equipment easily damaged at high temperatures, seriously shortening the user's product life and increasing the user's procurement cost.

[0003] However, drone batteries will generate a lot of heat when charged in batches. Long-term operation of the charging equipment will cause overheating and damage to the battery and the internal equipment. The heat dissipation methods of drone charging equipment on the market are currently mainly ventilation heat dissipation and conventional fixed-power fan heat dissipation, which can only achieve air cooling by driving the gas flow through the fan. However, the air cooling effect of heat dissipation for the battery is not ideal, and the contact area between the battery and the gas is limited, and effective heat dissipation cannot be performed for local high-temperature locations. Therefore, in view of the above shortcomings, a drone battery charging device with a heat dissipation structure is proposed. Utility Model Content
