The invention discloses an efficient heat dissipation plant protection unmanned aerial vehicle which comprises a vehicle body, a pesticide box, a motor and a nozzle, the pesticide box is cylindrical, penetrates through the vehicle body and is arranged in the center of the vehicle body, the motor is installed on a vehicle arm of the vehicle body, the nozzle is arranged below the motor and is connected with the pesticide box, and the efficient heat dissipation plant protection unmanned aerial vehicle further comprises a cooling box loaded with a cooling medium. The cold box is of an annular structure, the bottom face of the cold box makes contact with the upper surface of the machine body, an annular containing space is formed between the inner circumferential wall of the cold box and the side wall of the medicine box, a plurality of communicating holes are formed in the bottom of the inner circumferential wall of the cold box and communicate with an inner cavity of the medicine box through communicating pipes, and electric control valves are arranged on the communicating pipes. The electric control valve is opened to enable a cooling medium in the cold box to flow into the medicine box to be mixed with medicine liquid deposited at the bottom of the medicine box. Through the design of the cold box, the problem of low heat dissipation efficiency of the motor is effectively solved, liquid medicine deposition is prevented through mixing of a cooling medium and the liquid medicine, and the pesticide utilization rate and the spraying uniformity are improved.
本发明公开了一种高效散热的植保无人机,包括机体、药箱、电机和喷头,药箱为圆柱状,穿过机体并设置于机体的中心,电机安装于机体的机臂上,喷头设置于电机的下方并与药箱连接,还包括一个装载有冷却介质的冷箱,冷箱环绕药箱布置于机体的上部,冷箱为环形结构,且其底面与机体的上表面接触,冷箱的内周壁与药箱的侧壁之间形成环形容纳空间,冷箱的内周壁的底部设有若干连通孔,连通孔通过连通管与药箱的内腔相连通,连通管上设有电控阀,电控阀开启使冷箱内的冷却介质流入药箱内以与药箱底部沉积的药液混合。本发明通过冷箱设计有效解决了电机散热效率低的问题,还通过冷却介质与药液的混合防止药液沉积,提高农药利用率和喷洒均匀性。
