一种散热性能良好的系留无人机线缆收放装置

系留无人机工作时系留线缆产生大量热量,使系留线缆温度迅速升高。文中提出了一种散热性能良好的系留无人机线缆收放装置实施方案,通过绕线筒的双层结构设计使得绕线筒内部有较大的散热空间,在强迫风冷散热方式下,绕线筒内部和外部形成了畅通的冷风流动通道,有效地带走了电流流经系留线缆时产生的热量。在系留线缆的盘绕方式上,把系留线缆分隔成若干部分,解决了集中发热的问题。热仿真分析和试验测试的结果表明,在预定的物理条件下,线缆收放装置的散热效果达到了预定的技术要求,具有较好的实用价值。

Tethered UAV Cable Launch and Recovery Device with Good Heat Dissipation Performance

When the tethered UAV works, the tethering cable generates large amount of heat, and the temperature of the cable rises rapidly. In this paper, an implementation scheme of a tethered UAV cable launch and recovery device with good heat dissipation performance is proposed. Through the double-layer structure design of the winding drum, there is a large heat dissipation space inside the winding drum. Under the heat dissipation method of forced air cooling, the inside and outside of the winding drum form smooth cold air flow channels, effectively takes away the heat generated by the current flowing through the tethering cable. As for the coiling mode of the tethering cable, the problem of concentrated heating is solved by dividing the tethering cable into several parts. The results of thermal simulation analysis and test show that under the predetermined physical conditions, the heat dissipation effect of the cable launch and recovery device meets the predetermined technical requirements and has good practical value.
