[0002] With the rapid development of drone technology, its applications in military, civilian, and industrial fields are becoming increasingly widespread. The power system of a drone is one of its core components, and its performance directly affects the drone's flight performance and endurance. However, the power system generates a large amount of heat during operation. If it is not dissipated effectively and in a timely manner, it can lead to overheating of components such as the engine and motor, thereby affecting their performance and service life, and may even cause malfunctions or safety accidents.

[0003] Traditional drone cooling methods primarily rely on natural convection or simple fan cooling. However, these methods suffer from low cooling efficiency and limited heat dissipation area, making it difficult to meet the high cooling requirements of high-performance drones. Furthermore, traditional cooling designs often separate the heat sink from the fuselage structure, resulting in a large space-consuming and heavy cooling system, and complex installation and maintenance processes.

[0004] To overcome the shortcomings of existing technologies, this invention proposes an integrated heat dissipation structure for the power compartment and fuselage of a UAV. By organically combining the fuselage shell and the power structure, a highly efficient heat dissipation effect is achieved, while simplifying the installation process and improving the overall performance and reliability of the UAV.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] See appendix Figure 1 To be continued Figure 5 This utility model discloses a heat dissipation structure for an integrated load-bearing and heat dissipation system for a drone's power compartment, comprising:

[0042] The drone body 1 has a vertically penetrating mounting cavity 11 in the middle, and air inlet channel 12 and air outlet channel 13 are respectively opened on the front and rear walls of the drone body 1.

[0043] The upper heat dissipation mounting plate 2 and the lower heat dissipation mounting plate 3 are detachably connected to the upper and lower openings of the mounting cavity 11, respectively. The bottom wall of the upper heat dissipation mounting plate 2 has multiple upper ventilation pipes 21, and the bottom wall of the lower heat dissipation mounting plate 3 has multiple lower ventilation pipes 31. The two ends of the upper ventilation pipes 21 and the lower ventilation pipes 31 are respectively connected to the air inlet channel 12 and the air outlet channel 13. The cavity formed by the upper heat dissipation mounting plate 2, the lower heat dissipation mounting plate 3 and the mounting cavity 11 is used to install the power mechanism.

[0044] To further optimize the above technical solution, the exposed surfaces of the upper heat dissipation mounting plate 2 and the lower heat dissipation mounting plate 3 are provided with upper heat dissipation fins 22 and lower heat dissipation fins 32, respectively, which correspond to the sidewalls of the upper ventilation duct 21 and the lower ventilation duct 31. The placement of heat dissipation fins on the exposed surfaces of the upper heat dissipation mounting plate 2 and the lower heat dissipation mounting plate 3 increases the heat dissipation area and further improves heat dissipation efficiency. The correspondence between the heat dissipation fins and the sidewalls of the ventilation ducts allows heat to be dissipated more quickly through airflow, enhancing the heat dissipation effect and helping to better control the temperature of the power system.

[0045] To further optimize the above technical solution, the upper heat dissipation mounting plate 2, lower heat dissipation mounting plate 3, upper ventilation duct 21, lower ventilation duct 31, upper heat dissipation fin 22, and lower heat dissipation fin 32 are all made of aluminum alloy. Using aluminum alloy to manufacture the heat dissipation mounting plate, ventilation duct, and heat dissipation fins is advantageous because aluminum alloy has excellent thermal conductivity, enabling rapid heat transfer and thus improving heat dissipation efficiency. Simultaneously, aluminum alloy is lightweight, minimizing the added weight of the drone and contributing to its lightweight design, thereby enhancing its flight performance.

[0046] To further optimize the above technical solution, both the upper heat dissipation mounting plate 2 and the lower heat dissipation mounting plate 3 are connected to the opening of the mounting cavity 11 by bolts. This detachable connection method facilitates the installation and removal of the heat dissipation mounting plates, making the installation, maintenance, and replacement of the power mechanism more convenient and faster, improving the maintainability of the UAV, and reducing maintenance costs and time.

[0047] To further optimize the above technical solution, a mounting bracket 33 spanning the lower ventilation duct 31 is fixed to the top surface of the lower heat dissipation mounting plate 3. The power mechanism is mounted on the mounting bracket 33. This design makes the installation of the power mechanism more stable, while making full use of the space of the heat dissipation mounting plate, further optimizing the internal spatial layout of the UAV, and improving the compactness of the structure.

[0048] To further optimize the above technical solution, the mounting bracket 33 is fitted to the lower ventilation pipe 31 and is made of aluminum alloy. On the one hand, this ensures the structural strength of the mounting bracket 33, which can reliably support the power mechanism; on the other hand, the aluminum alloy mounting bracket 33, together with the heat dissipation mounting plate and the ventilation pipe, forms an integrated heat dissipation structure, which further enhances the heat dissipation effect and ensures that the heat generated by the power mechanism during operation can be dissipated in a timely manner.

[0049] To further optimize the above technical solution, the front and rear walls of the UAV body 1 are both double-layered structures, and the interior is formed by air inlet pipe 14 and air outlet pipe 15 to form air inlet channel 12 and air outlet channel 13, respectively. This design makes air intake and exhaust smoother, improves airflow efficiency, thereby enhancing the overall performance of the heat dissipation system and providing more effective airflow support for the heat dissipation of the power system.

[0050] To further optimize the above technical solution, both the air inlet duct 14 and the air outlet duct 15 are arranged at an angle, so that the air inlet duct 14 and the air outlet duct 15 form a bending angle with the upper ventilation duct 21 and the lower ventilation duct 31, respectively. This structure can guide the air to flow along a predetermined path, increase the residence time of the air in the heat dissipation structure, improve the heat exchange efficiency between the air and the heat dissipation components, further enhance the heat dissipation effect, and also help optimize the aerodynamic performance of the UAV.

[0051] To further optimize the above technical solution, mesh plates 16 are provided at the openings of the air inlet pipe 14 and the air outlet pipe 15. This can prevent dust, debris and other objects from entering the heat dissipation channel, avoid blockage of the heat dissipation channel, ensure the normal operation of the heat dissipation system, extend the service life of the heat dissipation system, and also help improve heat dissipation efficiency and the reliability of the UAV.

[0052] To further optimize the above technical solution, air vents 211 are provided on both the upper ventilation pipe 21 and the lower ventilation pipe 31, which increases the airflow channel and area, further improves the airflow efficiency and heat dissipation effect, and enables heat to be dissipated more quickly, thereby enhancing the performance of the heat dissipation structure and better meeting the high heat dissipation requirements of high-performance UAVs.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
