[0026] Specifically, the top of cooling liquid storage box 9 is fixedly connected with support frame 10, the inner wall bottom surface of support frame 10 is fixedly connected with multiple sets of buffer springs 11, the top of buffer spring 11 is fixedly connected with mounting plate 12, and the top of mounting plate 12 is fixedly connected with the bottom of water pump 8, mounting plate 12 is placed in the inside of support frame 10, and the outside of mounting plate 12 is attached with the inner wall of support frame 10, to prevent mounting plate 12 from tilting when moving.

[0027] Further, the top of mounting shell 2 is embedded with top cover 13, the bottom of top cover 13 is equipped with sealing ring 14, and sealing ring 14 is embedded in the inside of mounting shell 2, sealing ring 14 can improve the tightness of top cover 13 and mounting shell 2 connection, to prevent external dust from entering the inside of device.

[0028] Further, the outer side of the cold water pipe 7 is sleeved with a support frame 15, and the bottom end of the support frame 15 is fixedly connected with the top end of the cooling liquid storage box 9. The support frame 15 supports the cold water pipe 7 and prevents the cold water pipe 7 from shaking.

[0029] It is worth noting that the inner bottom surface of the mounting shell 2 is fixedly connected with a support block 16, the top end of the support block 16 is fixedly connected with a buffer pad 17, and the top end of the buffer pad 17 is attached to the bottom surface of the hybrid device body 3. The support block 16 supports the hybrid device body 3, separates the hybrid device body 3 from the mounting shell 2, and effectively diffuses the temperature.

[0030] It is worth noting that the inner side of the mounting shell 2 away from the cooling liquid storage box 9 is embedded with a cooling fan 18, and the inner side of the mounting shell 2 away from the cooling liquid storage box 9 is embedded with a dust screen 19.

The material of the heat insulation plate 21 is ceramic fiber. The heat insulation plate 21 separates the hybrid device body 3 from the cooling liquid storage box 9, avoiding the influence of the heat generated by the hybrid device body 3 on the cooling liquid storage box 9.

[0034] Working principle and process:

[0035] In the installation of the hybrid device body 3 to the inside of the unmanned aerial vehicle shell 1, through the mutual clamping of the first triangular clamping block 5 and the second triangular clamping block 6, the heat dissipation plate 4 is fixed, and then the top cover 13 is screwed to the top end of the installation shell 2 to seal it. When the hybrid unmanned aerial vehicle is used, the fuel engine and the battery and other devices in the hybrid device body 3 will generate a lot of heat during operation. The heat dissipation plate 4 absorbs heat, and the water pump 8 stores the cooling liquid in the cooling liquid storage box 9 through the cold water pipe 7 to absorb the heat absorbed by the heat dissipation plate 4, so that the heat dissipation plate 4 can continuously absorb the heat generated by the hybrid device body 3 and cool it down. The heat insulation plate 21 can isolate the hybrid device body 3 from the cooling liquid storage box 9 to prevent the cooling liquid storage box 9 from directly absorbing heat, improve the working efficiency of the cooling liquid storage box 9, and start the cooling fan 18 to accelerate the internal air circulation and diffuse the internal temperature to the outside to achieve rapid cooling. At the same time, under the action of the dust screen 19, the dust in the outside air is effectively prevented from entering the inside of the installation shell 2, preventing the dust from damaging the internal fuel engine and battery and other devices, preventing the risk of unmanned aerial vehicle crash due to high internal temperature, and preventing the vibration generated by the water pump 8 from being transmitted to other components when the water pump 8 is used. The installation plate 12 pushes the buffer spring 11 up and down to reduce vibration, avoiding the vibration generated by the water pump 8 from being transmitted to other components, improving the stability of the internal parts, making the unmanned aerial vehicle fly more stably, and under the action of the polished rod 20, the installation plate 12 can move stably and will not deviate during the downward movement, so that the buffer spring 11 can effectively reduce the vibration.
