Description

Technical Field

[0002] In recent years, my country's drone technology has been fully developed. In the design of high-speed drones, target drones that are rocket-assisted and parachuted for recovery are used. They have the characteristics of high flight efficiency and accurate simulation accuracy, and are widely used in military training and actual combat exercises. The temperature control of equipment in the cabin of high-speed drones is the focus of equipment safety work and the basis for the safe and stable flight of drones. However, the power supply, data link airborne terminal, inertial navigation and other equipment of the drone body generate a lot of heat during long-term operation, and are easily subject to space constraints, which can easily cause heat accumulation. Most of the existing heat dissipation methods are passive heat dissipation through heat sinks. However, since the external mounting structure design of existing airborne equipment is mostly metal structure, although it can shield to achieve a good electromagnetic compatibility effect, the body is bulky and the heat dissipation effect is poor.

[0003] To this end, the utility model provides a heat dissipation device for high-temperature equipment in a target aircraft cabin. Utility Model Content

At the same time, the high-temperature power supply components of the target aircraft and the heat dissipation structure can be started synchronously to ensure that the high-temperature power supply components of the target aircraft can achieve a cooling effect during the entire process of use, thereby ensuring the safety of the drone.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a heat dissipation device for high-temperature equipment in a target aircraft cabin, including a heat dissipation structure installed on a high-temperature power supply component of the target aircraft, the heat dissipation structure including a front radiator, a rear radiator, a front cooling fan and a rear cooling fan, the front radiator corresponds to the front cooling fan, the rear radiator corresponds to the rear cooling fan, a front mounting frame and a rear mounting frame are respectively installed on both sides of the high-temperature power supply component of the target aircraft, an upper bracket is installed between the front mounting frame and the rear mounting frame, and the upper bracket corresponds to the front cooling fan and the rear cooling fan.

[0006] Furthermore, a screw mounting seat is fixed to the bottom of the high-temperature power supply component of the target drone, and a plurality of mounting screws are installed between the screw mounting seat and the front mounting frame and the rear mounting frame.

[0007] Furthermore, a screw extension rod is installed between the screw mounting seat and the front mounting frame, and the screw extension rod corresponds to the mounting screw.

[0008] Furthermore, the upper bracket is fixedly connected to the front mounting bracket and the rear mounting bracket, and two mounting grooves are provided in the upper bracket, and the two mounting grooves correspond to the front cooling fan and the rear cooling fan respectively.

[0009] Furthermore, an adjustable flexible gasket is installed between the front mounting frame and the upper bracket to achieve adaptability to tolerance during the installation process.

[0010] Furthermore, a radiator positioner is installed on the upper side of the high-temperature power supply component of the target drone, and the radiator positioner corresponds to the front radiator and the rear radiator.
