Double-cylinder water cooling power device for unmanned aerial vehicle

Abstract

A double-cylinder water cooling power device for an unmanned aerial vehicle comprises an engine component and a power generator component; the engine component comprises a first cylinder and a secondcylinder which are arranged at the two ends; cylinder body cooling boxes are correspondingly arranged on the external side of the first cylinder and the external side of the second cylinder; a circulation cooling component is connected with the cylinder body cooling boxes through cooling pipelines to form a cooling loop; and a cooling liquid flows in the cooling loop in circulation to cool the engine component. By using a water cooling circulation type cooling mode, a cooling speed of an engine can be increased; in particular for a plant protection unmanned aerial vehicle, a double-cylinder engine can be sufficiently cooled by using the circulation cooling component on the premise of not increasing the mounting space; and by combining natural wind power in the unmanned aerial vehicle flying process, a power generator is cooled so that thermal accumulation can be effectively avoided.

Description

Technical field [0001] The invention relates to the technical field of unmanned aerial vehicle power devices, in particular to a double-cylinder water-cooled power device for unmanned aerial vehicles. Background technique [0002] With the development of high and new technology, unmanned aerial vehicle technology continues to make breakthroughs, and unmanned aerial vehicles are bound to get rapid development and wider applications. In the field of unmanned aerial vehicles, although a series of advanced technologies such as visual positioning, high-definition image transmission, and perceptual barriers continue to develop, the fundamental problem of battery life has not been effectively solved. [0003] Multi-rotor drones rely on the lift generated by multiple rotors to balance the gravity of the aircraft so that the aircraft can fly, and control the stability and attitude of the aircraft by changing the rotation speed of each rotor. Therefore, a multi-rotor aircraft can hover and ...

AI Technical Summary

Problems solved by technology

The disadvantages are also obvious. Due to the complex structure, the maintenance is difficult, and the operation requires high requirements for the pilot; the purchase price is relatively expensive; the engine module vibrates greatly, and the service life is not long, etc.

[0005] And because the engine and the generator are combined together, both of them are power components. During the working process, on the one hand, there will be a large vibration, which will affect the stability of the overall structure, easily cause damage to some parts, and reduce the service life. On the other hand, since the heat generated by mechanical movement is not easy to dissipate, in the prior art, in order to reduce the load of the UAV, air cooling is generally used for cooling, the cooling effect is poor, and the high temperature will make the power unit (8) The energy conversion efficiency is lower, and the service life is seriously affected, and it will also bring safety hazards under high temperature conditions
