Description

technical field [0001] The invention relates to the technical field of drone engines, in particular to a liquid-cooled (water-cooled, oil-cooled) temperature control system for drone engines and an implementation method thereof. Background technique [0002] The UAV engine cooling system (hereinafter referred to as the UAV cooling system) is an important part of the UAV. Its function is to cool the excess heat generated during the operation of the engine and maintain the engine temperature within a certain range to ensure the continuous and stable operation of the engine. , its cooling effect directly determines the reliability and service life of the UAV engine. [0003] At present, the cooling system of drones mainly includes natural cooling, forced air cooling and liquid cooling. Natural cooling is through the heat sink of the engine block in contact with the outside air. When the engine is working, the natural wind flows to cool the engine; forced air cooling is more nat...

AI Technical Summary

Problems solved by technology

[0004] 1. Natural cooling is greatly affected by the external ambient temperature, and the cooling efficiency is low, which cannot meet high temperature weather and long-term operation;

[0005] 2. The fan cooling system with forced air cooling, on the one hand, will increase the extra weight of the engine and reduce the power-to-weight ratio of the engine; Poor reliability;

[0006] 3. The forced air cooling is an open-loop control, which cannot be changed with the change of the external environment temperature, and the fan generates a lot of heat and has poor cooling effect when it runs for a long time;

[0007] 4. The liquid-cooled heat dissipation coolant is easy to leak and is easily affected by climate change. For example, the temperature is low in winter, and the engine needs a long time to warm up the car before it can run normally
