[0002] At present, piston engines are usually selected as the power source for small unmanned aerial vehicles. This type of unmanned aerial vehicle has the characteristics of convenient transportation, flexibility, and is particularly suitable for low-altitude economic fields such as disaster relief and emergency rescue. Therefore, it is becoming increasingly important for unmanned aerial vehicles to have the ability to fly in the rain and be able to perform tasks all-weather.

[0003] The main problem with rain protection for existing unmanned aerial vehicle engines lies in waterproofing the engine intake. Currently, the main technical means for rain protection is to add a waterproof structure to the air filter for passive rain protection. This passive means cannot ensure that rainwater cannot enter the engine intake duct at all. Especially when the rainfall is greater than moderate rain level, due to the poor rain protection effect, once rainwater enters the engine intake system, it may cause the engine to stall, which is extremely harmful to the unmanned aerial vehicle. Content of the Utility Model

Detailed embodiments

[0031] The following will specifically describe the preferred embodiments of the present utility model in conjunction with the accompanying drawings. Among them, the accompanying drawings form a part of the present utility model and are used together with the embodiments of the present utility model to explain the principle of the present utility model, rather than to limit the scope of the present utility model.

[0032] Embodiment 1

[0033] A specific embodiment of the present utility model, as Figure 1 and Figure 2 shown, the present utility model provides an intercooler for a drone, including an air inlet duct 1, a radiator tube bundle 2 and an air outlet duct 3. A plurality of radiator tube bundles 2 are arranged in parallel in the middle of the intercooler. The air inlet duct 1 and the air outlet duct 3 are arranged in parallel on both sides of the intercooler. The two ends of the radiator tube bundle 2 are respectively connected and communicated with the air inlet duct 1 and the air outlet duct 3 to form a channel for gas to flow into and out of the intercooler. The heat dissipation principle of the intercooler of the present utility model is the same as that of the traditional intercooler.

[0034] The air inlet duct 1 includes a water collecting tank 11, an air inlet 12 and an end plate 13. The water collecting tank 11 is arranged at the bottom of the air inlet duct 1, and the bottom plate 111 of the water collecting tank 11 is lower than the bottom of the radiator tube belt 2, so that the water collecting tank 11 has a certain capacity. Optionally, the water collecting tank 11 and the air inlet duct 1 are an integrally formed housing. When rainwater enters the air inlet duct 1, the rainwater will fall on the bottom plate 111 under the action of gravity. Since the bottom plate 111 is lower than the bottom of the radiator tube belt 2, the rainwater on the bottom plate 111 will be deposited in the water collecting tank 11 and will not flow into the radiator tube belt 2, thus providing a buffer space for the rainwater entering the engine air inlet duct.

[0035] Optionally, as Figure 2 shown, the bottom plate 111 includes an inclined plate 1111 and a horizontal plate 1112. The high end of the inclined plate 1111 is connected to the end plate 13, and the low end is connected to one end of the horizontal plate 1112, so that after the rainwater flowing into the air inlet duct 1 contacts the end plate 13 and the inclined plate 1111, it will slide down onto the horizontal plate 1112. Since the position of the horizontal plate 1112 is lower, it is convenient to centrally collect rainwater here to prevent the rainwater from flowing back into the radiator tube belt due to the bumping or tilting of the drone. The position between the inclined plate 1111 and the horizontal plate 1112 can be adjusted. The horizontal plate 1112 can also be located on the side close to the end plate 13, or two inclined plates 1111 can be arranged, and the horizontal plate 1112 is located between the two inclined plates 1111.

[0036] Optionally, a water immersion sensor 4 is arranged on the horizontal plate 1112. When rainwater enters the engine air inlet duct and is deposited on the horizontal plate 1112, the water immersion sensor 4 can monitor and alarm in time. Due to the function of the inclined plate 1111, the rainwater on the bottom plate 111 is concentrated on the horizontal plate 1112, and the area of the horizontal plate 1112 is small. Even if the water volume is small, the water immersion sensor 4 can detect the water immersion state, so that the monitoring and alarm functions of the water immersion sensor 4 are more sensitive and timely.

[0037] Optionally, a drain hole is also arranged on the horizontal plate 1112, and a drain plug 5 is inserted into the drain hole. When the drone lands, the drain plug 5 can be unscrewed to drain the water in the water collecting tank 11 from the drain hole.

[0038] Optionally, as Figure 2 and Figure 3 shown, one end of the radiator tube belt 2 communicating with the air inlet duct 1 extends out a water baffle 21. Since the engine intake has a certain pressure, the water baffle 21 can block the rainwater at the entrance of the radiator tube belt 2, and the rainwater blocked by the water baffle 21 will fall into the water collecting tank 11 due to gravity.

[0039] Optionally, as Figure 3As shown, the radiator tube belt 2 is a rectangular plate, and the water baffle 21 is a long strip plate extending from one end of the radiator tube belt 2. The water baffle 21 is flush with the side of the radiator tube belt 2 facing the air inlet 12 to prevent rainwater on the water baffle 21 from entering the radiator tube belt 2, thus playing a role in blocking water.

[0040] Embodiment 2

[0041] The difference between the intercooler of the drone in this embodiment and that in Practical Example 1 is that, as Figure 4 and Figure 5 shown, the water baffle 21 in this embodiment includes an arc-shaped side plate 211, and the convex arc surface of the side plate 211 faces the air inlet 12.

[0042] When the rainwater in the air inlet passage 1 is blocked by the water baffle 21, due to the certain pressure of the engine intake air, the arc surface of the side plate 211 generates a centrifugal force on the rainwater, causing the rainwater to move away from the inlet of the radiator tube belt 2, and then falling into the water collecting tank 11 under the action of gravity.

[0043] By providing the arc-shaped side plate 211, the water baffle 21 in this embodiment can improve the water blocking effect of the water baffle 21, more effectively prevent rainwater from entering the radiator tube belt 2, and protect the normal operation of the engine.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
