Description

Take heat abstractor's unmanned aerial vehicle

Technical Field

The utility model relates to an unmanned air vehicle technique field, in particular to take heat abstractor's unmanned aerial vehicle.

Background

Unmanned aerial vehicles, also called unmanned aerial vehicles, have been widely used in various fields. The majority of present unmanned aerial vehicles are driven by motors in order to facilitate better control. However, the motor can generate a large amount of heat energy in the using process, particularly, the motor is high in rotating speed and high in power, if the heat energy cannot be dissipated effectively in time, the performance of the motor can be seriously influenced after long-term use, the service life of the motor is shortened, and therefore a heat dissipation device is usually configured in the unmanned aerial vehicle, and particularly, the water-cooling heat dissipation is taken as a main part. Among the unmanned aerial vehicle water-cooling heat abstractor of present, need realize hydrologic cycle with motor-driven pump, need consume the electric energy, and then reduced unmanned aerial vehicle's duration.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a take heat abstractor's unmanned aerial vehicle need not to consume the electric energy and also can realize the heat dissipation.

In order to realize the purpose of the utility model, the embodiment of the utility model provides a following technical scheme:

the utility model provides a take heat abstractor's unmanned aerial vehicle, includes the unmanned aerial vehicle body, the unmanned aerial vehicle body includes a plurality of rotor, and every rotor is by a motor drive, still includes a plurality of radiator fan, and radiator fan's size is greater than the size of motor, so that the rotatory produced wind energy of rotor drives radiator fan's flabellum and rotates. In this scheme, a heat dissipation fan constitutes a heat dissipation device.

In above-mentioned scheme, radiator fan is not by motor drive, but the wind energy drive that utilizes the rotor to produce, and the wind energy that unmanned aerial vehicle rotor produced when flying is the natural existence, consequently, unmanned aerial vehicle in the above-mentioned scheme can realize dispelling the heat to the motor, can not consume the electric energy again, realizes "no power supply (actually is the mechanical energy that the wind energy converts the fan)" heat dissipation, and then can prolong unmanned aerial vehicle's duration.

In one embodiment, the number of the heat dissipation fans is the same as the number of the motors, and one heat dissipation fan is used for dissipating heat for one motor. The method has two advantages, one is that one cooling fan only cools one motor, so that each cooling fan can be miniaturized; secondly, because the rotor is the symmetry and sets up, so make radiator fan also the symmetry set up, can ensure unmanned aerial vehicle's whole focus is balanced, simplifies control.

In a further optimized scheme, the motor heat dissipation device further comprises a plurality of closed water pipes, the number of the closed water pipes is the same as that of the motors, one closed water pipe dissipates heat for one motor, and one heat dissipation fan dissipates heat for one closed water pipe. In the scheme, a heat radiation fan and a closed water pipe jointly form a heat radiation device. Utilize the water pipe heat dissipation at this scheme, the heat conduction of motor to the water pipe for cold water in the water pipe becomes hot water, and water in the water pipe is fixed, but dispels the heat to the water pipe through radiator fan, can make in the water pipe hydrothermal heat pass through water pipe wall conduction to the air in, realizes the heat dissipation, improves the radiating efficiency through the water-cooling heat dissipation.

In another embodiment, still include a non-closed water pipe and no motor's circulating pump, closed water pipe is all motor heat dissipations simultaneously, and the both ends of non-closed water pipe communicate with the water inlet and the delivery port of no motor's circulating pump respectively, radiator fan includes a plurality of flabellums and a pivot, and the flabellum is fixed in the pivot, the impeller of no motor's circulating pump is connected with radiator fan's pivot to make radiator fan drive the impeller and rotate. In the scheme, the heat radiation fan, the non-closed water pipe and the circulating pump without the motor jointly form a heat radiation device.

In the above scheme, dispel the heat through a water pipe to all motors, realize the hydrologic cycle through the circulating pump, however the circulating pump does not have motor drive, but by radiator fan drive, and radiator fan rotates under the produced wind energy drive of rotor, drives the impeller rotation then for rivers in the water pipe realize the circulation flow.

Compared with the prior art, the utility model provides an among the unmanned aerial vehicle, dispel the heat to the motor through setting up heat abstractor for the motor can use longer time, reduces the cost of motor among the unmanned aerial vehicle then. Utilize radiator fan to dispel the heat to the motor, but radiator fan work need not motor drive, but is driven by the wind energy that the rotor produced, consequently need not direct consumption electric energy, and original power to unmanned aerial vehicle influences lessly, also does not increase weight, can prolong unmanned aerial vehicle's time of endurance then. In addition, the wind-force that the rotor provided is just big when motor speed is fast, then the fan is rotatory fast, and the heat dissipation is fast, and the wind-force that provides when the rotor dispels the heat relatively slowly for the hour, but motor speed is also slow this moment, consequently is enough to dispel the heat, that is to say the utility model discloses in the scheme, the radiating efficiency can the automatic adaptation motor needs, and need not artificial control, neither need increase control system's complexity, again can the adaptability adjust, the heat dissipation when electric energy when avoiding the low demand of motor is excessively extravagant and high demand is not good.

In this embodiment, the non-enclosed water pipe 60 is a larger water pipe, and is used for dissipating heat of three motors, for example, a semicircular water pipe, and is disposed below the three motors. It should be noted that, in the present embodiment, for a six-rotor drone, two non-closed water pipes 60 are provided and symmetrically provided, so that one non-closed water pipe 60 adopts a semicircular or triangular structure to dissipate heat for three motors therein, and for other designs, the number and the shape of the non-closed water pipes 60 may be adaptively changed.
