技术领域technical field
本发明涉及无人机领域，具体是一种燃料电池无人机的动力舱壳体结构。The invention relates to the field of unmanned aerial vehicles, in particular to a power cabin shell structure of a fuel cell unmanned aerial vehicle.
背景技术Background technique
无人机是利用无线电遥控设备和自备的程序控制装置操纵的飞行器。无人机的运行或测试需要控制系统不断产生控制指令而使之发热，一些使用特殊电池的无人机会在电池部分产生大量的热量。一般的无人机会设置散热结构对其内部设备进行散热，但是现在的无人机仅仅在电路板、电机等部分安装散热装置对其进行散热，其他部分散发的热量仍旧会聚集在无人机内部降低无人机的性能且使无人机的使用寿命减短。现行的无人机外壳主要关注锂电池无人机的散热，关于氢燃料电池的散热问题，尤其是燃料电池的散热的问题，相关的研究较少，也较少涉及气瓶的安装问题。若沿用已有的方案，如中国专利(申请号为CN201620590551.2)公开了一种无人机上的燃料电池安全保护装置，其并无涉及燃料电池的散热问题，未着眼于保护燃料电池的安全。还有中国专利(申请号为CN201820051261.X)公开了用于低温环境下无人机燃料电池的隔热和热交换装置，仅关注燃料电池在低温环境下的保温问题。但通常情况下，由于燃料电池工作时发热，无人机的工作环境温度将会有所上升，对无人机的寿命造成的负面影响。Unmanned aerial vehicle is an aircraft controlled by radio remote control equipment and self-provided program control device. The operation or test of the drone requires the control system to continuously generate control commands to make it heat up. Some drones using special batteries will generate a lot of heat in the battery part. General drones will set up heat dissipation structures to dissipate heat from their internal equipment, but current drones only install heat sinks on circuit boards, motors and other parts to dissipate heat, and the heat emitted by other parts will still accumulate inside the drone. Degrades the performance of the drone and reduces the lifespan of the drone. The current UAV casing mainly focuses on the heat dissipation of lithium battery UAVs. Regarding the heat dissipation of hydrogen fuel cells, especially the heat dissipation of fuel cells, there are few related studies, and less related to the installation of gas cylinders. If the existing solution is used, for example, a Chinese patent (application number CN201620590551.2) discloses a fuel cell safety protection device on a drone, which does not involve the heat dissipation problem of the fuel cell, and does not focus on protecting the safety of the fuel cell . There is also a Chinese patent (application number CN201820051261.X) that discloses a heat insulation and heat exchange device for a UAV fuel cell in a low temperature environment, and only focuses on the heat preservation of the fuel cell in a low temperature environment. But usually, due to the heat generated by the fuel cell, the working environment temperature of the UAV will rise, which will have a negative impact on the life of the UAV.

如图1-3所示，本发明的一种燃料电池无人机的动力舱壳体结构，包括与无人机连接的本体1，本体1顶部为与无人机机身连接的连接板11；所述本体1内设置气瓶槽2和电池槽3，所述电池槽3左右两侧内壁分别设置有多条肋4；所述电池槽3前后两侧壁上分别设置有风扇孔31，至少其中一个风扇孔31上设置有风扇，作为最优选的方案，在两个风扇孔31上都设置风扇。所述气瓶槽2包括两个侧壁和两个端部，其中一个端部封闭，另一个端部设置端盖21，端盖21用于在气瓶的轴向限制气瓶活动，该端盖21可以与其相邻的气瓶箍相连。所述气瓶槽2与电池槽3之间设置隔板6，所述隔板6上设置有孔5，所述孔5可用于通过气瓶与燃料电池连接的气管，也可用于电池、无人机控制系统的交互，即可以让信号通过电线从控制系统传到电池从而进行操控。所述气瓶槽2内设置有至少一个气瓶箍22，气瓶箍22用于将气瓶固定在气瓶槽2内。在相邻肋4之间设置有与电池槽3的侧壁外部连通的气孔41，增强散热性能。所述气瓶槽2和电池槽3上下平行设置。电池槽3设置在气瓶槽2下方，其底面还可用于散热，使得电池散热效果更佳。电池槽3内安装电池以后，其顶面与电池的顶部之间具有间隙，便于空气流动。As shown in Figures 1-3, a power cabin housing structure of a fuel cell drone of the present invention includes a main body 1 connected to the drone, and the top of the main body 1 is a connecting plate 11 connected to the drone body The main body 1 is provided with a gas cylinder slot 2 and a battery slot 3, the inner walls of the left and right sides of the battery slot 3 are respectively provided with a plurality of ribs 4; the front and rear side walls of the battery slot 3 are respectively provided with fan holes 31, At least one of the fan holes 31 is provided with a fan. As the most preferred solution, fans are provided on both of the fan holes 31 . The gas cylinder groove 2 includes two side walls and two ends, one of which is closed, and the other end is provided with an end cap 21, which is used to restrict the movement of the gas cylinder in the axial direction of the gas cylinder. The cap 21 may be attached to its adjacent gas cylinder collar. A partition 6 is arranged between the gas cylinder tank 2 and the battery tank 3, and a hole 5 is provided on the partition 6, and the hole 5 can be used for the gas pipe connected to the fuel cell through the gas cylinder, and can also be used for The interaction of the human-machine control system, that is, the signal can be transmitted from the control system to the battery through the wire for control. The gas cylinder groove 2 is provided with at least one gas cylinder collar 22 , and the gas cylinder collar 22 is used to fix the gas cylinder in the gas cylinder groove 2 . Between the adjacent ribs 4, there are air holes 41 communicating with the outside of the side walls of the battery compartment 3 to enhance the heat dissipation performance. The gas cylinder tank 2 and the battery tank 3 are arranged in parallel up and down. The battery slot 3 is arranged below the gas cylinder slot 2, and the bottom surface of the battery slot 3 can also be used for heat dissipation, so that the heat dissipation effect of the battery is better. After the battery is installed in the battery compartment 3, there is a gap between the top surface of the battery compartment 3 and the top of the battery to facilitate air flow.
相邻肋4之间设置有与电池槽3的侧壁外部连通的气孔41，使得多个肋4形成栅栏样式，并非传统的在表面上设计突起，目的是在增强散热的同时，使风能够从栅栏外侧流入电池槽3内，再经由风扇排出，若是按传统的方式设计，风扇的影响仅仅是让电池槽3靠近风扇的区域散热能力增强，而通过栅栏的设计可以使风扇的影响范围更大，提高了散热的效率。肋4可由导热性较好的材料制成，如铜、银、铝合金等。壳体结构的其他部分可使用较轻便、耐热性佳的塑料。Between the adjacent ribs 4, there are air holes 41 that communicate with the outside of the side wall of the battery slot 3, so that the plurality of ribs 4 form a fence pattern, instead of the traditional design of protrusions on the surface, the purpose is to enhance the heat dissipation and to allow wind It flows into the battery slot 3 from the outside of the fence, and then is discharged through the fan. If it is designed in the traditional way, the effect of the fan is only to increase the heat dissipation capacity of the battery slot 3 close to the fan. The design of the fence can make the fan's influence range wider. large, improving the efficiency of heat dissipation. The ribs 4 can be made of materials with good thermal conductivity, such as copper, silver, aluminum alloy, and the like. Lighter, heat-resistant plastics can be used for other parts of the housing structure.
