在本申请的实施例中,该第一壳体11与第二壳体12为上下配合的结构。其中,第二壳体12与散热片3密封装配以构成散热通道14,入风口121和出风口122设置于第二壳体12上,散热片3相对电路板2靠近入风口121和出风口122。该实施例中,该入风口121和出风口122分设于所述散热通道14的相对两端,具体地入风口121设置于无人飞行器100的前部,出风口122设置于无人飞行器100的后部,如此在无人飞行器100飞行过程中便于气流从入风口121进入,从出风口122流出,从而可以加快散热通道14里的气流的流速,加快为散热片3散热。
该第二壳体12还包括覆盖于入风口121的第一防尘网16和/或对应于出风口122的第二防尘网17。该实施例中,在入风口121覆盖有第一防尘网16,在第二出风口122覆盖有第二防尘网17,其中,第一防尘网16和第二防尘网17的防护等级为IP4X,4表示防尘等级,X表示防水等级,所以IP4X就是防止物体大于1mm的固体侵入,如此以使第一防尘网16和第二防尘网17在满足气体顺畅流动的同时,可以满足防尘防水的需求。
在第二壳体12与散热片3密封装配的实施例中,该散热片3面向第二壳体12的侧面设有连接圈31,第二壳体12上设有与连接圈31密封装 配的装配圈123。其中,通过连接圈31与装配圈123的装配以使第二壳体12与散热片3密封装配。
在一实施例中,如图5至图8所示,连接圈31和装配圈123中的一者包括凹槽圈,另一者包括凸筋圈。其中,凸筋圈插置入凹槽圈内,与凹槽圈密封装配。本申请的图示中,该凸筋设置在第二壳体12上,凹槽圈设置在散热片3上。该凸筋配合第二壳体12和散热片3构成了散热通道14。
进一步地,该凹槽圈和凸筋圈之间设有密封圈32。其中,密封圈32在凸筋圈的抵持下密封凸筋圈与凹槽圈之间的间隙,从而可以进一步确保第二壳体12与散热片3之间的密封装配。
该第二壳体12的边缘设有连接部126,第二壳体12通过该连接部126与第一壳体11密封装配,第二壳体12上的装配圈123相对所述连接部126靠近第二壳体12的中心位置。在一实施例中,该连接部126为连接面,连接面上设有多个连接孔,螺钉穿过该连接孔连接于第一壳体11上,以使第一壳体11与第二壳体12装配。此外,为了增强密封效果,该连接面与第一壳体11之间还可以装配密封圈(未图示)。
本申请的散热片3包括板状主体33、散热鳍片34及风扇35。该散热鳍片34和风扇35设置于板状主体33朝向散热风道的侧面,散热鳍片34和风扇35位于连接圈31内。该风扇35对应于入风口121,用于辅助加快散热通道14内气流流动。该散热片3采用导热系数较高的金属材料,如铝、铝合金、铜及铜合金等。
其中,为了保证散热片3的密封性,该风扇35采用防水电机驱动扇叶转动,板状主体33上设有开孔,风扇35包括电源线,该电源线连接于防水电机。其中,电源线穿过开孔以与电路板2电连接,电源线与开孔之间的间隙填充有密封胶,如此即使有水侵入散热通道14内,也不会通过散热片3渗入到电路板2所在的电路盒10的内部。
在一实施例中,如图5和图6所示,第一壳体11为下端开口的盒状,第二壳体12为盖状。该入风口121和出风口122设置于第二壳体12与散热片3相对的侧面,风扇35为离心风扇,如此以将气流从电路盒10的下方吸入散热通道14,而后通过出风口122从电路盒10的下方流出。该实施例中,第二壳体12为无人飞行器100的底面壳体1,即该入风口121和出风口122设置于无人飞行器100的底面壳体1上,该结构设计可以避免其他结构阻挡气流的进入和流出,有利于散热通道14为散热片3散热。
其中,该第二壳体12还包括用于将散热风道内的气流引导向出风口122的引导面15,该引导面15包括与出风口122连接的连接端151以及远离出风口122的自由端152,连接端151连接于出风口122远离入风口121的一侧,自由端152相对连接端151靠近入风口121。该引导面15可以是倾斜平面也可以是倾斜的弧形面。该实施例中,第二壳体12上的装配圈123经过引导面15时,该部分的装配圈123设置于该自由端152上。
在又一实施例中,如图7所示,该第一壳体11为下端开口的盒状,第二壳体12包括向外凸起的凸盖124,凸盖124包括朝向远离散热片3方向延伸出的侧壁1241,入风口121和出风口122设置于凸盖124的相对侧壁1241上,如此设置以使经过入风口121和出风口122的气流位于水平方向上。该风扇35为轴流风扇,可以进一步加快散热通道14内气流流动的速度,从而加快为散热片3散热。
如图3至图5结合图9所示,上文中提出了通过散热片3为电路板2进行主动散热。要提高散热效率,除了通过选择良好导热系数的材料制造散热片3、以及选择合适的风扇35外,电路板2与散热片3的间隙的控制也很关键。本申请的电路盒10还包括抵接于散热片3与电路板2之间的限位柱36,以使散热片3与电路板2保持间距D,该限位柱36设置于电路板2和散热片3中的至少一者。
本实施例中,为了释放电路板2上的空间,该限位柱36设置于散热 片3上。该限位柱36为多个,多个限位柱36可以均匀地分设于散热片3与电路板2之间,如此以保证散热片3与电路板2之间的间距一致性,同时通过限位柱36抵接在散热片3与电路板2之间,能保证电路盒10在受到冲击时,散热片3与电路板2之间具有支撑,仍然能保持间距在散热理想范围内,且避免散热片3与电路板2撞件。
其中,该散热片3与电路板2之间的间距D范围为0.2mm-0.5mm。优选地,该散热片3与电路板2之间的间距D为0.3mm。
进一步地,该电路板2与散热片3之间的间距D内设有导热层(未图示),通过该导热层的设置以加快电路板2的热传导,从而提高电路板2的散热效率。其中,该导热层包括导热泥和/或导热垫。
该电路板2包括功率器件,功率器件包括处理芯片、二极管、电容、电阻及三极管等中的至少一种。散热片3还设有导热凸台37,导热凸台37位于散热片3面向电路板2的侧面且对应于功率器件,即导热凸台37延伸向功率器件但与功率器件不接触。该导热凸台37的数量可以对应功率器件的数量进行设置,也可以根据部分功率器件均匀设置于电路板2上。
目前市场上电子设备的壳体大多为注塑、压铸工艺。对于要求重量尽量小的设备,设备壳体可以采用碳纤维工艺。但是,当电子设备的尺寸达到一定值后,注塑产品容易出现出模变形问题,同时异形碳纤维产品由于采用模压工艺,尺寸精度并不高。以一款尺寸为400×200×40mm的异形碳纤维壳体为例其尺寸精度仅能达到±0.5mm左右,精度较差,而散热片3和电路板2的理想间距是0.3mm。因此,需要一种较高精度的配合以满足散热片3和电路板2的间距需求。
有鉴于此,本申请的第一壳体11的材料包括炭纤维,和/或第二壳体12的材料包括塑胶。在本申请的实施例中,第一壳体11由炭纤维材料制成,有利于减轻电控盒的重量。第二壳体12由塑胶材料制成,以便于与 第一壳体11的密封装配。
为了使第二壳体12、散热板和电路板2堆叠地装配于第一壳体11。该第一壳体11和电路板2中的一者设有第一定位柱111,另一者设有第一定位孔21。其中,通过第一定位柱111与第一定位孔21的配合装配,以使电路板2初定位于第一壳体11。该实施例中,第一定位孔21设置于电路板2上,定位柱设置在第一壳体11内,该定位柱与定位孔配合的定位结构可以为多组。
而后,为了保证散热片3和电路板2配合装配的准确性,该电路板2和散热片3中的一者设有第二定位柱22,另一者设有第二定位孔38。其中,通过第二定位柱22与第二定位孔38的配合装配,以使电路板2装配于散热片3。该实施例中,第二定位柱22设置在散热片3上,第二定位孔38设置于电路板2上,该散热片3与电路板2之间可以通过螺钉固定连接,以保证散热间距。
最后,通过第二壳体12上的螺丝柱与散热片3上的套筒形定位孔配合导向,同时第二壳体12上的装配圈123与散热片3上的连接圈31的配合以使第二壳体12与散热片3精准配合装配。而后通过第二壳体12外打螺钉以将散热片3及电路板2的组件串接起来并固定在该第二壳体12上。
在整机装配时,其他模块装配于第一壳体11内后,模块的线缆和FPC线缆12穿好在第一壳体11内,考虑装配合理性和避免过长的余线,由于电路板2先放到第一壳体11内,因此不需要为了装配让手更好操作而将动力线缆13和FPC线缆12等预留很长一段,也减少了整理线路的操作,间接简化了装配工作。该电路板2在初定位第一壳体11内之前,电路板2靠近第一壳体11时,预先将各个线缆连接于电路板2。而后通过螺钉将电路板2与散热片3固定连接,最后通过第二壳体12外打螺钉以将散热片3及电路板2的组件固定在该第二壳体12上,如此以使电路盒10实现一种相对较简单的装配方式。
本申请设计了一种电路盒及具有该电路盒的无人飞行器,该电路盒将主动散热的散热通道和风扇布置在外环境,散热片和电路板相互固定,散热片与外壳之间形成散热通道且有防水设计。该电路盒能够实现满足电子设备的主动散热并且满足ipx4的防水需求,同时装配相对简单。
