请同时参阅图3至图5，具体在图示的实施例中，所述无人机100包括机身150、设置于机身150上的动力装置160以及设置于动力装置160上的螺旋桨170。所述控制器、所述第一存储器32、所述测温器34以及所述警报器39均设置于所述机身150上。
所述机身150包括机体151及固定于所述机体151上的机臂153。
所述电池仓200设置于所述机体151上。所述机体151内设有容置腔210，所述容置腔210包括用于安装电池的电池腔及用于安装所述无人机100的控制电路器件的电气腔。具体地，电池腔形成在电池仓200内。所述散热窗设置在所述电池仓200的侧壁上，并与所述容置腔210相连通。
进一步地，所述机体151的上设置有出风口1511。具体地，所述出风口1511设置在所述电池仓200上，并使所述容置腔210与所述机体151的外界相通。所述散热窗设置于所述出风口1511处，所述抽风风扇对应所述散热窗设置。
在本实施方式中，所述机臂153的数量为四个，四个所述机臂153围绕所述机体151设置，并朝向背离所述机体151的方向延伸。每个所述机臂153均大致为中空结构，所述机臂153的壁上设置有所述进风口1531，所述机臂153的内部设有风道1533。所述进风口1531设置于所述机臂153的顶部，所述风道1533与所述容置腔210相连通。所述进风口1531通过所述风道1533及所述容置腔210连通至所述出风口1511。可以理解，所述机臂153的数量可以为一个或多个，例如，两个、三个、六个等等。

当所述无人机100飞行时，所述螺旋桨170转动引起空气流动，即，螺旋桨170会产生向下的气流，所述气流从所述进风口1531进入所述风道1533及所述容置腔210内，并经由所述出风口1511流出。所述测温器34用于感测所述容置腔210的温度，所述控制器用于根据所述测温器34感测的温度，控制所述风扇54的工作状态。所述散热窗56能够自动开启与关闭，并且在所述风扇54开启时自动开启，在所述风扇54关闭时自动关闭。
当所述无人机100飞行时，所述螺旋桨170产生的一部分气流会由所述进风口1531进入电池仓200的所述容置腔210内，此时所述风扇54开启，会将电池仓200内的空气经由所述散热窗56导出电池仓200外，进一步加强了电池仓200内外的空气对流，避免了电池仓200的内部空间狭小所造成的空气不流通的现象，进一步提高了散热效率。
需要说明的是，在上述实施例中，所述出风口1511由所述散热窗56及百叶窗控制打开或关闭。当然，在其他实施例中，所述出风口1511也可以用其他方式来控制。另外，所述进风口1531也可以打开与关闭，例如，进风口1531设有百叶窗，并且对应进风口1531设有吸气风扇，通过吸气风扇、百叶窗控制进风口1531的打开与关闭。
