除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本申请。
为方便理解，下面先对本申请实施例中所涉及的技术术语进行解释和描述。

无人飞行器、无人车等可移动平台已经成为人们生活、工作和娱乐过程中必不可少的科技产品。然而，可移动平台的品牌繁多，使得可供消费者选择产品很多，如何获得消费者的青睐，提升产品竞争力越来越受到可移动平台厂家的重视。在功能或性能相近的可移动平台产品中，可移动平台的体积越小，越能获得消费者或体检中心等医疗机构的青睐。因此，可移动平台小型化的发展，成了可移动平台厂家越来越重视的问题。
但传统的可移动平台的散热结构整体体积较大且比较笨重，不利于可移动平台小型化的发展。
基于此，本申请提供一种散热结构。该散热结构能够充分利用散热气流，有利于降低可移动平台的功耗。
为了更好地理解本申请的散热结构，通过应用了该散热结构的可移动平台进行阐述。
如图1至图7为一些实施例中所示可移动平台及其散热结构的结构示图。其中，图1为一实施例中所示的可移动平台的结构示意图。图2为一实施例中所示的可移动平台的俯视示意图(去除了机身顶部零件)。图3为一实施例中所示的散热结构的俯视示意图。图4为图3所示的散热结构的A-A剖视示意图。图5为图4所示的A的放大示意图。图6为图4所示的B的放大示意图。图7为图3所示的散热结构的结构示意图。
如图1至图3所示，本申请的实施例提供一种可移动平台，包括机身10、散热结构20以及第一被散热组件30，散热结构20设置于机身10。
其中，如图3至图6所示，散热结构20包括散热支架100、气流产生组件200以及分流组件300。散热支架100内设有至少两条散热风道110，每条散热风道110分别包括进风端111，散热风道110的侧壁设有第一安装部120，用于安装第一被散热组件30。气流产生组件200设置于散热支架100，用于产生散热气流，气流产生组件200包括出风部210，出风部210朝向至少两条散热风道110的进风端111设置。分流组件300通过散热支架100设置于出风部210与至少两条散热风道110的进风端111之间，以控制进入每条散热风道110的散热气流的流量大小。如此，利用分流组件300可以控制进入每条散热风道110的散热气流的流量大小，对散热气流进行合理的分配，进而能够充分利用散热气流对第一被散热组件30进行散热，提高散热效率。
该可移动平台使用时，第一被散热组件30可以设置于散热风道110的侧壁上，将其运行时产生的热量传递到散热风道110上，利用散热风道110进行散热。同时，气流产生组件200设置于散热支架100上，能够为散热风道110提供散热气流，以提高散热风道110的散热效率，进而能够使得第一被散热组件30的散热效果好；此外，利用分流组件300可以控制进入每条散热风道110的散热气流的流量大小，对散热气流进行合理的分配，进而能够充分利用散热气流对第一被散热组件30进行散热。如此，通过调整散热气流的分配来满足不同散热风道110上的散热需求；同等条件下，无需提高气流产生组件200的功率来满足散热需求，进而有利于降低可移动平台的功耗，提高续航能力。
可以理解地，当有散热风道110内的散热气流不足，而又有散热风道110内的散热气流过量(也即，在该散热风道110上的第一被散热组件30的温度还未到达额定耐 热温度)；此时，利用本申请的散热结构20无需提高气流产生组件200的功率来产生更多散热气流，可以先利用分流组件300来调整散热气流的分配来降低进入散热气流过量的散热通道内的散热气流的流量，而提高需要增加散热气流的散热风道110内的散热气流的流量。如此。可以提高散热气流的利用率，而降低散热的功耗。
或者，可以根据多个第一被散热组件30之间的耐热能力的不同，将耐热温度较高的第一被散热组件30设置于一个散热流道上，而将耐热温度较低的第一被散热组件30设置于另一个散热流道上。如此，利用分流组件300将更多地散热气流送入耐热温度较低的第一被散热组件30所在流道上。进而也能够实现充分利用散热气流进行散热，降低散热的功耗。
在某些实施方式中，可移动平台还可以包括汽车、遥控车、机器人或相机。当激光雷达应用于汽车时，本体为汽车的车身。该汽车可以是自动驾驶汽车或者半自动驾驶汽车，在此不做限制。当激光雷达应用于遥控车时，本体为遥控车的车身。当激光雷达应用于机器人时，本体为机器人的机身10。当激光雷达应用于相机时，本体为相机的本身。
示例性的，如图1及图2所示，可移动平台为无人飞行器，该散热结构20设置于机身10，以提高无人飞行器的散热利用率，降低无人飞行器的功耗，而有利于提高无人飞行器的续航能力。
需要说明的是，气流产生组件200的具体数量可以根据散热风道110的数量灵活进行设置。可选地，一个气流产生组件200可以对应两个散热风道110。
对于散热要求较高的第一被散热组件30，亦可以集成到散热支架100上来，充分利用散热风道110进行散热，可以使可移动平台的结构更加紧凑，有利于可移动平台小型化。
再者，将至少部分第一被散热组件30设置于散热支架100上，可以利用散热支架100作为安装件使用，便于将第一被散热组件30模块化组装于机身10内，有利于提高组装效率。
示例性的，如图4所示，散热结构20包括一个气流产生组件200，并将该气流产生组件200安设于散热支架100上。如此，使得散热结构20更加紧凑，且重量更轻，有利于可移动平台小型化和轻量化发展。进而，可以减少包装材料，进而降低包装成本，进而也是有利于降低成本。此外，体积越小，越能够降低搬运难度，进而能够提 高用户体验；而且，占用空间小，在同等存储空间情况下，可以存储更多的物料，降低可移动平台的仓储成本及运输成本。
目前，随着可移动平台的应用越来越广，应用的环境越越来越复杂，对可移动平台防护等级也提出了越来越高的要求，如部分可移动平台的防护等级要求在IP45及以上。为了满足防护等级较高的可移动平台的散热需求，传统的散热结构20通常要设置多个散热风扇对不同区域的电路板进行散热，这需要占用较多的空间，导致可移动平台的整体体积较大且比较笨重，不利于可移动平台小型化的发展。
而利用本申请的散热结构20，结构紧凑且散热气流利用率高，能够减少气流产生组件200的功率，进而减小气流产生组件200的体积。既能够满足可移动平台的防护要求以及散热要求，又能够适应可移动平台小型化发展需求。
如图4所示，在一些实施例中，每条散热风道110上均设有至少一个第一安装部120。如此，利用第一安装部120将在每条散热风道110上安装第一被散热组件30，可以充分利用散热风道110对第一被散热组件30进行散热，以提高可移动平台的散热效率，提高可靠性。
参照图2及图7所示，在一些实施例中，机身10设有容纳腔11，第一安装部120设置于散热风道110的外侧壁，以使第一被散热器件设置于容纳腔11内。如此，将第一被散热器件设置于容纳腔11内，有利于提高可移动平台的防护等级，有利于减少防护配合，进一步有利于可移动平台小型化发展。
可选地，散热支架100与机身10之间密封连接，以使容纳腔11形成一个密闭空间，第一被散热器件通过第一安装部120设置于密闭空间内。如此，可以提高对第一被散热器件的防护能力，有利于提升可移动平台的防护等级。
如图7所示，在一些实施例中，散热支架100呈筒状结构，并贯穿机身10设置，以使散热风道110流经容纳腔11设置。如此，利用筒状结构的散热支架100，便于模块化贯穿机身10设置，使得散热风道110流经容纳腔11，进而能够散热结构20提高机身10的散热能力。同时也便于散热支架100与机身10密封配合，以满足防护要求。
气流产生组件200的具体实现方式可以有多种，包括无叶风扇和有叶风扇，还包括利用电机带动扰动件产生散热气流的其他变形结构，如负压发生器、正压发生器、电动充气泵、风机、空气压缩机等。
可选地，气流产生组件200包括轴流风机。如此，可以进一步提高散热效率的同 时，减小散热结构20的体积，有利于可移动平台小型化。
为了提高第一被散热组件30的散热效率，第一被散热组件30与散热风道110侧壁之间设有导热层，便于将第一被散热组件30通过导热层快速传递给散热风道110进行散热。

在一些实施例中，第一被散热组件30包括第一装配线路板。如此，可以将更多电子器件集成到电路板上，使得可移动平台的内部结构更加紧凑，有利于减少连接线路，有利于可移动平台小型化。
例如，第一被散热组件30包括电路板以及设置于电路板上的芯片，芯片与电路板之间设有环路热管或均热板，便于利用电路板进行散热，避免第一被散热组件30局部过热。
如图4所示，在一些实施例中，出风部210的出风方向与进风端111的进风方向呈钝角设置。如此，便于进行分流。特别地，与前述迎风部311结合，便于将更多的散热气流导入远离机身10底部的散热风道110内，也即第一流道，为耐热性较差的第一被散热器件提高足够的散热气流。而将其他散热气流导入靠近机身10底部的散热风道110内，也即第二流道，以提高散热气流的散热利用率。
如图4所示，在一些实施例中，散热支架100包括与至少两条散热风道110连通的安装管体180，安装管体180的一端设有进风口181，气流产生组件200设置于安装管体180内。如此，利用安装管体180安装气流产生组件200，并利用安装管体180的一端形成进风口181，便于将散热支架100安装于机身10，即可实现将散热结构20集成到机身10上，有利于提高可移动平台的组装效率。
需要说明的是，该“安装管体180”可以为“散热支架100”这一模块的其中一个零件，即与“散热支架100的其他构件”组装成一个模块，再进行模块化组装；也可以与“散热支架100的其他构件”相对独立，可分别进行安装，即可在本装置中与“散热支架100的其他构件”构成一个整体。
等同的，本申请“单元”、“组件”、“结构”、“装置”所包含的构件亦可灵活进行组合，即可根据实际进行模块化生产，作为一个独立的模块进行模块化组装；也可以分别进行组装，在本装置中构成一个模块。本申请对上述构件的划分，仅是其 中一个实施例，为了方便阅读，而不是对本申请的保护的范围的限制，只要包含了上述构件且作用相同应当理解是本申请等同的技术方案。
如图8及图9所示，在一些实施例中，散热支架100还包括设置于散热风道110内的第一散热部130，第一散热部130与第一安装部120相对设置。如此，利用第一散热部130可以提高散热风道110的散热效率。

在上述任一实施例的基础上，在一些实施例中，至少两条散热风道110沿预设方向依次排布。如此，可以利用散热风道110进行更多的第一被散热组件30的散热。同时可以根据需要，将不同耐热性能的第一被散热组件30进行分类，然后安设到预设的散热风道110上，进而可以利用分流组件300实现所需的散热气流的供给，有利于进一步利用散热气流。
一些示例性中，耐热性能越高的第一被散热组件30所对应的散热风道110的流道面积越小。如此，便于可移动平台利用散热结构20合理地排布第一被散热组件30，可以将气流产生组件200散热气流经分流组件300合理输送至各散热风道110，提高散热气流的散热利用率。
如图4所示，进一步地，示例性的，散热支架100包括沿竖直方向相邻设置的两个散热风道110，且其中一条散热风道110为第一流道，另一条散热风道110为第二流道；第一流道设置于第二流道的上方，且第一流道的流道面积大于第二流道的流道面积。如此，便于将耐热性能较好的第一被散热组件30设置于第二流道上，而耐热性能较差的第一被散热组件30设置于第一流道上，提高散热气流的散热利用率。
如图4所示，进一步地，在一些实施例中，第一流道包括出风端112，第一流道设有沿进风端111至出风端112方向间隔设置的至少两个第一安装部120。如此，在第一流道上可以进一步根据耐热性能的不同来安装至少两个第一被散热组件30，进一步提高散热气流的散热利用率。
如，至少两个第一被散热组件30设置于第一流道上，将耐热性能较差的第一被散 热组件30靠近进风端111设置，而耐热性能较好的第一被散热组件30靠近出风端112设置。

在一些实施例中，两个相邻的散热风道110中其中一条为第一流道，另一条为第二流道；迎风部311包括第一导流面301以及第二导流面302，第一导流面301靠近第一流道设置，用于将散热气流导向第一流道，第二导流面302靠近第二流道设置， 用于将散热气流导向第二流道。如此，利用第一导流面301将散热气流导入第一流道内，利用第二导流面302将散热气流导入第二流道内，有利于减少紊流，实现更加精确的导流分配效果。
在一些实施例中，导流件310包括第一导流体312以及第二导流体313，第一导流体312的一端与第二导流体313的一端相交形成迎风部311，第一导流体312的另一端以及第二导流体313的另一端分别与分隔件140固定连接。如此，利用相交设置的第一导流体312以及第二导流体313相交形成迎风部311，使得该迎风部311呈锥角状，有利于减少紊流，以实现更加精确且可靠的导流分配效果。
在上述实施例的基础上，在一些实施例中，第一导流体312的材质和第二导流体313的材质为记忆金属，且能够根据第一被散热组件30的温度变化，调整迎风部311与出风部210之间的角度。如此，利用记忆金属材料制作得到第一导流体312以及第二导流体313，将导流件310设置于相邻两个散热风道110之间，第一导流体312能够将散热气流导向靠近其设置的散热风道110内，第二导流体313能够将散热气流导向靠近其设置的散热风道110内，便于根据分流需求设置迎风部311的角度，以实现更加精确且可靠的导流分配效果。
如，当某一第一被散热组件30散热量较大，其温度较高，导致其对应的散热风道110所对应的第一导流体312或第二导流体313的温度会相对较高，进而会根据该温度变化发生变形，自动进行调整，使得迎风部311与出风部210之间的角度可调，将更多的散热气流分配给对应的散热风道110。
在一些实施例中，第一导流体312的材质和第二导流体313的材质为记忆金属，分流组件300还包括发热件320，第一导流体312和第二导流体313均设有发热件320，以调整迎风部311与出风部210之间的角度。如此，利用第一被散热组件30自带的温度检测元件或其他检测元件能够及时检测第一被散热组件30，当其温度大于预设耐热值时，其对应的散热风道110所对应的第一导流体312或第二导流体313上的发热件320可以主动发热，使导流件310根据该温度变化发生变形，自动进行迎风部311的位置调整，实现迎风部311与出风部210之间的角度调整，将更多的散热气流分配给对应的散热风道110。
在一些实施例中，分流组件300还包括传动单元330，导流件310通过传动单元330可动设置于分隔件140，以使迎风部311与出风部210之间的角度可调。如此，传动单元330也可以集成到分隔件140上，提高散热结构20的组装效率。也便于利用 传动单元330改变导流件310的位置，实现迎风部311与出风部210之间的角度调整。
在上述任一实施例的基础上，如图4、图7至图9所示，一实施例中，散热支架100包括散热壳体150、盖板160以及分隔件140，散热壳体150设有散热通槽151，盖板160设置于散热壳体150，以使散热通槽151形成散热管道，分隔件140设置于散热管道内，将散热管道分隔成两个散热风道110。如此，将分隔件140设置于散热壳体150的散热通槽151中，然后再利用散热壳体150与盖板160组合成散热管道，并利用分隔件140在散热管道上形成两个散热风道110，如第一流道以及第二流道。
可选地，散热管道的拼接处可以直接焊接密封，也可以利用防水胶圈等进行进行防水密封。
此外，散热支架100与机身10之间的连接处也可以直接焊接密封，也可以利用防水胶圈等进行进行防水密封，以提高容纳腔11的防水等级。
进一步地，利用隔热材料将被散热器件隔离在散热结构20上，减少热量进入容纳腔11中。
在一些实施例中，至少一个第一安装部120设置于盖板160；散热壳体150包括与盖板160相对设置的第一侧壁，至少一个第一安装部120设置于第一侧壁。如此，利用第一安装部120，便于将第一被散热组件30设置于盖板160上，有利于提高可移动平台组装效率。
在一些实施例中，靠近盖板160设置的散热风道110的流道面积大于远离盖板160设置的散热风道110的流道面积。也即，越靠近容纳腔11的底部设置的第一被散热组件30的耐热能力越强，越靠近容纳腔11的底部设置的散热风道110的流道面积越小。如此，可以将耐热性能较好的第一被散热组件30，如电调板设置于容纳相的底部；而将耐热性能较差的第一被散热组件30设置于盖板160上。
由于电调板主要在飞行时产热，且发热功率与飞行功耗成正比。因此单独将其布置在下侧的散热风道110，也即第二流道上，有利于根据飞行工况动态调整其风量分配。
如图10所示，在一些实施例中，散热支架100还包括支撑件170，支撑件170用于与机身10连接。如此，利用支撑件170将散热结构20集成到机身10上。同时可以散热支架100进行支撑，形成加强筋结构，可以提高机身10的强度。
如图11所示，在一些实施例中，可移动平台还包括控制装置50，控制装置50 与气流产生组件200通信连接，以控制气流产生组件200的产生散热气流。如此，利用控制装置50可以控制气流产生组件200的通断。
进一步地，在一些实施例中，控制装置50与分流组件300通信连接，以调整不同散热风道110之间的散热气流大小。如此，利用控制装置50可以控制分流组件300进行运动，以实现散热流量分配调整。
结合前述的主动分流组件300的实施例，控制装置50与发热件320或传动单元330通信连接。
更进一步地，在一些实施例中，可移动平台还包括温度检测装置60，温度检测装置60用于检测第一被散热组件30的温度信息，并将温度信息发送给控制装置50。如此，利用温度检测装置60可以主动获取第一被散热组件30的温度信息，提高反应速度，有效保证第一被散热组件30在耐热温度范围内运行，提高可靠性。
温度检测装置60的具体实现方式可以有多种，包括但不限于温度传感器等接触式温度检测装置60、红外线温度检测器等非接触式温度检测装置60。
再进一步地，如图11所示，在一些实施例中，控制装置50包括处理器以及用于存储计算机程序的存储器，处理器用于运行存储器中存储的计算机程序以实现如下的散热控制方法：
获取至少两条散热风道110的第一被散热组件30的温度信息；
当有一条散热通道对应的第一被散热组件30的温度值大于预设温度值，且有一条散热通道对应的第一被散热组件30的温度值小于预设温度值时，控制分流组件300动作，以增大进入温度值大于预设温度值的散热风道110的散热气流的流量，减小进入温度值小于预设温度值的散热风道110的散热气流的流量。
如此，控制装置利用该散热控制方法，能够结合第一被散热组件的温度的大小，控制分流组件实现散热气流的自动分配，以使第一被散热组件在各自的耐热温度范围内运行，有利于提高可移动平台的可靠性。
此外，控制分流组件动作，以实现增大进入温度值大于预设温度值的散热风道的散热气流的流量，减小进入温度值小于预设温度值的散热风道的散热气流的流量，进而在不改变气流产生组件的功率的情况下，充分利用其产生的散热气流，有利于降低散热的功耗。
存储器包括：U盘、移动硬盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、磁盘或者光盘等各种可以存储程序代码的介质。
处理器可以是微控制单元(Micro-controller Unit，MCU)、中央处理器(Central Processing Unit，CPU)或者数字信号处理器(Digital Signal Processor,DSP)等等。
预设温度值根据第一被散热组件的最大耐热温度进行设定，且其具体大小可以根据实际情况进行选择。如，比最大耐热温度小1℃、2℃等。
一些实施例中，控制装置和/或温度检测装置可以集成在第一被散热组件中。
在一些实施例中，散热结构包括两条散热风道，其中一条散热风道为第一流道，另一条散热风道为第二流道；当第一流道对应的第一被散热组件的温度值大于预设温度值，且第二流道对应的第一被散热组件的温度值小于预设温度值时，控制分流组件动作，以增大进入第一流道的散热气流的流量，减小进入第二流道的散热气流的流量；当第一流道对应的第一被散热组件的温度值小于预设温度值，且第二流道对应的第一被散热组件的温度值大于预设温度值时，控制分流组件动作，以增大进入第二流道的散热气流的流量，减小进入第一流道的散热气流的流量。如此，利用控制装置可以实现更加精确的散热气流的分流控制，以保证第一被散热组件在耐热温度范围内运行。
进一步地，一些实施例中，预设温度值包括第一温度值以及大于第一温度值的第二温度值；当第一流道对应的第一被散热组件的温度值大于第一温度值，且第二流道对应的第一被散热组件的温度值小于第二温度值时，控制分流组件动作，以增大进入第一流道的散热气流的流量，减小进入第二流道的散热气流的流量；当第一流道对应的第一被散热组件的温度值小于第一温度值，且第二流道对应的第一被散热组件的温度值大于第二温度值时，控制分流组件动作，以增大进入第二流道的散热气流的流量，减小进入第一流道的散热气流的流量。如此，可以针对在不同散热风道的第一被散热组件设置不同的耐热温度(也即第一温度值与第二温度值不同)，以充分利用散热气流进行散热，有利于降低气流产生组件的功率，进而降低可移动平台的散热功耗，提高续航能力。
在上述散热控制方法的任一实施例的基础上，一些实施例中，散热控制方法还包括：
当所有散热通道的第一被散热组件的温度均大于预设温度值时，增大气流产生 组件产生的散热气流的流量。进而通过监测散热风道上所有被散热组件的耐热温度值，若只有某一第一被动散热组件到达预设温度时，优先进行分流组件的控制，利用分流组件进行散热气流控制，以降低该第一被动散热组件。如只存在第一流道或者第二流道的散热气流不足，则优先调整分流组件。而当所有散热通道的第一被散热组件的温度均大于预设温度值则增大气流产生组件产生的散热气流的流量，也即调整气流产生组件转速。具体可为，调整轴流风机的转速。如此，最终实现在各种工况下，气流产生组件优先以最低转速保证所有被散热器件均保持在有一点余量下进行工作，实现最佳功耗和最低噪声控制。
如图12所示，在本申请的实施例中，一种散热控制方法，包括：
获取至少两条散热风道的第一被散热组件的温度信息；
当有一条散热通道对应的第一被散热组件的温度值大于预设温度值，且有一条散热通道对应的第一被散热组件的温度值小于预设温度值时，控制分流组件动作，以增大进入温度值大于预设温度值的散热风道的散热气流的流量，减小进入温度值小于预设温度值的散热风道的散热气流的流量。
如此，控制装置利用该散热控制方法，能够结合第一被散热组件的温度的大小，控制分流组件实现散热气流的自动分配，以使第一被散热组件在各自的耐热温度范围内运行，有利于提高可移动平台的可靠性。
此外，控制分流组件动作，以实现增大进入温度值大于预设温度值的散热风道的散热气流的流量，减小进入温度值小于预设温度值的散热风道的散热气流的流量，进而在不改变气流产生组件的功率的情况下，充分利用其产生的散热气流，有利于降低散热的功耗。
一些实施例中，散热控制方法可以应用于可移动平台中，也可以应用于散热结构中。也即，在散热结构中设置子控制模块，以及温度检测装置，实现对分流组件的控制。
在一些实施例中，散热结构包括两条散热风道，其中一条散热风道为第一流道，另一条散热风道为第二流道；当第一流道对应的第一被散热组件的温度值大于预设温度值，且第二流道对应的第一被散热组件的温度值小于预设温度值时，控制分流组件动作，以增大进入第一流道的散热气流的流量，减小进入第二流道的散热气流的流量；当第一流道对应的第一被散热组件的温度值小于预设温度值，且第二流道对应的第一 被散热组件的温度值大于预设温度值时，控制分流组件动作，以增大进入第二流道的散热气流的流量，减小进入第一流道的散热气流的流量。如此，利用控制装置可以实现更加精确的散热气流的分流控制，以保证第一被散热组件在耐热温度范围内运行。
进一步地，在一些实施例中，预设温度值包括第一温度值以及大于第一温度值的第二温度值；当第一流道对应的第一被散热组件的温度值大于第一温度值，且第二流道对应的第一被散热组件的温度值小于第二温度值时，控制分流组件动作，以增大进入第一流道的散热气流的流量，减小进入第二流道的散热气流的流量；当第一流道对应的第一被散热组件的温度值小于第一温度值，且第二流道对应的第一被散热组件的温度值大于第二温度值时，控制分流组件动作，以增大进入第二流道的散热气流的流量，减小进入第一流道的散热气流的流量。如此，可以针对在不同散热风道的第一被散热组件设置不同的耐热温度(也即第一温度值与第二温度值不同)，以充分利用散热气流进行散热，有利于降低气流产生组件的功率，进而降低可移动平台的散热功耗，提高续航能力。
在上述散热控制方法的任一实施例的基础上，一些实施例中，散热控制方法还包括：
当所有散热通道的第一被散热组件的温度均大于预设温度值时，增大气流产生组件产生的散热气流的流量。进而通过监测散热风道上所有被散热组件的耐热温度值，若只有某一第一被动散热组件到达预设温度时，优先进行分流组件的控制，利用分流组件进行散热气流控制，以降低该第一被动散热组件。如只存在第一流道或者第二流道的散热气流不足，则优先调整分流组件。而当所有散热通道的第一被散热组件的温度均大于预设温度值则增大气流产生组件产生的散热气流的流量，也即调整气流产生组件转速。具体可为，调整轴流风机的转速。如此，最终实现在各种工况下，气流产生组件优先以最低转速保证所有被散热器件均保持在有一点余量下进行工作，实现最佳功耗和最低噪声控制。
