下面结合附图，对本发明的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互结合。
图1为本发明散热系统的结构示意图；图2为本发明散热系统的结构示意图；图3为本发明散热系统的爆炸图。
参照图1至图3，本实施例提供一种散热系统，包括：散热器100和散热风扇200；散热风扇200安装在散热器100的第一端；散热器100包括对应多个不同温度的发热元件300的多个散热区域110，用于对多个不同温度的发热元件300分别进行散热。
本实施例中的散热系统包括散热器100和散热风扇200，散热风扇200可以是现有的轴流风扇结构。一般的摄影摄像设备内部设置有录音装置，风扇产生的噪声会影响到录音效果，优选地，散热风扇200可以为静音风扇，避免产生噪声影响录音装置的录音效果。散热风扇200安装在散热器100的第一端，散热器100可以位于散热风扇200的出风侧，散热风扇200向散热器100内吹入气流，使气流从散热器100的第二端流出；散热器100也可以 位于散热风扇200的进风侧，散热风扇200将散热器100的气流吸出来，气流从散热器100的第二端进入，在散热风扇200抽吸作用下，排出散热器100，实现散热。散热风扇200可以设置一个，安装在散热器100的第一端；或者，为了增加散热风量，散热风扇200还可以设置多个，例如，两个、三个等，多个散热风扇200按照预设方向并列设置，本实施例对散热风扇的数量及排列方式不做限定。
本实施例中的散热器100包括多个散热区域110，多个发热元件300设置在不同的散热区域110内分别进行散热，避免多个发热元件300之间存在热耦合，影响散热效果。该多个发热元件300可为不同温度或具有不同发热效率。例如，在摄影摄像设备中，发热元件300至少包括主控板、供电板、SSD卡(固态硬盘卡)，主控板和供电板的温度要在许用工作温度范围内，SSD卡需要满足外壳温度要求，保证其在热插拔时的触感温度，其温度要求更高。将不同要求的发热元件300，例如，主控板、供电板、SSD卡等，设置在不同的散热区域110进行散热，避免对不同发热元件散热时的热耦合，不但实现良好的散热效果，并且，若是不同温度的发热元件，则进一步避免不同温度要求的发热元件300之间进行热耦合而影响散热效果。
本实施例散热系统，通过在散热器内设置多个散热区域，使得发热元件安装在不同的散热区域内，通过散热风扇对该多个发热元件进行散热，有效避免不同发热元件之间进行热耦合，提高散热效果，保证散热效率。且对于温度不同的发热元件，通过多区域散热，可针对不同温度设置不同的散热结构，避免热耦合且提高散热效率。
在一些可选地实施例中，散热器100内设置有隔热板，以将散热器100分隔成多个散热区域以便对多个不同温度的发热元件300分别进行散热。散热器100可以设置一个隔热板，将散热器100分隔成两个散热区域110，两个散热区域110内设置不同温度要求的发热元件300。当然，散热器100还可以设置多个隔热板，多个隔热板按照预设方向平行间隔设置，或者，多个隔热板交叉设置等，将散热器100分隔成多个散热区域110。隔热板可以是现有隔热材质的隔热板，本发明对此不做限定。
在另一些可选地实施例中，散热器100包括散热壳体120以及设置在散热壳体120内部的散热鳍片130；散热壳体120包括相对设置的第一侧板121 和第二侧板122，散热鳍片130的第一端与第一侧板121固定连接，散热鳍片130的第二端与第二侧板122固定连接；散热鳍片130为多个，沿第一预设方向间隔设置；相邻散热鳍片130之间的间隙形成散热风道131；散热鳍片130上开设有隔热间隙，以将散热鳍片130至少分隔成靠近第一侧板121的第一散热区域111和靠近第二侧板122的第二散热区域112。可以理解，所述散热壳体120也可包括多个侧板，且所述散热鳍片130可以分隔成对应所述多个侧板的多个散热区域，每个区域中散热鳍片130的一端固定于对应的侧板上。所述散热壳体120可以为板状结构，也可为框体或其他结构。
具体参照图2，散热器100包括散热壳体120以及散热鳍片130，散热鳍片130设置在散热壳体120内部。其中，散热壳体120可以为长方壳体形状，其中相对的两个面分别为进气端和出气端，散热壳体120也可以是圆筒结构，其相对的上圆面和下圆面分别为进气端和出气端，散热壳体120也可以是其他形状。
优选地，散热壳体120包括相对设置的第一侧板121和第二侧板122，且第一侧板121和第二侧板122平行设置。散热鳍片130的第一端与第一侧板121固定连接，散热鳍片130的第二端与第二侧板122固定连接。并且散热鳍片130为多个，沿第一预设方向平行、均匀间隔设置，相邻的散热鳍片130之间的间隙形成散热风道131。其中，第一预设方向与第一侧板121和第二侧板122之间连线方向垂直。散热鳍片130可以与第一侧板121垂直设置，散热鳍片130也可以相对第一侧板121朝向一侧倾斜设置。散热鳍片130可以是平板结构，形成的散热风道131为直风道，有利于气流的流通；或者，散热鳍片130为弯折平板，即平板弯折成预设角度的板结构，形成的散热风道131为弯折风道，增大散热鳍片130的散热面积。
散热鳍片130上开设有隔热间隙，即，将散热鳍片130在第一侧板121和第二侧板122之间的某个位置截断，形成隔热间隙，该隔热间隙与散热风道131垂直，利用空气进行隔热。优选地，隔热间隙可以与第一侧板121平行。隔热间隙将散热风道131至少分隔成靠近第一侧板121的一段以及靠近第二侧板122的一段，至少形成靠近第一侧板121的第一散热区域111，以及靠近第二侧板122的第二散热区域112。第一散热区域111以及第二散热区域112的散热鳍片130的散热面积可以相同，例如，第一散热区域111内 散热鳍片130与第二散热区域112内的散热鳍片130沿散热风道131方向的长度相同，且，隔热间隙设置在第一侧板121和第二侧板122的中间位置。
可选地，对应不同温度的发热元件300，第一散热区域111内散热鳍片130的散热面积与第二散热区域112内的散热鳍片130的散热面积不同，以针对不同温度要求的发热元件进行散热。第一散热区域111和第二散热区域112对不同温度的发热元件300分别进行散热。一方面，第一散热区域111内散热鳍片130与第二散热区域112内的散热鳍片130沿散热风道131方向的长度不同，通过设置不同长度的散热鳍片130使得第一散热区域111和第二散热区域112具有不同的散热效率，以对不同的温度要求的发热元件进行散热。
和/或，
另一方面，隔热间隙与第一侧板121的距离和隔热间隙与第二侧板122的距离不相同，通过将隔热间隙设置在第一侧板121和第二侧板122之间不同的位置，使得第一散热区域111和第二散热区域112具有不同的散热效率，以对不同的温度要求的发热元件进行散热。
和/或，
再一方面，第一散热区域111的多个散热鳍片130之间的间隔距离和第二散热区域112的多个散热鳍片130之间的间隔距离不同，从而实现不同的散热效率。
继续参照图2，散热壳体120还包括相对设置的第三侧板123以及第四侧板124，第一侧板121、第三侧板123、第二侧板122以及第四侧板124依次连接形成长方筒形结构，散热鳍片130设置在长方筒形结构的内部。
可选地，在第三侧板123的内侧面上还设置有多个散热鳍片130，多个散热鳍片130沿第二预设方向平行、均匀间隔设置，相邻的散热鳍片130之间的间隙形成散热风道131。其中，第二预设方向与第一预设方向垂直。在第三侧板123上设置的多个散热鳍片130形成第三散热区域113。第三散热区域113内的散热鳍片130可以垂直于第三侧板123设置，也可以朝向第一侧板121或者第二侧板122倾斜设置。第三散热区域113内的散热鳍片130远离第三侧板123的一端与第一散热区域111和第二散热区域112内的靠近第三侧板123的散热鳍片130具有隔热间隙，当然，隔热间隙内还可以设置 隔热板，防止第一散热区域111、第二散热区域112与第三散热区域113内的发热元件300之间发生热耦合，影响散热效率。
可选地，在第四侧板124的内侧面上还设置有多个散热鳍片130，多个散热鳍片130沿第二预设方向平行、均匀间隔设置，相邻的散热鳍片130之间的间隙形成散热风道131。其中，第二预设方向与第一预设方向垂直。在第四侧板124上设置的多个散热鳍片130形成第四散热区域114。第四散热区域114内的散热鳍片130可以垂直于第四侧板124设置，也可以朝向第一侧板121或者第二侧板122倾斜设置。第四散热区域114内的散热鳍片130远离第四侧板124的一端与第一散热区域111和第二散热区域112内的靠近第四侧板124的散热鳍片130具有隔热间隙，当然，隔热间隙内还可以设置隔热板，防止第一散热区域111、第二散热区域112与第四散热区域114内的发热元件300之间发生热耦合，影响散热效率。
需要说明的是，第三散热区域113和第四散热区域114内的散热鳍片130的形状以及散热风道131与第一散热区域111和第二散热区域112的散热鳍片130的形状以及散热风道131类似，在此不再赘述。
在上述实施例的基础上，本实施例散热系统还包括散热板；散热板的第一侧面与第一侧板121固定连接，散热板的第二侧面用于安装发热元件300。发热元件300可以是主控板、供电板等，发热元件300可以通过螺钉等紧固件与散热板连接，或者，发热元件300也可以粘接在散热板的第二侧面等。可选地，散热板的第二侧面与发热元件300之间设置有导热凝胶层，有利于传导散热。散热板可以是散热铝板、散热铜板等，本发明不做限定。当然，散热板可以设置多个，分别设置在第二侧板122、第三侧板123以及第四侧板124上。
优选地，散热板与散热壳体120的第一侧板121为一体成型的一体件，即第一侧板121直接作为散热板，其外侧面安装发热元件300，既可以减小散热系统的体积，还可以提高散热效率。第二侧板122、第三侧板123以及第四侧板124都可以分别作为散热板对不同的发热元件300进行散热。
由于摄影摄像设备中安装空间有限，一些发热元件可能距离散热系统有一定的距离，在一些实施例中，散热系统还包括导热管；散热板和第一侧板121之间具有间隔；导热管的第一端与散热板的第一侧面固定连接，导热管 的第二端插入到第二散热区域112内，通过导热管将发热元件散发的热量引导至散热板以进行散热。导热管也可以插入到第一散热区域111、第三散热区域113或者第四散热区域114中。本发明对此不做具体限定，本领域技术人员可以根据摄影摄像设备内各元件的安装位置进行设置。优选地，导热管在散热区域内的延伸方向与散热风道131相交，例如导热管与散热风道131垂直，保证每个散热风道131内的气流经过导热管，保证散热效率。
参照图1至图3，本实施例散热系统还包括：散热支撑组件140；散热支撑组件140的第一侧面与第二侧板122固定连接；散热支撑组件140内设置有插槽141，用于安装可插拔发热元件。本实施例散热系统通过将可插拔发热元件设置在散热支撑组件140的插槽141内，在实现其安装的同时，有利于其散热。散热支撑组件140可以通过螺钉等紧固件与第二侧板122固定连接，散热支撑组件140的第一侧面还可以与第二侧板122一体成型。当然，散热支撑组件140也可以与第三侧板123或者第四侧板124固定连接。例如，散热支撑组件140可以与第三侧板123固定连接，如图2所示，但本发明不以此为限。
可插拔发热元件可以是SSD卡，SSD卡不仅需要满足其许用工作温度，还需要满足插拔时的接触温度，所以，其散热要求相对较高。可选地，第二散热区域112内散热鳍片130的散热面积大于第一散热区域111内的散热鳍片的散热面积。具体地，第二散热区域112内散热鳍片130沿散热风道131方向的长度大于第一散热区域111内的散热鳍片130沿散热风道131方向的长度；和/或，隔热间隙与第二侧板122的距离大于隔热间隙与第一侧板121的距离，使得不同散热区域内散热效率不同，实现对不同温度发热元件进行散热。
需要说明的是，在本发明中，各个散热区域，例如第一散热区域111、第二散热区域112、第三散热区域113以及第四散热区域114内的散热鳍片130的散热面积根据其实际散热的发热元件进行设定，其中某个散热区域的发热元件要求，其内的散热鳍片130的散热面积相对较大。
在另外一些可实施例中，散热板与散热壳体120的第一侧板121之间具有间隔，散热板通过导热管对发热元件300进行散热，此时，散热系统的散热支撑组件140还可以位于所述间隔内、且散热支撑组件140与第一侧板121 固定连接；散热支撑组件140内设置有插槽141，用于安装可插拔发热元件。在本实施例中发热元件300都位于第一侧板121的一侧。此时，第二散热区域112通过导热管，对散热板上的发热元件300，例如：主控板310、供电板等，进行散热；第一散热区域111通过散热支撑组件对可插拔发热元件，例如：SSD卡等，进行散热。并且，在这种情况下，第一散热区域111内的散热鳍片的散热面积大于第二散热区域112内散热鳍片130的散热面积。
可以理解的是，导热管、散热板以及散热支撑组件可以分别设置在散热壳体120不同的侧板上，本领域技术人员可以根据摄影摄像设备内发热元件具体的安装位置进行设置。例如，参照图2，主控板310可以分别设置在第一侧板121、第二侧板122以及第四侧板124上，SSD卡320设置在第三侧板123上。
图4为本发明散热系统的第一支撑板的一实施例的结构示意图；图5为图4中第一支撑板的侧视图；图6为图4中第一支撑板的分解示意图。
参照图4至图6，散热支撑组件140包括第一支撑板142和第二支撑板；第一支撑板142和第二支撑板之间形成插槽141；第一支撑板142上设置有第一弹性件1421；和/或，第二支撑板上设置有第二弹性件。
散热支撑组件140还包括连接第一支撑板142和第二支撑板的两个侧板，围成一个筒体结构，筒体结构的一端还设置有底板，可插拔发热元件从开口端插入。第一弹性件1421设置在第一支撑板142靠近第二支撑板的一侧，且凸出于第一支撑板142。优选地，第一弹性件1421为多个，沿第一支撑板142的长度方向间隔设置，且多个第一弹性件1421沿第一支撑板142的宽度方向间隔设置，例如，第一支撑板142上设置有四个第一弹性件1421，沿第一支撑板142的长度方向设置两个，且沿第一支撑板142的宽度方向设置两个，形成一个四边形结构，以更好的支撑可插拔发热元件。
第一支撑板上142上还设置有支撑条1422，用于进一步支撑可插拔发热元件。优选地，支撑条1422为多个，与多个第一弹性件1421间隔设置。例如，第一支撑板142上设置有六个支撑条，其中三个支撑条1422沿第一支撑板142的长度方向、与第一弹性件1421间隔设置，且沿第一支撑板142的宽度方向设置两个支撑条1422。支撑条1422的凸出于第一支撑板142的高度小于第一弹性件1421的未压缩时的高度。
第一支撑板142的插入端设有引导框1423，引导可插拔发热元件插入。
进一步地，第一支撑板142远离第二支撑板的一侧固定在壳体外板410上，例如第一支撑板142通过螺钉固定在壳体外板410上，壳体外板410固定连接在机体400上。
第二支撑板上靠近第一支撑板142的侧面可以设置有第二弹性件，第二弹性件的数量及设置方式与第一弹性件1421相同，在此不再赘述。
第二支撑板可以为单独的板件，与散热壳体120的侧板固定连接。优选地，第二支撑板与散热壳体120的侧板为一体成型的一体件。
为了提高散热效果，第一支撑板142朝向第二支撑板的侧面设置有导热胶层，以实现与可插拔发热元件的良好接触，防止多次插拔对可插拔发热元件造成刮擦磨损。导热胶层可以粘贴在第一支撑板142朝向第二支撑板的侧面上。
可选地，第二支撑板朝向第一支撑板142的侧面也可以设置有导热胶层；或者，第一支撑板142与壳体外板410接触的侧面也设置有导热胶层。
本实施例通过在散热支撑组件的第一支撑板上设置第一弹性件，不仅能够保证可插拔发热元件能够顺利插拔，而且保证可插拔发热元件与第一支撑板之间良好的接触散热。
优选地，散热风扇200为静音风扇，维持较低的噪声水平，使得摄影摄像设备具有较好的录音效果。
优选地，散热风扇200为多个，沿第一预设方向间隔设置，提供足够的风量，提高散热能力。
优选地，散热风道131为直风道，散热风道131没有折弯，没有明显的截面变化，保证散热风道131最低阻力。在保证散热风道最低阻力的同时，即可保证散热风扇200在低阻抗高风量的最佳工作点工作。
可选地，本实施例中的散热器100还包括围绕散热区域110设置的支撑框，支撑框围设形成风腔。支撑框可以是单独设置的框架结构，围绕散热区域110设置；或者，支撑框和散热器100的散热壳体120为一体成型的一体件，例如，第一侧板121、第三侧板123、第二侧板122以及第四侧板124的同一端形成支撑框，支撑框围设形成风腔。散热风扇200与支撑框固定连接，散热风扇200可以向风腔内吹风，风腔内的气流流向散热风道131；散热风 扇200也可以从风腔内吸风，散热风道131内的气流经过风腔向外排出。
散热器100位于散热风扇200的出风口侧；支撑框的端部连接于散热风扇200的一端，且散热风扇200的出风气流均从风腔内流向散热区域110。可选地，支撑框为单独设置的框架结构，其端部与散热风扇200连接，散热风扇200与支撑框可以卡接、螺接等，在此不做限定。支撑框围设在散热风扇200的外侧，使得散热风扇200的出风气流均从风腔内流向散热区域110，有效避免从散热器100内流出的气体再次进入散热器100内。
进一步地，支撑框包括多个依次连接的侧板；散热器100包括分别设置于多个侧板内侧的多个散热区域100，发热元件300设置于多个侧板中的至少一个侧板的外侧。支撑框包括的多个侧板可以是单独设置的侧板，也可以是与散热壳体120的各个侧板一体成型的侧板。多个侧板的内侧设置有散热鳍片130和隔热间隙，形成多个散热区域100，发热元件300设置于多个侧板中的至少一个侧板的外侧。
本实施例提供一种摄影摄像设备，包括外壳以及设置在外壳内部的散热系统；散热系统包括：散热器100和散热风扇200；散热风扇200安装在散热器100的第一端；散热器100包括对应多个发热元件300的多个散热区域110，用于对多个发热元件300分别进行散热；外壳设置有进风口和出风口；进风口和散热风扇200之间设置有进风风道，出风口和散热器100的第二端之间设置有出风风道。
摄影摄像设备的外壳包括多个壳体外板410，散热系统设置在多个壳体外板410围成的外壳内部。
其中，本实施例中的散热系统的具体形状结构、工作原理以及实现效果与上述实施例中的散热系统的具体形状结构、工作原理以及实现效果相同，具体可参考上述陈述内容，在此不再赘述。
本实施例摄影摄像设备，通过散热系统实现对不同温度的发热元件的散热，具体地，在散热器内设置多个散热区域，将不同温度的发热元件安装在不同的散热区域内，通过散热风扇对不同温度的发热元件进行散热，有效避免不同温度的发热元件之间进行热耦合，提高散热效果，保证散热效率。
在上述实施例的基础上，摄影摄像设备至少包括主控板、供电板；散热器包括围绕散热区域设置的支撑框，支撑框包括多个侧板；多个散热区域分 别设置于多个侧板的内侧，主控板、供电板设置于多个侧板中的至少一个侧板的外侧。
进一步地，摄影摄像设备还包括SSD卡插槽，插槽设置于多个侧板中剩余至少一个侧板的外侧。
本实施例摄影摄像设备，通过将主控板、供电板以及SSD卡设置在不同的侧板的外侧，分别进行散热，有效避免主控板、供电板以及SSD卡之间进行热耦合，提高散热效果，保证散热效率。
图7为本发明摄影摄像设备的结构示意图；图8为图7中射频模块和电池的分解示意图。
摄影摄像设备通常包括多个电子元件，多个电子元件设置在散热系统的进风口侧，并且多个电子元件在进风口侧形成进风通道450。由于散热风扇出风口侧的散热效率高于进风口侧的散热效率，故将发热量高的电子元件设置于散热风扇的出风口侧，发热量低的电子元件设置于散热风扇的进风口侧。多个电子元件可以包括电池模块420和射频模块430等
更进一步地，参照图7和图8，摄影摄像设备还包括电池模块以及射频模块。机体400的外壳上设置有进风口440，射频模块430设置在远离进风口440一侧，电池模块420设置在进风口440和射频模块430的外侧，在进风口440和射频模块430形成散热空腔，气体从各个方向经由散热风腔进入散热系统内部，流通的气流可以对电池模块420和射频模块430进行有效散热。
具体地，电池模块420和射频模块430设置于摄影摄像设备的外壳上，且射频模块430、电池模块420及外壳之间形成进风通道450。射频模块430靠近该进风通道450的一侧设置多个鳍片，便于进风口的气流的流动。
可以理解，该进风口侧也可以设置其他电子元件，不限于电池模块420和射频模块430。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
