技术领域
本发明实施例涉及电子设备技术领域，尤其涉及一种电器。
背景技术
音箱是整个音响系统的终端，其作用是将音频电能转换成相应的声能，并把它辐射到空间去。音箱的性能高低对一个音响系统的放音质量是起着关键作用。
声吧(soundbar)和智能声吧(smart soundbar)都是长条形音箱，主要用于搭配液晶电视等超薄型视频设备。如图1所示，现有的长条形音箱包括长条形箱体10，设置于长条形箱体内的集成电路板20和扬声器30。为了实现集成电路板的散热，需要在长条形箱体10上设置散热孔。随着消费者对长条形音箱外观的要求的不断提高，在长条形箱体10上设置散热孔的位置和数量越来越受到限制。因此，现有的长条形音箱存在其内集成电路板散热不足的问题；同理，其他的电器也可能存在散热不足的问题。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的一个实施例的电器，如图2所示，包括：
壳体100，壳体100具有连通壳体内外的通孔；
设置在壳体内的集成电路板210和用于为集成电路板散热的内部散热件220；
设置在壳体外的导热材料制成的外部散热件300；
导热材料制成的导热连接件400，导热连接件400通过通孔分别与壳体内的内部散热件220和壳体外的外部散热件300连接。
本发明实施例的电器，包括壳体，设置在壳体内的集成电路板和内部散热件，设置在壳体外的导热材料制成的外部散热件及导热材料制成的导热连接件，且壳体且有连通壳体内外的通孔；导热连接件在通孔处将壳体内的内部散热件和壳体外的外部散热件连接。这样，对集成电路板进行的散热不仅通过位于壳体内的内部散热件的进行，同时，通过位于壳体外的外部散热件进行；不仅增大了散热面积，同时，通过在壳体外的外部散热件进行散热，大大提高了散热效率更高。本发明实施例的电器，通过简单的结构，增大了散热面积，提高了散热效率，解决了现有的电器散热不足的技术问题。
具体的，如图2所示，外部散热件300固定在壳体100的底壁的外表面， 通孔贯穿壳体的底壁，外部散热件300还可以复用用于装饰电器或支撑壳体。
根据电器可以设置外部散热件的位置，设置通孔的位置；上述设置方式，通孔和外部散热件之间的距离较小，便于导热连接件连接，同时，电器的结构更加简单。
更进一步的，如图2所示，内部散热件220固定在集成电路板与壳体的底壁相对的一面。
根据外部散热件和通孔的位置，设置内部散热件的位置；上述设置方式，内部散热件和通孔之间的距离较小，便于导热连接件连接，同时，电器的结构更加简单。
更进一步的，如图2所示，通孔设置在内部散热件220的正下方。这样的设置方式，内部散热件，通孔和外部散热件之间的距离都较小，便于导热连接件连接，电器的结构非常简单。与之相配合，导热连接件的结构也非常的简单，导热连接件是螺栓，内部散热件和外部散热件分别设置有螺孔，在壳体的通孔处通过螺栓和螺孔将内部散热件和外部散热件连接。这样，通过设置内部散热件和通孔的位置，可以实现用结构简单的螺栓即可将内部散热件和外部散热件在通孔处连接，大大简化了电器的结构。
考虑到外部散热件设置的位置可能是有多种，外部散热件可能设置在壳体的侧壁的外表面，通孔穿壳体的侧壁；外部散热件还可能设置在壳体的顶壁的外表面，通孔穿壳体的顶壁。
把壳体设置外部散热件的侧壁或顶壁或侧壁定义为固定壁，综上，只要外部散热件设置在壳体的固定壁的外表面，通孔贯穿壳体的固定壁即可。这样的设置方式，通孔和外部散热件之间的距离较小，便于导热连接件连接，同时，电器的结构更加简单。
更进一步的，内部散热件固定在集成电路板与壳体的固定壁相对的一面。这样的设置方式，内部散热件和通孔之间的距离较小，便于导热连接件连接，同时，电器的结构更加简单。
更进一步的，通孔设置在固定壁与内部散热件正对的位置。这样的设置方式，内部散热件，通孔和外部散热件之间的距离都较小，便于导热连接件连接，电器的结构非常简单。与之相配合，导热连接件的结构也非常的简单，导热连接件是螺栓，内部散热件和外部散热件分别设置有螺孔，在壳体的通孔处通过螺栓和螺孔将内部散热件和外部散热件连接。这样，通过设置内部 散热件和通孔的位置，可以实现用结构简单的螺栓即可将内部散热件和外部散热件在通孔处连接，大大简化了电器的结构。
更进一步的，电器的壳体还可以在不影响电器美观的位置，设置散热孔。这样，可以进一步提高散热效率。
为了提高导热连接件的导热效率，导热连接件采用导热连接件是金属材料制成的导热连接件，外部散热件是金属材料制成的外部散热件；可选地，可以是铜或铝材料制成的导热连接件和外部散热件。选择导热越好的材料，越能提高导热连接件的导热效率，提高外部散热件的散热效率
由于导热连接件和内部散热件，外部散热件的连接是面积较小的连接，因此可以通过增加导热连接件的数量，增大导热连接件将与内部散热件，外部散热件连接的面积，进而提高散热的效率。
具体的，电器可以是音箱，也可以是其他电器。只要是需要散热较好的电器，都可以采用本发明实施例的电器的结构。
以上所描述的装置实施例仅仅是示意性的，其中作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部模块来实现本实施例方案的目的。本领域普通技术人员在不付出创造性的劳动的情况下，即可以理解并实施。
最后应说明的是：以上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精神和范围。
