本申请针对传统Mini-LED或Micro-LED显示器散热不佳，影响显示器性能的技术问题，本实施例能够解决该缺陷。
以下请结合具体实施例对本申请的显示装置进行详细描述。
实施例一
请参照图1所示，为本申请实施例一提供的显示装置的结构示意图。所述显示装置包括：显示模组1和散热模组2，所述显示模组1位于所述散热模组2的一侧；所述散热模组2用于对所述显示模组1进行散热。所述散热模组2包括平行于所述显示模组1设置的第一散热板21和第二散热板22，所述第一散热板21和所述第二散热板22组合后形成两端开口的空腔结构。所述散热模组2的一侧侧面具有进风口201，相对另一侧侧面具有出风口202，所述空腔形成散热风道。
其中，所述显示模组1具有显示面与背面，所述显示面设置若干点阵排列的Mini-LED发光单元或Micro-LED发光单元，所述背面与所述散热模组2贴合。所述显示模组1工作时所产生的热量会通过所述显示模组1的背面传导至所述散热模组2上，再经由所述散热风道将热量排出。
为了利于热传导进行散热，所述显示模组1与所述散热模组2之间通过导热胶粘合，所述导热胶为导热性能较好的胶材，具体材料不做限定。
进一步的，所述导热胶中均匀的掺杂有金属粒子，由于金属具有良好的导热性能，因此可以进一步增强所述导热胶的热传导性能，使所述显示模组1一侧的热量快速的传导至所述散热模组2上。
进一步的，为了增强所述散热模组2的散热性能，所述散热模组2的材料为金属材料，例如所述第一散热板21和所述第二散热板22可以采用铝合金板等。
在一种实施例中，可以通过模压等方式一体化成型所述第一散热板21和所述第二散热板22，所述第一散热板21和所述第二散热板22为一体式结构可以简化制程。
在一种实施例中，所述进风口201以及所述出风口202的的形状还可以设置为椭圆形、圆形、三角形和矩形的其中之一或者组合，所述进风口201以及所述出风口202的位置也可以根据所述显示模组1的实际散热需求而设置。
如图1所示，在所述散热模组2的下部设置有进风口201，在所述散热模组2的上部设置有出风口202，所述散热模组2的内部中空设计形成散热风道，从而在所述散热模组2的内部形成一烟囱结构。由于所述显示模组1的大部分热量朝一个方向进行散发，即所述显示模组1的热量主要通过背面散发，从而使得所述显示模组1的大部分热量散发到所述散热模组2上以及所述散热模组2的内部，所述散热模组2内部温度高的空气，密度减小而上升，并从上部出风口202排出，这时会在低密度空气原来的地方形成负压区，于是所述散热模组2外部温度比较低而密度比重大的新鲜空气从所述散热模组2下部的进风口201被吸入所述散热风道。由此，在烟囱结构的作用下，热量易于被热空气以对流方法迅速带走。这样，达到了加快所述显示模组1散热的技术效果。
为了进一步实现更好的散热效果，本实施例在所述第一散热板21面向所述第二散热板22的一侧表面设置有交错分布的散热翅23，所述散热翅23将所述散热风道分隔成多个散热子风道。
如图2所示，为本申请实施例一提供的第一散热板的结构示意图。所述第一散热板21上的所述散热翅23可以与所述第一散热板的本体一体成型，或者所述散热翅23也可以单独安装在所述第一散热板21上。相邻两行和/或相邻两列的所述散热翅23交错分布，使自下而上运动的空气可以从相邻两所述散热翅23之间的间隙进入多个散热子风道中，然后在浮力的作用下继续向上运动。所述散热翅23可以起到分流作用，使得热空气在散热风道中分布均匀，从而延缓了热边界层的形成。所述散热翅23的设置增加了散热风道中流动空气的扰动，热空气在散热风道中流动状态由单向变为多向，使所述散热翅23之间的空气流速提高，进一步增强了所述散热模组的散热性能。
进一步的，所述散热翅23倾斜于所述第一散热板21表面设置，所述散热翅23与所述第一散热板21表面之间的夹角为10°-80°。并且，所述散热翅23朝向所述出风口202一侧倾斜。
由于所述散热翅23朝向所述出风口202一侧倾斜设计，因此可以减小空气在所述散热风道中流动的阻力，有助于散热风道中的空气与外界空气对流。
进一步的，所述散热翅23的截面形状为圆形、三角形、矩形中的一种。
进一步的，所述散热翅23在垂直于所述第二散热板22的方向上与所述第二散热板22之间具有预设距离。从而既能够实现所述散热翅23的分流作用及空气扰动作用，又由于空气在散热风道中流动的阻力进一步减小，因此有利于所述散热模组2的散热性能。
在一种实施例中，所述散热翅23在所述第一散热板21上的分布密度由所述第一散热板21的中间区域向四周逐渐减小。如此，所述第一散热板21的中间区域的所述散热翅23可以很好的将热量向四周分流，有利于所述第一散热板21的中间区域的热量疏导，所述第一散热板21四周区域的所述散热翅23的密度相对较低，空气在散热风道中流动的阻力相对较小，可以快速的将散热风道中的热量带走。
本申请的显示装置中散热模组的散热效率受外界环境输入热量和显示模组发热升温影响，当输入热量越大或升温越高，烟囱效应就越强，散热效果随之会更好。本申请通过在显示模组背后设计特殊的散热风道，无需专门从外界输入动力能源，利用气体受热膨胀密度减小自然向上流动的烟囱效应，再通过散热翅的设计强化空气对流实现散热，无需外部输入电能，节省能耗。
实施例二
如图3所示，为本申请实施例二提供的显示装置的结构示意图。本实施例与上述实施例一的显示装置的结构相同/相似，区别在于：本实施例的显示装置为双面屏显示装置，可以实现双面显示，即所述显示模组包括贴合于所述第一散热板21上的第一显示模组11以及贴合于所述第二散热板22上的第二显示模组12。
所述第一显示模组11以及所述第二显示模组12的显示面设置若干点阵排列的Mini-LED发光单元或Micro-LED发光单元，当然，所述第一显示模组11以及所述第二显示模组12也可以为其他类型的显示模组，此处不做限制。
本实施例由于在两个显示模组之间设置具有烟囱效应的散热模组，因此，可以有效解决显示模组散热不佳的问题，从而提升显示模组的显示效果及使用寿命。
本申请的显示装置通过在显示模组的一侧设置具有烟囱效应的散热模组，并且散热模组内部再配合交错分布的散热翅，能够大大提升散热性能，解决传统Mini-LED或Micro-LED显示器散热不佳，影响显示器性能的问题。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
