Description

轻薄化的显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种轻薄化的显示装置。
背景技术
由于液晶本身并不会发光，因此背光模块可谓为液晶显示器(Liquid Crystal Display，LCD)面板的关键零组件，其主要功能便在供应亮度充分及分布均匀的光源，以使LCD面板能够正常显示影像。而随着LCD面板已广泛应用于众多具成长潜力的电子产品，如监视器(Monitor)、笔记型电脑、数字相机、投影机等等，背光模块及其相关零组件的需求也持续成长中。一般而言，背光模块可根据光源所在位置，分成光源产生自显示面板正下方的直下式(Direct-type)背光模块与光源来自显示面板侧边附近的侧光式(Edge-type)背光模块两种设计。而其中由于侧光式背光模块将光源产生器设于显示面板的侧边，因此可缩小液晶显示器的体积与制造成本，而应用于小型的电器产品。
现有的背光模块的主要散热方式是将热量传导至背板上，利用背板本身与外界接触的表面积将热量散逸至环境中。然而，上述的表面积常受限于背光模块的显示面板的尺寸而影响其散热效率，从而使背光模块因散热不佳导致其发光源过热，以导致缩短背光模块的使用寿命以及降低其发光效率。为提高散热效率，也有一些厂商在显示器的背板背面制作大量的散热鳍片来散发热量，通过增加散热鳍片的方式明显提升了散热效率，然而，这也直接导致了显示装置的厚度更大，整体也显得非常笨重，不符合现在电视机轻薄的发展潮流。
发明内容

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
参阅图1和图2，本发明实施例的显示装置主要包括导光板1、LED灯条10、散热板20、底座30以及水冷管40，LED灯条10，设于导光板1的入光端，LED灯条10发出的光线从侧面进入导光板1后，由导光板1匀光处理后自其顶面发出以作为背光源，底座30、散热板20、LED灯条10均设于导光板1的入光端所在侧。可以理解的是，显示装置内还具有显示面板、光学膜片等，本实施例中，显示装置内的显示面板、光学膜片等结构在此不做详细说明。
如图2，散热板20设于LED灯条10旁，LED灯条10贴合于散热板20的内侧并朝向导光板1的入光端，底座30与散热板20的外侧连接，用于支撑显示装置；水冷管40包括进口端、出口端和进口端、出口端之间的多段相连的弯折段，弯折段贴合在散热板20上，用于供冷却液流通，冷却液从进口端进入后从出口端流出，带走散热板20上的热量。
散热板20为L形铝挤，包括相互弯折的横板21和纵板22，LED灯条10贴合于横板21的内表面，纵板22与导光板1的背面相对设置。底座30采用导热性能较好的材质，如金属制成，其包括呈一夹角设置的底板31和支撑板32，支撑板32贴合于纵板22背离导光板1的面。纵板22与导光板1之间还可以具有 一层背板2，背板2作为导光板1的承载结构之一，为背板1提供一定的背部承托力，当显示装置使用时，散热板20位于底座30上，作为显示装置的承载件和背部边框。
这里，散热板20的横板21和纵板22互相垂直，底座30的底板31和支撑板32互相垂直，支撑板32位于底板31的中部。水冷管40为迂回曲折的弯管结构，整面贴合于横板21的外表面，以更好地传导横板21上的热量。
如图3，在水冷管40的进口端、出口端，分别利用导管60连接而顺着支撑板32延伸至底板31所在侧，具体地，导管60包括连接进口端的进液管61和连接出口端的出液管62，为冷却液提供动力的水泵50连接在进液管61的中部，进液管61、出液管62分别延伸至与底板31面接触，从而将自LED灯条10发出的热量传导至底板31，再散发到外界。
如图4和图5，作为其中一种实施方式，底板31内开设有散热通道310，散热通道310迂回设置，并同时与进液管61、出液管62连通。该散热通道310包括设于底板31内的多段互不相连的第二曲形槽310a以及底板31外分别连接每两个相邻的第二曲形槽310a的衔接管311。进液管61、出液管62分别自底板31的中部朝两端延伸后，与散热通道310连通。
每个第二曲形槽310a分别呈U形，第二曲形槽310a沿底板31的宽度方向延伸，所有的第二曲形槽310a沿底板31的长度方向依次排开，每个第二曲形槽310a的端部分别与临近的第二曲形槽310a的一端通过U形的衔接管311连通，从而形成一条完整的散热通道310，最终，散热通道310的两端分别位于底板31的长度方向的两端，再分别与进液管61、出液管62连通，从而形成水冷管40-水泵50-进液管61-散热通道310-出液管62-水冷管40的完整散热回路。水泵50工作过程中，将冷却液利用进液管61送入水冷管40，水冷管40内的冷却液在横板21背部往复曲折蜿蜒后，将自LED灯条10发出并传到至散热板20的热量带走，并自出液管62流经底板31内的曲折的散热通道310后将热量自底板31散发出，因此，冷却后的冷却液被重新由水泵50自进液管61送入水冷管40，如此往复循环，完成显示装置的散热过程。
如图6所示，作为另一种实施方式，本实施例的水冷管40的进口端、出口端可以均设于支撑板32所在侧，横板21内开设有弯曲设置的第一曲形槽，水冷管40的进口端、出口端分别插设于第一曲形槽的两端。进液管61、出液管62均穿设于支撑板32内，仅水泵50固定在支撑板32背面，自水泵50底部引 出的出液管62再次穿设于支撑板32内，支撑板32因此也可以作为散热的一种媒介。
综上所述，本发明通过提供一种新的显示装置的液冷散热构造，充分利用散热板和导热底座的散热能力，减小散热板的面积并避免使用散热鳍片，在保证显示装置轻薄化的前提下，使得显示装置具有良好的散热效果，显示装置的底座同时也作为散热构件的一部分，因此，也降低了液冷散热结构的成本，提升产品竞争力。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
