【背景技术】
随着液晶技术的发展，对于液晶显示装置散热的要求也越来越高。现有技术中背光模组主要采用LED背光，通过铝挤等散热部件对LED进行散热。而为了达到更好的散热效果，液晶显示装置通常需要采用大幅宽的铝挤。
在现有的铝挤挤出工艺中，当需要增加铝挤的幅宽时，铝挤的厚度也需要相应增加，否则会由于铝挤厚度太薄造成铝挤平整度不好，从而无法顺利挤出铝挤型材。铝挤厚度增加会增加铝挤的用料成本，且不利于液晶显示装置的轻薄化设计。
【发明内容】
本发明实施例主要解决的技术问题是提供一种用于液晶显示装置的背光模组及其散热部件的制造方法，能够降低生产成本并实现产品的轻薄化。

其中，空心管的材料为铝材。
其中，制备空心管的步骤还包括：通过模具挤出或拉拔成型制造空心管。
其中，制备空心管的步骤还包括：在第一承载部靠近第一竖直部的一端和第二承载部靠近第二竖直部的一端分别设置第一凸筋和第二凸筋，第一凸筋和第二凸筋的内表面突出于第一承载部和第二承载部的内表面。
其中，切割空心管的步骤包括：将第一凸筋和第二凸筋的内表面设置为平面，沿第一凸筋的内表面和第二凸筋的内表面将空心管切成两块散热部件。
为解决上述技术问题，本发明采用的又一个技术方案是：提供一种用于液晶显示装置的背光模组，包括光学部材和光源，该背光模组还包括散热部件。散热部件包括承载部和竖直部，承载部和竖直部相连接且垂直设置。其中，承载部用于承载光学部材，竖直部用于设置光源。

本实施例散热部件的制备方法包括以下步骤。
步骤S101: 制备空心管20。
优选地，本实施例用铝制作空心管20（亦即铝挤）。当然，空心管20也可以由其他的散热材料制作而成，在此不作限定。
本发明实施例中可以通过模具挤出或拉拔成型等方式制备空心管20，也可以通过其他的方式制备空心管20，其制备方式在此不作限定。
如图2a和图2b所示，具体而言，本实施例制备出来的空心管20为中空结构，包括相连接的第一承载部211、第二承载部212、第一竖直部221以及第二竖直部222，使空心管20沿其横向方向的截面呈“回”型。优选地，第一承载部211垂直于第一竖直部221以及第二竖直部222设置，第二承载部212垂直于第一竖直部221以及第二竖直部222设置，也可以根据需要使第一承载部211、第二承载部212与第一竖直部221以及第二竖直部222成一定角度倾斜设置，在此不作限定。
进一步而言，本实施例在制备空心管20的同时，在第一承载部211靠近第一竖直部221的一端设置第一凸筋2111，在第二承载部212靠近第二竖直部222的一端设置第二凸筋2121。第一凸筋2111和第二凸筋2121分别凸出于第一承载部211和第二承载部212的内表面设置，其设计的目的在于增强空心管20的强度，防止铝挤波浪形形变。优选地，第一凸筋2111和第二凸筋2121的内表面为平面，方便于空心管20的制造也有利于空心管20的切割。当然，根据设计的需要，第一凸筋2111和第二凸筋2121的内表面也可以设计成不同的曲面或者各种不规则的形状，在此不作限定。
本实施例在制备空心管20的同时，在第一承载部211与第一竖直部221和第二竖直部222连接处、第二承载部212与第一竖直部221和第二竖直部222连接处均设置过渡角23。优选地，过渡角23为倒C角，当然，也可以设置为平滑过渡的倒圆角，在此不作限定。过渡角23的目的在于增加热流通道，提升液晶显示装置的热量传输速度。
步骤S102：切割空心管。
如图3a和图3b所示，本实施例沿第一凸筋2111的内表面和第二凸筋2121的内表面将空心管20切成两块散热部件。其中，第一承载部211和第一竖直部221形成一个散热部件，第二承载部212和第二竖直部222形成另一个散热部件。
本发明实施例首先制备沿横向方向截面呈“回”型的空心管20及其相连接的第一承载部211、第二承载部212、第一竖直部221和第二竖直部222；再沿纵向方向分别切割空心管20的第一竖直部221和第二竖直部222，将空心管20切成两个散热部件。本发明实施例通过设计一种“回”型的空心管20，能够增强散热部件的强度，而且还克服了现有技术中由于散热材料强度不足从而无法挤出轻薄型散热部件的问题。本发明实施例能够降低散热材料的生产成本，实现了液晶显示装置的轻薄化设计。
请参阅图4，图4是本发明一实施例散热部件的结构示意图。本发明实施例还提供一种用于液晶显示装置的散热部件。该散热部件40由本发明第一实施例提供的方法制备而成，其具体制备方法已经在上文中作了详细说明，故在此不作赘述。
如前所述，散热部件40包括承载部41、竖直部42以及凸筋411，此外，承载部41与竖直部42之间设置有过渡角43。散热部件40整体可以呈“L”型，由于散热部件40各部分结构以及功能已经在上文作了详细说明，故在此不作赘述。
不难理解，由于本实施例40由本发明第一实施例的制备方法制备所得，本实施例散热部件40相比较于现有的散热部件而言更为轻薄化，有助于降低液晶显示装置的成本。
本发明实施例还提供一种背光模组。具体请参阅图5，图5是采用图4所示散热部件的背光模组的部分结构示意图。
在本实施例中，背光模组包括光学部材（图未示）、光源54以及前面实施例所述的散热部件。该散热部件包括承载部51、竖直部52以及凸筋511，此外，承载部51与竖直部52之间设置有过渡角53。散热部件各部分结构以及功能已经在上文作了详细说明，在此不作赘述。光源54可以通过导热胶贴附或通过螺丝锁附于竖直部52之上，其固定方式在此不作限定。
容易理解的是，本实施例背光模组采用了前面实施例所述的散热部件，能够实现背光模组的散热部件的轻薄化设置，降低散热部件的用料成本从而降低液晶显示装置的成本。
本发明实施例还提供一种液晶显示装置，该液晶显示装置包括液晶面板以及本发明第三实施例的背光模组。液晶面板设置于背光模组之上。而由于背光模组的结构已经在上文作了详细说明，故在此不再赘述。
不难理解，本实施例采用了前面实施例所述的背光模组，能够实现液晶显示装置的散热部件的轻薄化设置，降低散热部件的用料成本从而降低液晶显示装置的成本。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
