具体实施方式
下面结合附图并通过可选实施方式来说明本公开的技术方案。
结合图1至图4所示，本实施例中一种太阳能集热器，该太阳能集热器可以为盘管蜂窝腔式液体工质太阳能集热器，包括设置有太阳光入射口的保温装置、设置于保温装置的箱体内的吸热装置2、以及与吸热装置2相连接用于传热介质从吸热装置2的中部流向四周的导流装置3；可选的，吸热装置2为均布于保温装置箱体内的4*4个呈空心圆柱形设置的集热盘管21；导流装置3包括主流管，以及对称设置于主流管两侧的支流管，支流管分别与集热盘管21的输入端和输出端相连接。
可选的，结合图3所示，本实施例中的集热盘管21由2根集热管211并行螺旋缠绕而成，2根集热管211的端部可以是分别设置有用于和支流管相连接的4个第一接头法兰212，4个第一接头法兰212分别位于集热盘管21的同一端，且相邻集热管211之间设置有用于补偿集热管211热变形余量的间隙。以此方式设计的集热盘管21，两根集热管211经并行螺旋缠绕后四个端口均折弯于集热盘管21的同一端，之后，如图7所示，将4*4个集热盘管21通过支撑架6纵横均布到真空壳体11内，且使得集热盘管21折弯有四个端口的一端均朝向真空壳体11内底面方向设置，并使得每个端口通过第一 接头法兰212与导流装置上的支流管贯通连接。以此方式设置，能够通过地面太阳能镜群的集中照射，使得集热盘管中的加热熔盐有效吸热，并通过导流装置的作用，将热量通过加热熔盐导出，之后再将冷却后的加热熔盐重新倒入集热盘管，依此循环并源源不断的对蒸汽锅炉进行加热。
本实施例中，结合图2所示，导流装置3还包括与主流管垂直贯通设置的进流管33和出流管34，进流管33和出流管34贯穿保温装置与外部热交换装置相连接。主流管包括横向设置于进流管33下端的第一主流管311、设置于第一主流管311下方且与第一主流管311平行设置的第二主流管312、纵向设置于第二主流管312两端上方的第三主流管313、横向设置于第三主流管313两端上方的第四主流管314、以及纵向设置于相邻第四主流管314之间的第五主流管315，第五主流管315为弯折结构，可以是呈几字形(也可以称为Ω字型)设置，即参见图2，定义所述第五主流管315中间部分延伸方向为第一方向，所述第五主流管315的两端沿垂直于所述第一方向的第二方向延伸第一预设长度，然后再沿所述第一方向延伸第二长度；且第五主流管315的中部垂直设置有出流管34。沿第二主流管312和第三主流管313的长度方向分别均布有倒U字型的支流管32，支流管32的端部设置有用于和第一接头法兰212相配合的第二接头法兰321。以此结构设计，能够方便高效的使得加热熔盐依次沿多个集热盘管流进流出，进而循环流动，快速高效的进行热量的收集和传递。
本实施例中，在地面太阳能镜群透过真空壳体11上的太阳光入射口对多个集热盘管21进行照射时，由于位于中部的集热盘管采光面积较大，而位于中部集热盘管四周的集热盘管采光面积相对较小，因此为了防止流入中部集热盘管中的加热熔盐的温度过高，对集热盘管造成损伤，本实施例中加热熔 盐的流动通过导流装置的使用，采用“先中部后四周”的方式进行流动，以此均衡各处集热盘管中的加热熔盐的温度，故采用上述方案对导流装置进行设计，以此使得温度较低的加热熔盐通过进流管、第一主流管311及支流管同时流入中部四个集热盘管中，之后再通过支流管及第二主流管312流出后流入与中部四个集热盘管左右两边的四个集热盘管中，之后再通过支流管和第三主流管流出后流入4*4个集热盘管的四角，然后再通过支流管和第四主流管流出后流入中部四个集热盘管上下两边的四个集热盘管中，最后通过第五主流管315中部的出流管34流出，依此完成加热熔盐的依次循环流动。
为了防止位于真空壳体11中部的吸热装置吸收到的热量流失，防止加热熔盐因温差造成固化，可选的，本实施例中在保温装置的太阳光入射口处还设置有密封盖，避免无光照时，熔盐快速冷却。
此外如图4至图6所示，本实施例中的保温装置包括真空壳体11、包覆于真空壳体11外围且与真空壳体11间隙设置的外壳体13、以及填充于外壳体13与真空壳体11之间的保温层12，真空壳体11由多片真空板111组成，真空板111包括第一防辐射板1111和第二防辐射板1112，以及夹设于第一防辐射板1111和第二防辐射板1112之间真空腔体内的第一网状支架1113，保温层12与外壳体13之间设置有第二网状支架14。以此结构设计，除了能够使得该保温装置具有一定的结构强度，同时，还能够通过真空壳体及保温层的设置，与外界温度形成有效隔离，进而对真空壳体中的吸热装置起到很好的保温效果，避免热量的流失。
为了防止加热熔盐溢漏等异常情况的发生，对保温装置造成污染，本实施例中，在保温装置的箱体内设置有防漏收纳盒8，防漏收纳盒8位于吸热装置2和导流装置3的下方。以此能够对溢漏对加热熔盐进行有效收集，防 止四处外溢。
工业实用性
本实施例提供一种太阳能集热器，通过导流装置的设置，使得传热介质从吸热装置的中部向四周流动，进而使得每个集热盘管中的传热介质温度均等的流入流出，从而使得吸热装置高效的进行热量传递，同时，通过保温装置的作用，有效防止热量流失。
