为了说明本申请所述的技术方案，以下结合具体附图及实施例进行详细说明。
如图1~3所示，本申请实施例提供的储能装置10，包括外壳100、多个储能罐200和电加热器400。外壳100具有供能端和放热端，图1及图3中外壳100的右侧为供能端、左侧为放热端，供能端用于与外界的供热设备连接，例如供能端与太阳能集热装置20连接；放热端用于与用户端（图未示）连接，例如通过循环管道与用户端的换热器耦合。多个储能罐200竖向间隔设置在外壳100中，储能罐200为中空的圆柱形，储能罐200可采用不锈钢材质，每个储能罐200的底部封闭，顶部通过旋盖封闭，储能罐200内封装有相变材料，相变材料为固-液相变材料，如采用水合盐复合相变材料，相较于采用水作为储能材料，其具有储能密度大、占用空间小的特点，且避免了外壳100内滋生细菌的问题。外壳100内设有篦子结构，该篦子结构用于固定外壳100内的所有储能罐200，相邻的两个储能罐200之间形成供传热介质流通的通道140。电加热器400设置在外壳100内且固定于多个储能罐200的底部，当外部的供热设备供能不足时，电加热器400启动，从而对储能罐200中的相变材料进行加热，或者，当白天供热设备储热能量不足时，夜间启动电加热器400，电加热器400利用谷电对储能罐200中的相变材料进行加热，如此，可节省使用成本，实现利用清洁能源的目的。
本实施例提供的储能装置10，外壳100内竖向设置有多个储能罐200，储能罐200封装有相变材料，可利用相变材料的固-液相转变过程实现热量的储存和释放，其储能密度大，能降低储能装置10的体积，减小设备占用空间，利于拓展其应用领域，适用性大，且储能装置10内不会滋生细菌，使用安全；外壳100内设篦子结构，可通过篦子结构固定各储能罐200，电加热器400能利用谷电对储能罐200中的相变材料进行加热，可节省使用成本，实现利用清洁能源的目的。
在一实施例中，如图1、图2所示，篦子结构包括上下间隔设置的两第一金属板300，两第一金属板300呈水平布设且均与外壳100的内壁连接固定，两第一金属板300的对应位置分别开设有多个第一通孔310和多个第二通孔320，各第一通孔310与各储能罐200的位置一一对应，各储能罐200穿设上下对应的各第一通孔310，多个第二通孔320用于供传热介质流通；第二通孔320可以但不仅限于是圆孔、椭圆孔、矩形孔或条形孔。在一实施方式中。两第一金属板300分别设于靠近储能罐200上下两端的位置，其中，靠近储能罐200底端的第一金属板300可起到支撑作用，靠近储能罐200顶端的第一金属板300可防止储能罐200倾斜。
在一实施例中，篦子结构还包括设于储能罐200底部的第二金属板330，即外壳100内共设有三块金属板。第二金属板330呈水平布设且周缘与外壳的内壁连接固定，第二金属板330与靠近底部的第一金属板300之间具有间隔，第二金属板330开设有多个第三通孔（图未示），第三通孔的直径小于储能罐的外径，多个第三通孔供传热介质流通。
在一实施例中，第二通孔320为圆孔，第二通孔320的直径设置为小于第一通孔310的直径。多个第一通孔310和多个第二通孔320可以是呈矩阵布设，也可以是呈其它形状布设；第二通孔320的数量可设置为多于第一通孔310的数量。
在一实施例中，相变材料为固-液相变储能材料，相变材料的相变温度为50~80℃，例如，相变材料采用有机相变材料或水合盐复合相变材料，具体可采用镁基水合盐复合相变材料，其储能密度大，且使用成本小。当相变材料被传热介质或者电加热器400加热时，由固态逐渐变为液态，当相变材料通过传热介质向用户端供热时，由液态逐渐变为固态。相变材料的相变温度为50℃~80℃，利用相变材料的固-液相转变过程实现热量的储存和释放，其相较于用水作为换热材料，采用熔盐相变材料，其储能密度大，能降低储能装置10的体积，进而减小设备整体的占用空间。
储能罐200内可设有多个金属导热板（图未示），该金属导热板与储能罐连接，多个金属导热板可交叉布设，例如，多个金属导热板竖向布设且呈十字交叉设置，也可以是平行间隔设置。
在一实施例中，外壳100包括顶部开口的箱体110和盖设于箱体110顶部开口处的盖体120，盖体120与箱体110可拆卸连接，例如通过连接于盖体120和箱体110四个边角处的螺栓121固定。盖体120顶部的四个边角处分别设有吊装结构122，箱体110的底部设有支撑结构500。需要对箱体110内的部件进行维护时，打开盖体120即可；需要移动运输储能装置10时，可通过吊装设备挂接盖体120顶部的各吊装结构122将储能装置10吊起，进而将储能装置10移动至预定位置，其安装、拆卸操作都非常方便。
箱体110的底部可焊接有多个角钢510，各角钢510可均匀布设，多个角钢510共同形成储能装置10的支撑结构500，角钢510取料容易，制作成本低，加工简单，另外，该支撑设计便于利用插车等工具将储能装置移动。
在一实施例中，储能罐200采用不锈钢材料，传热介质不会腐蚀储能罐200，可长期使用；外壳100的内壁设置有保温层130，该保温层130可采用高压发泡聚氨酯、保温棉等。
如图1、图3所示，本申请实施例提供的分体式太阳能集热系统，包括上述实施例的储能装置10、太阳能集热装置20、循环管路40、输送泵50和单向阀600。太阳能集热装置20包括至少一个太阳能集热器21，各太阳能集热器21内均设有传热介质，例如串联设置有多个太阳能集热器21。循环管路40设于太阳能集热装置20与储能装置10之间以及储能装置10与用户端之间，输送泵50设于循环管路40上，输送泵50用于驱动传热介质在储能装置10、太阳能集热器21及循环管路40内的循环流动，当太阳能集热器21内部的传热介质的温度高于储能装置10内部的传热介质的温度时，输送泵50启动，以避免太阳能集热器21内部温度过高，单向阀600设于循环管路40上，防止传热介质回流。分体式太阳能集热系统，其整体结构简单，部件组装方便，储能罐200中封装有相变材料，其储能密封大，设备整体占用的空间小，可广泛应用于农村、别墅、海岛、哨所等环境。
本实施例提供的分体式太阳能集热系统，太阳能集热装置20和储能装置10为分体设置，太阳能集热装置20可根据实际需求串联设置多个，储能装置10内的储能罐200封装有相变材料，其储能密度大，能降低储能装置10的体积，减小设备占用空间，拓展其应用领域，可广泛应用于农村、别墅、海岛、哨所等。
太阳能集热器21可采用真空管式太阳能集热器或平板式太阳能集热器；储能装置10两侧的循环管路40可采用相同材质或不同材质，例如均采用金属材质。用户端可设有热交换器，位于储能装置10放热端的循环管路40与热交换器耦合；位于太阳能集热器21与储能装置10之间的循环管路40的外表面包覆有隔热层（图未示），防止热量散失。
在一实施例中，传热介质的使用温度为-30℃~220℃，能避免冬季应用过程中循环管路40发生冻堵的风险，如此，系统适用的环境温度范围广，能适于较寒冷地区，在冬季使用也无冻堵风险，改变了传统采用热水为储热方式，通过储能装置10的放热可对客户端进行换热，热水可直接利用，避免了水被细菌等污染的风险。
在一实施例中，分体式太阳能集热系统还包括温度测量单元，该温度测量单元包括设置在各太阳能集热装置20的顶部的第一温度测量元件31和设置在储能装置10的外壳100的多个第二温度测量元件32。通过第一温度测量元件31可对太阳能集热装置20内部液体的温度进行实时监控，避免内部温度过高；多个第二温度测量元件32可均匀设置在外壳100的顶部，以测量得到更为准确的温度值。第一温度测量元件31和第二温度测量元件32均可采用热电偶，如采用铂电阻热电偶。
在一实施例中，如图1、图3所示，外壳100的第一侧壁开设有第一进液口101和第一出液口102，太阳能集热装置20的两端分别连接有一段用于流通传热介质的循环管路40，输送泵50设于太阳能集热装置20与第一出液口102之间的循环管路40上，单向阀600设于太阳能集热装置20与第一进液口101之间的循环管路40上；外壳100的第二侧壁开设有第二进液口103和第二出液口104，第二进液口103和第二出液口104分别与循环管路连接，即通过一侧的循环管路与用户端的换热器耦合，以完成能量的传递。也就是说，外壳100的第一侧壁形成供能端，第二侧壁形成放热端。在一实施方式中，第一侧壁和第二侧壁为外壳100相对的两侧壁，第一出液口102和第一进液口101分设于靠近第一侧壁上下两端的位置，第二出液口104和第二进液口103分设于靠近第二侧壁上下两端的位置，第一进液口101和第二进液口103均位于篦子结构中靠近底部的第二金属板330与外壳100之间，第一出液口102和第二出液口104均位于篦子结构中靠近顶部的第一金属板300与外壳100之间。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
