Abstract
一种翅片排孔金属光伏背板，由排孔金属板1、翅片2组成，其特征为：排孔金属板1为两块以上大板中间被连板3连接隔离成多个排孔通道4，翅片2在排孔通道4内与表面板5相连，光伏电池6与表面板5粘贴。这样，光伏电池6工作时就会把产生的热量迅速地传递给与其紧贴的翅片排孔金属光伏背板的表面板5，表面板5再把热量传递给翅片2和连板3，翅片2和连板3再把热量传递给翅片和连板周边的空气，排孔通道4内部空气因受热而密度变低，气流因浮力向上流动产生烟囱效应，从而光伏电池产生的热量从这一排排的小烟囱中被带向空中，降低电池温度。
Description
技术领域
本发明涉及到一种太阳能光伏发电设备。
背景技术
一般光伏电池的光电转换效率为10％～ 20％，在运行的过程中，未被利用的太阳辐射能除了一部分被反射外 其余大部分被电池吸收转化为热能；如果这些吸收的热量不能及时排除，电池温度就会逐渐升高，发电效率降低(据统计电池组件温度每上升1摄氏度，其发电功率衰减0.4％)，而且光伏电池长期在高温下工作会迅速老化、缩短使用寿命。现在电池降温技术主要是背板材质和结构的改进，现有的背板材料一般由几种高分子材料复合而成，如采用TPT、TPE、FPE等结构，但由于高分子材料的导热系数一般都较低无法有效散热，使得组件运行产生的热量不能有效的导出，导致热量积蓄。光伏电池散热的方法有被动散热与主动散热两种。前者依靠大气的自然流动带走电池热量，后者依靠电力驱动风机或泵，强制空气、水或其他流体流过人为设置在太阳电池组件上的散热设备，强化电池热量的散出过程，或者仅在太阳电池组件上增加散热设备，强化自然对流散热。由于聚光式太阳电池组件工作在数个至数十个太阳之下，不加强散热时电池温度可达上千度，组件会遭到破坏，故聚光式太阳电池组件均采取强化散热措施，例如中国专利CN101145743太阳电池高效发电散热系统，在太阳电池组件下部附加导热片和散热构件，强化向大气散热，中国专利CN201000896水冷式光伏发电系统，以导热硅胶粘接导热水管于太阳电池组件下方，管内有水循环流动对聚光式太阳电池进行冷却。此外在太阳能光伏热综合利用中，例如中国专利CN1716642，混合式光电光热收集器，中国专利CN1563844太阳电热联产装置，中国专利CN1988183太阳电池的电热联用装置，都利用水循环流过太阳电池组件背部来提取热能，同时也起到降低太阳电池温度的作用。对于普通的平板式太阳电池组件，一般认为设置复杂的散热系统意义不大，基本上未特别考虑散热问题， 其工作温度常达到50℃以上。目前散热效果最好的是一种微热管（导热性是铝的5000倍，石墨烯的200倍）平板贴附背板的散热技术------CN200810239002.0光伏电池散热装置：微热管散热平板的一侧与光伏电池板背面相贴合，且散热平板为中空结构，其内部同向设置有大量的微孔管群或微槽群，并灌装有甲醇等工质，各微孔或微槽自然形成微热管结构，所述散热平板与光伏电池板相贴合的一侧为吸热面，散热平板的其余侧面的部分或全部为散热面。散热效果非常好，但是价格是光伏板的1—2倍。对这些组件采用简便而又有效的散热措施来降低其工作温度是方向，如采用全金属背板（ZL200820200742. 9,CN201120084141. 8)，但单纯依赖表面的氧化层并不能很好的满足背板材料对于长时间绝缘性的要求，使得实际过程中组件面临安全性问题，同时所采用的金属层过厚不利于组件运输和降低成本。
发明内容
本发明从太阳电池组件结构热设计入手，提供一种廉价的翅片排孔金属光伏背板，来解决减少太阳电池散热热阻，用自然冷却方式-------太阳能烟囱，降低太阳电池工作温度的问题。本发明技术方案如下：本翅片排孔金属光伏背板由排孔金属板1、翅片2组成，其特征为：排孔金属板1为两块以上大板中间被连板3连接隔离成多个排孔通道4，翅片2在排孔通道4内与表面板5相连，光伏电池6与表面板5粘贴。这样，光伏电池6工作时就会把产生的热量迅速地传递给与其紧贴的翅片排孔金属光伏背板的表面板5，表面板5再把热量传递给翅片2和连板3，翅片2和连板3再把热量传递给翅片和连板周边的空气，排孔通道4内部空气因受热而密度变低，气流因浮力向上流动产生烟囱效应，从而光伏电池产生的热量从这一排排的小烟囱中被带向空中，降低电池温度。这里的连板3实质上也是散热翅片。为了提高散热效果，翅片和连板上可以增加分支翅片。
附图说明
下面结合附图和实施例对本发明进一步说明：
图1是本发明的结构示意图。
图2是本发明的结构示意图。
图3是本发明的结构示意图。
图4是本发明的结构示意图。
图中1. 排孔金属板，2.翅片，3. 连板，4. 排孔通道，5. 表面板，6.光伏电池，7.阳极氧化层，8. EVA胶膜，9. 翅片排孔金属背板光伏板，10. 方管肋筋。
具体实施方式
在图1中，展示了翅片排孔金属光伏背板的结构：排孔金属板1为两块以上大板中间被连板3连接隔离成多个排孔通道4，翅片2在排孔通道4内与表面板5相连,这里的表面板不只一面。
在图2中，翅片排孔金属光伏背板为整体挤出的铝合金材质，再整体做了阳极氧化，形成了第一道绝缘层----10～30μm厚的阳极氧化层7（图中只显示了上表层，下表层省略了），然后按排孔金属板1、阳极氧化层7、EVA胶膜8、光伏电池（膜）6（硬质电池片按：排孔金属板、阳极氧化层、EVA胶膜、覆盖电池背面的连接条和电极引线聚酯薄膜条、光伏电池片、EVA胶膜、透光面板）的顺序以“三明治”方式叠合,真空加热层压成一个整体----翅片排孔金属背板光伏板9）。
在图3中，翅片排孔金属光伏背板为增加了方管肋筋10整体挤出的铝合金型材，这里方管肋筋10替代了常规太阳能背板的粘贴方管边框，工艺上简化了很多。
在图4中，翅片排孔金属背板光伏板9铺设在车厢的顶面和侧面，车辆行驶过程中所形成的气流自然穿过翅片排孔金属背板的排孔通道，带走翅片散发的热量。车辆停驶时可停在一个斜坡（或抬高车头车尾其中一头），这样车厢顶面和侧面的翅片排孔金属背板光伏板9就进入太阳能烟囱散热状态。
