Description
技术领域
本实用新型涉及太阳能电池组件，具体涉及一种具备被动散热功能的新型太阳能电池板。
背景技术
太阳能电池板是太阳能发电系统中的重要部件，光照的能量部分转化为电能，剩余的大部分太阳能将会产生热量，这些热量如果积聚在太阳能电池板上将会大大降低其发电效率，热量过多时甚至会出现损坏电池的现象。因此为了保证太阳能发电系统的稳定工作，电池板的散热是亟待解决的关键问题。人们对太阳能电池板散热方法进行了大量的研究，一般采用风冷和水冷的形式对光伏电池进行冷却，但这些方式做成的散热装置不仅结构复杂，体积大，而且需要额外的能耗，进一步降低了太阳能发电的整体效率。因此，在光伏发电系统中，对电池板冷却技术的研究是个关键技术问题。据统计，太阳能电池组件温度每降低1度，输出电量将增加0.2%-0.5%，并且，长期在高温下工作的太阳能电池板会缩短其使用寿命，所以如何将太阳能电池板应用过程中的热量及时散出同时又不影响正常的发电是目前人们主要的研究方向。
实用新型内容
本实用新型的目的是解决以上问题，提供一种能有效降低太阳能电池板运行时温度，提高其光电转化效率并延长使用寿命的新型太阳能电池板。
本实用新型的目的是通过以下方式实现的：
一种带被动散热的新型太阳能电池板，包括太阳能电池板，所述太阳能电池板的采光面由数个排列的光伏组件构成，太阳能电池板的背光面另外设置有相变抑制材料以吸收光照产生的热量。
进一步地，所述相变抑制材料具有高传热密度（10-1000W/cm2）,高热导率（4000-6000W/(m·K)，可在-40oC 到 110oC之间工作。
进一步地，所述相变抑制材料封装在腔体中，腔体贴合在与太阳能电池板面积相当的板材上。
进一步地，上述板材可以是金属，玻璃与聚合物中的一种或几种。
进一步地，上述板材与太阳能电池板背面贴合，以达到最佳散热效果。
进一步地，上述板材的面积与单片太阳能电池板或组装后的太阳板阵列匹配。
本实用新型所产生的有益效果是：由于相变抑制材料具有极高的热导率与传热密度，可以将光照及光电转换过程产生的热量从电池组件内部迅速带走，使太阳能电池的温度与环境温度保持相同，可显著提高光电转换效率以及太阳能电池的使用寿命。同时，由于没有风扇及水冷等设施，大大简化了散热设计，而且不产生额外能耗。
附图说明
图1为根据本实用新型的利用相变抑制材料散热的新型太阳能电池板的结构示意图。
具体实施方式
下面结合附图和实施例进一步详细说明本实用新型，基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有实施例，都属于本实用新型所保护的范围。
本实施例，参照图1，一种带散热的新型太阳能电池板，包括太阳能电池板，所述太阳能电池板的采光面由数个整齐排列的电池组件构成，太阳能电池板的背光面另外设置有相变抑制散热板，散热板与太阳能电池板之间设置有绝缘/粘结层，使得两者有最大接触面积，利于导热，同时该粘结层起到结构固定与绝缘功能。相变抑制散热板的面积可以与单个电池板匹配（图1中的（b）部分）或相当于整个电池组件的面积（图1中的（c）部分）。前者的优势在于安装灵活，散热板之间互相绝缘。后者的优势在于设计简单，散热速度更快。在相变抑制散热板中，相变抑制材料通常封装在背对电池板的腔体中，以利于扩散热量到环境中，大大提高了光电转换效率。
