Description

一种新型光伏二极管
技术领域
本实用新型涉及一种新型光伏二极管,特别涉及对光伏二极管内部结构的改进。
背景技术
随着光伏产业的快速发展,太阳能组件对光伏二极管散热能力和使用寿命的要求也越来越高。目前市场上光伏二极管受其结构的影响,散热能力较差,导致现有光伏二极管温度升高较快,可能会使太阳能组件的接线盒变形,导致整个组件使用寿命短;因此,要满足现在太阳能组件对光伏二极管散热能力较强和使用寿命长等要求,就必须要求光伏二极管具有新型性高散热能力且使用寿命长的特点。
实用新型内容
本实用新型所要解决的技术问题是提供一种现在太阳能组件所需求的高特效、易散热、使用寿命长的新型光伏二极管。    
本实用新型解决上述技术问题的技术方案如下:一种新型光伏二极管,包括两根铜引线,肖特基二极管芯片,圆柱体封装外壳,所述第一根铜引线,肖特基二极管芯片,第二根铜引线依次连接,所述圆柱体封装外壳将所述肖特基二极管芯片包覆其中,所述每根铜引线均有一端伸出圆柱体封装外壳外部,在所述圆柱体封装外壳内填充高导热封装树脂。
在上述技术方案的基础上,本实用新型还可以做如下改进。
进一步,所述位于圆柱体封装外壳内部的、每根铜引线与台面相接触的一端的宽度大于铜引线其它部分的宽度。
采用上述进一步方案的有益效果是采用压扁的铜引线和高导热封装树脂,是本实用新型具有散热能力强、使用寿命长的特点 。
附图说明
图1为本实用新型内部结构示意图;
附图中,各标号所代表的部件列表如下:
1、第一根铜引线,2、肖特基二极管芯片,3、圆柱体封装外壳, 4、第二根铜引线,5、高导热封装树脂。 
具体实施方式
以下结合附图对本实用新型的原理和特征进行描述,所举实例只用于解释本实用新型,并非用于限定本实用新型的范围。
如图1所示,包括两根铜引线,肖特基二极管芯片 2,圆柱体封装外壳 3,所述第一根铜引线 1,肖特基二极管芯片 2,第二根铜引线 4依次连接,所述圆柱体封装外壳 3将所述肖特基二极管芯片 2包覆其中,所述每根铜引线均有一端伸出圆柱体封装外壳 3外部,在所述圆柱体封装外壳 3内填充高导热封装树脂 5。
所述位于圆柱体封装外壳 3内部的、每根铜引线与二极管芯片相接触的一端的宽度大于铜引线其它部分的宽度。
目前由于材料受内部结构的影响,在引线不能打造成双钉头引线时,将引线接近台面根部进行打扁,此处打扁,大大减小外力对晶粒的损伤,同时也起到易散热、延长使用寿命等优点。
以上所述仅为本实用新型的较佳实施例,并不用以限制本实用新型,凡在本实用新型的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本实用新型的保护范围之内。
