Technical Problem
[0003]公开号为CN213402381U的中国专利公开了一种防火密集型母线槽，包括母线槽本体，母线槽本体的一端安装有第一连接头，母线槽本体的另一端安装有第二连接头，母线槽本体的顶部和底部均通过连接筋板连接有第一防火钢板，母线槽本体的两侧均通过连接筋板连接有第二防火钢板，第一防火钢板和第二防火钢板的外侧活动连接有防火罩，整个母线槽的四周均连接有防火钢板，可以对母线槽进行防火保护，灵活性强，提高母线槽的使用寿命，但第一防火钢板、第二防火钢板等均采用不锈钢材料，其导热性能虽差(可延缓热量传导)，但也导致母线槽内部产生的热量难以通过钢板有效散发，当母线槽长时间高负荷运行时，内部铜排和绝缘板可能因散热不良而温度升高，加速绝缘材料老化，降低电气性能，甚至引发安全隐患
Benefits of technology
[0015]通过设置绝缘隔板和防火侧板等结构，内部散热依靠绝缘隔板上呈矩阵分布的圆形散热通孔，铜排运行产生的热量通过空气对流，经散热通孔在母线槽内部扩散，外部散热由顶部和底部的防火散热复合板与两侧防火侧板共同实现，防火散热复合板中，铝合金散热层搭配波浪形散热翅片，显著增大散热面积，加速热量向外界散发，防火侧板与母线槽本体形成通风通道，长条状通风孔沿长度方向等间距排列，利用热空气上升原理，驱动空气在通道内自然对流，快速带走母线槽表面热量，内外结合，高效降低母线槽运行温度。
