摘　　要：为了满足煤矿井下掘进设备的电气系统技术要求,针对目前矿用隔爆兼本质安全型变频调速电控箱存在的冷却问题,优化了现有的箱体冷却结构,通过仿真软件进行流场分析,并对冷却结构进行散热计算,为防爆电控箱壳体的冷却结构优化提供有力依据。In order to meet the technical requirements of the electrical system of the underground tunneling equipment in the coal mine,in view of the cooling problems existing in the current flameproof and intrinsically safe variable-frequency speed regulating electric cabinet for mining,optimized the existing cooling structure of the cabinet,analyzed the flow field through the simulation software,and calculated the heat dissipation of the cooling structure,which provides a strong basis for the optimization of the cooling structure of the explosion-proof electric cabinet shell.
