The explosion-proof charger comprises an explosion-proof shell, an electrical system and a heat dissipation unit, the explosion-proof shell comprises an explosion-proof outer shell, an explosion-proof side door and a plurality of partition plates, and the partition plates are fixedly arranged in the explosion-proof outer shell to divide the interior of the explosion-proof outer shell into a main cavity and a power module cavity; the explosion-proof side door is movably connected with the explosion-proof shell so as to close or open the power module cavity; the electrical system comprises a power module detachably arranged in the power module cavity, and the heat dissipation unit is used for dissipating heat of the power module. Compared with the prior art, the explosion-proof charger provided by the invention has the advantages that the power module is independently arranged in the power module cavity, only the power module cavity needs to be opened during replacement, and other electrical components are still isolated in the main cavity, so that corrosion of a severe external environment to the other electrical components can be avoided, and the service life of the power module is prolonged. And when explosion occurs, energy propagation can be blocked, and electrical components in the main chamber can be protected.

    本发明涉及一种隔爆型充电机,包括防爆壳体、电气系统、散热单元,防爆壳体包括防爆外壳、防爆侧门以及若干隔板,隔板固定设置于防爆外壳内以将防爆外壳内部分隔出主腔室和功率模块腔室,防爆侧门与防爆外壳活动连接用以封闭或开启功率模块腔室;电气系统包括可拆卸设置于功率模块腔室内的功率模块,散热单元用以对功率模块散热。与现有技术相比,本发明提供的隔爆型充电机将功率模块单独设置于功率模块腔室内,在更换时只需要打开功率模块腔室,而其余的电气部件依然被隔绝于主腔室内,既能避免恶劣的外界环境对其他电气部件的腐蚀,又能在发生爆炸时阻隔能量传播,保护主腔室内的电器元件。
