The invention discloses an electric automobile outdoor combined charging system, and relates to the technical field of outdoor charging systems, the electric automobile outdoor combined charging system comprises outdoor charging piles which are symmetrically distributed in a front-back mode, and the bottom ends of the outdoor charging piles which are distributed in the front-back mode are installed on the surface of the same base. Heat dissipation channels are formed in the opposite surfaces of the outdoor charging piles distributed front and back, inner cavities of the heat dissipation channels are communicated with one another, alignment covers are fixedly connected to the edges of the heat dissipation channels, slidable butt joint frames are arranged on the inner sides of the alignment covers, and a plurality of heat dissipation through holes are formed in the surfaces of the butt joint frames. The outdoor charging pile is suitable for meeting the requirement for efficient heat dissipation of the outdoor charging pile in normal-temperature weather, and damage to an electric power assembly in the outdoor charging pile in a high-temperature environment is avoided. And meanwhile, the heat preservation requirement of the outdoor charging pile in low-temperature weather is met, the adverse effect of the low-temperature environment on operation of the power assembly is reduced, and the purpose of fully protecting the outdoor charging pile is achieved.

本发明公开了一种电动汽车户外组合充电系统，涉及户外充电系统技术领域，包括有前、后对称分布的户外充电桩，前、后分布的所述户外充电桩的底端安装于同一底座的表面，前、后分布的所述户外充电桩的相对表面均开设有其自身内腔相贯通的散热通道，所述散热通道的边缘处均固定连接有对位罩，所述对位罩的内侧设置有可滑动的对接框，所述对接框的表面开设有多个散热通孔。本发明设适用于在常温天气中，户外充电桩的高效散热需求，高温环境下对户外充电桩内部电力组件所产生的损伤。同时适用于低温天气下户外充电桩的保温需求，减少低温环境对电力组件运转所产生的不良影响，以达到充分保护户外充电桩的目的。
