The invention discloses a central liquid cooling fast charging station system. The system comprises at least one charging pile unit which is provided with a cooling liquid inlet end and a cooling liquid outlet end, a cooling liquid circulation subsystem and a cooling water circulation subsystem. The cooling liquid circulation subsystem is used for providing closed circulation of cooling liquid andcomprises a heat exchanger and a liquid feeding pump which are connected in sequence, the cooling liquid outlet ends of all the charging pile units are connected in parallel and then connected with an inlet of the heat exchanger in a butt joint manner, the cooling liquid inlet ends of all the charging pile units are connected in parallel and then connected with an outlet of the liquid feeding pump in a butt joint manner, cooling liquid is provided for each charging pile unit through the liquid feeding pump for heat dissipation and cooling, and then high-temperature cooling liquid flows back to the heat exchanger; and the cooling water circulation subsystem is used for cooling the high-temperature cooling liquid in the heat exchanger. According to the invention, one set of central liquid cooling fast charging station system is used, the liquid cooling requirements of more charging piles are met, the internal structures of the liquid cooling charging piles are simplified, the cost is reduced, the charging efficiency of the charging piles is greatly improved, and the operation stability and reliability of the charging piles are ensured.

    本发明公开了一种中央液冷快充电站系统,包括:至少一个充电桩单元,充电桩单元上设置有冷却液入口端和冷却液出口端;用于提供冷却液封闭循环的冷却液循环子系统,其包括:依次连接的热交换器及送液泵,所有充电桩单元的冷却液出口端并联后对接热交换器的入口,所有充电桩单元的冷却液入口端并联后对接送液泵的出口,通过送液泵为每个充电桩单元分别提供冷却液散热降温,之后高温冷却液再回流至热交换器;以及为热交换器内高温冷却液降温的冷却水循环子系统。本发明用一套中央液冷快充电站系统,满足更多充电桩液冷需求,简化液冷充电桩的内部结构,降低成本,大幅提升充电桩的充电效率,确保充电桩运行的稳定性和可靠性。
