The liquid cooling unit comprises a refrigerant circulation system, a cooling liquid circulation system, an external pipeline and a deionization branch, and the deionization branch is arranged in a main circulation pipeline of the cooling liquid circulation system in parallel and used for purifying cooling liquid in the main circulation pipeline. A main circulating pipeline of the cooling liquid circulating system passes through a plate-type heat exchanger of the refrigerant circulating system and exchanges heat at the plate-type heat exchanger, the cooling liquid circulating system is communicated with an external pipeline to form an integral circulating system, and purified cooling liquid is introduced into the battery replacing bin and the battery pack through the external pipeline to carry out centralized heat management on the battery replacing bin and the battery pack. Different from a traditional independent battery liquid cooling system of a single battery, one liquid cooling unit is adopted, centralized heat management is conducted on a plurality of battery packs, and heat pipe and dehumidification can be conducted on a battery replacement bin; the device is also provided with a deionization branch, and a deionization tank in the deionization branch can remove corrosive ions from the cooling liquid.
本发明公开了一种换电站用带离子净化的液冷机组,包括制冷剂循环系统、冷却液循环系统、外部管道和去离子支路,所述去离子支路并联设置在冷却液循环系统的主循环管道中,对主循环管道中的冷却液进行净化,冷却液循环系统的主循环管道经过制冷剂循环系统的板式过换热器,并在此处进行热交换,冷却液循环系统与外部管道连通构成整体循环系统,经净化的冷却液通过外部管道通入换电仓和电池包对换电仓和电池包进行集中式热管理。本发明区别于传统的单个电池的独立电池液冷系统,采用一套液冷机组,对数个电池包进行集中式热管理,而且还可以对换电仓进行热管和除湿;本发明还设置了去离子支路,去离子支路中的去离子罐可将腐蚀性离子从冷却液中去除。
