The invention belongs to the technical field of battery packs, and provides a cooling system and a battery pack, the cooling system mainly comprises a plurality of cold plates and a bearing bottom plate; a first channel and a second channel which are independent from each other are arranged in each cold plate; the plurality of cold plates are arranged on the bearing bottom plate, and a mounting gap for mounting an electric core is formed between the two cold plates; a third channel and a fourth channel which are mutually independent are arranged in the bearing bottom plate, the first channel and the third channel are communicated in an inserted mode to form a first temperature control loop, and the second channel and the fourth channel are communicated in an inserted mode to form a second temperature control loop; the first temperature control loop is communicated with the cooling liquid supply loop, and the second temperature control loop is communicated with the air conditioner refrigerant supply loop. The heat exchange cooling requirements under different working conditions can be met, and the cooling effect and the application performance are improved.

    本申请属于电池包技术领域,提供一种冷却系统及电池包,主要包括若干冷板和承托底板;每一所述冷板内均设置有相互独立的第一通道和第二通道;若干所述冷板设置于所述承托底板,两所述冷板之间形成可供电芯安装的安装间隙;所述承托底板内设置有相互独立的第三通道和第四通道,所述第一通道与所述第三通道插接连通并形成第一温控回路,所述第二通道与所述第四通道插接连通并形成第二温控回路;所述第一温控回路与冷却液供应回路连通,所述第二温控回路与空调冷媒供应回路连通。本申请可以适配不同工况下的换热冷却需求,提高冷却效果以及应用性能。
