The invention discloses a battery module and engineering machinery, relates to the field of batteries, and aims to improve the thermal management effect of the battery module and improve the refrigeration effect and temperature uniformity of the battery module. The battery module comprises a battery cell, a first refrigeration assembly and a second refrigeration assembly, the first refrigeration assembly is attached to the first side face of the battery cell. The second refrigeration assembly is attached to the second side face of the battery cell, and the first side face is parallel to the second side face. Flow paths of the first refrigeration assembly and the second refrigeration assembly are independent. In the first direction, the first inlet of the first refrigeration assembly is located on one side of the first outlet of the first refrigeration assembly, and the second inlet of the second refrigeration assembly is located on the other side of the second outlet of the second refrigeration assembly. According to the technical scheme, the cooling efficiency and the cooling effect on the battery cell can be improved, the temperature uniformity of the battery cell is improved, and the service life of the battery cell is prolonged.

    本发明公开了一种电池模组以及工程机械,涉及电池领域,用以提高对电池模组的热管理效果,提高电池模组的制冷效果及温度均匀性。电池模组,包括电芯、第一制冷组件和第二制冷组件。第一制冷组件与电芯的第一侧面贴合布置。第二制冷组件与电芯的第二侧面贴合布置,第一侧面和第二侧面平行。其中,第一制冷组件和第二制冷组件的流路是独立的;其中,沿着第一方向,第一制冷组件的第一入口位于第一制冷组件的第一出口的一侧,第二制冷组件的第二入口位于第二制冷组件的第二出口的另一侧。上述技术方案,可以改善对电芯的冷却效率和冷却效果,提升电芯自身的温度均匀性,提高电芯的使用寿命。
