The invention relates to the technical field of new energy vehicles, in particular to a battery heat dissipation device special for a new energy vehicle. The battery heat dissipation device special for the new energy vehicle comprises a battery pack heat exchange mechanism, a radiator and a heat exchange liquid circulation assembly, wherein the battery pack heat exchange mechanism comprises a main heat exchange shell formed by assembling an upper shell and a lower shell, a first cavity used for heat exchange of a battery pack is formed in an inner cavity of the upper shell, and a second cavity used for letting in cooling liquid is formed in an inner cavity of the lower shell. A partition plate used for partitioning the upper shell and the lower shell and a supporting piece used for bearing the battery pack are sequentially arranged in an inner cavity of the main heat exchange shell from bottom to top. The device has the beneficial effects that an immersion type heat exchange mode is adopted, the heat exchange efficiency is better, heat generated during operation of the battery pack can be rapidly guided out so as to avoid long-time accumulation of the heat in the battery, the risk of causing a fire disaster is reduced, and the whole battery is safer in the practical process.

    本发明涉及新能源汽车技术领域,具体为一种新能源汽车专用电池散热装置。本发明涉及一种新能源汽车专用电池散热装置,包括电池组换热机构、散热器以及和换热液循环组件;所述电池组换热机构包括由上壳体以及下壳体装配而成的主换热壳体,上壳体内腔形成一个用于电池包换热的第一空腔,下壳体内腔形成一个用于导入冷却液的第二空腔;所述主换热壳体内腔由下至上依次设置用于分隔上壳体以及下壳体的分隔板和用于承载电池包的支撑件。本发明的有益效果是:采用沉浸式换热方式,换热效率更佳,能迅速将电池组件运转时产生的热量导出,以避免热量长时间在电池内部堆积,降低了引发火灾的风险,使得整个电池实用过程中更加安全。
