The invention discloses a lithium ion battery pack heat dissipation device, which relates to the field of power batteries, and is provided with a divergent pipe, a first heat conduction column, a second heat conduction column and a phase change material. The divergent pipe, the first heat conduction column, the second heat conduction column and the phase change material are combined, so that the temperature difference among the positive electrode region, the middle region and the negative electrode region of the single battery in the battery pack is better reduced, the service life of the single battery is prolonged, and the heat dissipation rate of the battery pack is increased.

    本发明公开了一种锂离子电池包散热装置,涉及动力电池领域,本发明设置有渐扩管、第一导热柱、第二导热柱、相变材料。本发明采用渐扩管、第一导热柱、第二导热柱和相变材料的结合,更好的降低了电池包中电池单体正极区域、中间区域和负极区域之间的温差,延长电池单体的使用寿命,提高了电池包的散热速率。
