The invention relates to a lithium battery liquid cooling phase change heat dissipation structure, which comprises a battery block, a phase change heat transfer plate and a liquid cooling plate, the liquid cooling plate is arranged on the lower side of the battery block, the upper end of the phase change heat transfer plate is an evaporation end, the evaporation end is attached to the evaporation surface of the battery block, the lower end of the phase change heat transfer plate is a condensation end, and the condensation end is attached to the condensation surface of the liquid cooling plate. And the evaporation surface and the condensation surface are positioned on the same plane. The lithium battery can still meet the heat dissipation requirement of the lithium battery under the condition of rapid charging, can rapidly conduct heat and reduce temperature, prevents thermal runaway accidents, and has a wide development prospect in the field of heat dissipation of the lithium battery.

    本发明涉及一种锂电池液冷相变散热结构,包括电池块、相变传热板和液冷板,液冷板设置于电池块的下侧,相变传热板的上端为蒸发端,蒸发端相贴于电池块的蒸发面,相变传热板的下端为冷凝端,冷凝端相贴于液冷板的冷凝面,蒸发面和所述冷凝面位于同一平面。该发明能够在快充下条件下仍能满足锂电池的散热要求,能够快速导热降温,防止发生热失控事故,在锂电池的散热领域具有广阔的发展前景。
