The invention belongs to the field of engines, and discloses a lithium battery pack for starting and stopping an engine, a lithium battery core is continuously and rapidly cooled by introducing cooling fluid from the outside, so that the cooling efficiency of the lithium battery pack for starting and stopping the engine is remarkably improved, the environment temperature of the lithium battery pack is rapidly reduced, and the service life of the lithium battery pack is prolonged. Comprising a battery shell, a plurality of lithium cells and a hollow radiator, the hollow radiator is arranged between the lithium cells and the inner wall of the battery shell, the hollow radiator is provided with a conformal surface, a fluid overflowing cavity, a fluid inlet and a fluid outlet, the conformal surface is matched with the circumferential surfaces of the lithium cells, and external cooling fluid flows into the fluid overflowing cavity through the fluid inlet and flows into the fluid overflowing cavity through the fluid outlet. And when the cooling fluid flows through the conformal surface, the lithium battery core conducts heat through the conformal surface and continuously takes away the heat through the cooling fluid.

    本发明属于发动机领域,公开了一种用于启停发动机的锂电池包,通过自外部引入冷却流体对锂电芯进行持续地快速冷却,从而使得启停发动机的锂电池包的降温效率显著提升,迅速降低锂电池包的环境温度,包括电池壳体、多个锂电芯以及中空散热器,中空散热器设置在锂电芯与电池壳体的内壁之间,中空散热器具有适形面、流体过流腔、流体入口以及流体出口,适形面与锂电芯的周面配合,外部的冷却流体通过流体入口流入流体过流腔,并自流体出口流出中空散热器,当冷却流体流过适形面时,锂电芯通过适形面传导热量并通过冷却流体持续带走热量。
