The embodiment of the invention provides a battery box body, a battery pack and a new energy automobile, and relates to the technical field of power batteries. The battery box comprises a first shell and a second shell, the first shell is provided with a cooling liquid flow channel, the second shell is matched with the first shell to form a containing cavity for containing the battery cell, the second shell is provided with a cooling cavity, the cooling cavity is communicated with the cooling liquid flow channel, and the cooling cavity is used for leaking cooling liquid under the condition that the battery cell is subjected to thermal runaway. And cooling the battery cell which is subjected to thermal runaway. The battery box body can quickly reduce the temperature of the battery cells in thermal runaway, so that the adjacent battery cells do not generate thermal runaway, and the thermal runaway is inhibited from diffusing and spreading in a battery pack.

    本发明的实施例提供了一种电池箱体、电池包及新能源汽车,涉及动力电池技术领域。电池箱体包括第一壳体以及第二壳体,第一壳体设置有冷却液流道,第二壳体与第一壳体配合,以形成用于容纳电芯的容纳腔,第二壳体设置有冷却腔,冷却腔与冷却液流道连通,且冷却腔用于在电芯发生热失控的情况下泄漏冷却液,以对发生热失控的电芯进行冷却降温。该电池箱体能够将热失控的电芯温度迅速降低,使其相邻的电芯不发生热失控,抑制热失控在电池包内扩散蔓延。
