The invention discloses a battery pack protection device for a new energy automobile and a new energy automobile battery. The device comprises a protection device body, a supporting frame and an upper cover, an air inlet pipe is fixedly connected to the bottom end of the outer wall of one side of the protection device body, and an air filtering pipe is detachably connected to the end, away from the protection device body, of the air inlet pipe; the bottom end of the outer wall of one side of the protection device body is fixedly connected with an exhaust pipe. Heat can be transmitted to cooling liquid in the heat dissipation plate through the heat dissipation plate, temperature emitted by the battery pack can be transmitted to the upper cover along with air and then transmitted to the mounting plate through the heat conduction plate, heat on the mounting plate can be absorbed by the heat conduction rods, and then the heat is dissipated to external air through the heat dissipation rods on the heat conduction rods. And external cooling air can be guided into the protection device body through the air filtering pipe, so that the battery pack in the protection device body is cooled.

    本发明公开了一种新能源汽车用电池包防护装置及新能源汽车电池,包括:防护装置本体、支撑框架和上盖,所述防护装置本体一侧外壁底端固定连接有进风管,所述进风管远离所述防护装置本体的一端可拆卸连接有滤风管,所述防护装置本体一侧外壁底端固定连接有排风管;热量会通过散热板传递到其内部的冷却液中,而且电池包发出的温度会随着空气传递到上盖上,然后通过导热板传递到安装板上,安装板上的热量会被导热棒所吸收,然后通过导热棒上的散热棒把热量散发到外部的空气中去,而且通过滤风管能够将外部的冷却风导入到防护装置本体内,从而对防护装置本体内的电池包进行散热。
