Multi-stage cooling new energy automobile battery aluminum shell

The invention relates to the field of new energy automobile batteries, in particular to a multi-stage cooling new energy automobile battery aluminum shell. The technical problems that in the prior art, a device is complex, the protection effect on a battery is poor, and the heat dissipation efficiency of the position in contact with the battery is low are solved. According to the technical scheme, the multi-stage cooling new energy automobile battery aluminum shell comprises a lower shell body, an upper shell body and the like; and the lower shell is detachably connected with an upper shell. Through cooperation of the lower shell and the upper shell, all-around protection of the battery body is realized, then through reduction of contact between the heat dissipation strip I and the battery body and between the heat dissipation strip II and the battery body, preliminary cooling of the battery body is realized, and then the protection plate I and the protection plate II blow air to the side wall of the battery
