The design of deep bead ensures that high-temperature gas discharges downwards, can emit high-temperature gas when electric core takes place the thermal runaway in the battery module, and gaseous emission position is rear side air inlet, front side fan mouth, side shutter. Because the boxes are arranged side by side, the design of the louver ensures that high-temperature gas is discharged downwards and cannot be directly sprayed into the adjacent boxes, and the heat diffusion is prevented.

Preferably, the portable electronic device further comprises reinforcing ribs, the reinforcing ribs are arranged on four corners formed by intersecting the front panel, the rear panel, the left panel and the right panel, and through holes are arranged and designed on the reinforcing ribs. The strengthening rib adopts the through-hole design, when guaranteeing box structural strength, the maximize increases the air flow space.

Preferably, the lower box body further comprises a limiting groove, and the limiting groove is arranged on the bottom plate of the lower box body. The spacing groove can be placed in the accurate position when guaranteeing the module vanning.

Preferably, a movable nut is arranged on the lower bottom plate. The movable nut can effectively offset the fixing influence caused by the manufacturing tolerance of the box body.

Preferably, the two sides of the front panel are provided with fixing blocks, and the fixing blocks are provided with mounting holes. The through hole of fixed block can make things convenient for the box pull, replaces the handle, and this structure reduces the processing cost promptly, can reduce box occupation space again.

Preferably, the portable box further comprises a box body handle, the box body handle is symmetrically arranged on the edge where the left panel and the bottom plate are intersected and the edge where the right panel and the bottom plate are intersected, and the box body handle is designed in an embedded mode. The box handle adopts embedded design, reduces box occupation space.

Therefore, the utility model has the following beneficial effects: (1) in the aspect of heat management, the conventional structural scheme can perform air cooling more effectively and reduce the temperature difference of the battery cell effectively; the negative effects caused by thermal runaway can be effectively reduced in the aspect of coping with the thermal runaway; (2) the assembly is simple and convenient, and the space utilization rate is high; (3) the disassembly is simple, and the later maintenance is convenient.
