Specific embodiment

With reference to the accompanying drawing, the utility model is further illustrated by way of embodiment, but therefore will be originally unpractical It is novel to be limited among following scope of embodiments.

As shown in Figure 1-3, battery 100 includes: shell, mould group 20 and fan 30 set on interior of shell.

Shell includes upper cover 11 and cabinet 12, and upper cover 11 is covered on the upper opening of cabinet 12 so that mould group 20 is wrapped in shell In internal space.

The opposite the first side wall 13 and second sidewall 14 of cabinet 12 is equipped with ventilation hole 15.

Battery 100 includes multiple mould groups 20 arranged side by side.Certainly, selectively, those skilled in the art can also basis It needs, a mould group 20 is only set in the shell.

Mould group 20 includes at least one module 21 arranged in a straight line, in the present embodiment by taking three modules 21 as an example.Certainly, Also it can according to need the quantity of any selecting module 21.

As illustrated in figures 4-5, each module 21 includes the battery core 22 and fixed frame 23 of multiple parallel connections, and fixed frame 23 is with multiple electricity The fixed multiple battery cores 22 of the mode being spaced apart from each other between core 22, the extending direction of battery core 22 is consistent with the orientation of module 21, Interval between multiple battery cores 22 forms air duct, and face is distinguished in two end faces of two end faces of air duct connectivity module 21, mould group 20 To the first side wall 13 and second sidewall 14.

Fan 30 is set between the first side wall 13 and the end face of mould group 20.

The arrangement of battery core 22 in each module 21 is identical, to facilitate the air duct between the battery core 22 in disparate modules 21 It communicates.

Battery core 22 is cylindrical structure.Mould group 20 includes multiple modules 21, and multiple modules 21 are serially connected.

The first side wall 13 and second sidewall 14 are parallel to each other, and battery core 22 is along the direction extension perpendicular to the first side wall 13.
