All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The air-cooled battery pack provided by the embodiment of the application is described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.

Referring to fig. 1, the embodiment of the application provides an air-cooled battery pack, which comprises a case body 1, a battery module 2 and a fan 3, wherein the case body 1 comprises a bottom case 11 and a case cover 12 covering the bottom case 11 to form a storage space 10, the bottom case 11 comprises side walls 111 connected end to end, and ventilation holes 1111 which are communicated with the storage space 10 and the external space are formed in the side walls 111 in a penetrating manner.

The battery module 2 is accommodated in the accommodation space 10 and is spaced apart from the side wall 111, so that heat dissipation of the battery module 2 is performed through the vent hole 111.

The number of the battery modules 2 is at least two, and an air duct structure 20 is formed between two adjacent battery modules 2 at intervals.

The battery module 2 comprises a plurality of batteries 21 and a harmonica tube 22 which is clamped between two adjacent batteries 21 and is communicated with the air duct structure 20.

The structure of the harmonica pipe 22 is shown in fig. 2-4, which is a hollow sheet-shaped section, and the material can be selected from materials with excellent heat conduction performance, such as aluminum, copper, etc., and the cross-sectional shape of the harmonica pipe 22 is not limited to the two shown in fig. 3 and 4, and other possible structures are possible.

The fan 3 is mounted on the case 1 and blows or draws air into the air duct structure 20, and because the air duct structure 20 is communicated with the harmonica tube 22, heat generated by the battery 21 can be dissipated into the air duct structure 20 through the harmonica tube 22, and then dissipated to the outside of the case 1 through the air duct structure 20.

In some embodiments, the number of the battery modules 2 is two, the two battery modules 2 are arranged in parallel, and the two battery modules 2 are fixed by the bracket 4 to form an integral structure.

The batteries 21 are arranged in an array along the longitudinal direction of the battery module 2.

The air-cooled battery pack further includes a battery management system 5 mounted on the case 1 to detect a battery temperature.

The embodiment of the application provides an air-cooled battery pack, which has the following working principle:

when the battery management system 5 detects that the temperature of the battery 21 reaches the starting value, the fan 3 starts exhausting, the temperature of the battery 21 is transmitted to the harmonica tube 22 between the electric cores, and then the heat is brought out of the box body 2 through the air duct structure 20, so that the temperature of the battery module 2 is reduced.

The embodiments of the present application have been described above with reference to the accompanying drawings, but the present application is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many forms may be made by those of ordinary skill in the art without departing from the spirit of the present application and the scope of the claims, which are also within the protection of the present application.
