The scheme of installation of a kind of fin for lithium battery protection board that Fig. 2 provides for the utility model;
The side-looking structural representation of a kind of fin for lithium battery protection board that Fig. 3 provides for the utility model.
In accompanying drawing, the list of parts of each label representative is as follows:
1: base plate; 2: riveting post;
3: internal thread; 4: silica gel piece;
5: lithium battery protection board.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below the utility model execution mode is described in further detail.
In order to improve area of dissipation, the heat management of whole lithium battery protection board is effectively improved, the utility model embodiment provides a kind of fin for lithium battery protection board, referring to Fig. 1, Fig. 2 and Fig. 3, comprise: base plate 1, base plate 1 is fixedly installed at least 3 riveting posts 2, is provided with internal thread 3 on riveting post 2, and base plate 1 is fixedly connected with lithium battery protection board 5 by the internal thread 3 on riveting post 2;
The bottom of base plate 1 is provided with several silica gel pieces 4, and silica gel piece 4 is arranged on the electric discharge metal-oxide-semiconductor and equalizing resistance of lithium battery protection board 5, and after assembling, elastic deformation occurs silica gel piece 4.
During actual use, silica gel piece 4 is fixed on the bottom of base plate 1 by binding agent, and silica gel piece 4 is padded on electric discharge metal-oxide-semiconductor and equalizing resistance, has prevented that base plate 1 from directly contacting with lithium battery protection board 5 components and parts that damage on lithium battery protection board 5.The quantity of silica gel piece 4 determined by the number of discharge metal-oxide-semiconductor and equalizing resistance, and the utility model embodiment be take 3 silica gel pieces 3 and described as example, and during specific implementation, the utility model embodiment does not limit this.
In a preferred embodiment, in order to improve radiating effect, the size of silica gel piece 4 preferably matches with the size of electric discharge metal-oxide-semiconductor and equalizing resistance.
Wherein, the shape of the shape of base plate 1 and lithium battery protection board 5 matches, for example: the metal-oxide-semiconductor that conventionally discharges is higher than equalizing resistance; in order to coordinate; base plate 1 be shaped as back segment lower than leading portion, as " tiltedly Z " type, between leading portion and back segment, there is the base plate 1 of the gradient in shape.Referring to Fig. 2, at the leading portion of base plate 1, be provided with 1 silica gel piece 4, this silica gel piece 4 coordinates with electric discharge metal-oxide-semiconductor; Back segment at base plate 1 is provided with 1 silica gel piece 4, and this place's silica gel piece 4 coordinates with equalizing resistance.In practical application, the shape of base plate 1 is along with the global shape of lithium battery protection board 5 changes and correspondingly converts, and the utility model embodiment does not limit this.
In order to expand the scope in practical application, the material of fin can be aluminium alloy, aluminium, iron or copper.The quantity of riveting post 2 is generally 3-6, and is evenly arranged on base plate 1 bottom, and the utility model embodiment take 3 riveting posts 2 to describe as example, and during specific implementation, the utility model embodiment does not limit this.
