Preferably, the shape and size of the first heat dissipation fan body is the same as the shape and size of the second heat dissipation fan body, and the first heat dissipation fan body and the second heat dissipation fan body are symmetrically arranged by taking the perpendicular bisector of the protective shell as the symmetry axis.
Preferably, the shape and size of the insulating layer are matched with those of the lithium battery body, and the insulating layer is a synthetic resin insulating layer.
Preferably, the quantity of bolt is four, and per two bolts be a set of, and two sets of bolts use the perpendicular bisector of top dust screen to set up as symmetry axis symmetry, and the top dust screen is stainless steel top dust screen.
Preferably, the shape and size of the first side heat dissipation holes are the same as those of the second side heat dissipation holes, and the first side heat dissipation holes and the second side heat dissipation holes are symmetrically arranged by taking the perpendicular bisector of the protective shell as a symmetry axis.
Preferably, one end of the bolt penetrates through the top of the top dust screen, the top of the sealing cover and the top of the protective shell respectively and extends into the protective shell, and the shape and the size of the sealing cover are matched with those of the protective shell.
Preferably, the shape and size of first side dust screen is the same with the shape and size of second side dust screen, and first side dust screen and second side dust screen use the perpendicular bisector of protection shell to set up as symmetry axis symmetry, and first side dust screen and second side dust screen are stainless steel side dust screen.
(III) advantageous effects
Compared with the prior art, the utility model provides a lithium cell that security performance is high possesses following beneficial effect:
1. this lithium cell that security performance is high, through protective housing, heat conduction silica gel layer, first heat dissipation fan body, second heat dissipation fan body, first side louvre, second side louvre, the use of mutually supporting of top louvre and positive louvre, can be at the inside lithium cell body during operation of protective housing, carry out effectual heat dissipation treatment to it, prevent its high temperature and the danger of explosion, improve its security performance, result of use and life obtain improving, can satisfy user's user demand.
2. This lithium cell that security performance is high uses through mutually supporting of first side dust screen, second side dust screen and top dust screen, not only can assist the inside ventilative heat dissipation of protective housing, also can prevent that foreign matters such as dust from getting into protective housing inside, improves its result of use, and the practicality obtains improving.
3. This lithium cell that security performance is high uses through mutually supporting of sealed lid and bolt, can the person of facilitating the use regularly overhaul protective housing internals's behaviour in service, improves its result of use and life, simultaneously, also plays fine protecting effect to the lithium cell body, and the practicality is high, and security performance is good, and user's user demand is satisfied.
