Mechanism.First is that, when the temperature in battery rises, its resistance value rises with it using switch element, it when the temperature is excessively high, can be certainly
It is dynamic to stop power supply；Second is that separator material appropriate is selected, the micron order micropore meeting when temperature rises to certain numerical value, on partition
Automatic dissolving is taken off, to prevent lithium ion from passing through, inside battery reaction stops；Third is that setting safety valve (is exactly battery top
Air vent), when cell internal pressure rises to certain numerical value, safety valve is automatically opened, and guarantees the safety in utilization of battery.
Sometimes, although lithium battery itself there are safety control measures, because certain reasons cause control failure, lack peace
Full valve or gas have little time to discharge by safety valve, and lithium battery internal pressure will steeply rise and set off an explosion.
Under normal circumstances, the gross energy of lithium battery storage and its safety are inversely proportional, with the increase of battery capacity,
A possibility that lithium battery volume is also increasing, and heat dissipation performance is deteriorated, and accidents happened will be significantly increased.For mobile phone lithium battery,
Basic demand is that the probability of generation safety accident is less than hundred a ten thousandths, this is also the receptible lowest bid of public institute
It is quasi-.And for the high capacity lithium ion battery such as high-capacity lithium battery, especially automobile, it is particularly important using forced heat radiation.
Lithium battery kit is relatively conventional lithium battery accommodating container, and heat dissipation performance is also particularly important.Relatively simple heat dissipation
Mode be respectively set on four walls of lithium battery kit in laterally or longitudinally arrange multiple strips, circle or other shapes or
The thermal vias of structure, by the diffusion way of heat from-inner-to-outer to have the function that Temperature fall, although this heat dissipation side
Formula effect is preferable, but the dust in the external world, humid air even rainwater easily enter in lithium battery kit, to influence lithium battery
Service life.
Utility model content
The purpose of the utility model is to provide a kind of lithium battery kit cooling mechanisms, can carry out by condition of different temperatures in box body

The technical solution of the utility model is as follows:
A kind of lithium battery kit cooling mechanism, includes box body, and four walls of the box body are respectively equipped with long stripes through hole, special
Sign is: being rotatably equipped with the baffle that can be overturn in vertical plane in the long stripes through hole respectively, sets on the baffle
There are multiple airing holes, is respectively corresponded above the long stripes through hole on the inner wall of the box body and motor is installed, institute
The output shaft for stating motor is laterally extended respectively and is separately installed with runner, the eccentric position of the runner in corresponding baffle
Connecting rod is rotatably connected between the upper end of side；Temperature sensor and controller, the control are respectively arranged in the box body
On the one hand device processed is connected with the temperature sensor, be on the other hand connected respectively with the motor.
The lithium battery kit cooling mechanism, it is characterised in that: being connected separately with section around the surrounding of each baffle is in
Bowed annular seal ring.
The lithium battery kit cooling mechanism, it is characterised in that: the eccentric position of the runner, which is fixedly connected with, laterally to be prolonged
The cross bar stretched, the upper end on the inside of the baffle are fixedly connected with fixing seat, and the connecting rod in vertically arranged, distinguish by the both ends of connecting rod
It rotates and connect with the front end of the cross bar and the fixing seat.
The lithium battery kit cooling mechanism, it is characterised in that: the motor uses stepper motor.
The lithium battery kit cooling mechanism, it is characterised in that: the controller uses single-chip microcontroller.
The utility model has the beneficial effects that
The utility model structure is simple, can carry out difference heat dissipation by condition of different temperatures in box body, dissipates not influencing box body

Device 8 is connected, and is on the other hand connected respectively with stepper motor 5.
In the utility model, it is connected separately with the arched annular seal ring 10 in section around the surrounding of each baffle, is risen
To the effect of the long stripes through hole 2 where sealing.
The eccentric position of runner 6 is fixedly connected with the cross bar 11 being laterally extended, and the upper end of 3 inside of baffle is fixedly connected with
Reservation 12, in vertically arranged, the both ends of connecting rod 7 rotate and connect with the front end of cross bar 11 and fixing seat 12 respectively connecting rod 7.
The utility model is further described below in conjunction with attached drawing:
When 1 internal temperature of box body is not high, baffle 3 is in closed state (in a vertical state, the strip where blocking
Shape through-hole 2), the heat in box body 1 is spread out by multiple airing holes 4 on baffle 3 at this time, slowly radiated, this
Sample just can be avoided extraneous dust, humid air even rainwater enters in box body 1.
When 1 internal temperature of box body is higher, temperature sensor 8 detects temperature signal and is sent to single-chip microcontroller 9, single-chip microcontroller
9 send control command to stepper motor 5, and stepper motor 5 starts work, drive baffle 3 to overturn, make the upper end towards box body 1
Towards the outside of box body 1, such rainwater is not easily accessible in box body 1 for internal, lower end, and long stripes through hole 2 is opened at this time, in box body 1
Heat spread out by long stripes through hole 2, rapid cooling is carried out, quickly to reduce the temperature in box body 1.
Above embodiment is only that the preferred embodiment of the utility model is described, not to the utility model
Protection scope be defined, under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art to this
The modification and improvement that the technical solution of utility model is made should all be fallen into the protection scope of the utility model.
