Description
Technical field
This utility model relates to technical field of lithium batteries, is specifically related to a kind of safety heat radiation lithium battery group.
Background technology
Along with the sustainable development of set of cells, especially lithium battery group is more widely deployed for multiple use, and demand is protected for a long time
Hold high-octane safety battery group more and more important.
For lithium battery group, Multisection battery core series and parallel assembles Shortcomings, and original copolymer battery connects combination
There is potentially shorting potential safety hazard afterwards, security performance declines, and can not meet safe design need for producing electrokinetic cell
Asking, service life shortens.Current lithium battery group major part is to rivet after aluminum, nickel lug overlap joint, causes internal resistance high, safeguards not
Convenient, the lug of battery easily loosens, fracture, and security performance is the poorest, is not easy to heat radiation after entire package.
To this end, the patent of the Publication No. of the applicant's earlier application " 203386836U " discloses a kind of lithium ion power
Set of cells, this kind of lithium-ion-power cell group overcome the direct series and parallel of Multisection battery core and assemble the deficiency existed, it is to avoid short
Road hidden danger, improves security performance；But its technical scheme solving lithium battery group heat dissipation problem is to offer heat radiation at wall box
Hole, the radiating effect that this technical scheme shows in practice is unsatisfactory, and it does not possess temperature pre-warning function.
Summary of the invention
This utility model is to solve the technical deficiency that earlier application exists, it is provided that a kind of safety heat radiation lithium battery group.
This utility model is achieved by the following technical solution:
A kind of safety heat radiation lithium battery group, includes the two or more lithium battery being positioned at casing, passes through between lithium battery
Sponge double faced adhesive tape separates and fixes, and casing top is pcb board, and the electrode of lithium battery passes through wire connecting PCB board, and its feature exists
In: the side of described lithium battery is provided with longitudinal heat dissipation wind channel, and the upper and lower end of described casing is provided with corresponding with this heat dissipation wind channel
Honeycomb briquet-bulk hot hole.
The opposite side of described lithium battery is provided with recess and connects recess and longitudinally disposed holding wire passage, in described recess
Temperature sensor is installed, described temperature sensor by the processor on holding wire connecting PCB board, described holding wire through
In holding wire passage, the processor on described pcb board connects to be had alarm device and is provided with alarm threshold value.
Described heat dissipation wind channel has arc section.
Described recess is positioned at 1/3～2/3 height and position of lithium battery.
Described recess is positioned at 1/2 height and position of lithium battery.
The beneficial effects of the utility model are: one is to improve security performance, make the lug of lithium battery be difficult to loosen, break
Splitting, shake-proof ability is strong；Two is the radiating effect being improved lithium battery group by structure design, and by temperature sensor, place
The setting of reason device and alarm device achieves lithium battery temperature pre-warning function.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described.
Fig. 1 is the longitudinal cross-section schematic diagram of this utility model structure.
Fig. 2 is the transverse sectional view of this utility model structure.
In figure, 1 casing, 2 lithium batteries, 3 pcb boards, 4 heat dissipation wind channels, 5 recesses, 6 temperature sensors, 7 holding wire passages, 8
Holding wire, 9 honeycomb briquet-bulk hot holes.
Detailed description of the invention
Being a kind of specific embodiment of the present utility model as shown in Figure 1, 2, this embodiment includes
There is the two or more lithium battery 2 being positioned at casing 1, separated by sponge double faced adhesive tape between lithium battery and fix, case
Body top is pcb board 3, and the electrode of lithium battery passes through wire connecting PCB board, it is characterised in that: the side of described lithium battery is provided with
Longitudinal heat dissipation wind channel 4, the upper and lower end of described casing is provided with the honeycomb briquet-bulk hot hole 9 corresponding with this heat dissipation wind channel.
Further, the opposite side of described lithium battery is provided with recess 5 and connects recess and longitudinally disposed holding wire passage 7,
Being provided with temperature sensor 6 in described recess, described temperature sensor is by the processor on holding wire 8 connecting PCB board, described
Holding wire is through in holding wire passage, and the processor on described pcb board connects to be had alarm device (not shown) and arrange
There is alarm threshold value.Temperature sensor senses lithium battery temperature the processor that temperature data is sent on pcb board, processor is certainly
Move and judge whether temperature exceedes the alarm threshold value of setting, control alarm device when exceeding alarm threshold value and send alarm signal.
Further, described heat dissipation wind channel has arc section.
Further, described recess is positioned at 1/3～2/3 height and position of lithium battery.
Further, described recess is positioned at 1/2 height and position of lithium battery, this position can at utmost avoid two ends into and out of
The air-flow impact on temperature sensor measurement accuracy.
