Specific embodiment

It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.

A kind of a kind of embodiment: the lithium ion as shown in Figure 1-3, the utility model provides technical solution, under the influence of electricity Battery thermal stability radiator, including annular slab 1 are welded at each corner position in 1 bottom end of annular slab in a manner of central symmetry Mounting plate 2, through being equipped with motor 3,3 model FF180 of motor, the input terminal and lithium ion battery of motor 3 in the middle part of mounting plate 2 Output end be electrically connected, 3 one end of motor be equipped with three leaves fan 4.

Corresponding three leaves in 1 bottom end of annular slab fan 4 sides and are symmetrically welded with otic placode 5, are rotatably connected to connection between two otic placodes 5 Axis 6,6 middle part outer surface of connecting shaft are welded with wind direction adjusting plate 7, and the splicing of 7 top surface one end of wind direction adjusting plate has reset bullet Property band 8, connection is glued in 8 other end of Flexible Reset band and 1 bottom end of annular slab.

1 top of annular slab corresponds at 7 top surface the other end position of wind direction adjusting plate through adjusting screw hole 9 is offered, and adjusts Section 9 inner rotation of screw hole, which is connected with, adjusts bolt 10.

1 center bottom of annular slab is welded with connecting upright pole 11,11 bottom end of connecting upright pole, one side surface in a manner of central symmetry Be welded with support rail 12, connecting upright pole 11 and 12 quantity of support rail are disposed as four, 12 one end of support rail with it is another A 12 side surface of support rail is welded to connect, so that connecting two-by-two between support rail 12, is effectively supported lithium ion battery and is lifted It rises, is mounted on handle 13 in the middle part of 1 four side surface of annular slab.

Edge is welded with retention mechanism 14 in 1 top of annular slab, and retention mechanism 14 includes fixed block 1401, clamps screw hole 1402, clamping screw 1403, rubber cushion blocks 1404, power-assisted hole 1405, assister bar 1406 and limited block 1407；

Edge is welded with fixed block 1401 in 1 top of annular slab, and 1401 middle part of fixed block is equidistant through offering clamping Screw hole 1402 clamps and is connected with clamping screw 1403 by screw thread engagement inside screw hole 1402, and 1403 one end of clamping screw is glued There are rubber cushion blocks 1404, rubber cushion blocks 1404 are round estrade, and 1,404 1 side surface of rubber cushion blocks offers anti-skid chequer, improve rubber The contact area of cushion block 1404 and casing of lithium ion battery, and the roughness of contact surface is improved, and then realize that raising is quiet between the two Friction coefficient, so that static friction force is bigger, 1403 other end of clamping screw offers power-assisted hole 1405, in power-assisted hole 1405 Portion slidably connects assister bar 1406, and 1406 both ends of assister bar, which are glued, limited block 1407,1406 overall diameter of assister bar and helps 1405 interior diameter of power hole mutually agrees with, and the overall diameter of limited block 1407 is greater than 1405 interior diameter of power-assisted hole, enables assister bar 1406 The case where being slided in power-assisted hole 1405, preventing assister bar 1406 from falling by limited block 1407.

The working principle and process for using of the utility model: the thermal stability of lithium-ion batteries under the influence of the electricity, which radiates, to be filled It sets in use, the hollow space that lithium ion battery passes through annular slab 1 is placed on support rail 12 first, then using fastening Mechanism 14 guarantees the relatively stable of annular slab 1 and casing of lithium ion battery, and retention mechanism 14 in use, pass through power-assisted hole first 1405 pull assister bars 1406, so that the limited block 1407 of 1406 one end of assister bar blocks power-assisted hole 1405, assister bar at this time 1406 extension elongation longests, torque is maximum when rotation, rotates assister bar 1406 at this time, and clamping screw 1403 is driven to rotate, rotation When 1406 position of assister bar person's hand inconvenient to use is held in the process, assister bar 1406 can be slid into along power-assisted hole 1405 The other side arrived power-assisted hole 1405 and remain that long torque is laborsaving so that another limited block 1407 blocks power-assisted hole 1405 Effect, clamping screw 1403 rotate when clamp screw hole 1402 screw thread engagement under moved so that rubber Cushion block 1404 and casing of lithium ion battery fitting, and squeeze casing of lithium ion battery, with the continuous feeding of clamping screw 1403, Its extruding force constantly increases, and static friction force between the two also persistently increases, and then ensure that annular slab 1 without larger external force Under the action of be fitted on the outside of lithium ion battery always, be not in fall and opposite the case where shaking, avoid transporting or carry The shaking of lithium ion battery leads to the damage of annular slab 1 in the process；

In lithium ion battery charge and discharge process, when both the lithium ion battery under the influence of electricity generates heat, motor 3 is connect Enter the output electrode of lithium ion battery, so that motor 3 starts after being powered, so that motor 3 drives three leaves fan 4 to be rotated, three leaves The air-flow that 4 rotation of fan generates blows over the side surface of lithium ion battery, and then drives the air flowing of lithium ion battery side surface, makes The air that obtaining the heat that lithium ion battery generates can continue and flow carries out heat exchange, and then improves heat exchanger effectiveness, so that The hot heat dissipation effect of lithium ion battery is promoted, while in radiation processes, can be rotated and be adjusted bolt 10, is adjusted bolt 10 and is adjusted Threaded function in section screw hole 9 moves down, so that work of the air-flow of three leaves fan, 4 rotation generation by wind direction adjusting plate 7 With blowing downwards, so that the air near bottom part of lithium-ion battery is also flowed, the feelings for avoiding bottom air flow rate slow Condition, adjust bolt 10 squeeze wind direction adjusting plate 7 when, 7 end of wind direction adjusting plate installation Flexible Reset band 8 think always on pull wind To adjustable plate 7, and then the stabilization being effectively ensured in 7 use process of wind direction adjusting plate.

Finally, it should be noted that being not limited to this reality the foregoing is merely the preferred embodiment of the utility model With novel, although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, should all It is included within the scope of protection of this utility model.
