Abstract
The invention relates to a lithium battery pack case. The case comprises a metal inner layer, wherein the metal inner layer is covered with a shock-resistant, insulating and heat-insulating three-dimensional net outer layer, and a heat exchange device having heat exchange with the outside to control the internal temperature of a battery pack is arranged between the three-dimensional net outer layer and the metal inner layer. The lithium battery pack case has the advantages as follows: when the lithium battery pack is collided and shocked, the three-dimensional net outer layer can well absorb external shocks, enhance shock resistance of the case and prevent the shocks from directly being transmitted into the lithium battery pack; the three-dimensional net outer layer covers the metal inner layer to prevent the metal inner layer from cracking and play an insulation protection role.
Description
Technical field
The present invention relates to a kind of lithium battery incrustation.
Background technology
At present, the structure of the lithium ion battery bag on market is: lithium ion battery bag is made up of the battery unit in housing and housing.The shortcoming of this lithium ion battery bag is: housing earthquake and easily breakage under clashing into, poor to the buffer capacity of collision.Because housing common metal material is made, easily contact with battery unit after casing rupture, and cause being short-circuited between battery unit, and damage battery unit.
In order to overcome the shortcoming of the buffer capacity difference of housing, Chinese patent ZL200820047961.8 discloses a kind of storage battery, and this storage battery comprises housing, and at least one sidewall of housing is provided with cavity.Cavity is utilized to come damp impacts and concussion.The shortcoming of this storage battery is: once housing is ftractureed by hard hit, cannot stop the extension in crack; And battery unit directly exposes after housing cracking, simultaneously battery unit easily and body contact, causes being short-circuited between battery unit, damage power brick.
Summary of the invention
The invention provides a kind of shock resistance good, prevent housing ftracture and the lithium battery incrustation of perfect heat-dissipating.
The technical solution used in the present invention is:
A kind of lithium battery incrustation, it is characterized in that: comprise an inner metallic layer, the outside of described inner metallic layer is coated with the three-dimensional netted skin of one deck shock resistance, insulation and thermal insulation, is provided with and carries out with the external world heat-exchanger rig that heat exchange controls power brick internal temperature between described three-dimensional netted skin and inner metallic layer.At the three-dimensional netted skin of outer setting one deck of inner metallic layer; when lithium battery bag is clashed into and shakes, three-dimensional netted skin protects inner metallic layer well, weakens the dynamics that it is subject to external impacts; can prevent it from ftractureing, improve the security performance of lithium battery bag.
Further, described heat-exchanger rig comprises the pipeline be circularly set, and the initiating terminal of described pipeline is air inlet (liquid) mouth, and its end is (liquid) mouth of giving vent to anger.Extraneous air is entered through air inlet (liquid) mouth, and from giving vent to anger, (liquid) mouth is discharged, and the heat absorption in lithium battery bag is taken out of, the bad problem thus the shell solved with insulating outer layer dispels the heat.
Further, described three-dimensional netted skin comprises endosexine and extexine, and the centre of described endosexine and extexine is provided with and connects all-in-one-piece lamina reticularis.When lithium battery bag is clashed into and shakes, lamina reticularis well serves the effect of a buffering, and absorb external impact well, the impulsive force that inner metallic layer is subject to weakens, and well prevents inner metallic layer from ftractureing.
Further, described lamina reticularis distinguishes transversely longitudinal arrangement by the stem stem of 8-shaped to be formed.This kind of lamina reticularis, when three-dimensional netted outer field extexine or endosexine break, can play the effect stoping breach to extend, avoid breach to extend rapidly.
Further, described three-dimensional netted skin be located at inner metallic layer any outer surface on or inner metallic layer multiple outer surfaces on.Most preferably be equipped with three-dimensional netted skin on all outer surfaces of inner metallic layer.
Beneficial effect of the present invention:
1, when lithium battery bag is clashed into and shakes, three-dimensional netted skin can absorb external impact well, strengthens the resistance to impact of shell and makes impact directly can not be passed to lithium battery bag inside.
2, by the outside of three-dimensional netted external sheath at inner metallic layer, can prevent inner metallic layer from ftractureing, play the effect of insulation protection.
3, when break in three-dimensional netted outer field extexine or endosexine, the lamina reticularis in the middle of it plays the effect stoping breach to extend, and avoids breach to extend rapidly.

Embodiment
Below in conjunction with specific embodiment, the present invention is further described, but does not limit the invention to these embodiments.One skilled in the art would recognize that all alternatives, improvement project and the equivalents that present invention encompasses and may comprise in Claims scope.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of lithium battery incrustation, comprise an inner metallic layer 1, the outside of described inner metallic layer 1 be coated with one deck shock resistance, insulation and thermal insulation three-dimensional netted outer 3, be provided with between described three-dimensional netted outer 3 and inner metallic layer 1 and carry out with the external world heat-exchanger rig 2 that heat exchange controls power brick internal temperature.At outer setting one deck of inner metallic layer 1 three-dimensional netted outer 3; when lithium battery bag is clashed into and shakes, three-dimensional netted outer 3 protect inner metallic layer 1 well, weaken the dynamics that it is subject to external impacts; can prevent it from ftractureing, improve the security performance of lithium battery bag.
Described heat-exchanger rig 2 comprises the pipeline 21 be circularly set, and the initiating terminal of described pipeline 21 is air inlet (liquid) mouths, and its end is (liquid) mouth of giving vent to anger.Extraneous air is entered through air inlet (liquid) mouth, and from giving vent to anger, (liquid) mouth is discharged, and the heat absorption in lithium battery bag is taken out of, the bad problem thus the shell solved with insulating outer layer dispels the heat.
Described three-dimensional netted outer 3 comprise endosexine 31 and extexine 33, and the centre of described endosexine 31 and extexine 33 is provided with and connects all-in-one-piece lamina reticularis 32.When lithium battery bag is clashed into and shakes, lamina reticularis 32 well serves the effect of a buffering, and absorb external impact well, the impulsive force that inner metallic layer 1 is subject to weakens, and well prevents inner metallic layer 1 from ftractureing.
Described lamina reticularis 32 distinguishes transversely longitudinal arrangement by the stem stem of 8-shaped to be formed.This kind of lamina reticularis 32, when the three-dimensional netted extexine of outer 3 33 or endosexine 31 break, can play the effect stoping breach to extend, avoid breach to extend rapidly.
Described three-dimensional netted outer 3 be located at inner metallic layer 1 any outer surface on or inner metallic layer 1 multiple outer surfaces on.Most preferably be equipped with three-dimensional netted skin on all outer surfaces of inner metallic layer.
