Abstract
The invention discloses a lithium battery pack housing which comprises a metal inner layer, wherein the outside of the metal inner layer is coated with an impact-resistant, insulating and heat-insulating three-dimensional mesh outer layer, and a heat exchange device which is used for carrying out heat exchange with outside to control the temperature inside a battery pack is arranged between the three-dimensional mesh outer layer and the metal inner layer. The lithium battery pack housing has the advantages that when the lithium battery pack is impacted and vibrated, the three-dimensional mesh outer layer can well absorb an external impact, so that the impact resistance of the housing is enhanced, and the impaction can not be directly transmitted to the inside of the lithium battery pack; the outside of the metal inner layer is coated with the three-dimensional mesh outer layer so that the metal inner layer can be prevented from cracking to play a role of insulation protection.
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 comprised of the battery unit in housing and housing.The shortcoming of this lithium ion battery bag is: housing earthquake and shock are lower easily damaged, poor to the buffer capacity of collision.Because housing common metal material is made, after housing breaks, easily contact with battery unit, and cause between battery unit being short-circuited, and damage battery unit.
In order to overcome the poor shortcoming of buffer capacity of housing, Chinese patent ZL200820047961.8 has disclosed a kind of storage battery, and this storage battery comprises housing, and at least one sidewall of housing is provided with cavity.Utilize cavity to come damp impacts and concussion.The shortcoming of this storage battery is: once housing is acutely clashed into and ftractures, cannot stop the extension in crack; And after housing cracking, battery unit directly exposes, and battery unit easily contacts with housing simultaneously, causes being short-circuited between battery unit, damages power brick.
Summary of the invention
The invention provides the lithium battery incrustation that a kind of shock resistance is good, prevent housing cracking and perfect heat-dissipating.
The technical solution used in the present invention is:
A kind of lithium battery incrustation, it is characterized in that: comprise a metal internal layer, the outside of described metal internal layer is coated with one deck shock resistance, insulation and adiabatic three-dimensional netted skin, is provided with the external world and carries out the heat-exchanger rig that power brick internal temperature is controlled in heat exchange between described three-dimensional netted skin and metal internal layer.The three-dimensional netted skin of outer setting one deck at metal internal layer; when lithium battery bag is clashed into and shakes, three-dimensional netted skin has been protected metal internal layer well, weakens the dynamics that it is subject to external impacts; can prevent its cracking, improve the security performance of lithium battery bag.
Further, described heat-exchanger rig comprises the pipeline that circulation arranges, and the initiating terminal of described pipeline is air inlet (liquid) mouthful, and its end is give vent to anger (liquid) mouthful.Extraneous air mouthful is entered through air inlet (liquid), from give vent to anger (liquid) mouthful, discharges, and by the heat absorption in lithium battery bag and take out of, thereby has solved shell with the insulating outer layer bad problem of dispelling 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 has well played the effect of a buffering, absorbs well external impact, and the impulsive force that metal internal layer is subject to weakens, and well prevents metal internal layer cracking.
Further, described lamina reticularis is along horizontal longitudinal arrangement, to be formed respectively by the stem stem of 8-shaped.This kind of lamina reticularis, when break in three-dimensional netted outer field extexine or endosexine, can play the effect that stops breach to extend, and avoids breach to extend rapidly.
Further, described three-dimensional netted skin is provided in a side of on any outer surface of metal internal layer or on a plurality of outer surfaces of metal internal layer.Most preferably on all outer surfaces of metal internal layer, to be equipped with three-dimensional netted skin.
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 make to impact not directly to be passed to lithium battery bag inside.
2, three-dimensional netted skin is coated on to the outside of metal internal layer, can prevents metal internal layer cracking, play the effect of insulation protection.
When 3, break in three-dimensional netted outer field extexine or endosexine, the lamina reticularis in the middle of it plays the effect that stops 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 the present invention contained all alternatives, improvement project and the equivalents that within the scope of claims, may comprise.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of lithium battery incrustation, comprise a metal internal layer 1, the outside of described metal internal layer 1 is coated with between one deck shock resistance, insulation and adiabatic three-dimensional netted outer 3, described three-dimensional netted outer 3 and metal internal layer 1 and is provided with the heat-exchanger rig 2 that carries out heat exchange control power brick internal temperature with the external world.At outer setting one deck of metal internal layer 1 three-dimensional netted outer 3; when lithium battery bag is clashed into and shakes, three-dimensional netted outer 3 have protected metal internal layer 1 well, weaken the dynamics that it is subject to external impacts; can prevent its cracking, improve the security performance of lithium battery bag.
Described heat-exchanger rig 2 comprises the pipeline 21 that circulation arranges, and the initiating terminal of described pipeline 21 is air inlets (liquid) mouthful, and its end is give vent to anger (liquid) mouthful.Extraneous air mouthful is entered through air inlet (liquid), from give vent to anger (liquid) mouthful, discharges, and by the heat absorption in lithium battery bag and take out of, thereby has solved shell with the insulating outer layer bad problem of dispelling 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 has well played the effect of a buffering, absorbs well external impact, and the impulsive force that metal internal layer 1 is subject to weakens, and well prevents metal internal layer 1 cracking.
Described lamina reticularis 32 is along horizontal longitudinal arrangement, to be formed respectively by the stem stem of 8-shaped.This kind of lamina reticularis 32, when break in three-dimensional netted outer 3 extexine 33 or endosexine 31, can play the effect that stops breach to extend, and avoids breach to extend rapidly.
