Abstract
The present invention provides a kind of lithium battery assembly housing.The shell is made of trilaminate material, and inside and outside two layers is insulating refractories, and intermediate layer is the light-duty carbon material of high intensity high heat conduction, and the shell is both provided with radiating fin inside and outside housing.The shell is using light-duty carbon material as main material, light weight, and intensity is high, and thermal diffusivity is good, easy to process.
Description
Technical field
The present invention relates to field of lithium, especially a kind of lithium battery assembly housing.
Background technology
As China's economic development and process of industrialization are accelerated, a series of environmental problem emerges in succession, the energy
Crisis and environmental pollution also become the important contradiction for restricting China's development, therefore, readjust the energy structure, and promote energy storage technology wound
Newly have become state key development strategy.At present, lithium ion battery is because of its excellent high-energy, high circulation service life, wide work
Warm area and low self-discharge performance and be widely used in all trades and professions, lithium ion battery be the most important technology in energy storage field it
One, it is widely used in photovoltaic generation and electric automobile field.
At present, the structure of the lithium ion battery bag of in the market is：Lithium ion battery bag is by the battery list in housing and housing
Member composition.The shortcomings that this lithium ion battery bag is：Housing earthquake and shock are lower easily damaged, to the buffer capacity of collision
Difference.Since housing common metal material is made, easily contacted after casing rupture with battery unit, and cause to send out between battery unit
Raw short circuit, and damage battery unit.The radiating mode used during work is mainly air cooling, but the heat convection system of air
Smaller, the heat transfer effect unobvious of number, lithium battery can produce heat in charge and discharge process because of electrochemical reaction and material transmission,
If these heats are not discharged and largely accumulated in time, battery temperature rising can be further resulted in, reaction is accelerated, and influences the battery longevity
Life, once running into the situation that some battery core temperature steeply rises, can not ensure the safety of battery pack entirety.
The content of the invention
The purpose of the present invention, is to solve the above problem existing in the prior art, there is provided a kind of
Lithium battery assembly housing.
The present invention makes lithium battery assembly housing by main system of light-duty carbon material, is used absolutely for two layers inside and outside shell
Edge refractory material is adhered to, and radiating fin is machined with inside and outside housing.
The light-duty carbon material is made after dipping for matrix carbon plate.
The insulating refractories is fire retarding epoxide resin or Flame-retardant acrylonitrile-butadiplasticrene copolymer.
The radiating fin is uniformly distributed in inside and outside four walls of shell.
The impregnating agent that the dipping uses is thermoplastic resin or thermosetting resin.
The thermoplastic resin includes polypropylene, polyamide, polyester, fluoropolymer, Kynoar, polyphenylene sulfide
Ether, polyetherimide, polyether-ether-ketone, polyether ketone ketone or polyether sulphone etc..
The thermosetting resin includes vinylester resin, phenolic resin, epoxy resin or sulphone resin etc..
The beneficial effect that the present invention realizes：
Light-duty carbon material after lithium battery assembly housing of the present invention is impregnated as a result of resin is main body, thus is made whole outer
Shell had not only had higher mechanical strength and excellent, but also had lighter quality, exhausted along with having been used for two layers inside and outside shell
Edge refractory material, so more reduces the adverse effect produced after failure of battery cells, and the inside and outside of housing is machined with
Radiating fin, it is ensured that the timely exclusion of internal heat, avoids steeply rising for internal temperature of battery.

Embodiment
With reference to specific embodiment, the embodiment that the present invention is further explained.It is to be understood that these embodiments are only used for
Illustrate the present invention rather than limit the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, this
Field technology personnel can make various changes or modifications the present invention, and such equivalent forms equally fall within right appended by the application will
Seek book limited range.
Embodiment
Refering to Fig. 1~Fig. 4, the present invention provides a kind of lithium battery assembly housing, this shell includes cladding material 3, middle level
Material of main part 4,5 three parts of inner layer material composition, hull outside are machined with radiating fin 1, and enclosure interior is machined with radiating fin
2。
Specifically, referring to Fig. 1~Fig. 3, base material carbon plate is made through over mechanical processing, processing and is evenly distributed on outer surface of outer cover
Radiating fin 1 and be evenly distributed on the radiating fin 2 of inner surface of outer cover.
As shown in figure 4, after the completion of above-mentioned mechanical processing, the light-duty carbon material shell 4 machined is sprayed
Processing, in the external spray insulating refractories 3 of sheathing material 4, in the internal spray insulating refractories 5 of sheathing material 4.
The radiating fin 1 of the outer surface can be played with the radiating fin 2 of inner surface to be added
The effect of speed heat transmission, the heat dissipation of internal cell is exported to battery pack, avoid internal temperature of battery in time
Steeply rise.
The external spray insulating refractories 3 can play insulated fireproof with internal spray insulating refractories 5
Effect, in the case where internal cell leakage or burning occurs, can prevent the further sprawling of danger.
