Description
Technical field
The present invention relates to batteries of electric automobile field, more particularly to a kind of Li-ion batteries piles of energy Homogeneouslly-radiating.
Background technology
The cooling system of electric automobile affects the energy consumption of electric automobile and the service life of equipment, wherein, influence larger
It is the battery of electric automobile.The existing battery for using of electric automobile includes lead-acid battery, lithium ion battery, sodium-sulphur battery and NI-G
Battery, wherein, have that lightweight, energy storage is big, power is big due to lithium ion battery, it is pollution-free the features such as, it is now wide progressively to replace
The general lead-acid battery for using.But, because lithium ion battery temperature influence is larger, excessive temperature easily makes battery electrolyte point
Solution, causes battery early ageing, while can also cause battery charging and discharging unbalanced.Therefore, the electronic vapour of existing use lithium ion battery
Che Douhui sets cooling system, and carries out forced ventilation.
When the battery core temperature of Li-ion batteries piles reaches more than 45 DEG C, battery core in repid discharge state, and will not reach
Battery core to the temperature still in regular picture state, repeatedly after, service life and property in repid discharge state battery core
To can go down significantly, the performance of battery pack is also by the design requirement and target at the initial stage of not reaching.Existing battery pack structure and sky
The contact area of gas is less, its purpose that can not reach rapid radiating, is radiated simultaneously for single battery core not enough, and it is easily led
Hot-spot phenomenon is caused, and then prevents battery pack from reaching the effect of Homogeneouslly-radiating.
The content of the invention
Goal of the invention of the invention is：For above-mentioned problem, there is provided a kind of lithium-ion electric of energy Homogeneouslly-radiating

Ground radiates to single battery core, battery pack is reached the purpose of Homogeneouslly-radiating on the whole.
The technical solution adopted by the present invention is as follows：It is a kind of can Homogeneouslly-radiating Li-ion batteries piles, including shell, shell by
The Access Division for fixing battery core of multiple parallel connected arrays is constituted, and the gap between adjacent Access Division forms heat dissipation channel, clamping
Portion includes constituting the straight flange of housing exterior profile and constitutes the elastic edge of heat dissipation channel, and elastic edge is located at the both sides of straight flange and is certainly
Integrally formed Access Division, elastic edge is in bending, and in same Access Division, it is accordingly opposite between elastic edge to bend with solid
Surely the battery core in Access Division is inserted.
Due to the setting of said structure, Access Division connects and fixes battery core, when battery core inserts Access Division, the elasticity of Access Division
Side outwards expands, and then elastic edge is in close contact with battery core by elastic reaction, while fixed battery core, can inhale very well
Receive the thermal energy on battery core surface, and externally radiate by heat dissipation channel simultaneously, and then realize quickly timely thermolysis,
On the whole, the radiating of each battery core tends to uniform, and temperature tends to identical, has reached the purpose of Homogeneouslly-radiating.
Further, connected by elastic edge between adjacent Access Division, elastic edge junction is by arc transition and forms drum
Shape heat dissipation channel, Access Division is symmetric along the axis parallel to straight flange.Such setting can very well fix battery core, and
Simultaneously beneficial to the formation of heat dissipation channel, it is easier single battery core radiating.
Further, its maximum width of heat dissipation channel is located at the middle part of Access Division, and the arc sections of relative Access Division divide it
Between spacing not less than shell most bond length 1/6.
As a kind of alternative, it is fixedly connected by straight flange between adjacent Access Division, it is adjacent between adjacent Access Division
Elastic edge is bent to form cydariform heat dissipation channel.
Further, the minimum widith of Access Division is more than the Breadth Maximum of heat dissipation channel, to distinguish Access Division and heat dissipation channel,
Prevent operating personnel from recognizing mistake and the situation of setup error occur, furthermore, fix bar is provided with heat dissipation channel, Gu
The two ends of fixed pole are fixedly connected on elastic edge, and the setting of fix bar can not only fix Access Division, prevent Access Division from rocking strict
Stability that is harmful and influenceing battery pack, meanwhile, when operating personnel install heat dissipation channel as Access Division by mistake, due to fix bar
Setting, battery core will be unable in fully-inserted heat dissipation channel, and then avoid the situation that the mistake of operating personnel installs completely.
Further, preferably, elastic edge is elastic sheet metal, its thickness is 0.1-0.8mm, furthermore, bullet
Property sheet metal can be stainless steel metal piece, or Al-alloy metal piece, also or other metal materials sheet metal.
In sum, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：When battery core inserts Access Division
When, the elastic edge of Access Division outwards expands, and then elastic edge is in close contact with battery core by elastic reaction, in fixed battery core
Meanwhile, with the thermal energy on good absorption battery core surface, and can externally be radiated by heat dissipation channel simultaneously, realize it is quick timely
Thermolysis, on the whole, the radiating of each battery core tends to uniform, and temperature tends to identical, the face of battery pack and air contact
Product is significantly increased, and the air beneficial to flowing removes heat in time, and then has reached the purpose of Homogeneouslly-radiating.
