Description
Technical field
The utility model belongs to battery system preparing technical field, and in particular to one kind evaporation cooling flame-proof battery system.
Background technology
Because the use of current electric energy is increasingly frequent, and requirement more and more higher of the power device for continuation of the journey, Large Copacity electricity
Pond has obtained universal use.But, such battery radiate accordingly difficulty the problem of also receive watching attentively for people, and grind
Having sent out a variety of has fire-retardant or highly efficient cooling function battery system.
The A of CN 104347840 set corresponding other structures by adding the sponge for being used for absorbing leakage electrolyte,
Obtain a kind of leakage flame retarding construction of Li-ion batteries piles.The A of CN 103682188 add protection by introducing two cavitys
Property gas and flame-resistant insulation liquid, realizing prevents from exploding, avoid short circuit and improving the effect of battery safety.
However, the heat sinking function of above-mentioned battery pack structure is limited, it is difficult to the big and safe battery system of capacity is prepared,
Meanwhile the addition of sponge or protective gas, add corresponding cost and have impact on the useful life of battery.
The A of CN 104466303 are had by the arrangement of setting hydrofluoroether and other details in battery-pack exterior casing
The battery pack of preferable heat sinking function.But, this battery can not but solve the cells bursts caused by factor and quick-fried such as leakage very well
The problem of fried.And the device require battery-pack exterior casing in internal pressure be in -0.09Mpa~-0.01Mpa between be to be in negative pressure shape
State, manufacture and maintenance are all relatively difficult.
Therefore, how to prepare that a kind of structurally simple, economical durable, heat sinking function is good and battery system with anti-flaming function
System, for industry development, it appears particularly important.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of evaporation cooling flame-proof battery system,
Including battery and casing, the casing is connected with cooler by pipeline；Box house is provided with battery and connector；Battery and company
Device is connect to be sequentially connected；The casing is used to load coolant；Relief valve and magnetic valve are set respectively at the top of the left and right of casing；
Casing side set it is total just/always bear interface；In casing inner top, pressure sensor is set.
The connector includes aluminium row or copper bar.
The material of the casing reaches IP67 degree of protection.
The vent pressure of the relief valve is that casing maximum bears the 90% of pressure.
It is described it is total just/always negative interface be waterproof sealing interface.
In the utility model, it (can be fluorocarbons, such as VXF4310, FF31-L that casing, which is used to hold coolant,
Or FL-a), because the viscosity lazy flow of coolant is strong, the capacity of heat transmission is strong, and battery and its heat of collection ear and connector all may be used
To be transmitted to quickly in coolant, coolant is externally given off heat by casing heat radiation and heat transfer, therefore casing can also be set
Count fin or radiating groove increasing heat radiation area enhancing heat-sinking capability.When battery or other parts for immersing coolant generate heat
And when reaching the boiling point of coolant, coolant is changed into gas by liquid and takes away amount of heat, and gas enters cooler through pipeline,
Flowed back to after being condensed in cooler by pipeline in casing, the position of cooler should be higher than casing but not necessarily on just
Side.Because the electrical insulation strength of cooling liquid steam is increased with pressure, therefore casing after steam is produced under normal circumstances
Interior pressure increase can not have to processing, and when pressure sensor detects that pressure is excessive, opens solenoid valve progress pressure discharge operations (are let out
Pressure pressure is tested according to different coolants and surveyed), relief valve, which is arranged to casing, can bear the 90% of maximum pressure when pressure is excessive
And ensure safety during electromagnetism defective valve.
The advantages of the utility model：
1st, battery system of the present utility model in use, when there is overheat in itself in battery, one side coolant
Taking away substantial amounts of heat prevents cells burst, and another aspect coolant prevents burning as extinguishing chemical in itself；When battery has leakage
Coolant, which enters inside battery, during the problems such as damaged makes battery failure, while has radiating and prevent the function of burning；
2nd, the utility model battery system structure is simple, it is not necessary to special maintenance；The equilibrium and radiating of internal system temperature
All it is spontaneous operation, inside does not need the equipment such as fan water pump；More preferable, the structure relative to traditional air-cooled and water-cooling effect
Simpler, security is higher, the battery system especially suitable for high power density.
