Description
Technical field
The present invention relates to a kind of lithium ion battery bag or battery modules, suitable for the lithium ion battery bag or battery modules
Coolant and cooling means.
Background technology
In recent years, with Devoting Major Efforts To Developing of the China to environment-friendly type new energy, lithium battery becomes energy storage, UPS, electric automobile
Main power source, wherein Development of Electric Vehicles is the quickest, but also brings some problems, such as the heat pipe of battery bag simultaneously
There is larger differentiation in terms of reason.Existing battery bag is mainly using natural cooling, the air-cooled, radiating mould that duct type liquid is cold
Formula, such heat management mode can alleviate the heat dissipation problem of battery bag to a certain extent, but can not be fundamentally thorough
The problem of battery bag is generated heat and heated under all kinds of operating modes, under all kinds of environment is solved, on the one hand heat management mode so can not
The heat allowed in battery bag is transmitted to beyond battery bag rapidly, and the heat inside another aspect can be superimposed, so as to cause battery bag
Interior temperature more and more higher, finally directly affects the service life of battery bag and the security performance of battery bag.Electric automobile is used
Bad environments, frequency of use are high, and the electrokinetic cell requirement for carrying is more strict, harsh, and it must assure that in battery bag
Thermal field it is uniform, the requirement due to battery bag to peripheral degree of protection, anti-seismic performance is very high, so existing technical deficiency is with enough
Reach that it is required.Therefore solve the problem of battery bag is hot into Liao Ge manufacturers it is in the urgent need to address the problem of.Existing heat pipe
Still there is very big defect in reason pattern；Natural air cooled (it is most of by battery bag and heat exchange with outside, or pass through battery bag
Inside installation mini-fan is air-cooled to battery core progress, plays heat exchange action).The heat generation characteristic of battery core itself is all relied on,
Battery bag temperature is too high under extreme condition, and the infringement to battery core is huge, and its security less can guarantee that battery bag is for a long time higher
Temperature environment under work, the life-span of battery bag can drastically decline.
Traditional air-cooled pattern, because needing to produce thermal convection current inside and outside battery bag, whole battery bag is difficult to accomplish sealing, this
The problem of kind of scheme is brought be, inner air and outer air convection current can bring many dust, impurity and vapor into, thus to battery bag inside
High and low pressure connection parts, electronic unit, high tension apparatus, battery core bring the risk of accelerated ageing, electronic component, high-voltage device
The risk of part failure, the equally security performance to battery bag brings huge threat.New ducted cooling pattern is (in battery
Cooling pipe is wound between module battery core, carrying out an indirect heat exchange by the liquid in cooling pipe cools down).Because electric
Heat inside the bag of pond is needed by the cooling liquid in pipeline heat outflow come so being needed between the battery core gap of battery bag
Very many pipelines are laid out, for cylindrical electrical core, structure, layout, the technique of pipeline are all very complicated, and
To manufacturing cost huge pressure is brought with production efficiency.Pipeline inside single battery bag is more, and interface will be more, and many one
Individual interface will increase the risk of a leakage, and cylindrical electrical core is fairly limited with the area of tube contacts in addition, is normally whole
The 1/4 of battery core, heat-conducting area is limited, and single module is bigger, and temperature range will be wider, and the input side of cooling liquid is with coolant
Body outlet side, due to the path factor of cooling liquid, temperature range can be relatively wide.Whole battery bag is in the larger ring of this temperature difference
Worked in border, equally the performance to battery bag has very havoc.Either natural cooling, air-cooled or ducted cooling are belonged to
Cooling indirectly, its cooling effect and efficiency are all restricted.If by the way of directly cooling down, being needed to improve cooling effectiveness
Consider battery case directly contacted with cooling medium after effect, if cooling medium selection it is improper, corrosion cell can be produced
Shell, both positive and negative polarity by medium connection cause short circuit, medium in cold cycling unstable chemcial property, medium is inflammable and increases
Potential safety hazard of battery work etc..The existing coolant applied to the indirect type of cooling is selectively less, and condition of work will
Ask stricter.In the indirect type of cooling, a large amount of at present use is water/ethylene glycol mixed solution, silicone oil or silicone grease.Wherein, water/
Although the mixing liquid mobility of ethylene glycol is preferably, easily aoxidized being an exposure in oxygen, perishable battery case after oxidation.
Silicone oil, silicone grease chemical composition it is although more stable, but mobility is poor and has certain electric conductivity.Therefore, use with
Upper a few money coolants are very high to the cooling pipe sealing requirements of battery bag, if once occurring leakage, there is very big potential safety hazard.
