Description
Technical field
This utility model relates to battery technical field of heat dissipation, a kind of 18650 cold bags of circular batteries liquid.
Background technology
In recent years, owing to the problem of energy cost and environmental pollution is more and more prominent, pure electric automobile and mixing are dynamic
Power automobile can significantly eliminate the advantage of even zero-emission vehicle tail gas with it, is paid attention to by government and each Automobile Enterprises.
One of key technology of new-energy automobile is electrokinetic cell, and on the one hand the quality of battery decides the cost of electric automobile, another
Aspect decides the distance travelled of electric automobile.But pure electronic and hybrid vehicle still to have a lot of technical problem to need prominent
Broken, battery and capacity attenuation are major issues, and the temperature of the service life of battery and capacity attenuation and battery system
Degree difference and temperature elevation amplitude have great relation.
Battery produces substantial amounts of heat at work, if this heat can not be discharged in time, it will make the temperature of battery bag
Degree constantly rises, and in battery bag, the temperature contrast of the battery of diverse location can gradually expand, and makes battery be in high temperature rise, the big temperature difference
Adverse circumstances in, thus affect the service life of electrokinetic cell.Particularly in hot summer, due to ambient temperature very
Height, final temperature rise much larger than the rational working range of battery, thus will have a strong impact on battery life and capacity, and put for battery
Electrical property causes bigger puzzlement.Still further aspect, battery service behaviour at low temperatures is very poor, particularly in cold winter
Particularly evident, charge-discharge performance is far short of what is expected compared with under room temperature, in order to make battery the most also can meet electrokinetic cell discharge and recharge
Demand, battery bag carries out heat temperature raising making it be operated in optimal discharge and recharge temperature is necessary heat management measure.
Therefore, in order to improve the performance of new-energy automobile, make battery system play optimal performance and life-span, it is necessary to right
Battery provides high temperature heat radiation, the heat management device of low-temperature heat.

Two openings 4 are respectively as inlet and liquid outlet.
Wherein, described liquid cold runner 3 is arranged at the inside of described heat sink 1.Must be to pass through feed liquor with outside contacting
Mouth and liquid outlet, it is ensured that the sealing of the liquid cold runner 3 between inlet and liquid outlet.
Wherein, described battery settling hole 2 is the through hole running through described heat sink 1.The depth ratio circular batteries of this through hole
Height is short.
Preferably, the surface of heat sink 1 is coated with insulating moulding coating layer；Or it is provided with in heat sink 1 and pacifies around battery
Dress hole 2 is provided with vacuum cavity, is provided with the connectivity port connected with this vacuum cavity on heat sink 1, is used for and the external world
Evacuator connects, and plug seal is passed through in this connectivity port.
Preferably, the inwall of described battery settling hole 2 and the inwall of liquid cold runner 3 are coated with heat-conductive coating layer.
Above embodiment simply indicates that rather than limits this utility model, therefore all according to this utility model patent application
The equivalence that method described in scope is done changes or modifies, and is all included in this utility model patent claim.
