Battery produces substantial amounts of heat at work, if this heat can not be discharged in time, the temperature that will make battery bag constantly rises, in battery bag, the temperature contrast of the battery of diverse location can gradually expand, make battery be in the adverse circumstances of high temperature rise, the big temperature difference, thus affect the service life of electrokinetic cell.Particularly in hot summer, owing to ambient temperature is the highest, final temperature rise much larger than the rational working range of battery, thus will have a strong impact on battery life and capacity, and cause bigger puzzlement for cell discharge performance.Still further aspect, battery service behaviour at low temperatures is very poor, particularly particularly evident in cold winter, 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 the demand of electrokinetic cell discharge and recharge, 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 battery provides high temperature heat radiation, the heat management device of low-temperature heat.
The heat management of existing battery typically uses Natural Heat Convection, air blast cooling heat radiation, vaporizer to provide the modes such as low-temperature receiver heat radiation, liquid-cooling heat radiation.Wherein liquid-cooling heat radiation mode is owing to the specific heat capacity of liquid is much larger than the specific heat capacity of air, less flow just can take away bigger heat, thus take the heat of battery system to its exterior efficiently, reduce the temperature rise of battery system, improve the serviceability of battery.The most a lot of new-energy automobiles all use liquid-cooling heat radiation mode to carry out thermal management scheme as battery system.But the existing cold and hot Managed Solution of liquid is mainly clipped between two battery modules by liquid cooling plate block, or the interspersed cold pipeline of liquid between battery, the heat that battery is sent can not be directly passed to the cold liquid of liquid, or owing to the cold pipe of liquid only contacts with the very fraction outer surface of battery, make the thermal resistance at the cold liquid of thermal source i.e. battery to liquid bigger, so that temperature rise increases, it is impossible to play the function of liquid cooling system completely.
Summary of the invention
It is an object of the invention to provide the honeycomb fashion liquid cooling apparatus of a kind of lithium battery, solve lithium battery to the excessive problem of the thermal resistance of the cold liquid of liquid, the heat produced when making battery operated can rapidly and efficiently be delivered to the cold liquid of liquid, then be recycled to liquid cold heat exchanger by liquid at the cold pipeline of liquid and taken in its exterior environment by heat.

Further, the length of described battery cavities is not more than the height of battery.More optimizedly the length of battery cavities namely the width of heat collector cavity are just equal with the height of lithium battery, it is thus possible to preferably dispel the heat battery.
Further, the inwall of described battery cavities is provided with one layer of heat-conducting layer, and the material of described heat-conducting layer is thermal interfacial material.
Further, described thermal interfacial material is heat-conducting silicone grease.
Further, described liquid cooling system includes the cold pump of reserving liquid tank, liquid, radiator, and the port of export of described reserving liquid tank is connected with the inlet of heat collector cavity by the cold pump of liquid, and the liquid outlet of described heat collector cavity is connected formation circulation fluid cold loop by radiator with reserving liquid tank.
Wherein radiator is preferably air cooling heat exchanger.

During use, being placed in battery cavities by lithium battery monomer, the outer wall of battery fits with the inwall of battery cavities, then increases by one layer of heat-conducting layer formed by thermal interfacial materials such as heat-conducting silicone greases between which.Due to liquid outer wall flowing round battery cavities in liquid chambers, the heat that battery produces can be taken away fully, reach more preferably heat sinking function.
Refrigerant liquid in reserving liquid tank imports the liquid chambers in heat collector cavity by the cold pump of liquid from inlet, pass through in passage between battery cavities outer wall two-by-two, in time area battery is because sending out heat thermogenetic, then goes out to enter radiator to carry out heat exchange from liquid outlet liquid, it is achieved the purpose of circulation temperature lowering.
Thermal interfacial material (Thermal Interface
Materials) be also called heat-conducting interface material or interface Heat Conduction Material, be mainly used in filling up microvoid and the hole of surface irregularity that bi-material engages or produces during contact, reduce heat transfer impedance, improve thermal diffusivity.There is imperceptible rough space between the surface of solids and the surface of solids, if they be directly mounted together, the real contact area between them typically only has the 10% of foot of radiator area, and remaining is the air gap.Because air conduction coefficient only has 0.026W/ (m K), it is the non-conductor of heat, battery is bigger with the thermal contact resistance of battery room wall, the conduction of heat can be hindered, the usefulness ultimately causing heat management reduces.Use the thermal interfacial material with high-termal conductivity to fill these gaps full, get rid of air therein, between battery and battery room wall, set up effective thermal conduction path, can the lowest thermal contact resistance, make the effect of radiator be played fully.
