The position temperature of structure is lower, and when this temperature difference inside battery pack reaches certain value, liquid cooling structure and air contact site hold
It is also easy to produce condensation, the metal pieces into contact such as condensation and shell easily lead to the dangerous generation such as short circuit, seriously affect the safety of battery.
Utility model content
One of the purpose of this utility model is to provide a kind of battery pack, and cooling unit is isolated with the shell of battery pack, is had
After preventing the condensation generated on cooling unit from contacting with shell the perils such as short circuit occur for effect, improve the safety of battery, together
When can also reduce condensation to the issuable corrosion of cabinet.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of battery pack, including shell and the battery modules being provided at its inner portion, cooling unit and elastic cellular unit, institute
It states cooling unit to thermally contact with battery modules, the elastic cellular unit is filled between cooling unit and shell and will be cooling single
Member is isolated with shell, and insulating oil is filled in the elastic cellular unit.When generating condensation because of the temperature difference on cooling unit, elasticity is more
Hole unit absorbs condensation, immiscible between the insulating oil and condensation inside elastic cellular unit, and condensation can not pass through insulating oil
It is contacted with shell, improves the safety of battery.
The elastic cellular unit is at least partly wrapped in cooling unit surface.There are more aqueous vapors inside battery pack
When, elastic cellular unit can open aqueous vapor and cooling unit isolation, effectively avoid aqueous vapor on the lower cooling unit of temperature
Condensation is formed after accumulation, further increases the safety of battery.
The cooling unit includes liquid cooling pipe and/or liquid cooling plate.
The elastic cellular unit is at least partly wrapped in the liquid cooling pipe and/or liquid cooling plate surface.
The cooling unit includes liquid cooling pipe and muti-piece liquid cooling plate, is connected between the muti-piece liquid cooling plate by the liquid cooling pipe
It is logical.
Elastic cellular unit can be wrapped in the liquid cooling pipe surface.
At least one side is contacted with liquid cooling plate in the battery modules.The bottom surface of battery modules and the upper surface of liquid cooling plate connect
Touching is to realize heat exchange.
Housing bottom is equipped with baffle, and the lower surface of liquid cooling plate is fixedly connected after being bonded with baffle, the set-up mode of liquid cooling plate
Air can be completely cut off to the full extent, aqueous vapor is avoided to form condensation after the accumulation of liquid cooling plate surface.
The elastic cellular unit is wrapped in the liquid cooling pipe surface.Due between liquid cooling pipe and shell and battery modules
With gap, liquid cooling pipe is contacted with air by gap and is also easy to produce condensation, and elastic cellular unit is wrapped in liquid cooling pipe surface energy
It is enough that aqueous vapor is effectively avoided to gather to form condensation, and be easily achieved, cost is relatively low.
The elastic cellular unit includes sponge and/or foam.
The insulating oil includes silicone oil.
A kind of battery pack provided by the utility model.Compared with prior art, between cooling unit and shell in filling
Cooling unit is isolated with shell using elastic cellular unit and is effectively absorbed solidifying by elastic cellular unit of the portion filled with insulating oil
Dew, condensation can not pass through insulating oil and contact with shell, improve the safety of battery；Elastic cellular unit wraps up cooling unit,
Aqueous vapor and cooling unit isolation are opened, form condensation after effectively avoiding aqueous vapor from gathering on the lower cooling unit of temperature, elasticity
Porous element is wrapped in the liquid cooling pipe surface, effectively avoids aqueous vapor from accumulating in liquid cooling pipe and forms condensation, and is easily achieved, cost
It is lower.
