Description
Technical field
The utility model relates to a kind of heat-dissipating casing, specifically a kind of spiral A shape fin heat-dissipating casing for cylinder type lithium battery monomer.
Background technology
Current cylinder type lithium battery Large Copacity is generally 100-400Ah, and shell mostly is the materials such as aluminium, aluminium alloy, polypropylene, is that entity is hermetic, can not be taken away by heat timely and effectively in air cooled process.
Electrokinetic cell core produce heat mainly by electric reaction heat, polarization heat, ohmic internal resistance is warm, electrolyte decomposition is hot and SEI film decomposition heat.A large amount of heats can be produced when hot environment especially high-power discharge and recharge, if these heats can not lose in time by cause internal battery pack temperature constantly to raise and temperature distributing disproportionation even, thus reduce the serviceability of battery, cycle life and fail safe.
Utility model content
The purpose of this utility model is to provide a kind of spiral A shape fin heat-dissipating casing for cylinder type lithium battery monomer, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of spiral A shape fin heat-dissipating casing for cylinder type lithium battery monomer, comprise outer cover body, outer cover body is coated on the outer surface of cylinder type lithium battery monomer, the outer surface cold extrusion of described outer cover body is one-body molded spiral A shape fin, the cross section of spiral A shape fin is triangle, the material of outer cover body is aluminium, the thin polypropylene plastics shell that outer setting one deck of described spiral A shape fin is identical with spiral A shape fin structure.
As further program of the utility model: the Zinc coat of described outer cover body.
As further program of the utility model: the spacing 3mm between described spiral A shape fin, the gap of the bottom slot of spiral A shape fin is 1mm.
As further program of the utility model: the wing of described spiral A shape fin is wide is 1.5mm, wing height is 2mm.
As further program of the utility model: the thickness of described thin polypropylene plastics shell is 1mm.
As further program of the utility model: the end face diameter of described cylinder type lithium battery monomer is 75mm, height is 380mm.
Compared with prior art, the beneficial effects of the utility model are: for spiral A shape is finned on the outer cover body of this practicality, relatively traditional drum type brake shell has compact conformation, quality is light, and unit heat exchange area is large, the heat that can effectively scatter and disappear in discharge and recharge and use procedure.
Accompanying drawing explanation
