Just, but wind flow is relied on to radiate, low efficiency, effect is limited, and hand environment temperature is affected.Liquid cooling is cold with liquid
Matchmaker flows through battery surface by pipeline and takes away heat, and radiating efficiency is high, and effect is obvious, but its structure is complicated, cost compared with
Height, while liquid cooling needs compressor, pipeline etc. to increase mould group weight, reduces the energy density per unit volume of battery.Direct-cooled is to make
Cryogen is refrigerant, using the principle of evaporation latent heat, is directly taken away mould group heat, efficiency is best, and rhythm is compact, but its skill
Art difficulty is big, at high cost, and practical application technology is also immature.
In view of this, it is necessory to provide a kind of battery pack radiator structure to solve problems of the prior art.
Utility model content

Heat is comprehensively taken out of.
Preferably, the cooling fin with a thickness of 0.01 ~ 0.3mm.More preferably, cooling fin with a thickness of 0.1 ~
0.2mm.The thickness of cooling fin is too small not to have preferable heat spreading function, and the thickness of cooling fin is excessive will lead to battery core volume energy
Metric density reduces.
Preferably, the cooling fin is the high thermal conductivity graphite heat radiation fin that interlayer thermal conductivity is greater than or equal to 800W/mK.It is preferred that
For PI(polyimides) graphite heat radiation fin.The thermal conductivity of cooling fin is higher, the effect that the heat generated when battery core is worked is taken out of
Rate is higher.
Preferably, the radiator is made of the wavy laminate of multilayer, and wavy laminate described in multilayer is arranged in a staggered manner and shape
At porous channel.Porous channel accelerates heat dissipation for air-cooled circulation.
Preferably, the air inlet and the air outlet are provided with fan.The fan of air inlet is for cold wind to be sent into
Shell, the fan of air outlet are used to take hot wind out of shell.
The utility model has the beneficial effects that: the utility model provides a kind of battery pack radiator structure, if including shell,
