In, it is preferable that the sealing of blast pipe 3 is fixed in the air inlet 21, and the sealing of discharge pipe 4 is fixed on the air outlet
In, so that the wind in blast pipe and discharge pipe be avoided to leak, influence heat dissipation effect；
Specifically, the radiator further includes two fans 6, and the fan 6 is fixed by screws in the air inlet
21 and the air outlet in, the blast pipe 3 and the discharge pipe 4 are sheathed on outside the fan；It can be improved by fan
The flow velocity of the air-conditioner wind (or natural wind) flowed in and out improves the cooling efficiency of soft-package battery packet and heat dissipation effect in the unit time
Fruit；
As shown in figure 3, the radiator further include be arranged in the upper surface of the soft-package battery packet 5 the first metal dissipate
Thermosphere 7 and the second metallic radiating layer of the lower surface that the soft-package battery packet is arranged in (are not shown in the figure, structure and the first metal
Heat dissipating layer 7 is essentially identical), the heat of internal battery core can be quickly transmitted to first heat dissipation metal by the soft-package battery packet
The inner surface of layer and second metallic radiating layer, and then pass through first metallic radiating layer and second metallic radiating layer
It is transmitted to outer surface by metal itself, thus more efficient and rapidly realize leading for soft-package battery packet internal heat
Out, specifically, first metallic radiating layer and second metallic radiating layer can be used copper or aluminium etc. and readily conduct heat metal；At this
In the specific implementation process of utility model, the following table of the upper surface of first metallic radiating layer and second metallic radiating layer
Face, which can be equipped with multiple zigzag air ducts, by using laciniation can increase heat dissipation area, it is easier to realize it is thermally conductive and
Heat dissipation；
Also, the zigzag air duct of the upper surface of first metallic radiating layer can be with 2 structure of battery pack external air hood
At heat dissipation wind channel, the zigzag air duct of the lower surface of second metallic radiating layer can cover 1 and constitute with the battery pack bottom to be dissipated
Hot-flow flue, in this way, can be by the heat dissipation wind channel according to certain from the air-conditioner wind (or natural wind) that the blast pipe 3 enters
Path flow into the discharge pipe 4, to high speed and effectively take away the heat that soft-package battery packet transmits from inside to outside, guarantee soft
The two-sided large area heat dissipation on packet battery pack two surfaces up and down, radiating efficiency is high and uniform temperature is good, the temperature difference is small.
And in order to which the soft-package battery packet is mounted on accurate placement location, it can be arranged on the battery pack bottom is covered
Locating part, to limit to the soft-package battery packet, the selection and setting of specific locating part already belong to the prior art,
