Background technology
As global energy crisis and environmental problem increasingly sharpen, orthodox car industry is faced with unprecedented sternness
Challenge.Pure electric automobile as a kind of new energy-saving and environment-friendly automobile have low energy consumption, it is simple in construction, vibration and noise it is low,
The advantages that non-pollutant discharge, turn into the important directions of future automobile development.Lithium-ion-power cell is with its operating voltage height, ratio
The advantages that energy and specific power are big, self-discharge rate is low, service life cycle is long, memory-less effect, non-environmental-pollution, turns into electronic
The first choice of automobile power cell.Power battery pack produces substantial amounts of heat in car running process, if heat does not shed in time
Battery pack temperature will be caused to rise.Too high temperature not only reduces the service efficiency and cycle life of lithium battery, it is also possible to leads
Pond eventual failure is sent a telegraph, or even the danger of explosive fire accident occurs.Therefore, temperature during battery set charge/discharge must be controlled
System.
No matter the radiating aluminium sheet of traditional soft-package battery is radiated using unilateral, bilateral or three sides, no matter using air or
Liquid cooling medium, the bang path of heat is all first to be delivered to heat-dissipating aluminium plate from battery core, then along perpendicular to aluminium plate thickness
Direction is delivered to heat-dissipating aluminium plate surrounding, and heat is taken away finally by air or cooled plate.Have a disadvantage in that：1st, heat abstractor
Volume is big, takes big quantity space；2nd, radiating efficiency is relatively low.
Utility model content
For in the prior art the defects of, the purpose of this utility model is to provide a kind of is changed based on the convection current of soft-package battery surface
The novel radiating device of heat.
According to the novel radiating device provided by the utility model based on soft-package battery surface heat convection, including to circulation
Road, air inlet cover plate and exhaust cover plate, the air inlet cover plate are connected to the side of the convection channel, the exhaust cover plate connection
In the opposite side of the convection channel, the convection channel is spaced by some fin and formed, two-by-two between fin
Clearance space forms gas flow, and the battery cell of soft-package battery is close to be arranged on the fin respectively.
Preferably, the air inlet cover plate includes air inlet, is provided with the air inlet into filter element.
Preferably, the exhaust cover plate includes exhaust outlet, and centrifugal fan is provided with the exhaust outlet.
Preferably, each two battery cell is correspondingly close to two surfaces for being arranged on a fin.
Preferably, the convection channel also includes connection framework, to the fin that is connected, the air inlet cover plate
And the exhaust cover plate.
Compared with prior art, the utility model has following beneficial effect：
1st, it is centrifugal fan, convection channel and battery monomer bracket is integrated, it is compact-sized, save space；
2nd, the big advantage of soft-package battery surface area is made full use of, using surface heat loss through convection, is dissipated than one side, bilateral, three sides
The area of heat greatly increases, and radiating effect significantly improves；
3rd, the number of heat sink can be adjusted according to the annexation between the module size of soft-package battery, capacity and module,
Engineer applied it is versatile.

Embodiment
The utility model is described in detail with reference to specific embodiment.Following examples will be helpful to this area
Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that to ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, some changes and improvements can also be made.
These belong to the scope of protection of the utility model.
As depicted in figs. 1 and 2, the novel radiating device provided by the utility model based on soft-package battery surface heat convection
Mainly include 3 three convection channel 1, air inlet cover plate 2 and exhaust cover plate part compositions, air inlet cover plate 2 is connected to convection channel 1
Side to air inlet, exhaust cover plate 3 is connected to the opposite side of convection channel 1 to be vented.
As shown in Fig. 2 having an air inlet 201 on air inlet cover plate 2, set on air inlet 201 into filter element 202,
The gas for entering convection channel 1 is filtered, removes dust therein, so as to ensure working environment of the battery operation in cleaning
Under；It is vented on cover plate 3 and exhaust outlet 301 is set to be exhausted by exhaust apparatus, in the present embodiment, in exhaust outlet 301
On be connected with centrifugal fan 5 and be exhausted, but the utility model is without limitation.Preferably, centrifugal fan 5 is sealed connection
On exhaust outlet 301, the gas in convection channel 1 is extracted out with powerful wind-force.
Formed as shown in figure 3, convection channel 1 is spaced by some fin 101, two-by-two between fin 101 between
Gas flow is formed every space, the both ends of all fin 101 are fixed by connection framework 102, air inlet cover plate 2 and exhaust
Cover plate 3 is equally fixed in connection framework 102.Soft-package battery module is made up of multiple battery cells, by each two battery list
Body is correspondingly close to be arranged on two surfaces of a fin 101, in this way, by taking 24 battery cells as an example, it is necessary to 12
The convection channel 1 that fin 101 forms.
In the operating condition, extraneous gas is entered from the air inlet 201 of air inlet cover plate 2 by the driving of centrifugal fan 5,
By entering after entering the filtering of filter element 202 in gas flow, heat loss through convection is formed with battery surface, the heat of battery is by dissipating
Backing 101 and the gas entered absorb and discharged from the exhaust outlet 301 of exhaust cover plate 3.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
