The explanation of embodiment is not intended to limit the scope of protection of the present invention.
It as depicted in figs. 1 and 2, is the structural schematic diagram of the air cooling system provided by the present invention for battery pack.It is described
For battery pack air cooling system include a battery pack 10, a heat-exchange device 20 being connect with the battery pack 10, one
A air pump 30 being connected between the battery pack 10 and heat-exchange device 20, and it is connected to the battery pack 10, heat exchange
Gas circuit 40 between device 20 and air pump 30.It is envisioned that the air cooling system for battery pack further includes other
Some functional modules, such as mounting bracket, organize arrangement, electric connection component etc., be those skilled in the art known by
Technology, details are not described herein.
The battery pack 10 should be a kind of prior art in itself comprising the battery pack 11 of multiple groups serial or parallel connection, with
An and sealing shell 12 being coated on the outside of the battery pack 11.It is envisioned that each group of battery pack 11 all includes more
Piece cell piece, these cell pieces can be set according to actual needs with serial or parallel connection together.The cell piece is
Details are not described herein for the prior art.The sealing shell 12 is usually made of insulating material, can be with fire proofing, such as TVP (heat
Plasticity vulcanized rubber) material is made.
The heat-exchange device 20 include a shell 21, at least a piece of refrigerating sheet 22 being arranged in the shell 21,
And at least a piece of filter 23 being arranged in the shell 21.The shell 21 at work, should be a capsul
Body avoids and the extraneous steam for carrying out heat exchange or absorbing the external world.But the shell 211 has the top cover of a sealed set
211.When top cover 211 is opened, the filter 23 can be replaced, because after the excessively water suction of the filter 23,
Water absorbing capacity can be lost, at this moment needs to replace it.It is understood, however, that the shell 21 further includes for fixing
The fixed structure of the refrigerating sheet 22 and filter 23, can select, such as screw, bolt etc., according to actual needs
This is no longer described in detail, and is not also shown in figure.Furthermore it is thinkable that the shell 21 further includes having various sealings
Structure enters in the shell 21 to avoid steam or heat, and causes the disabler of the heat-exchange device 20.The refrigerating sheet
22 can be water-cooled changing plate, and in order to reach abundant refrigeration, the heat-exchange device 20 further includes a chiller 24, institute
Chiller 24 is stated to connect with the refrigerating sheet 22 and for the heat in refrigerating sheet 22 to be transformed into atmosphere.Therefore, described
The outside of the shell 21 is arranged in chiller 24, rather than the inside of the shell 21 is arranged in.The chiller 24
It may include multiple cooling fins, the refrigerant such as water accommodated in the cooling fin.In order to achieve the purpose that circulating cooling agent, the cause
Device for cooling 24 further includes the miniature circulating pump being arranged between the cooling fin and refrigerating sheet 22.The filter 23 plugs
In the shell 21, can the cellular board made of paper material, can sufficiently absorb water.It is understood, however, that
It can also include other some polymer absorbent materials in the cellular board, such as polyacrylate, polyvinyl alcohol, acetic acid
Ethylene copolymer species, polyurethanes, polyethylene oxide class, starch graft copolymerization species, so as to reinforce water absorbing properties.Work as gas
Body enters the shell 21, and the filter 23 can carry out gas to fully absorb steam, to avoid gas shape in cooling
The steam given out in 10 operational process of battery pack at steam and gas.As shown in Fig. 2, in the present embodiment, it is described
