Between form air-out passage, the upper cover and air outlet of the ipsilateral one end of air inlet as air-out passage, the upper cover it is another
It is closed by the second wind deflector at end.Size, the quantity of ventilation hole on deflector can be adjusted design as needed, to meet
The result of ventilating heat dissipation of battery pack.The mode that battery modules are mounted on the supporting plate at the top of bottom plate can be selected as needed
It selects, can be in such a way that side be parallel to bottom plate one end, it can also be in such a way that end face be parallel to bottom plate one end.
Further, the battery modules include two end frames, at least one intermediate support and several groups battery pack,
The battery pack includes the single battery that several are serially connected, the several groups battery component layers alignment, described several
The both ends of group battery pack are separately fixed on end frame, and the middle section of the several groups battery pack is fixed at least one
Between on bracket, the two sides of the several groups battery pack are closed by fixed baffle respectively, pass through lid on the outside of the end frame
Plate closing.
Further, the deflector is fixedly mounted on the bottom of battery modules by pull rod.When actual fabrication, generally exist
Pull rod perforation is respectively set in the two sides of deflector one side outwardly, passes through pull rod perforation by pull rod and is fixedly mounted on battery
The bottom that deflector is fixedly mounted on to battery modules is completed in the bottom of the fixed baffle of the two sides of mould group.
Further, blast pipe is set in the air inlet.
To form stronger airflow convection in battery pack, temperature in battery pack is quickly reduced, in entering for the blast pipe
Air supply device is set at air port, and air supply device may generally be centrifugal blower, fan etc..
A kind of air-cooled battery pack of the utility model, structure is simple, offers ventilation by the setting in battery modules bottom
The deflector in hole, what the air intake passage formed by deflector and bottom base plate, upper tops and battery modules top were formed goes out
Wind channel, air-flow flow to the airflow channel formed between battery pack in battery modules through the ventilation hole of deflector from air intake passage,
It is finally flowed out from air-out passage, air flow direction rule, and the ventilation hole of deflector reasonable distribution and can control the size of air-flow, and
When take away the heat that battery pack in battery pack generates and reduce each electricity so that the battery of battery modules is cooling more evenly in battery pack
The temperature difference between pond guarantees the safety that battery pack uses, so that service life of battery pack is longer.
