It is equipped with the stud 76 for installing the second sealing plate 75 at position, is closed when the second sealing plate 75 is mounted at air hole, at this time
Gas in air-guiding aisle is merely able to enter in battery case from wind scooper air outlet 72, without can enter in battery flat.It changes
When transom window is opened, it is installed on the stud 76 of storage position, avoids losing, for use next time.Wherein battery case and lead
The aeration structure of the structures such as fan housing, cabin composition battery case.
Vehicle operation mode of the invention is as follows: when ambient temperature is higher, such as summer, by cabin air-inlet grille
Grate opening is corresponding with the first sealing plate rectangular opening at grid rear portion to be overlapped, and air-flow can pass through, by the second sealing plate 75 on air-guiding aisle
It is fixed at air hole by 75 wing nut of the second sealing plate, air-flow can only pass through the wind scooper of the air-guiding aisle of wind scooper at this time
Air outlet 72 enters the battery case air inlet 81 of battery case, from there through the centrifugal blower on battery case by the cooling wind of passenger compartment
It radiates inside sucking battery case to mould group, again via 3 row of top cover exhaust fan at the top of battery flat after being extracted out by centrifugal blower
To external environment, it is achieved in the outer circulation of battery case ventilation.
When ambient temperature is lower, such as winter seals up the exhaust fan at the top of battery flat using air exhaust passage sealing plate,
The grate opening of cabin air-inlet grille and the first sealing plate rectangular opening at grid rear portion are misplaced, air-flow can not pass through at grid, simultaneously
The second sealing plate on air-guiding aisle is fixed on by air hole by the second sealing plate wing nut, and air-flow can pass through at air hole.When
When centrifugal blower work on battery case, passenger compartment air-flow can not enter battery flat by the grid of air-inlet grille, and battery flat
Internal air-flow can enter air-guiding aisle, then the air-guiding aisle by wind scooper by the air hole on the air-guiding aisle of wind scooper
Wind scooper air outlet 72 enter battery case battery case air inlet 81, by battery case centrifugal blower extract out.Due to battery flat
The top cover exhaust fan 3 at top is sealed up, therefore the gas extracted out from battery case centrifugal blower will not enter external environment, and
It is to enter the air-guiding aisle of wind scooper via the air hole of wind scooper again and then enter battery case, can uses more than battery operation
Heat keeps power battery operating temperature, the air-flow into battery case can also be made to have certain temperature, to prevent battery case
The too low working performance for influencing battery core and battery modules of internal battery core temperature, while not needing to extract the air-flow of passenger compartment, it reduces
Air conditioner load improves vehicle energy-saving effect.Since hot wind enters directly into battery case, the effect to battery case heating is improved
Rate ensure that the temperature of battery case, and battery is made to be in optimal temperature range.
The embodiment 2 of wind scooper of the invention, in this embodiment, the second sealing plate rolling assembling turn on wind scooper bottom plate
Air hole can be turned on or off by dynamic first sealing plate, thus circulation closed mechanism in constituting, other are same as Example 1,
It repeats no more.
Air hole is arranged on the side of wind scooper in this embodiment for the embodiment 3 of wind scooper of the invention, other
It is same as Example 1, it repeats no more.
