Detailed description of the invention
Please refer to shown in Fig. 1 and Fig. 2, the improved structure of battery case of the present utility model, it is disposed with many in this casing 1
Individual battery core module 2, is provided with panel beating base plate 3 between the bottom of battery core module 2 and casing 1, in the bottom of panel beating base plate 3 and casing 1
Between be formed with air channel 4；Panel beating base plate 3 is L-shaped, and 3 faces at the bottom of panel beating base plate are provided with multiple rectangular opening 32, described panel beating base plate 3
Sidewall be provided with ventilating opening 33, it is also preferred that the left the height of this ventilating opening 33 is 10mm.The ventilating opening 33 arranging can improve battery core
The radiating efficiency of module 2, can flow uniformly through the air-flow of battery core module 2 so that the heat radiation of each battery core module 2 is uniform simultaneously.
Wherein, panel beating base plate 3 bottom surface is provided with multiple rectangular opening 32, and the bottom of casing 1 one sidewall is provided with air intake vent 11, should
Air intake vent 11 and air channel 4 UNICOM, the top of the relative sidewall with the sidewall setting into air port 11 is provided with and the going out of air channel 4 UNICOM
Air port 12.The air flow being entered by air intake vent 11 flows through air channel 4, and air-flow can be divided into multiple branch, respectively through at the bottom of panel beating
The multiple rectangular openings 32 arranging on plate bottom surface, carry out cooling to battery core module.
It is also preferred that the left the size of rectangular opening 32 is 12 × 209mm, rectangular opening 32 parallel distribution, air outlet on panel beating base plate 3
It is provided with fan at 12, the speed air flow within battery case can be accelerated so that the temperature of the battery core module within Battery case
Spend relatively low.
Wherein, the height in the air channel 4 between the bottom of panel beating base plate 3 and casing 1 is 10-20mm.Panel beating base plate 1 is for propping up
Holding battery core module, the thickness of panel beating base plate 1 is 1mm, stripping and slicing between battery core module 2, panel beating base plate 3 forms multiple 12 ×
The rectangular opening 32 of 209mm so that cold wind stream can pass through these rectangular openings 32.
The length of battery case casing 1 is less than 600m, it is also preferred that the left the height in air channel 4 is 10mm-20mm, it is also preferred that the left air channel is high
Degree is 10mm, 15mm or 20mm.This panel beating base plate 3 is L-shaped, is provided with ventilating opening 33, ventilating opening on the sidewall of panel beating base plate 3
The height of 33 is 10mm, and the length of ventilating opening 33 is less than the width of panel beating base plate 3.The setting of ventilating opening 33, effectively to front row
Battery core module 2 dispel the heat, so that the temperature of front-seat battery core module can preferably reduce so that the temperature of battery core module
Degree uniformly reduces.
Please refer to shown in Fig. 3, when the height in air channel 4 is 10mm, the plumb cut speed cloud atlas of battery core module 2.
Please refer to shown in Fig. 4 and Fig. 5, when air channel 4 height is for 15mm and 20mm, battery core module 2 plumb cut speed cloud keeps
Border arranges constant with other, carries out Flow simulation simulation to its height respectively, the battery core module of observed result gained
2 plumb cut speed cloud distribution maps.
Please refer to shown in Fig. 6, air channel height is 20mm, carries out fluid simulation to the improved structure of battery case 1, can obtain
To battery core module 2 head temperature cloud atlas, it is found that battery core module 2 is obviously divided into two grades from figure.Heel row electricity
Core module 2 temperature is very high, even above serial mode, but fine with battery core module temperature uniformity in row.Front-seat battery core
Module temperature is significantly lower than heel row, and intermediate module temperature is also below both sides module.This is owing to cooling gas is in interposition
Putting the resistance being subject to less, flow speed temperature is high.It is provided with ventilating opening 33 due on the sidewall of panel beating base plate 3, at ventilating opening 33
Under effect, this portion gas is subject to very little resistance in the gap in centre position, so centre position battery core module temperature is lower
Some.
