Into, it is ensured that the uniformity of cooling.
The intake stack includes supervisor and coupled some branch pipes, and the supervisor is connected with fresh air inlet, the branch
Pipe scattering device is in the inlet plenum.It is uniformly dispersed distribution by setting some branch pipes, the cooling wind of entrance can be made more equal
Each battery modules are reached evenly.
The battery modules have several, are divided into two row and are symmetrical arranged, and the supervisor is arranged between two row battery modules,
The branch pipe scattering device is below two row battery modules.It is each that the structure can be such that the cooling wind of entrance more uniformly reaches
Battery modules.
The air outlet of the intake stack is arranged far from battery case width symmetry axis and close to battery case cabinet wall
Position.Battery case bottom half at inwall due to easily accumulating high temperature in edge corner location, intake stack air-out
Mouth is arranged on the temperature that the position is advantageous to cool down the position.
Compared with prior art, the utility model is by setting the fresh air inlet of battery box body to go out air control, intake stack, mould
The air-guiding hole of group casing, in conjunction with import wind deflector and wind deflector is exported, ensure gas pressure intensity, the temperature of each battery modules inlet and outlet
The uniformity of degree, so that it is guaranteed that each battery modules temperature equalization, ensures diverse location battery heat dispersal situations one inside battery modules
Cause property, effectively solves the problems, such as that battery case battery radiates, battery modules internal temperature is balanced and each battery module between temperature equalization, from
And improve the battery bag life-span.
