Description
Technical field
Electric automobile or hybrid power automobile battery system security fields are the utility model is related to, particularly relate to a kind of module
Smoke evacuation heat insulation structural.
Background technology
With the growth of electric automobile and hybrid vehicle quantity, the safety of battery system is also increasingly taken seriously,
Caused spontaneous combustion is even exploded after specifically how preventing battery thermal runaway, turns into the emphasis of industry research.
In current power driven system, generally relief valve (or air bleeding valve), above battery core, battery pack are carried in battery core
Interior to be provided with cover plate, cover plate forms discharge flue with battery core, and when battery core thermal runaway, high temperature and high pressure flue gas is gushed out from relief valve, leads to
Discharge flue is crossed to emit；But by space is limited, discharge flue is often narrow, a large amount of flue gases are in discharge process, meeting
Contacted with other battery cores not out of control, cause other battery core temperature to raise, it is easy to cause chain thermal runaway.
Therefore, how a kind of smoke evacuation heat insulation structural is provided, both flue gas can smoothly be discharged, while flue gas and its can also be completely cut off
The direct contact of its battery core not out of control, turn into a difficult problem of the pendulum in face of those skilled in the art.
