This is higher.
If under existing technical conditions, realizing fire-retardant, the constant temperature requirement of safety battery bag by simple improvement, just
The safety of battery bag is ensured to greatest extent can.
The content of the invention
This utility model purpose is to provide a kind of high reliability enclosed cell bag, while the battery bag also has reduces battery core
The effect of the temperature difference.For achieving the above object, the technical solution adopted in the utility model is as described below.
A kind of high safety constant temperature ternary battery bag, including the seal cover board and housing of close fit each other, sealing
Noble gases are filled with housing, the seal groove of U-shaped is provided with sealing gasket on shell frame, and radiation air is provided with inner walls
Fan, radiator fan are connected with battery module by temperature control modules, and temperature control modules are provided with multiple being distributed in housing
Temperature sensor, be distributed with housing exterior walls section be T-shaped radiating ribs.
According to described high safety constant temperature ternary battery bag, radiator fan is located at the housing side plate of battery module longitudinal direction side
On, each battery module side surface is provided with a temperature sensor.
According to described high safety constant temperature ternary battery bag, radiating ribs are distributed on housing side plate outer wall, the radiating ribs of T-shaped
Two grooves are formed with housing side plate.
According to described high safety constant temperature ternary battery bag, described noble gases are carbon dioxide.
The utility model has the advantages that:
1st, filled with carbon dioxide CO2 in battery bag, pressure carbon dioxide is 0.2-0.25MPa, to prevent under extreme case,
When battery core ruptures, CO2 is fire-retardant, prevents dangerous generation；
2nd, fan is installed in battery bag, for balanced battery core temperature, the control of the battery core temperature difference is made at 1-1.5 DEG C, the battery core temperature difference
Little, battery core concordance is high, and whole group battery bag has extended cycle life.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation after this utility model opens seal cover board（Without radiating ribs）.
In accompanying drawing：1st, sealing bolt；2nd, radiating ribs；3rd, seal cover board；4th, battery module；5th, seal groove；6th, temperature
Control module；7th, radiator fan.
Specific embodiment
Embodiment
1-2 makes to this utility model and further illustrating below in conjunction with the accompanying drawings.
A kind of high safety constant temperature ternary battery bag, the main seal cover board 3 and housing for including close fit each other.Shell
On the frame of body opening, the seal groove 5 of U-shaped is provided with sealing gasket, and noble gases are filled with the housing of sealing.Described inertia
Gas is preferably carbon dioxide.Filled with carbon dioxide CO2 in battery bag, pressure carbon dioxide is 0.2-0.25MPa, to prevent pole
In the case of end, when battery core ruptures, CO2 is fire-retardant, prevents dangerous generation.
The radiating ribs 2 that section is T-shaped are distributed with housing exterior walls.Radiating ribs 2 are distributed on housing side plate outer wall.T-shaped
Radiating ribs 2 form two grooves with housing side plate, increased the area of dissipation of unit housing area, are conducive to the heat of surface of side plate
Amount Quick diffusing is gone out.
Radiator fan 7 is installed in inner walls, radiator fan 7 is connected with battery module 4 by temperature control modules 6.
Temperature control modules 6 are provided with multiple temperature sensors being distributed in housing.Radiator fan 7 is located at 4 longitudinal direction one of battery module
On the housing side plate of side, 7 quantity of radiator fan increases and decreases according to real space layout, and the present embodiment preferentially adopts two.Each electricity
Module 4 side surface in pond is provided with a temperature sensor.The temperature of any one battery module 4 exceedes design temperature, radiation air
Fan 7 will work, and accelerate radiating, reduce the temperature difference, improve battery core concordance, extend whole group battery bag cycle life.
Filled with carbon dioxide CO2, pressure carbon dioxide 0.2-0.25MPa, to prevent under extreme case, battery core in battery bag
During rupture, CO2 is fire-retardant, prevents dangerous generation.Fan is installed in battery bag, for balanced battery core temperature, controls the battery core temperature difference
At 1-1.5 DEG C, the battery core temperature difference is little, and battery core concordance is high, and whole group battery bag has extended cycle life.
Embodiment described above is only that preferred implementation of the present utility model is described, not to this practicality
New design and protection domain are defined, on the premise of without departing from this utility model design concept, common in this area
Various modifications and improvement that engineers and technicians are made to the technical solution of the utility model, all should fall into guarantor of the present utility model
Shield scope.
