Abstract
The invention discloses a kind of power batteries to be quickly cooled down system, is mainly technically characterized by：It takes different cooling schemes automatically according to different environment temperatures, including increases airflow speed with force(d) (draft) fan, reduce gas flow temperature with semiconductor cooler, realize the cooling to power battery in a fast and efficient manner.
Description
Technical field
The present invention relates to a kind of fast cooling system, particularly relates to a kind of power battery and be quickly cooled down system.
Background technology
With popularizing for electric vehicle, quick charge is extremely urgent for battery, but high temperature caused by quick charge,
It is very easy to cause battery deflagration accident, if especially charged in the case of summer automobile outdoors direct sunlight, itself
Vehicle interior temperature is as high as six or seven ten degree, the heat generated along with battery charging so that more prominent the case where battery detonation.And
It is exactly effect unobvious that existing battery cooling system, which is not complicated, so that cannot be promoted in practical applications.
Invention content
It is an object of the invention to overcome high temperature to have an impact quickly charging battery and provide one kind it is simple in structure, at
This is low, and can play the cooling system of fast cooling.
The present invention is achieved by the following technical solution：A kind of power battery is quickly cooled down system, including supercharging wind
Fan, semiconductor cooler, beam, air cavity, controller, temperature sensor；Before the force(d) (draft) fan is set to air cavity, with air cavity
It is connected by tracheae, the high pressure gas in air cavity passes through air cavity, beam, semiconductor cooler cold end by venthole（Hot junction）
Battery pack is quickly sprayed to afterwards, and high-temperature gas in battery pack is driven to be discharged rapidly；The semiconductor cooler be force(d) (draft) fan not
It is enough fast cooling, temperature starts when being more than some warning point, and after startup under the push of high pressure gas, cold air is rapid
Flowing discharge, makes battery temperature quickly reduce；In certain cold districts, when battery temperature is too low, force(d) (draft) fan is not transported
Row, semiconductor cooler switching electric current direction make one end in battery pack heat, to achieve the purpose that heat up to battery；Battery
Temperature sensor is set in group, and the temperature that temperature sensor detects is transmitted to controller, supercharging wind is controlled by controller in real time
The switch of fan and semiconductor cooler.
The force(d) (draft) fan, semiconductor cooler give battery pack fast cooling in a joint manner by chip controls.
System can reverse as warming-up device the semiconductor cooler at low temperatures.
The air-flow transit route uses the basic structure as shown in Figure of description.
The configuration of the present invention is simple, it is at low cost.When temperature is more than some warning point, control chip starts supercharging wind
Fan, high pressure gas accelerate the circulation of air so that the temperature of internal battery pack reduces；When high-speed gas is not enough to balancing battery
The heat that group generates so that the temperature of internal battery pack continues to increase, then controls chip and start semiconductor cooler, semiconductor system
Cooler makes one end in battery pack freeze by pyroelectric effect, and cold air quickly passes through battery pack row under the push of high pressure gas
Go out, battery pack temperature is made quickly to reduce.
Description of the drawings
Figure of description 1 is the structural schematic diagram of the present invention
Specific implementation mode
As shown in the picture, before force(d) (draft) fan is set to air cavity, it is connected by tracheae with air cavity, when temperature is guarded against more than some
When point, control chip starts force(d) (draft) fan, and the high pressure gas in air cavity passes through air cavity by venthole, beam, partly leads
Chiller cold end（Hot junction）Battery pack is quickly sprayed to afterwards, and high-temperature gas in battery pack is driven to be discharged rapidly；Force(d) (draft) fan not
It is enough fast cooling, when temperature is more than another warning point, control chip starts semiconductor cooler, makes one in battery pack
End refrigeration, under the push of high pressure gas, cold air flows rapidly discharge, and battery temperature is made quickly to reduce；On certain cold ground
Area, when battery temperature is too low, force(d) (draft) fan is not run, and semiconductor cooler switching electric current direction makes in battery pack
One end heats, because bottom venthole is small, thermal loss very little, the air after heating rises by the way that convection current is past, to reach to electricity
The purpose of pond heating；Temperature sensor is set in battery pack, and the temperature that temperature sensor detects is transmitted to controller in real time, by controlling
Device processed controls the switch of force(d) (draft) fan and semiconductor cooler.
