In order that the purpose of the present invention, technical scheme and advantageous effects become apparent from understanding, below in conjunction with accompanying drawing and
Embodiment, the present invention will be described in further detail.It should be appreciated that the specific implementation described in this specification
Mode is not intended to limit the present invention just for the sake of explaining the present invention.
Also referring to Fig. 1 and Fig. 2, the present invention provides a kind of electrokinetic cell and packs cooling system 100, including sound collecting dress
Put 10, thermoacoustic refrigeration device 20, BMS devices 30 and battery bag 40；The thermoacoustic refrigeration device 20 includes temperature end 21, low-temperature end
22 and the return channel 23 between the temperature end 21 and low-temperature end 22；The sound collection means 10 are arranged at the thermoacoustic
The side of the close temperature end 21 of refrigerating plant 20, the sound collection means 10 collect the acoustic energy around battery bag 40,
And acoustic energy dress is changed to heat energy, the heat energy is sent to the temperature end 21, between the temperature end 21 and low-temperature end 22
Temperature difference is produced, the low-temperature end 22 connects battery bag 40, and the low-temperature end 22 absorbs the heat of battery bag 40；The BMS dresses
Put the temperature of 30 detection battery bags 40 and control being turned on and off for the sound collection means 10.Specifically, the BMS devices
That is battery management system (Battery Management System).
The sound collection means 10 are also associated with sound source sound-producing device 50, and the sound source sound-producing device 50 produces sound energy
Measure and be sent to the sound collection means 10.Specifically, when battery bag refrigeration system 100 provided by the invention is applied to electronic
During automobile, the acoustic energy around battery bag that the sound collection means 10 are collected include electric automobile self-operating acoustic energy and
The acoustic energy of surrounding environment, reduces noise pollution during electric automobile during traveling；During acoustic energy deficiency around battery bag, start sound source
Sound-producing device 50, sound source sound-producing device 50 produce acoustic energy and are sent to the sound collection means 10, further increase sound
Acoustic energy in collection device 10, sound source sound-producing device 50 can be the high piezoelectric speaker of small volume, frequency.
The thermoacoustic refrigeration device 20 also includes shell 24, and the shell 24 has a resonant cavity 241, the temperature end 21,
Low-temperature end 22 and return channel 23 are contained in the resonant cavity 241.Specifically, the sound collection means 10 be arranged at it is described common
Shake one end of chamber 24, and the heat energy that sound collection means 10 are converted is sent to the temperature end 21.
Be filled with fluid media (medium) in the resonant cavity 241, the fluid media (medium) is compressible and has a larger coefficient of expansion
Working medium, in present embodiment, the fluid media (medium) is nitrogen or helium, environmentally friendly.
The BMS devices 30 detect the temperature of battery bag 40 and control being turned on and off for the sound collection means 10.
First, BMS devices 30 judge whether the temperature of battery bag 40 is more than default maximum temperature, if being more than, BMS devices conveying life
Order controls the sound collection means 10 to open；Then, thermoacoustic refrigeration device 20 is worked, and battery is cooled down by the low-temperature end 22
Bag 40；Secondly, BMS devices 30 judge whether the temperature of battery bag 40 is less than default minimum temperature, if being less than, BMS devices
Movement order controls the sound collection means 10 to close；Finally, thermoacoustic refrigeration device 20 is stopped.
The operation principle of the thermoacoustic refrigeration device 20 is based on thermoacoustic effect, when heat energy is applied to the temperature end 21
When, the fluid media (medium) around the temperature end 21 is heated, and fluid media (medium) expands and is pushed into the folded gap of the plate of return channel 23
In, because the temperature of return channel 23 is relatively low, volume contraction after fluid media (medium) heat exchange, meanwhile, pressure caused by fluid media (medium) expansion
Fluctuation is sent to the low-temperature end 22 and reflected, and the pressure oscillation of reflection is superimposed with the contractile motion of fluid media (medium), in a certain frequency
