The utility model provides a brake drum thermal power generation self-loopa cooling system realizes refrigerated method, include:
when a driver steps on the brake pedal 1, the friction between the brake pad 11 and the inner surface of the brake drum 10 is increased, and the temperature does not reach the set temperature of the temperature sensor by 180 ℃, the charging and discharging management module 17 is in a charging state; when the heated temperature of the surface of the integrated thermoelectric generation piece 9, which is in contact with the brake drum 10, rises, the electronic activity of the surface of the integrated thermoelectric generation piece 9, which is in contact with the brake drum, of the N-type semiconductor 93 is increased, and the diffusion to the copper conductor 92 at the radiator end is started, and under the open-circuit condition, a space electric field is formed at two ends of the N-type semiconductor of the integrated thermoelectric generation piece 9; when the charging and discharging management module 17 and the integrated thermoelectric generation sheet 9 form a closed circuit, the closed circuit generates current under the driving of the thermoelectric electromotive force; the current is rectified by a rectifier bridge and then regulated by a charge and discharge management module 17, and the output regulated current is used for charging an electric power storage system 18;
when the temperature of the brake pad 11 and the inner surface of the brake drum 10 reaches 180 degrees of the set temperature of the temperature sensor, the charge-discharge management module 17 is in a discharge state, electrons enter the P-type semiconductor of the integrated thermoelectric generation piece 9 from the copper conductor 93 at the radiator end under the action of electromotive force of the power storage system 18, the electrons fill positive charges in holes of the P-type semiconductor of the integrated thermoelectric generation piece 9, the energy is reduced, and heat is released outwards; when electrons enter the copper conductor 92 at the end of the radiator from the P-type semiconductor of the integrated thermoelectric generation sheet 9 under the action of electromotive force of the power storage system, the electrons need to raise energy, and the electrons absorb heat from the outside; the brake drum 10 heat is absorbed; the brake drum 10 is cooled to provide cooling.
In the present embodiment, an electromotive force due to a temperature gradient, i.e., a thermoelectromotive force, occurs at both ends of the semiconductor according to when the diffusion drift effect and the effect of the space electric field cancel each other, i.e., a steady state is achieved. The direction of the thermoelectric electromotive force of the N-type semiconductor is that the high-temperature end of the brake drum points to the low-temperature end of the radiator (Seebeck coefficient S) AB Negative).
When the diffusion drift effect and the effect of the space electric field are mutually counteracted, that is, a stable state is reached, an electromotive force, namely a temperature difference electromotive force, caused by a temperature gradient appears at two ends of the semiconductor. The direction of the thermoelectromotive force of the P-type semiconductor is that the low-temperature end of the radiator points to the high-temperature end of the brake drum (Seebeck coefficient S) AB Positive).
Then according to the following formula:
ΔV＝S AB (T 2 -T 1 )＝S AB ΔT
Δ V-thermoelectromotive force (sum of all N-type and P-type semiconductor thermoelectromotive forces)
SAB-temperature Seebeck coefficient (N type semiconductor is negative, P type semiconductor is positive)
T2-temperature difference power generation sheet brake drum end temperature
T1-temperature difference radiator end temperature
From the above formula, it can be qualitatively concluded that when the heating value of the brake drum 10 is larger, the temperature T2 is higher, the heat dissipation efficiency of the radiator-end copper conductor 93 is higher, the temperature T1 is lower, the Seebeck coefficient SAB of the semiconductor is larger, the number of the N-type and P-type semiconductors connected in series is larger, and the thermoelectric force Δ V is larger.
When the charging battery, the charging and discharging management module 17 and the integrated thermoelectric generation piece 9 form a closed circuit, the closed circuit generates current under the driving of the thermoelectric electromotive force. The current is rectified by the rectifier bridge, then regulated by the charge management module 17, and finally the output regulated current is used for charging the rechargeable battery.
The refrigeration state of the thermoelectric generation piece is as follows: according to the following formula:
Q p ＝I×πA B
Q p heat released or absorbed by electrons passing through surfaces of different media
I-circuit current
π AB The Peltier coefficient (the difference between two different materials)
From the above formula, it can be qualitatively concluded that the Peltier coefficient pi of two media AB The larger the current I, the more heat is released or absorbed between the two media per unit time
The power storage system 18 supplies power to the integrated thermoelectric generation piece 9, the integrated thermoelectric generation piece 9 absorbs heat at the end of the brake drum 10, the copper conductor 93 releases heat at the end of the radiator, and the heat of the brake drum 10 is continuously and rapidly taken away, so that the temperature of the brake drum 10 is reduced.
When a driver frequently brakes on a long downhill, the brake pad 11 frequently rubs against the inner surface of the brake drum 10, the brake drum 10 continuously heats up, and the temperature exceeds the set temperature of the temperature sensor by 180 degrees, the charging and discharging management module 17 changes to a discharging state. The power storage system 18 begins to power the thermoelectric generation blades.
Under the electromotive force of the power storage system 18, electrons enter the N-type semiconductor from the brake drum end copper conductor 93, and the electrons need to boost energy to enter the N-type semiconductor, at which time the electrons absorb heat from the outside (the drum heat is absorbed at a reduced temperature). When electrons enter the copper conductor at the end of the radiator from the N-type semiconductor under the action of the electromotive force of the battery, the electrons need to reduce energy and radiate heat outwards (the heat is radiated to the outside through the radiator).
Under the action of the electromotive force of the power storage system 18, electrons enter the P-type semiconductor from the copper conductor at the end of the heat sink, fill positive holes of the P-type semiconductor, reduce energy, and release heat outwards (the heat is dissipated to the outside through the heat sink). When electrons enter the copper conductor at the end of the brake drum from the P-type semiconductor under the action of the electromotive force of the battery, the electrons need to raise energy, and the electrons absorb heat from the outside (the heat of the brake drum 10 is absorbed by the temperature is reduced), so that the temperature of the brake drum 10 is reduced. The heat dissipation of a water spraying system is not needed, the oil consumption of vehicles, particularly large vehicles, can be reduced, the trouble that a driver needs to add water midway is also saved, and the time and the cost are saved; meanwhile, the safety risk caused by the overheating of a braking system due to frequent braking is avoided, and the driving safety is guaranteed; the utility model has simple structure, no rotary motion part and small occupied space; the performance is stable and reliable, the service life is long, and the later maintenance is convenient; and finally, the heat energy generated during braking is collected and effectively utilized, and the energy-saving and environment-friendly concept is promoted and popularized.
It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
