70 temperature is connected the first thermoelectric pile 40 when being higher than second temperature value and radiates to electric-controlled plate 70.And first thermoelectric pile 40 be
Automatically controlled plate temperature is connected under conditions of being higher than second temperature value, avoids the occurrence of that 70 temperature of electric-controlled plate is lower, nature of electric-controlled plate 70
The first thermoelectric pile 40 is connected when needing in the heat dissipation that heat dissipation has been able to meet electric-controlled plate 70, waste energy is avoided, thus this implementation
Electric-controlled plate cooling control method in example has saved energy while guaranteeing to 70 better heat dissipation effect of electric-controlled plate.
Further, second temperature value is preset fixed value, actual temperature change model when can be worked according to circuit board
Enclose setting.The preferred second temperature value of the present embodiment is 35 DEG C, and under general condition, the temperature of electric-controlled plate 70 is higher by one than environment temperature
When definite value, illustrate that the natural heat dissipation of electric-controlled plate 70 is no longer satisfied the heat dissipation needs of electric-controlled plate 70.
Further, step S4 includes:
S41, the controller 30 obtain the third temperature value of setting, if the controller 30 judges the automatically controlled plate temperature
Greater than the third temperature value, then controls first thermoelectric pile 40 and be connected；
S42, the controller 30 obtain the 4th temperature value of setting, if the controller 30 judges the automatically controlled plate temperature
Greater than the 4th temperature value, then the conducting of the second thermoelectric pile 50 is controlled；
S43, the controller 30 obtain the 5th temperature value of setting, if the controller 30 judges the automatically controlled plate temperature
Greater than the 5th temperature value, then the conducting of third thermoelectric pile 60 is controlled；
Wherein, the 4th temperature value is greater than third temperature value, and the 5th temperature value is greater than the 4th temperature value.
Specifically, when environment temperature is higher than the first temperature value, if controller 30 judge the temperature of electric-controlled plate 70 greater than the
Three temperature values and be not more than the 4th temperature value, controller 30 control the first thermoelectric pile 40 conducting；If controller 30 judges electric-controlled plate
70 temperature is greater than the 4th temperature value and is not more than the 5th temperature value, under the premise of the first thermoelectric pile 40 has been turned on, control
Device 30 controls the conducting of the second thermoelectric pile 50；If controller 30 judges that the temperature of electric-controlled plate 70 is greater than the 5th temperature value, in the first heat
Under the premise of pile 40 and the second thermoelectric pile 50 have been turned on, controller 30 controls third thermoelectric pile 60 and is connected.
In this way, the electric-controlled plate cooling control method in the present embodiment can be higher than the first temperature value and electric-controlled plate in environment temperature
70 temperature radiates to electric-controlled plate 70 when being higher than third temperature value.And the heat of conducting can be selected according to the temperature of electric-controlled plate 70
The temperature of the quantity of pile, electric-controlled plate 70 is higher, and the thermoelectric pile of conducting is more, and such heat dissipating method is more reasonable, avoids
All simultaneously turning on multiple thermoelectric piles in any case leads to the case where wasting energy.
Further, third temperature value, the 4th temperature value, the 5th temperature value are preset fixed value, can be according to automatically controlled
Temperature change in the work of plate 70 is set.The preferred third temperature value of the present embodiment is 40 DEG C, and preferably the 4th temperature value is 50 DEG C,
It is preferred that the 5th temperature value is 60 DEG C.
Embodiment 6
Electric-controlled plate cooling control method as described above, the present embodiment are different from place and are, the third temperature
Value is greater than the second temperature value.
Specifically, the temperature of electric-controlled plate 70 is connected when being higher than second temperature value when environment temperature is lower than the first temperature value
First thermoelectric pile 40；When environment temperature is higher than the first temperature value, the temperature of electric-controlled plate 70 is connected the when being higher than third temperature value
One thermoelectric pile 40.When environment temperature is lower, electric-controlled plate 70 is easy to ambient enviroment heat release, and the natural heat dissipation of electric-controlled plate 70 is stronger；
When environment temperature is higher, electric-controlled plate 70 is difficult to ambient enviroment heat release, and the natural heat dissipation of electric-controlled plate 70 is weaker.Under normal circumstances,
No matter how high environment temperature is, the first thermoelectric pile 40 of conducting should all be chosen whether according to the temperature of electric-controlled plate 70, it is meant that step S31
Temperature with electric-controlled plate 70 when the first thermoelectric pile 40 being connected in step S41 should be identical, should be third temperature value.However,
In step S31, if the first thermoelectric pile 40 is connected when automatically controlled plate temperature is higher than third temperature value in selection, in this case,
Even if illustrating that environment temperature is lower, the natural heat dissipation of electric-controlled plate 70 is stronger, the temperature of electric-controlled plate 70 also has reached third temperature value,
Even if illustrating that the natural heat dissipation of electric-controlled plate 70 at this time is stronger, also it is not enough to slow down the rising of 70 temperature of electric-controlled plate, represents electric at this time
The state for controlling plate 70 should be that temperature has zooming trend.Under this state, if being had increased in automatically controlled plate temperature
The first thermoelectric pile 40 is connected after third temperature value again, can greatly increase and the consumed energy that radiates is carried out to electric-controlled plate 70, and
Optimal heat dissipation opportunity may be missed, causing electric-controlled plate 70, temperature rapid increase, may damage to electric-controlled plate 70.
In this way, preferred third temperature value is greater than second temperature value in the present embodiment, can have quickly in the temperature of electric-controlled plate 70
When the trend of rising, the first thermoelectric pile 40 of conducting radiates to electric-controlled plate 70, can greatly slow down the upper of 70 temperature of electric-controlled plate
The trend of liter, avoids temperature rapid increase from damaging to electric-controlled plate 70, thus the electric-controlled plate cooling control method in the present embodiment
Have the function of protecting electric-controlled plate 70.It also can avoid carrying out heat dissipation institute to electric-controlled plate 70 caused by the rapid increase because of automatically controlled plate temperature
The increase of the energy of consumption, so that the electric-controlled plate cooling control method in the present embodiment is also equipped with good energy-conserving action.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
