The temperature united for controlling cooling system according to temperature value.
In the present embodiment, cooling system includes heat-dissipating pipe, and heat-dissipating pipe uses the material with Thermal conductivity to be made, can
It is contemplated that cooling system can also include other radiator structures or heat-conducting medium, to reach good heat dissipation effect.
In the present embodiment, temperature sense system includes one to four temperature sensor.Temperature sensor is uniformly arranged on scattered
Around hot systems, with quick, the accurate temperature value for obtaining cooling system.
In the present embodiment, temperature-controlling system includes main control module and cooling module.Wherein, the output end of each temperature sensor
Connect with the input terminal of main control module so that the temperature value of cooling system is sent to main control module, the output end of main control module with
The input terminal of cooling module is connected to control the working condition of cooling module, and cooling module is used to cool down to cooling system.
In the present embodiment, main control module includes MCU microprocessor, also may include single-chip microcontroller, arm processor or FPGA.
In the present embodiment, cooling module includes fan.Microprocessor controls rotation speed of the fan according to the temperature value of heat-dissipating pipe, reaches
To the purpose to cool down to heat-dissipating pipe.Wherein, main control module further includes memory, and memory is stored with temperature sensor reading and wind
The corresponding relationship of revolving speed is fanned, the corresponding relationship is as shown in table 1:
The temperature value of 1 heat-dissipating pipe of table and the corresponding relationship of rotation speed of the fan
| Temperature sensor reading | Rotation speed of the fan |
| 50~60 | 50% |
| 60~70 | 70% |
| 70~80 | 100% |
| ≥80 | Shutdown |
Referring to table 1, temperature sensor reading and rotation speed of the fan are proportional to: when temperature sensor reading is 50~60
When, rotation speed of the fan is the 50% of maximum value；When temperature sensor reading is 60~70, rotation speed of the fan is the 70% of maximum value；
When temperature sensor reading is 70~80, rotation speed of the fan is maximum value, it is seen then that temperature sensor reading is bigger, i.e. heat-dissipating pipe
