基于单片机的智能散热器的设计

摘 要:散热器在生活中的应用很广泛，例如笔记本电脑会因为散热不良而出现死机现象。单片机具有集成度高、体积小、功能强、可靠性高、价格低廉等优点，广泛应用于工业测控、智能仪器仪表、网络通信、家用电器等领域。矚慫润厲钐瘗睞枥庑赖。 本设计在深入探讨散热问题的基础上，设计出了一套基于单片机控制的智能散热器，综合了成本和性能等相关因素，采用Atmel公司的AT89C52单片机为核心。控制器件向温度传感器DS18B20发送指令，进行温度信号的采集与处理，并通过液晶显示器显示出来，与系统预先设定的温度参数进行比较，当温度达到一定数值后，单片机会驱动风扇转动，进行散热处理。当温度下降到一定数值后，风扇停止工作。通过按键对温度参考值进行设定，利用记忆芯片EEPROM对设定值进行保存，实现温度智能控制最后系统在Protues下仿真运行，验证此系统设计正确可行。聞創沟燴鐺險爱氇谴净。 关键词：散热器；单片机 ；智能控制

Intelligent design of radiator

Abstract： Radiator wide range of applications, such as notebook computers

because of poor heat dissipation phenomenon of death in life. MCU with high integration, small size, strong function, high reliability, low price, etc., are widely used in industrial measurement and control, smart instrumentation, network communications, household appliances and other fields.残骛楼諍锩瀨濟溆塹籟。 The design in depth heat problem on the basis of design of a microcontroller-based control of intelligent radiator, a combination of cost and performance, and other related factors, using Atmel AT89C52 microcontroller as the core. Control devices to send commands to the temperature sensor DS18B20 temperature signal acquisition and processing, and LCD display parameters were compared with the pre-set temperature when the temperature reaches a certain value, the microcontroller will drive the rotation of the fan for cooling treatment. When the temperature drops to a certain value, the fan stopped working. Set through the button on the temperature reference value, the use of memory-chip EEPROM to save the set value, temperature intelligent control the final system Profuse under simulation run to verify that the design of this system is correct and feasible.
