1、 摘摘 要要 笔记本电脑，便于携带，体积小，而且它的功能满足大多数人的需要，随着科学 技术的近步带来的成本下降，笔记本的价格也为大多数人所接受。随着使用笔记本人 数的增加，笔记本的各种问题也暴露出来，除了性价比之外，最关心的莫过于散热。 笔记本在性能与便携性对抗中，散热成为最关键的因素，笔记本散热一直是笔记 本核心技术中的瓶颈。有时笔记本电脑会意外的死机，一般就是系统温度过高 导致。为了解决这个问题，人们设计了散热底座，可以使笔记本产生的热量尽 快的扩散到电脑外部，不影响笔记本的使用功能，不会使电脑的线路出现腐蚀 现象，保证笔记本电脑的正常工作。好的底座可以很大的延长笔记本电脑使用 寿命。 本

2、设计针对散热问题做了深入的探讨，并设计出一套基于单片机控制的智能散热 底座，综合了成本和性能等相关因素，采用了 Atmel公司的 AT89S52 为核心搭建了 该系统。在本着成本控制和推向市场的前提下，文中的电路简约而易于批量生产，在 完成散热功能和最少成本的前提下达到了节能和智能。 关键词关键词：散热底座；单片机；智能控制 ABSTRACT Notebook computer is portable and small, and its functions could meet the needs of the majority, with the developing of science

3、 and technology, the cost decline, and the price of the laptop base to be acceptable to most people. But with the increase in the number of using the laptop people, they exposed various problems, in addition to cost, people always concerned about dissipating heat extremely. In the confrontation of t

4、he laptops performance and portability, the most critical factor is dissipating heat, and laptops dissipating heat has been the bottleneck of the core technology. Sometimes it end up unexpected, it is always because of that the system temperature is too high. To solve this problem, people have desig

5、ned heat dissipation base, the heat can remove from the laptop to the outside as quickly as possible, it does not affect the use of laptop, and its electronic line will not be eroded, to ensure the normal operation of laptop. A good base could extend the life of laptop. This design makes an in-depth

6、 discussion about heat dissipation, and design a microcontroller-based intelligent control of cooling base, synthesize cost and performance and so on, using the core AT89S52 Atmel Corporation built the system. Under the premise of cost and market, the circuit in this design is simple and easy-to-volume production, it can be intelligent and energy-saving under the premise of heat dissipation and minimum cost.
