ABSTRACT
Notebook computer, portability, small size, and its function meet the needs of
most people, with the step of science and technology has brought costs down,
notebook prices also acceptable to most people. With the increasing number of
problems using a laptop, notebook is exposed outside, in addition to price, most
concerned about is nothing more than the heat. Notebook in performance and
portability against heat, become the most crucial factor, notebook cooling has been a
bottleneck in the core technology of notebook. Sometimes the notebook computer will
accidentally crashes, is the general system high temperature led. In order to solve this
problem, people design the heat sink base, can make the notebook produced heat
diffusion to the computer as soon as possible outside, does not affect the use of
notebook function, not the computer line corrosion phenomenon, ensure the normal
work of notebook computer. Good base can greatly prolong the service life of
notebook computer.
The design for the radiation problem is discussed in detail, and design a set of
intelligent heat dissipation base based on single-chip microcomputer control, the
relevant factors of cost and performance, using the STC company to build the system
of STC90C51 core. In the spirit of the cost control and the market under the premise,
the circuit simple and easy mass production, save energy and intelligence in the
premise radiation function and the minimum cost.
