摘要
转换效率是我们在生活中最看重的,能把物质利用到最大化。能量大部分都被消耗在热能,所以提高散热是最为关键。智能散热器的设计是为了满足在开关电源中提高开关管效率进行需求而做的课题,具有较为广阔的市场前景。
本文介绍智能散热器的设计是针对开关电源中开关管散热而设计开发工作。在电源设计中散热决定了该电源的稳定性与可靠性。智能散热器整体设计是围绕低成本,模块化,可扩展和寿命长的特点。单片机采集功率器件的环境温度进而去控制风扇的旋转,并能自动根据温度的变化调整转速,在现实中有着非常广泛的应用,
该智能散热器系统可广泛应用于开关电源而设计,完全脱离人工操作,并可以通过远程监视、控制,真正实现了智能控制,目前已经在极高压电源上系统中使用。

ABSTRACT
The conversion efficiency is our most valued in life, can make to maximize the material utilization. Most of the energy is consumed in the heat, so as to improve the heat dissipation is the key. The design of intelligent radiator is to meet the increasing demand for the switch efficiency of the project in the switching power supply, has a broad market prospect.
This paper introduces the design of intelligent radiator is designed for the development of the heat pipe switch in a switching power supply work. In the design of power supply cooling determines the stability and reliability of the power supply. The overall design of intelligent radiator is around the low cost, modular, extensible and long service life. The single-chip power device and the ambient temperature to control the rotation of the fan, and can automatically adjust the speed according to the change of temperature, there is a very wide range of applications in reality.
Widely used in switching power supply and design of the intelligent radiator system, without manual operation, and can be controlled by remote monitoring, and realize intelligent control, has been used in high voltage power supply system on.
Key words PWM Single chip puter temperature control
