| 摘要: |
| 针对测试设备既需要精度高又要求移动测试的需求，提出了一种基于新型脉宽调制技术的温
控系统方案。以某测试设备机箱为例，首先介绍了温控系统的工作原理，然后用热分
析软件对系统进行仿真分析，计算了在不同环境温度及风扇风量条件下各模块的温度，对仿
真结果进行分析并采取了改进措施，工程应用证明了该温控系统方案是可行的。 |

| Abstract: |
| A novel PWM(Pulse Width Modulation) temperature control system solution is p
roposed to meet the requirements of test equipment for both high precision and
mobile test. Taking a test equipment cabinet as example, the operation principl
e of the temperat
ure control system is introduced, then, simulation analysis of the system is ma
de with thermal analysis software，each module temperature is calculated under d
ifferent temperature and fan air volume conditions, the simulation analysis resu
l
t is analysed and improvement measures are adopted.The feasibility of the temper
at
ure control system solution is verified in engineering application. |
