摘要
在普通试验箱的基础上,研制出一种温度更低的超低温快速变温试验箱,结合超低温快速变温试验箱设计实例,重点分析了该试验箱的工作原理及设计创新思路,并给出实验结果。
An ultra-low and fast temperature test chamber is designed based on the general test chamber,which provides much lower temperature. Combining with the design example of the ultra-low and fast temperature test chamber,this paper mainly analyzes its working principles and design ideas,and then presents the experimental results.
