摘　　要：重力梯度仪平台当环境温度在0~40℃范围内变化时,要求其内部的重力梯度测量装置能始终工作在30℃左右。这需要用到双向温控技术,将半导体制冷应用于重力仪平台。文中介绍了双向温控结构设计的整个过程,给出了制冷功率的确定方法,阐述了隔热保温对温控精度、温控功率及系统体积的影响,分析了风路设计的关键点,总结了散冷、散热风机各自选取的原则和风路设计方法,并利用热仿真分析验证了设计的合理性。该设计达到了系统总体要求,满足重力仪平台高精度工作的环境要求。When the environment temperature changes in the range of 0 ~ 40℃,the gravity gradient measuring device should work at30℃. This requires the use of bidirectional temperature control technology,and the semiconductor refrigeration technology should be applied to gravity meter platform. In this paper,the whole process of the structure design of bidirectional temperature control is introduced,and the method of determining the cooling power is given. In addition,the effects of heat insulation and heat preservation on the accuracy of temperature control,temperature control and the volume of the system are described. The key points of the design are analyzed. The principle and the method of the design of the wind turbine are summarized,and the rationality of the design is verified by the thermal simulation analysis. The design can meet not only the requirement of the system but also the requirement of the high precision of the gravity meter platform.
