摘　　要：建立了涡旋压缩机实验系统,运用非接触式测量手段—红外热成像技术,对涡旋压缩机进行了实时监测,获得了工作过程中静盘的温度场分布变化规律。通过对比不同时刻的温度场,揭示了静盘工作过程中的温度变化及形成原因,分析了热量传递的过程;深入研究了等温区分布特征与规律。根据静盘径向不同角度的温度分布规律,合理评价了温度场分布的均匀性。结合多项式拟合方法,获得了静盘径向温度与半径的实际非线性数学模型。通过红外热成像实时监测实验,可以获得涡旋盘温度场实时分布及变化规律,更好地服务于涡旋压缩机的设计与运行。An experimental system had been established in order to obtain a fixed scroll temperature field distribution during the scroll compressor working process.The scroll compressor was monitored by non-contact measurement methods-infrared thermal imaging technology.The temperature distribution and formation process of the fixed scroll had been analysed by comparing the temperature field at different moments.The heat transfer process and isotherm distribution could be investigated by the experimental results.The temperature uniformity was evaluated according to the radial temperature distribution with different angle.The relationship between the temperature and radius was nonlinear and the actual mathematical model is obtained by polynomial fitting method.The results show that the temperature field distribution can be achieved by infrared thermal imaging technology.It is beneficial for design and operation of the scroll compressor.
