为了测试管状保冷材料及其结构在其所使用温区的表观导热系数，研制了在一维、径向、稳态传热条件下测试管状保冷材料及结构低温导热系数的防护端型微机监控装置．该装置具有自动输液、自动巡回检测温度、自动控温等多种功能．应用分散式数据检测器ＩＭＰ３５９５１Ｃ和ＩＭＰ３５９５１Ｄ，具有漂移小、波动小、反应快及精度高等特点，装置的总体误差不超过３％．为保冷结构设计提供低温导热系数数据．
In order to test the apparent thermal conductivity of tubular cold-protective materials and their structures in the temperature range of their use, a protective-end microcomputer monitoring system for testing the tubular cold-preservation materials and the low-temperature thermal conductivity of the structures under the conditions of one-dimensional, radial and steady heat transfer was developed Device. The device has automatic infusion, automatic tour detection temperature, automatic temperature control and other functions. Application of distributed data detector IMP35951C and IMP35951D, with small drift, small fluctuations, fast response and high accuracy, the overall error of the device does not exceed 3%. Provide low temperature thermal conductivity data for cold insulation design.
