<p>PURPOSE:To provide a heat control device for a heat-insulating outer-frame structure by utilizing a temperature detecting, means using cables. CONSTITUTION:Optical fibers 3 and 5 are provided at the inside and the outside of a temperature-difference detecting layer 8, which is provided in a heat- insulating outer frame 2, respectively. Laser pulses are inputted into the respective optical fibers 3 and 5 from a temperature detector 7. The generated part of the scattered light and the temperature are computed based on the intensity and the arriving time of the Raman scattered light reaching the device, and the heat flux is obtained based on the thermal conductivity and the temperature difference.</p> |
