AI Technical Summary

Technical Problem

Existing steady-state radiative heat flow meters experience increased heat loss when the temperature difference between the ambient temperature and the radiative heat flow meter increases, leading to a decrease in measurement accuracy. Furthermore, the complex temperature control process of the blackbody furnace affects calibration accuracy.

Method used

A compensation plate is added to the heat-sensitive element, and multiple layers of heat insulation are set between the heat-sensitive element and the compensation plate. The same black heat-absorbing coating is applied. The heat loss is reduced by using multiple layers of heat insulation, and the temperature control process is simplified by calibrating with multiple temperature sensors.

Benefits of technology

It effectively reduces heat loss from the heat-sensitive element and the compensation element, improves measurement accuracy, simplifies the calibration process, and enhances the measurement accuracy of the radiation heat flow meter.
