The infrared imaging characteristics of heating-radiator faults

There are various faults in the running of heating-radiator which have severely impacted on heating-radiator system operation. It is desired to develop an objective methodology to predict the heating-radiator faults instead of experiential judgment. On the infrared temperature-measuring principle, the temperature field will distort when some faults happen in the running of heating-radiator. To identify heating-radiator faults better, the fault modes of heating-radiator are approximately divided into three types-quality fault, corrosion fault, and running fault. With the infrared imaging characteristics of the surface temperature of heating-radiator, the faults of the copper-aluminum radiator and irregular-tube radiator can be detected combining heating-radiator's structure, technics and running conditions. The results proved that the infrared thermal imager is a novel, effective and visual approach to detect heat-radiator faults and have a wide application prospect.
