ABSTRACT:
A method and apparatus for measuring the heat transfer in cooling devices. More particularly, the invention is concerned with the heat transfer pattern caused by blastheads used in the tempering of automotive glass. A thin foil sheet disposed in front of the blasthead is heated according to a predetermined pattern. One side of the foil sheet is then exposed to a cooling blast of air from the nozzles of the blasthead, while the temperature of the opposite side of the foil sheet is monitored using an infrared camera. Then, using information generated by the infrared camera, heat transfer information can be determined.
