TODAY’S PATENT – HEAT SHIELD DEVICE
The Heat Shield Device was invented by Gerhard Pirchl (5708 Birrwil) on the 28th of October, 1997, bearing patent number US5680757A.
The object of the present invention is to manufacture a heat shield device of the type referred to above that may have substantially lower production costs, an improved performance over time, better corrosion resistance, improved resistance to vibration, and a lighter weight. Moreover, at least equal or better temperature insulation than conventional heat shield devices should be provided. An essential characteristic of the invention is that the heat shield device may be merely one metal plate that is used as the heat shield, that plate may have a half-open construction which surrounds the component to be shielded. The plate surface of this metal plate may have a corrugated structure on the micrometer range on at least one side but preferably on both sides.
