ABSTRACT:
In a high-temperature protective arrangement for an electronic device, which as such generates heat, the electronic device is enclosed by a heat protective enclosure provided with gaps for permitting heat removal by air convection. The heat protective enclosure is coated with a material which is subject to swelling under the action of heat to a multiple of the thickness of the original coating whereby a heat-insulating layer is formed and the gaps are closed. Electronic components of the electronic device are disposed within a housing. The heat generated by the electronic components is passed to the housing which is surrounded at a spacing substantially on all sides by the heat protective enclosure.
