摘要:
An electric heater for a motor vehicle uses heat generated by power semiconductors as the heat source. The heat output by the power semiconductors is used directly for heating. The power semiconductors are regulated by circuit regulators to be able to adjust the heating power continuously. In addition, switching devices are provided which interrupt or shut down the respective branch circuits individually in the event of short circuits in the power semiconductors.

The invention pertains to the electrothermal field and in particular to the resistive heating elements on the basis of the glass-fibre textile with the pyrocarbon coating and may be used for the production of the heating elements in heaters for both industrial and domestic applications. For obtaining the electrically conducting textile with the wide range of resistance and for broadening its sphere of application, as well as lowering the deposition temperature and retaining low scattering of the resistance along the whole field of the textile, the said textile contains 0.2-15% weight of pyrocarbon of turbostrate structure with hydrogen content up to 2% weight and with density of 0.8-1.5 g/cm3, and 86.0-99.8% weight of glass-fibre textile with the softening temperature at least 650° C. The raw hydrocarbon materials used for pyrocarbon production are hydrocarbon oils with the viscosity of 8 to 23 sSt, which are preliminarily heated to 350-450° C. and in the flow of the inert gas are put through the nozzle with the developed surface at the temperature of 450-500° C., while the deposition of the pyrocarbon out of the chemical vapour is effected at 600-800° C. with the subsequent degassing of the obtained textile at 350-450° C. in the vacuum.
