Приборы с толстопленочным нагревательным элементом

The results of investigation of the parameters of portable electric stoves. The objective of our research is to create a modern compact electric with high efficiency at least 85%, and durability of at least 10 000 hours. A new energy-efficient design of portable electric. The heating layer of flat steel heater is uniformly distributed throughout the area, which provides a low temperature gradient on the work surface. The total thickness of the substrate, which caused the heater, insulating, heating and protective layers in the range of 3-4 mm, thus achieving a low heat electric. Due to this heating occurs within 1 min, the efficiency reaches 85%. The use of flat steel heater ensures durability electric at least 10 000 hours. It is shown that the design has a high economic performance.
