Heater (heat gun) With Electric nozzle THROUGH cylindrical shape

摘要

The invention relates to electric appliances and is designed for directional space heating and drying surfaces with adjustable angle. Heater, wherein the supporting structure includes made from sheet steel and having a cylindrical shape covers - external and internal. On the outer casing located controls and indicators, and in the inner casing - electric heating elements and a fan. Electric heating elements are in the form of a spiral resistive wire covered with its own shell and heat-conductive dielectric multilayer wound snugly turns and windings to each other through a cylindrical nozzle in coated silica cloth layer and made of a thin metal sheet of high thermal conductivity (ENS). ENS diffuser disposed inside the heater uniformly on the inner circumference of the diffuser housing and oriented lengthwise airflow. The resistive wire is covered with an electrically insulating thermally conductive shell (braid), performed using a high dielectric filaments, the thickness of the shell is extremely small, and is determined only by the yarn thickness. This allows full air blowing fan blowing both internal and external surfaces of the casings of the heating nozzles, thereby allowing maximum heat removal and transfer to the outer space.
