Abstract

Изобретение относитс  к электротехнике . Целью изобретени   вл етс  повышение надежности путем теплообмена нагревател  с окружающей средой и уменьшение металлоемкости конструкции. Трубчатый электронагреватель имеет на поверхности оребрение в виде узлов из двух продольно расположенных ребер 4, соединенных перемычкой 5, причем узлы по поверхности 1 нагревател  расположены дискретно. За счет непосредственного контакта по крайней мере половины поверхности нагревател  с окружающей средой, т.е. без переходного термического сопротивлени , повышаетс  эффективность теплообмена. 2 ил.The invention relates to electrical engineering. The aim of the invention is to increase reliability by heat exchange of the heater with the environment and reduction of the metal structure. The tubular electric heater has fins on the surface in the form of nodes of two longitudinally located ribs 4 connected by a jumper 5, and the nodes on the surface 1 of the heater are discrete. Due to direct contact at least half of the heater surface with the environment, i.e. without transient thermal resistance, the heat exchange efficiency is improved. 2 Il.
