Description
Изобретение относитс к электрическим на .гревател м, которые могут быть применены при высокой стабильности работы в течение .длительного времени в услови х высоких температур и агрессивных сред.The invention relates to electric heaters that can be used with high stability of operation for a long time under conditions of high temperatures and corrosive media.
Известны электро-нагреватели, содержащие токопровод щий элемент на основе графита и защитную оболочку из иитрида бора. Эти натреватели обладают недостаточно высоким удельным объемом выделенной энергии.Electro-heaters are known which contain a conductive element based on graphite and a protective sheath of boron iitride. These natrevateli have not high enough specific volume of energy released.
В предлагаемом электронагревателе токонровод щий элемент выполнен из пиролитического графита с кристаллографической осью, перпендикул рной оси нагревател .In the proposed electric heater, the current-conducting element is made of pyrolytic graphite with a crystallographic axis perpendicular to the axis of the heater.
Такое выполнение позвол ет з начительно увеличить объем выдел емой энергии и повысить рабочий температурный предел нагревател . Кроме того, применение оболочки из пиролитического нитрида бора :с кристаллографической осью, параллельной оси нагревател , снижает тепловые потери в радиальном направлении .This embodiment allows to significantly increase the amount of energy released and increase the operating temperature limit of the heater. In addition, the use of a shell of pyrolytic boron nitride: with a crystallographic axis parallel to the axis of the heater, reduces heat loss in the radial direction.
Дл более интенсивной теплоотдачи через диэлектрическую оболочку ее выполн ют в виде набора шайб из пиролитического нитрида бора, кристаллографическа ось которых перпендикул рна оси нагревател .For more intense heat transfer through the dielectric shell, it is made in the form of a set of pyrolytic boron nitride washers, the crystallographic axis of which is perpendicular to the axis of the heater.
На фиг. 1 показам вариант предлагаемого нагревател с кристаллографической осью термического графита, перпендикул рной оси нагревател , и защитной оболочкой из нитрида бора; на фиг. 2 - нагреватель, защитна оболочка которого СОСТОИТ из пиронитрида бора в виде набора щайб с кристаллографической осью, перпендикул рной оси нагревател .FIG. 1 shows a variant of the proposed heater with a crystallographic axis of thermal graphite, perpendicular to the axis of the heater, and a protective shell of boron nitride; in fig. 2 - a heater, the protective shell of which consists of boron pyronitride in the form of a set of shields with a crystallographic axis, perpendicular to the axis of the heater.
Электрический нагреватель содержит токопровод щие элементы 1 к 2, диэлектрические оболочки 3 w. 4, штрихами обозначено направление кристаллографической оси а токопровод щего элемента и диэлектрической оболочки.The electric heater contains current-conducting elements 1 to 2, dielectric shells 3 w. 4, the strokes indicate the direction of the crystallographic axis of the conductive element and the dielectric shell.
