Description

Изобретение относитс к электротермии и может быть использовано во всех отрасл х народного хоз йства дл нагрева теплоносител в теплооб- менных агрегатах.The invention relates to electrothermal and can be used in all sectors of the national economy for heating the heat transfer medium in heat exchange units.
Целью изобретени вл етс увеличение теплоотражающей поверхности и равномерности нагрева,The aim of the invention is to increase the heat reflecting surface and heating uniformity,
На фиг,1 изображен электронагреFig, 1 shows the electric
ватель, продольный разрез; на .2 то же, поперечный разрез; на фкг.З - узел токоподвода с нагревателем.longitudinal section; at .2 the same cross section; on fkg.Z - current lead node with heater.
Корпус 1 электронагревател , открытый со стороны торцов, выполнен в форме параллелепипеда из иеэлектро ;проводного материала. На двух противоположных боковых сторонах корпуса выполнены отверсти дл ввода подвод щих проводов к токоподводам 2.Внутри корпуса между токоподводамй расположен нагревательнь элемент 3. В качестве нагревательного элемента может быть применена, например, электропроводна кераъшка, электропровод- ньй полипропилен и другие электропровод щие композиционные материалы. Нагревательный элемент имеет сотовую структуру со СКВОЗН1ЯМИ каналами кзад ратного сечени , перпендикул рными токоподводам. Стороны каналов нагревательного элемента в его поперечномThe housing 1 of the electric heater, open from the ends, is made in the form of a parallelepiped of electrical, wired material. On the two opposite sides of the housing there are holes for the input of supply wires to the current leads 2. Inside the case between the current lead there is a heating element 3. The heating element can be, for example, electrically conductive lath, electrically conductive polypropylene and other electrically conductive composite materials. The heating element has a honeycomb structure with SCRAPERS channels of the rear section, perpendicular to the current leads. The sides of the channels of the heating element in its transverse
сечении расположены по отношению к токоподводам под углсж АЗ и npircoe- динены к токоподводам в местах пересечени стенок каналов. При толщине участков нагревател ме дчу сторонами каналов равной 8 , толщина участков между вершинами соседних каналов в плоскости, параллельной токоподводам равна 2 . Расположение сторон кана лов электронагревател под углом 45 к токоподводам обеспечивает протекание тока по всему периметру стенок каждого канала. Путь тока при этом - от токоподвода через место пересечени стенок канала по двум парам стенок к противоположному месту пересечени стенок этого же канала иThe cross sections are located with respect to the current leads under the coal AZ and npircoedins to the current leads at the intersections of the channel walls. When the thickness of the sections of the heater between the sides of the channels is 8, the thickness of the sections between the vertices of the adjacent channels in the plane parallel to the current leads is 2. The arrangement of the sides of the electric heater channels at an angle of 45 to the current leads ensures the flow of current along the entire perimeter of the walls of each channel. The current path is from the current supply through the intersection of the channel walls along two pairs of walls to the opposite intersection wall of the same channel and
так далее до противоположного токоподвода .so on to the opposite current lead.
Упом нутое утолщение участков нагревател в плоскости, параллельной токоподводам, обеспечивает выделение равной удельной тепловой мощности по поверхности стенок каналов, так как по yTojmjeHHoMy участку протекает ток, равный удвоенной величине тока, протекающего вдоль каждой стенки канала.The mentioned thickening of the heater sections in a plane parallel to the current leads provides for the allocation of an equal specific thermal power over the surface of the channel walls, since a current flows through the yTojmjeHHoMy section equal to twice the value of the current flowing along each channel wall.
Работа предложенного устройства осуществл етс следующим образом.The operation of the proposed device is carried out as follows.
При пропускании через каналы нагревател теплоносител на токопод- воды подают необходимое напр жение. Все стенки каналов равномерно и одинаково нагреваютс , а от них нагрева- етс и теплоноситель, протекающий через каналы. Эффективность нагрева обеспечиваетс за счет равномерного нагрева всех стенок каналов.When passing through the channels of the heater coolant to the current-to-water supply the required voltage. All the walls of the channels are uniformly and equally heated, and the coolant flowing through the channels is also heated from them. The heating efficiency is ensured by uniformly heating all the walls of the channels.
