Description

(54) ЭЛЕКТРОНАГРЕВАТЕЛЬ ЖИДКОСТИ(54) ELECTRIC HEATER LIQUID

1one

Изобретение относитс к энергетике и может быть использовано дл подогрева охлаждающей воды в двигател х внутреннего сгорани .The invention relates to energy and can be used to preheat cooling water in internal combustion engines.

Известен электронагреватель жидкости, содержащий перфорированный центральный и периферийный трубчатые электроды, между концами которых установлена изолирующа втулка 1.A fluid electric heater is known, comprising a perforated central and peripheral tubular electrodes, between the ends of which an insulating sleeve 1 is installed.

Недостатком такого электронагревател вл етс низка надежность и экономичность , обусловленные повыщенным расходом электроэнергии.The disadvantage of such an electric heater is low reliability and efficiency, due to the increased power consumption.

Цель изобретени повышение экономичности и надежности при горизонтальном расположении электродов.The purpose of the invention is to increase the efficiency and reliability with the horizontal arrangement of the electrodes.

Указанна цель достигаетс тем, что между противоположными концами и средним участком последних установлены дополнительные изолируюд1ие втулки, приче.м в нижней части периферийных электродов и верхней втулок, расположенных между концами электродов, выполнены сквозные отверсти .This goal is achieved by the fact that between the opposite ends and the middle section of the latter, additional insulating sleeves are installed, moreover, through holes are made in the lower part of the peripheral electrodes and the upper sleeves located between the ends of the electrodes.

На чертеже изображен электронагреватель жидкости.The drawing shows a fluid heater.

Устройство содержит горизонтально размещенные перфорированные в нижней части центральный 1 и периферийный 2 трубчатые электроды, между концами и средним участком которых установлены изолирующие втулки 3, 4 и 5.The device contains horizontally placed perforated in the lower part of the Central 1 and peripheral 2 tubular electrodes, between the ends and the middle section of which are installed insulating sleeves 3, 4 and 5.

В верхней части изолирующих втулок 3 и 5 и в нижней части периферийного электрода 2 выполнены сквозные отверсти 6 и 7 и 8. К нижней части периферийного электрода 2 прикреплена камера 9, а в нижней части центрального электрода 1 выполнены отверсти 10. На торцах периферийного электрода 2 размещены патрубки И и 12 дл подвода нагреваемой и отвода нагретой жид-кости .Through holes 6 and 7 and 8 are made in the upper part of insulating sleeves 3 and 5 and in the lower part of peripheral electrode 2. Chamber 9 is attached to the lower part of peripheral electrode 2, and holes 10 are made in the lower part of central electrode 1. At the ends of peripheral electrode 2 And and 12 nozzles are placed for supplying heated and discharging heated liquid.

Claims

The heated liquid enters the electric heater through the pipes 11 and 12, and then through the holes 6 and 7 of the insulating sleeves 3 and 5 fills the interelectrode space of the heater. Since the liquid is not completely heated, it can escape from the interelectrode space through the holes 6 and 7 in the insulating sleeves 3 and 5, it boils. The resulting vapor accumulates in the upper part of the interelectrode space, squeezing 1 portion of the heated liquid through the holes 10 of the perforated lower part of the central electrode, and through the holes 6 and 7 - a portion of the vapor with the heated liquid. When extruding liquid and vapor from the interelectrode space, the liquid level in the latter decreases, and the surface of the electrodes wetted by the liquid decreases, which leads to a decrease in vaporization in the interelectrode space. Reducing vaporization the heated fluid through the holes 10 of the perforated central electrode 1 and portions of steam and the heated liquid through the holes 5 and 7 of the insulating sleeves 3 and 5. Heated liquid and steam squeezed out of the interelectrode space, mixed with flow through the nozzles 11 and 12, and the resulting mixture is discharged to the consumer by two oppositely directed streams. The power of the electric heater depends on the cross section of the holes 6 and 7 in the insulating sleeves 3 and 5 and on the temperature of the liquid in the cooling system. the space is removed to chamber 9 through apertures 8. Claims of the invention Electron is a liquid agitator containing Vl -; J 4 .. ir ......., 1 ... V well ..} f is a perforated central and peripheral tubular electrodes, between the ends of which there is an insulating sleeve, characterized in that, in order to increase efficiency and reliability when the electrodes are horizontally positioned, additional insulating bushes are installed between the opposite ends and the middle section of the electrodes, and through holes are made in the lower part of the peripheral electrode and the upper bushes located between the ends of the electrodes.
