Abstract

Heating Source is characterized by the fact it takes advantage of heat generation when electricity is forced to pass through a metallic element or other electric conductive material, placed in a hermetically sealed container and filled with an inert gas. This heating system would be used in place of the elements actually used in devices where the elements are directly exposed to the atmosphere's oxygen. The Unit has advantages in handling, cleaning, lower manufacturing and functioning cost, no danger of electric discharge, any residual particles or toxics gas spreading in the atmosphere.

Description

"DESCRIPTION"

Heating Source is characterized by the fact it takes advantage of heat generation when electricity is forced to pass through a metallic element or other electric conductive material, placed in a hermetically sealed container and filled with an inert gas. This heating system would be used in place of the elements actually used in devices where the elements are directly exposed to the atmosphere's oxygen. The Unit has advantages in handling, cleaning, lower manufacturing and functioning cost, no danger of electric discharge, any residual particles or toxics gas spreading in the atmosphere. As Heating Source can also be of opaque materia! since is not used for illumination, with the advantage of using other not transparent or translucent materials.

The enormous experience and existing technology involved in the production of electric light is used in this invention. The Heating Source can be used in the incandescent state, or on a lower temperature. The Heating Source can be made in different shapes, materials and others characteristics in accordance with their particular application.

Tungsten is a good material, because it has a higher melting point, close to 3,700° K, which is slightly less than carbon at 3,800° K. No element can provide the heat necessary for solar light, (6,600° K in the solar photosphere) without melting. When producing light by hot element, most of the energy is converted into heat instead of light. The electric iron, electric shower and many other electric appliances have the element exposed to the oxygen in the atmosphere. They use the heat produced when filaments become incandescent.

It can be observed that the light emitted by an incandescent lamp is not the direct effect of the electric current, but a consequence of the heating of the filament produced by the passage of the electric current. This is the property used in the incandescent lamp and results in more heat than light being generated. Only 5% to 10% of the energy is transformed into light. This condition makes it really advantageous that the Heat Source be used as a source of heat in appliances.

If exposed to the air, tungsten filaments would be quickly destroyed due to the action of the oxygen. In the beginning a vacuum has been used inside the light bulb to prevent this action. Due to the high temperature, the tungsten is deposited on the walls of the bulb, which causes the filament to become weak and break in a short time.

Some lamps are filled with an inert gas (normally argon) in place of a vacuum to reduce vaporization, but the lamp life was still short (about 1000 hours in normal use). The halogen lamp uses the same principle as the incandescent lamp, but the gas is in general krypton or xenon with small quantities of a halogen element (usually bromine or iodine). The halogen has the property of combining with the atoms of the evaporated tungsten and depositing back on the filament In other words, a recycling process. Therefore, the working temperature can be higher, which increases the efficiency. The bulbs are smaller, closer to the filament and made of quartz to support high temperatures and pressures that can be up to 25 bars. These results in a longer medium life (3000 h) and higher energies, about 50% more than the not halogen incandescent lamps.

The Heating Source has a lot of advantages over the traditional production of heat by an element in contact with the atmosphere, such as:

A - The ability to generate higher temperatures.

B - Located in an hermetic enclosure, the heating source is not as exposed to handling dangers from the heat and electricity and ecological clean.

C - Located in a hermetic enclosure, it does not suffer deterioration due to exposure to oxygen, which will promote longer element life.

D - Lower cost and lower energy consumption than the elements in contact with the atmosphere.

E -There is no restriction to substitute the heating electrical element as describe in this patent for heating element in contact whit the oxygen of the atmosphere.

Just to have an idea and better conception of the present Patent of Invention, it is shown hear under the electric cloth iron. It consist in a hermetic enclosure (fig 4), filed up with an inert gas. Upper part of the enclosure has isolate material to protect the hand against heat, (fig 2) is an upper view of the element, (fig 3) is a lateral view where can be seen the element, (fig 5) show the base of the iron, (fig 6) is a external lateral view of the iron. Electricity comes through a cable protected against heat with a ceramic tube, which is sealed to not allow gas escape. A dimmer control the electric current intensity
