Abstract

The heater has a heating element (1) made of carbon or ceramic. The element is supplied with electricity. A working fluid (3) is circulated over the element and carries heat away to be circulated to radiators to provide heating of rooms and other spaces. The heat output can be increased by fitting several carbon or ceramic elements into the heat transfer region, with the working fluid circulating faster to carry away the extra heat generated. The heating elements can be electrically in series or parallel, and can operate from alternating or direct current. Manual and automatic controls can be fitted to regulate flow of current to produce the required temperature.

Description

HEATING DEVICE

  SAVING ENERGY

  The Oresen: The invention relates to a heating device making it possible to achieve energy savings. Traditional electric heating systems are generally made with metallic resistors of low electrical resistance which increase energy consumption. In these systems the heating is carried out by infrared radiation having the drawback, during a thermostatic cut-off or of a reduction in the electric consumption, of causing an unpleasant sensation of hot and cold, the metallic resistance having a low thermal inertia. it cools down very quickly and requires a lot of energy each time the appliance is restarted to maintain the temperature

chosen.

  These systems having a resistance to incandescent burn the surrounding oxygen. The device

  according to the invention overcomes these drawbacks.

  Its heating principle is not incandescent, it does not change the humidity and does not consume oxygen at the place where it works. : l remains as efficient as central heating without heat loss in the

  pipes. -i1 does not pollute and respects the environment.

  This device can be fitted with a znosommat regulation: in electric: it increases energy saving

  without decreasing the temperature by avoiding the unpleasant

feeling hot and cold! d.

  According to a particular embodiment, the present invention consists of a primary source (1) energized, which consists of one or more rods or tubes based on carbon and

  ceramic already known in the industry.

  This material has advantages, among others - possibility of obtaining a large range of electrical resistance - a low specific thermal capacity

  - a resistivity in the mass of the material.

  Figure (1) shows the heating element and the

  figure (2) the assembly of the elements.

  The heating device comprises a heating element composed of a carbon and ceramic source (1) connected to an energy source and of a heat transfer element (3) Providing good thermal conduction while being electrically isolated from the primary source; said device

  also includes a dissipating element (4).

  According to the invention, a heating element is introduced

  in a body (2) and according to another characteristic of-

  the invention, the dissipation element (4) is in contact with the

body (2).

  It is possible to mount several heating elements in a dissipation element. Said heating elements being electrically connected either in series or in parallel. Power can be supplied from a direct current source or from a source. alternating current. According to another characteristic of the invention, the heat transfer element (3) can also. depending on its form and nature, fulfill the functions of a dissipation element (4)

  which removes the body (2).

  This device according to the invention can be provided with an electrical consumption regulation system

- manual dimmer.

- automatic dimmer.

- temperature detector.

  These allow you to maintain a desired temperature

  while reducing power consumption.

  Characteristics of the primary source material

  (1) allow it to be painted at high temperatures for low power consumption.

  The heat transfer element (3) plays a role in transmitting the heat produced by the primary source (1) (see igure 1), without pressure loss, therefore the heat transfer element (3) must be light and have a low

mass thermal capacity.

  i! also allows electrical isolation of the primary source.

  With reference to figure (2), the body (2) aims to distribute the heat produced by the primary source (1) over

  a larger surface area for exchange with air.

  It is made with a good conductive uhermicue material. Directly, said material is brought into contact with the body (2), a heat dissipation element (4)

  Allows to channel and dissipate the stored heat.

on the heating element.

  By its large surface of exchange with air, the element '

  (4) maintains convection.

  According to the invention, several heating elements, with ----- 2_ or without body, can be mounted in a heating element.

  dissipation (4) to increase the thermal power.

  USE: the fields of application of this

invention are not exhaustive.

It can serve the public

- domestic heating.

  - hot water tank, - transport (heating of the passenger compartment of electric cars, train sets, RER. metro, passenger compartment of airplanes, etc.)

  - the heating of large surfaces, cinemas, ...
