Description

Vertical electric radiator device with a maximum height of 2 meters for the use of homes using heat transfer fluid technology

DESCRIPTION

The invention relates to a vertical electric radiator device with a height of 2 meters maximum for the use of dwellings according to the technology of heat transfer fluid, the object of providing:

- a variation in the temperature of the entire surface of the front face of the radiator, reduced to 5% in order to optimize the diffusion of heat inside the room (instead of 10% according to the standards in force)

- and a difference in heat flow at the rear of the radiator of 10% less compared to the emission on the front panel, in that the optimization of the heat transfer in the room must favor caloric displacements towards the room.

State of knowledge

The state of the art in the technical field offers many technologies for electric radiators (convector, radiant, soft heat radiator ...). The performance of these radiators is very variable and depends on the principles of transfer of electrical energy into thermal energy. Efficiency, that is to say the ratio between the electrical power consumed and the power dissipated by the fins of the radiator is therefore at the heart of the concerns.

A first technology relates to radiators with heat transfer fluid, characterized by several patents: W02016013072, FR2816396, FR2842587, FR2865527, WO / 2005/083332, FR2961890, WO2015183192 which mention radiators which do not require a high-rise design (case of vertical radiators). The coolant technology is characterized in that a fluid includes heating resistors in contact with the parts to be heated, this fluid having properties for transporting calories. Patents mention principles of heat exchange between the heat transfer fluid and the heating body with different types of connections allowing the improvement of the transfer of calories to the heat diffuser. The claims of these patents mainly relate to the principles of connection between the resistance element and the diffuser element, without the transmission performance of the components themselves being at the heart of the concerns, these being reduced to problems of footprint. So that the state of the technology by coolant does not allow in the state to optimize the performance of thermal restitution. In the case of this patent to design a vertical radiator optimizing the return of heat in the room, the dimensional (vertical) characteristic of our specifications further amplified this problem of caloric transfer performance.

Another technology called heat pipe radiators, such as the patents: WO / 2014/171736, EP1700076, W02005054766, W02004048855, is characterized in that a liquid contained in a closed volume changes phase (from the liquid state to the state gas) when it rises in temperature. More particularly with these patents, these describe industrial applications in the fields of electronics or aeronautics, this technology is reduced to objects of reduced size and is not suitable for radiators of large size, such as used in residential areas, in that they have a major drawback which is to make noise, which is very disturbing in domestic use.

This latter technology is not to be confused with the technology of air conditioners, which differs from the latter in that they use gas compression and expansion (not applicable to the field of our invention).

Consequently, existing radiator technologies do not offer an appropriate solution for limiting the size of electric radiators in dwellings with limited surface areas, while optimizing the performance of heat recovery. This is what the present invention attempts to remedy.

Presentation of the invention

The invention relates to a vertical electric radiator device with a height of 2 meters maximum for the use of dwellings according to the coolant technology, allowing:

- a variation in the temperature of the entire surface of the front face of the radiator, reduced to 5% in order to optimize the diffusion of heat inside the room (instead of 10% according to standards in force),

- and a difference in heat flow at the rear of the radiator of 10% less compared to the emission on the front panel, in that the optimization of the heat transfer in the room must favor caloric displacements towards the room, characterized by :

a vertical diffuser (a) not more than 2 meters long, depending on:

o a central structure of tubular shape (b) called to receive the resistance (c) and the heat transfer fluid and placed more or less in the center of the radiator, o receiving diffusion fins oriented on either side of a vertical plane In a way that :

four fins are placed on the four corners of the perimeter (d) of the projected surface of the diffuser, thus offering a cross shape, four other fins (e) forming another cross between the four fins of the four corners of the perimeter and placed at intervals regular between the fins forming the four corners, all of these fins bearing on the central structure of tubular shape (b) so as to ensure the diffusion of heat, the fins placed on the side of the part to be heated (f) being longer than those (g) placed on the wall side, so as to favor a diffusion of heat in the living room, other fins (h) finally, placed parallel to the wall and bearing on the fins acting as cross (d and e), having the objective of ensuring both a mechanical resistance of the assembly and participating in the diffusion of heat, a cylindrical resistance (c) coaxial with the tubular shape of the struct ure, whose length is from 1400 mm to more or less 15% of its length, placed in the lower part of the diffuser, made in two separate parts whose powers can vary from one another:

a first lower part (i) with a length of 200 mm long at plus or minus 15%, of which the proportionally greater power representing approximately half of the power of the resistor, a second part (j) placed in the continuity of the lower part, over the entire differential length, a ring (k) which is placed more or less at the junction of the two parts of the resistance, forming a protrusion for the purpose of partially blocking the flow of the heat-transfer fluid (I ) contained in the central structure of the diffuser, in such a way that the fluid placed as close as possible to the first lower part (i) of the resistor (which has a large power over a reduced space) is braked in this part, a thermostatic probe (m) placed at the top of the resistor which cuts the electrical supply to the resistor at a programmed temperature, and also activates it at a lower established temperature,

The space inside the central tubular structure (b), at the location of the positioning of the ring (k), is dimensioned to still allow the fluid to pass between the low and high part of the resistance (vs). According to this principle, the lower part of the structure having received a large thermal power in a restricted space heats the heat-transfer fluid (I) in a way much higher than that heated by the high part of the resistance. The diffusion of the coolant (I) braked in the lower part allows obtaining a temperature higher than that heated by the upper part of the resistor (j), so as to continue to diffuse significant heat in the coolant once the thermostatic probe (m) cutting off the power supply.
