| (54) | Modular electric radiator |
| (57) The present invention relates to a modular electric radiator comprising at least
heating means [1] and a plurality of curved -profile diffuser modules [3], as well
as a plurality of attachment bars which attach by their upper and lower parts the
different diffuser modules [3] in a tongue and groove manner, through the actual attachment
means [6], and said bars being threaded in at least their ends and fixed at said ends
by closing nuts [62].

Object of the Invention
[0001] The object of the invention is to present a new electric type radiator formed based on a series of modules attached to one another housing a plurality of resistors transverse to the different modules.
Background of the Invention
[0002] Radiators of the type set forth, in which the body is formed by at least two horizontal conduits, an upper and a lower conduit, and a series of vertical conduits running between the horizontal conduits closed at their ends are already known. This body is completed with two series of outer diffuser flanges located at both sides of the horizontal and vertical conduit assembly in a coplanar position on each side. The assembly thus formed is closed on the sides by means of respective covers housing the control elements, such as the on-off switch, thermostats, etc.
[0003] It is also known that the assembly of the body is subdivided, according to planes perpendicular to the horizontal conduits, into identical independent modules, each of which modules includes horizontal conduit sections, a vertical conduit running between the horizontal conduit sections, into which it opens, and two vertical diffuser flanges running in coincidence with the vertical conduits attached thereto. The horizontal tube sections have an inner threading in a different direction after their end sections. Consecutive modules are attached by means of intermediate bushings which are externally arranged and after their end sections threaded in a different direction, coincident with the inner threading of the horizontal tube sections, such that upon rotating these intermediate bushings in the corresponding direction they are screwed at the same time in the opposing ends of the horizontal tube sections of two consecutive modules.
[0004] In these radiators the body formed from the horizontal and vertical conduits is filled with oil or a similar thermal fluid which is heated by means of resistors installed inside the same body. This configuration demands that the closing of the ends of the horizontal conduits be airtight for the purpose of preventing leaks of the thermal fluid. In addition the weight of these radiators is relatively high since the horizontal and vertical conduit assembly is filled with oil or another similar thermal fluid. Finally it must be pointed out that the fact that the radiator is filled with oil implies an increase in the cost of the radiator.
Description of the Invention
[0005] In order to alleviate the problems mentioned above, the modular electric radiator object of the invention is presented, comprising at least:
heating means comprising at least,
a plurality of thermal metal resistors,
a plurality of curved profile diffuser modules in turn comprising,
a plurality of inner flanges,
attachment means between diffuser modules
and in which the diffuser modules are comprised between two temperature control and supply modules of the heating means, preferably located on the left and right of the assembly of the plurality of modules.[0006] As a result of this configuration, the resistors installed in the horizontal conduits of the radiator, and where applicable the additional resistors, will heat the air contained therein, there being a possibility that at least part of this air penetrates or exits through the lower outlets. The hot air contained in the radiator will directly heat the walls of the different conduits through these diffuser flanges.
[0007] The arrangement of the resistors and the heating of the air contained in the radiator allows the temperature thereof to be uniform, and the air contained to be completely dry, by the heating thereof. As has been indicated, the radiator lacks oil or another similar heating fluid, therefore its weight will be reduced and the manufacture more economical.
[0008] The connections between the different modules likewise enable an efficient and quick assembly of the radiator, resulting in a modular capacity that is evidently superior with regard to the known state of the art.
