DESCRIPCIONDESCRIPTION

Difusor modular de calorModular heat diffuser

Objeto de la invencionObject of the invention

La presente invencion se refiere a un difusor modular de calor ensamblable a varios difusores termicos y a una resistencia electrica para formar un radiador de calor seco para conectarse a una fuente de alimentacion de energla electrica.The present invention relates to a modular heat diffuser assemblable to various thermal diffusers and to an electrical resistance to form a dry heat radiator for connection to a power source of electrical power.

Estado de la tecnicaState of the art

Actualmente se conoce un radiador de calor seco que esta conectado a una fuente de alimentacion de energla electrica y que se fija a una pared de una habitation para calentar la misma.A dry heat radiator is currently known which is connected to a power source of electrical power and which is fixed to a wall of a room to heat it.

El radiador de calor esta formado por una pluralidad de modulos difusores de calor de configuration alargada y realizados normalmente en materiales de alta conductividad tal como el aluminio.The heat radiator is formed by a plurality of elongated heat diffuser modules normally made of high conductivity materials such as aluminum.

El difusor de calor presenta una forma de section transversal tipo H que comprende una aleta frontal y una aleta trasera unidas por una aleta central de union dispuesta perpendicularmente a las dos anteriores.The heat diffuser has a cross-sectional shape type H comprising a front flap and a rear flap joined by a central connecting flap disposed perpendicular to the two previous ones.

Los difusores tienen orificios pasantes en una o varias zonas de la aleta central para el paso de elementos de conexion entre ellos, los cuales se pueden materializar en barras que atraviesan todos los modulos y se conectan entre si, disponiendose de elementos extremos en las barras para la union solidaria de los referidos difusores modulares.The diffusers have through holes in one or several zones of the central fin for the passage of connection elements between them, which can be materialized in bars that go through all the modules and are connected to each other, with end elements available in the bars for the solidary union of the referred modular diffusers.

Ademas, los mencionados difusores son atravesados por al menos una resistencia electrica que, gracias a la corriente electrica que pasa a traves de estas, se calienta transmitiendo por contacto directo el calor a los citados difusores.In addition, said diffusers are crossed by at least one electrical resistance which, thanks to the electric current passing through them, is heated by transmitting by direct contact the heat to said diffusers.

En este tipo de radiadores, dada la naturaleza metalica de los difusores, el calor generado por la resistencia electrica se transmite a los difusores metalicos por conduction y por conveccion y radiacion al ambiente. La entrega de calor al medio ambiente por parte de los difusores se produce de manera rapida en el tiempo.In this type of radiators, given the metal nature of the diffusers, the heat generated by the electrical resistance is transmitted to the metal diffusers by conduction and by convection and radiation to the environment. The delivery of heat to the environment by diffusers occurs quickly over time.

El aire caliente asciende por el fenomeno de convection y, a su vez, transporta partlculas de polvo calientes tambien que, con el paso del tiempo, terminan ensuciando la pared a la cual esta fijado el radiador de calor. La experiencia del usuario esta, por lo tanto, deteriorada. The hot air rises due to the convection phenomenon and, in turn, transports hot dust particles that, over time, end up fouling the wall to which the heat radiator is fixed. The user experience is, therefore, deteriorated.

Para aumentar la superficie de contacto entre el difusor de calor y el aire circundante; es decir, para lograr una transmision de calor aun mayor, el difusor se completa con aletas externas continuas paralelas a la aleta frontal y trasera y dispuestas perpendicularmente a ambos lados de la aleta central, de forma que tambien aumenta la cantidad de partlculas de polvo en suspension calentadas.To increase the contact surface between the heat diffuser and the surrounding air; that is, to achieve even greater heat transmission, the diffuser is completed with continuous external fins parallel to the front and rear fins and arranged perpendicularly to both sides of the central fin, so that the amount of powder particles in the fin is also increased. heated suspension.

La superficie interior de los conductos horizontales superior e inferior en dicha estructura esta revestida con una capa de material anticorrosivo depositada sobre ellos despues de fundir la estructura.Document EP 1 935 535 describes a modular element for the composition of heating radiators comprising an aluminum structure with die-cast fins, defining one, two or more vertical ducts extending between two horizontal conduits for the passage of water ; that is, one upper and one lower, in which, in the vertical duct, a tubular insert is disposed of a metal with a greater mechanical and chemical resistance to corrosion than the material forming the finned structure. The inner surface of the upper and lower horizontal conduits in said structure is coated with a layer of anticorrosive material deposited on them after melting the structure.

Otro aspecto mas del difusor modular de calor seco es aumentar la transmision de calor al ambiente modificando la geometrla de algunas aletas que forman el difusor modular de calor seco, mientras que disminuye la transmision de calor a las partlculas de polvo en suspension en el ambiente, sin que sea necesario aumentar la potencia de una unidad o unidades de calentamiento electrico que generan energla termica, comprendidas en el radiador de calor seco.Another aspect of the modular dry heat diffuser is to increase the transmission of heat to the environment by modifying the geometry of some fins that form the modular dry heat diffuser, while decreasing the transmission of heat to particles of dust in suspension in the environment, without it being necessary to increase the power of an electric heating unit or units that generate thermal energy, included in the dry heat radiator.

El aumento de la capacidad de transmision de calor del difusor modular de calor seco se logra mediante la modificacion de la aleta frontal, trasera y las aletas externas dispuestas perpendicularmente a ambos lados de la aleta central logrando, en lugar de adoptar una forma plana, en este caso, la forma de superficies onduladas, quebrada y/o mixta, lo que aporta un considerable aumento de la superficie radiante del difusor de calor.The increase of the heat transfer capacity of the modular dry heat diffuser is achieved by modifying the front, rear and external fins arranged perpendicularly to both sides of the central fin, achieving, instead of adopting a flat shape, in in this case, the shape of wavy, broken and / or mixed surfaces, which brings a considerable increase in the radiant surface of the heat diffuser.

DescripcionDescription

La figura 1 ilustra un difusor modular de calor seco 11 que, por convection y radiation, calienta el aire que lo rodea. El difusor modular de calor seco 11 comprende una aleta frontal 12 y una aleta trasera 13 dispuestas en paralelo y conectadas por una aleta de union central 17 dispuesta perpendicularmente a las dos anteriores en una forma de seccion transversal de tipo H.Figure 1 illustrates a modular dry heat diffuser 11 that, by convection and radiation, heats the surrounding air. The modular dry heat diffuser 11 comprises a front flap 12 and a rear flap 13 arranged in parallel and connected by a central connecting flap 17 arranged perpendicularly to the two above in a cross-sectional shape of type H.

Ademas, el difusor de calor 11 comprende aletas externas 15 dispuestas perpendicularmente a ambos lados de la aleta central 17. La aleta externa 15 adopta una forma de seccion quebrada comprendiendo un conjunto de segmentos de aleta externos discontinuos de perfil ondulado, quebrado y rectillneo dispuestos cada segmento de aleta externa 15 a una predeterminada distancia de ambas aletas frontal 12 y trasera 13.In addition, the heat diffuser 11 comprises external fins 15 arranged perpendicularly to both sides of the central fin 17. The outer fin 15 assumes a broken section shape comprising a set of discontinuous external fin segments of corrugated, broken and rectilinear profile arranged each outer fin segment 15 at a predetermined distance from both front 12 and rear fins 13.

Con referencia ahora a la figura 2, un conjunto de difusores modulares de calor seco 11 se ensambla para formar un radiador electrico modular 21, del tipo de los denominados de calor seco; es decir, que no contiene aceite u otro fluido de transferencia de calor. Este radiador tiene una o mas carcasas para ubicar una unidad de generation de calor 14 del tipo de resistencia electrica21. Referring now to Figure 2, a set of dry heat modular diffusers 11 is assembled to form a modular electric radiator 21, of the so-called dry heat type; that is, it does not contain oil or other heat transfer fluid. This radiator has one or more housings for locating a heat generation unit 14 of the electrical resistance type21.

El radiador de calor seco 21 generalmente es fijado a una pared de una habitation por medios mecanicos de sujecion y anclaje 16 que sujetan el radiador de calor 21 a una distancia predeterminada.The dry heat radiator 21 is generally fixed to a wall of a room by mechanical fastening and anchoring means 16 which hold the heat radiator 21 at a predetermined distance.

La aleta frontal 12 adopta una forma de section ondulada de manera que la sucesion de ondulaciones, es decir, la sucesion continua de valles y crestas estan dispuestas horizontalmente y, ademas, el borde superior de la aleta frontal 12 termina en una pendiente oblicua hacia arriba, que representa la transition entre un valle y una cresta de la superficie ondulada, de modo que una corriente de aire que se eleva a lo largo de la superficie exterior de la aleta frontal 12 del difusor de calor 11 se dirija alejandose de la pared.The front flap 12 assumes a corrugated section shape so that the succession of undulations, ie the continuous succession of valleys and ridges are arranged horizontally and, furthermore, the upper edge of the front flap 12 ends up an oblique slope upwards. , which represents the transition between a valley and a crest of the undulated surface, so that a stream of air rising along the outer surface of the front fin 12 of the heat diffuser 11 is directed away from the wall.

La aleta trasera 13 tiene una forma de seccion transversal de tipo J invertida y una superficie radiante inferior a la superficie radiante de la aleta frontal 12 para reducir la transferencia de calor radiante hacia la superficie de la pared. Por lo tanto, el extremo superior de la aleta trasera 13 tiene una seccion oblicua ascendente que dirige una corriente de aire ascendente lejos de la paredThe rear flap 13 has an inverted type J cross sectional shape and a radiant surface lower than the radiant surface of the front flap 12 to reduce the transfer of radiant heat to the surface of the wall. Therefore, the upper end of the rear flap 13 has an upward oblique section directing an upward air current away from the wall

La aleta externa discontinua 15 presenta una configuration mixta que combina segmentos rectillneos y ondulados en forma de seccion transversal tipo S. Las posibles opciones de la aleta externa 15 en relation con la geometrla de la misma son funcion del numero de resistencias electricas 14 incluidas en el radiador de calor seco 21.The discontinuous external fin 15 has a mixed configuration that combines straight and corrugated segments in the form of a S-type cross section. The possible options of the external fin 15 in relation to the geometry thereof are a function of the number of electrical resistances 14 included in the dry heat radiator 21.

En un escenario donde el radiador de calor 21 incluye dos resistencias electricas 14, en donde una primera resistencia esta dispuesta en zona proxima al borde inferior del radiador 21 y una segunda resistencia esta dispuesta en una zona proxima al borde superior del radiador 21; la geometrla de la aleta externa 15 es tal que el aire que es calentado por la resistencia inferior es dirigido hacia el extremo de salida superior de un callejon o canal definido principalmente por las aletas frontal 12, trasera 13 y central 17 de union, y desvla esta corriente de aire caliente lejos de la resistencia superior con el objeto de evitar que esta ultima resistencia vuelva a calentar esta corriente de aire y, a su vez, recaliente las partlculas de polvo que tambien transporta.In a scenario where the heat radiator 21 includes two electric resistances 14, wherein a first resistance is arranged in an area close to the lower edge of the radiator 21 and a second resistance is arranged in an area near the upper edge of the radiator 21; the geometry of the outer fin 15 is such that the air that is heated by the lower resistor is directed towards the upper exit end of an alley or channel defined primarily by the front, 12 rear, 13 and central 17 flanges, and bypasses this hot air stream away from the upper resistance in order to prevent this last resistance from heating this air current again and, in turn, reheating the dust particles that it also transports.

Se ha de observar que la resistencia inferior y superior delimitan una cresta de la superficie ondulada de la aleta frontal 12 para definir la geometrla de un canal para el paso de la corriente de aire calentada por la resistencia inferior.It should be noted that the lower and upper resistance delimit a crest of the corrugated surface of the front flap 12 to define the geometry of a channel for the passage of the air stream heated by the lower resistance.

Tambien se observa en la figura 1, que el extremo inferior del callejon esta dividido en dos secciones de canal por un segmento en una forma de seccion transversal de tipo J girada o rotada hacia la derecha de la aleta externa 15 con el objeto de dividir la corriente de aire frlo que entra por dicho extremo inferior, dirigiendo una parte de la corriente de aire a la resistencia inferior y otra parte de la corriente de aire a la resistencia superior.It is also seen in Figure 1 that the lower end of the alley is divided into two channel sections by a segment in a cross-sectional shape of type J rotated or rotated to the right of the outer fin 15 in order to divide the cold air stream which enters through said lower end, directing a part of the air stream to the lower resistance and another part of the air flow to the upper resistance.

La aleta externa 15 mantiene las dos corrientes de aire separadas a lo largo del callejon del difusor de calor. Dicha separacion es mantenida tambien en el extremo de salida del callejon mediante un segmento rectillneo de la aleta externa 15 dispuesto a partir de la resistencia superior y que finaliza en la proximidad del extremo del callejon. Desde alll, sin contacto, la aleta externa 15 comprende un paralelogramo 16 oblicuo, cuya inclinacion es funcion de la inclinacion del extremo superior de la aleta frontal 12 y trasera 13.The outer fin 15 keeps the two air streams separated along the alley of the heat diffuser. Said separation is also maintained at the exit end of the alley by a rectilinear segment of the outer fin 15 disposed from the upper resistance and ending in the vicinity of the end of the alley. From there, without contact, the outer fin 15 comprises an oblique parallelogram 16, whose inclination is a function of the inclination of the upper end of the front flap 12 and rear 13.

Resumiendo, la geometrla del conjunto de segmentos discontinuos de aleta externa 15 esta configurada para dividir una corriente de aire en dos corrientes y para dirigir las dos corrientes e aire caliente, calentadas cada una de ellas por una resistencia electrica comprendidas dentro del difusor de calor 11, en su desplazamiento vertical ascendente, debido al fenomeno de conveccion, alejando estas corrientes de aire caliente de la pared a la se fija el radiador de calor seco 21. To summarize, the geometry of the set of discontinuous segments of external fin 15 is configured to divide an air stream into two currents and to direct the two hot air currents, each heated by an electrical resistance comprised within the heat diffuser. , in its ascending vertical displacement, due to the convection phenomenon, moving these hot air currents away from the wall to which the dry heat radiator is fixed 21.
