Description
Radiador con módulos de plástico.Radiator with plastic modules.
La presente invención tiene por objeto un radiador con módulos de plástico de entre los radiadores que incorporan elementos resistivos debidamente protegidos en cada uno de los módulos que componen el conjunto del radiador.The present invention aims at a radiator with plastic modules between the radiators that incorporate properly protected resistive elements in each of the modules that make up the radiator assembly.
Caracteriza a la presente invención el hecho de construir un radiador que está conformado por una serie de módulos enlazables entre sí, donde cada uno de los módulos presenta una carcasa exterior realizada en material plástico, de características tales que soporte las temperaturas para las cuales está diseñado.Characterizes the present invention the fact build a radiator that is made up of a series of modules linkable to each other, where each of the modules presents a outer shell made of plastic material, features such that it supports the temperatures for which it is designed.
Igualmente es objeto de la presente invención la disposición interior de los elementos resistivos y los materiales empleados para la transmisión de calor, siendo necesario una especial configuración y diseño del propio módulo para que la transmisión de calor tenga por medio de convección libre.Likewise, the object of the present invention is the interior arrangement of resistive elements and materials used for heat transmission, requiring a special configuration and design of the module itself so that the heat transmission have by means of free convection.
Por lo tanto la presente invención se circunscribe dentro del ámbito de los medios empleados en la difusión del calor, como elementos radiadores y de modo más particular de entre los módulos fabricados con materiales plásticos.Therefore the present invention is circumscribes within the scope of the means used in the heat diffusion, as radiator elements and more particular among the modules manufactured with materials plastics
Los radiadores eléctricos secos, es decir los que incorporan una resistencia eléctrica son bastante conocidos y utilizados y han sustituido a los de fluido térmico, resolviendo el problema de la inercia térmica planteado por los mismos.Dry electric radiators, that is the that incorporate an electrical resistor are quite known and used and have replaced those of thermal fluid, solving the problem of thermal inertia posed by them.
Ejemplos de dichos radiadores eléctricos secos los podemos encontrar descritos en las patentes de número de solicitud ES 200100537 y en la Adición a la anterior patente, contando la adición con un número de solicitud 200201517.Examples of such dry electric radiators we can find them described in the number patents of ES application 200100537 and in the Addendum to the previous patent, counting the addition with an application number 200201517.
Estos radiadores eléctricos secos cuentan con una serie de módulos unidos entre sí, donde en la cavidad interior de cada uno de los módulos se aloja una resistencia eléctrica quedando conexionados dichas resistencias por su parte inferior mediante unas regletas de conexión o espadines que se conectan a dicha regletas.These dry electric radiators feature a series of modules linked together, where in the inner cavity an electrical resistor is housed in each of the modules said resistors being connected at the bottom by means of connecting strips or sprats that connect to said strips.
Estos radiadores basan la difusión del calor en
el empleo de una serie de aletas con las que cuentan cada uno de
los módulos que componen el mismo, sin embargo la transmisión
aunque por convección no es la más efectiva posible y rápida
posible, ya que está limitada por la inercia térmica del material
con el que se ha construido cada módulo del radiador. Además el
costo y el tiempo empleado en la fabricación de cada uno de los
módulos anteriores es muy
elevado.These radiators base the diffusion of heat on the use of a series of fins with which each of the modules that comprise it have, however the transmission although by convection is not as effective as possible and quick as possible, since it is limited by the thermal inertia of the material with which each radiator module has been built. In addition, the cost and time spent in manufacturing each of the previous modules is very
high.
También sucede que los radiadores eléctricos que emplean como elemento transmisor del calor, elementos líquidos como agua o aceite, a parte de presentar problemas con las fugas y pérdidas de los radiadores, cuentan con un poder calorífico bastante bajo, por lo que una vez apagados, no retienen el calor apenas tiempo.It also happens that electric radiators that they use liquid elements as heat transmitting element as water or oil, apart from presenting problems with leaks and radiator losses, have a calorific value quite low, so once turned off, they do not retain heat barely time.
Por lo tanto, el objetivo de la presente invención, es el desarrollo de un radiador compuesto por una serie de módulos conceptualmente diferente de lo empleado hasta ahora, que supere los inconvenientes planteados cómo: las pérdidas por empleo de transmisores de calor líquidos, el elevado costo del material empleado en la construcción de cada uno de los módulos, y la forma en la transmisión de calor basada en las aletas de los módulos.Therefore, the objective of this invention, is the development of a radiator composed of a series of modules conceptually different from what has been used so far, that overcomes the problems raised as: losses by use of liquid heat transmitters, the high cost of material used in the construction of each of the modules, and the way in the heat transmission based on the fins of the modules
La invención propuesta de radiador con módulos de plástico, básicamente consiste en un radiador que está compuesto de varios módulos, donde cada uno de ellos ha sido realizado en un material plástico tal que aguante las temperaturas que el conjunto pueda alcanzar.The proposed invention of radiator with modules plastic, basically consists of a radiator that is composed of several modules, where each one of them has been made of a plastic material such that it withstands temperatures that the whole can reach.
En el interior del módulo plástico se disponen el elemento encargo de calefactar que es una resistencia eléctrica embebida dentro de cemento refractario. Las ventajas de emplear cemento refractario son varias, por una lado estructural, y por otro de inercia térmica, ya que retine mejor el calor así como que presenta una mejor conducción.Inside the plastic module are arranged the custom heating element which is an electrical resistance embedded inside refractory cement. The advantages of employing Refractory cement are several, on the one hand structural, and by another one of thermal inertia, since it retains the heat better as well as It presents a better driving.
El conjunto formado por la resistencia eléctrica embebida dentro del cemento refractario no ocupa todo el espacio interior de los módulos, sino que deja un espacio entre la cara interior del módulo plástico y el cemento refractario, por lo que se produce un calentamiento del fluido, en este caso aire, que inmediatamente rodea al mismo.The set formed by the electrical resistance embedded inside the refractory cement does not take up all the space inside the modules, but leaves a space between the face inside the plastic module and refractory cement, so there is a heating of the fluid, in this case air, which immediately surrounds it.
Por otro lado cada uno de los módulos presenta una rejilla tanto en su parte inferior como en la superior, rejillas las cuales facilitan la libre circulación del aire, entrando por la rejilla interior recorriendo todo el espacio interior y saliendo por la superior. Por lo tanto, se ha conseguido de una forma natural una transmisión del calor por convección natural sin necesidad de que sea forzada, además la transmisión térmica no se realiza por conducción directamente por contacto de partes calientes unas con otras, sino que gracias a la corriente de aire natural originada, el calor interior es transmitido por convección al exterior, empleando el movimiento del aire que tiene lugar por la diferencia de densidades originadas a su vez por la diferencia de temperaturas.On the other hand each of the modules presents a grid both in its lower and upper part, grilles which facilitate the free circulation of air, entering the interior grid through the entire space inside and out the top. Therefore, it has been achieved in a natural way a convection heat transmission natural without the need for it to be forced, besides the transmission thermal is not performed by conduction directly by contact of hot parts with each other, but thanks to the current of natural air originated, the interior heat is transmitted by outside convection, using the movement of the air that has place due to the difference in densities originated in turn by the temperature difference
Los módulos presentan su parte superior semiacodada, con el objeto de que el aire en su camino hacia el exterior no interfiera con el módulo inmediatamente adyacente. Inferiormente todos los módulos que componen el conjunto del radiador quedan unidos en su extremo inferior conformando un conjunto único de conexión eléctrica al exterior también única.The modules present their upper part semi-coded, in order that the air on its way to the exterior does not interfere with the immediately adjacent module. At the bottom all the modules that make up the whole radiator are joined at its lower end forming a unique set of electrical connection to the exterior also unique.
