Description

CALENTADOR DE FLUIDOS    FLUID HEATER

La presente invención se refiere a un calentador de fluidos, más concretamente a un calentador de fluidos donde se aprovechan las pérdidas energéticas de las The present invention relates to a fluid heater, more specifically to a fluid heater where the energy losses of the

5 corrientes de Foucault o corrientes parásitas en forma de calor (efecto Joule), por ejemplo para calentar agua, con el fin de obtener agua caliente en una instalación doméstica de agua sanitaria o bien para obtener un fluido caliente para su aplicación a nivel industrial. 5 eddy currents or parasitic currents in the form of heat (Joule effect), for example to heat water, in order to obtain hot water in a domestic sanitary water installation or to obtain a hot fluid for industrial application.

Las corrientes de Foucault se producen cuando u n conductor atraviesa un campo Foucault currents occur when a conductor crosses a field

10 magnético variable o viceversa. El movimiento relativo causa una circulación de electrones o corriente inducida dentro del conductor. Estas corrientes circulares de Foucault crean electroimanes con campos magnéticos que se oponen al efecto del campo magnético aplicado. Cuanto más fuerte es el campo magnético aplicado, o mayor la conductividad del conductor, o mayor la velocidad relativa de 10 magnetic variable or vice versa. Relative motion causes an electron circulation or induced current within the conductor. These circular eddy currents create electromagnets with magnetic fields that oppose the effect of the applied magnetic field. The stronger the applied magnetic field, or the greater the conductivity of the conductor, or the greater the relative speed of

15 movimiento, mayores serán las corrientes de Foucault y los campos opositores generados. Las corrientes de Foucault crean pérdidas de energía debido al efecto Joule. Más concretamente, dichas corrientes transforman formas útiles de energía, como la cinética, en calor, aunque generalmente es un efecto no deseado, ya que disminuyen la eficiencia de muchos dispositivos que usan 15 movement, greater will be the currents of Foucault and the opposing fields generated. Foucault currents create energy losses due to the Joule effect. More specifically, these currents transform useful forms of energy, such as kinetics, into heat, although it is generally an unwanted effect, since they decrease the efficiency of many devices that use

20 campos magnéticos variables, como los transformadores de núcleo de hierro y los motores eléctricos. 20 variable magnetic fields, such as iron core transformers and electric motors.

La presente invención aprovecha la desventaja que supone la generación de estas corrientes de Foucault y su conversión en calor debido al efecto Joule para calentar un fluido, por ejemplo para conseguir agua caliente sanitaria, aplicando 25 un campo magnético variable que inducecorrientes de Foucault sobre un serpentín de material ferromagnético y por cuyo interior circula el fluido a calentar. The present invention takes advantage of the disadvantage of generating these eddy currents and their conversion into heat due to the Joule effect to heat a fluid, for example to obtain domestic hot water, applying a variable magnetic field that induces eddy currents on a coil of ferromagnetic material and through which the fluid to be heated circulates.

Son bien conocidos, por ejemplo, calentadores de agua eléctricosque incluyen un depósito de agua de considerable tamaño donde se mantiene almacenada agua caliente gracias a la incorporación de una resistencia eléctrica. Éstos ocupan 30 mucho espacio y, cuando la necesidad de flujo de agua caliente es elevada, no satisfacen la demanda de forma adecuada. Por otro lado, también son conocidos They are well known, for example, electric water heaters which include a water tank of considerable size where hot water is kept stored thanks to the incorporation of an electric heater. These take up a lot of space and, when the need for hot water flow is high, they do not meet the demand adequately. On the other hand, they are also known

los calentadores de agua basados en combustibles no renovables, como gas natural o propano, que, además de hacer necesaria su instalación y verificación por parte de técnicos especialistas, conlleva los riesgos conocidos asociados al combustible, tales como posibilidad de deflagración o explosión, inhalación water heaters based on non-renewable fuels, such as natural gas or propane, which, in addition to making their installation and verification by specialist technicians necessary, entail known risks associated with the fuel, such as the possibility of deflagration or explosion, inhalation

5 accidental de gases por mala combustión, etc. 5 accidental gas from bad combustion, etc.

Así el calentador de fluidos de la presente invención permite evitar las desventajas de los dispositivos convencionales conocidos del estado actual de la técnica. Thus, the fluid heater of the present invention avoids the disadvantages of conventional devices known from the current state of the art.

Para ello, el calentador aquí descrito esencialmente consta de un elemento rotor For this, the heater described here essentially consists of a rotor element

10 cilíndrico en el cual se fijan una serie de imanes permanentes y de un elemento conductor hueco dispuesto de forma no movible cercano al rotor, a modo de serpentín, rodeando dicho rotor a cierta distancia y por cuyo interior fluye el fluido a calentar impulsado por una correspondiente bomba. El rotor está adecuadamente conectado al eje de un motor que, a su vez, acciona la citada 10 cylindrical in which a series of permanent magnets and a hollow conductive element arranged in a non-movable manner close to the rotor are fixed, by way of a coil, surrounding said rotor at a certain distance and through which the fluid to be heated flows driven by a corresponding pump. The rotor is properly connected to the axis of an engine that, in turn, drives the aforementioned

15 bomba. El giro del rotor así diseñado genera un campo magnético que varía cíclicamente, de forma que el movimiento relativo entre los imanes permanentes insertos en el rotor y el elemento conductor fijo provocan un campo magnético variable, produciéndose corrientes de Foucault en este último, las cuales, por efecto Joule, provocan el calentamiento del elemento conductor o serpentín 15 bomb The rotation of the rotor thus designed generates a magnetic field that varies cyclically, so that the relative movement between the permanent magnets inserted in the rotor and the fixed conductor element causes a variable magnetic field, producing eddy currents in the latter, which, by Joule effect, they cause heating of the conductive element or coil

20 ferromagnético y, con ello, del fluido que circula por su interior. La transmisión del calor del serpentín sobre el flu ido que circula por el mismo se produceentonces por contacto directo, de manera que la temperatura que se puede alcanzar variará en función de diferentesparámetros, tales como el número y la disposición particular de los imanes en el rotor, su tamaño, su longitud en correspondencia 20 ferromagnetic and, with it, the fluid that circulates inside. The heat transfer of the coil over the fluid flowing through it then occurs by direct contact, so that the temperature that can be reached will vary depending on different parameters, such as the number and the particular arrangement of the magnets in the rotor , its size, its length in correspondence

25 con la longitud del serpentín, etc. 25 with the length of the coil, etc.
