Abstract

SE PRESENTA UN METODO PARA CALENTAR UN LIQUIDO QUE COMPRENDE EL SUMINISTRO DE UN MANDRIL (12) EN EL INTERIOR DE UN ELEMENTO CALENTADOR (14) QUE TIENE AL MENOS UNA SUPERFICIE, Y EL PASO DEL LIQUIDO HACIA ABAJO POR EL MANDRIL EN FORMA DE UNA PELICULA FINA (22) DE MANERA QUE NO SE PONGA EN CONTACTO CON LA SUPERFICIE CALENTADORA (14). ESTO PUEDE LLEVARSE A CABO EN UN APARATO QUE COMPRENDE UN ELEMENTO CALENTADOR DENTRO DEL CUAL ESTA SITUADO UN MANDRIL (12), SIN CONTACTO CON EL ELEMENTO, UNA FUENTE DE LIQUIDO (18), Y MEDIOS (20) PARA PERMITIR QUE EL LIQUIDO DE LA FUENTE FLUYA SOBRE EL MANDRIL EN FORMA DE UNA PELICULA FINA (22). EL MANDRIL ESTARA NORMALMENTE MANTENIDO EN UNA ORIENTACION VERTICAL Y LA FUENTE DE LIQUIDO PUEDE ESTAR EN LA PARTE SUPERIOR DEL MISMO. EL LIQUIDO CORRE HACIA ABAJO COMO UN PELICULA (22) A LO LARGO DE LA SUPERFICIE DEL MANDRIL. EL MANDRIL ESTA RODEADO POR LA SUPERFICIE CALIENTE DEL ELEMENTO CALENTADOR (14) Y EL CALOR PASA PRINCIPALMENTE POR RADIACION DE CALOR A TRAVES DEL HUECO (16) ENTRE LA SUPERFICIE CALIENTE DEL ELEMENTO CALENTADOR HASTA EL LIQUIDO QUE PASA HACIA ABAJO POR EL MANDRIL. DE ESTA FORMA NO HAY CONTACTO DIRECTO ENTRE EL LIQUIDO A CALENTAR Y CUALQUIER SUPERFICIE CALENTADA DEL ELEMENTO CALENTADOR (14). EL MANDRIL MISMO NO ESTARA NORMALMENTE CALIENTE, Y PUEDE ESTAR HECHO A PARTIR DE MATERIALES QUE TENGAN BUENAS PROPIEDADES DE CORROSION PERO UNA CONDUCTIVIDAD TERMICA TAN POBRE QUE NORMALMENTE NO SE USARIAN EN LA MANUFACTURA DE UN INTERCAMBIADOR DE CALOR. NO HAY NECESIDAD DE METAL, Y POR EJEMPLO, PODRIA HACERSE A PARTIR DE MATERIALES TALES COMO MATERIALES CERAMICOS O CRISTAL, OPCIONALMENTE CON REVESTIMIENTOS DE, POR EJEMPLO, PTFE.A METHOD FOR HEATING A LIQUID COMPRISING THE SUPPLY OF A CHUCK (12) INSIDE A HEATING ELEMENT (14) THAT HAS AT LEAST ONE SURFACE, AND THE PASSAGE OF THE LIQUID DOWN THE MANDREL IN THE FORM OF A FILM IS PRESENTED. FINE (22) SO THAT IT DOES NOT CONTACT THE HEATING SURFACE (14). THIS MAY BE CARRIED OUT IN A DEVICE COMPRISING A HEATING ELEMENT WITHIN WHICH A CHUCK IS LOCATED (12), WITHOUT CONTACT WITH THE ELEMENT, A SOURCE OF LIQUID (18), AND MEANS (20) TO ALLOW THE LIQUID OF THE SOURCE FLOWS OVER THE CHUCK IN THE FORM OF A FINE FILM (22). THE CHUCK WILL NORMALLY BE MAINTAINED IN A VERTICAL ORIENTATION AND THE SOURCE OF LIQUID MAY BE ON THE TOP OF IT. THE LIQUID RUNS DOWN LIKE A FILM (22) ALONG THE SURFACE OF THE CHUCK. THE CHUCK IS SURROUNDED BY THE HOT SURFACE OF THE HEATING ELEMENT (14) AND THE HEAT PASSES MAINLY BY RADIATION OF HEAT THROUGH THE HOLE (16) BETWEEN THE HOT SURFACE OF THE HEATING ELEMENT UNTIL THE LIQUID PASSING DOWN THROUGH THE MANDRANT. IN THIS WAY THERE IS NO DIRECT CONTACT BETWEEN THE LIQUID TO BE HEATED AND ANY HEATED SURFACE OF THE HEATING ELEMENT (14). THE SINGLE CHUCK WILL NOT BE NORMALLY HOT, AND MAY BE MADE FROM MATERIALS THAT HAVE GOOD CORROSION PROPERTIES BUT SO POOR THERMAL CONDUCTIVITY THAT WOULD NOT NORMALLY BE USED IN THE MANUFACTURE OF A HEAT EXCHANGER. THERE IS NO NEED FOR METAL, AND FOR EXAMPLE, IT COULD BE MADE FROM MATERIALS SUCH AS CERAMIC OR GLASS MATERIALS, OPTIONALLY WITH COATINGS OF, FOR EXAMPLE, PTFE.
