Description

  

  Heizkörper, insbesondere aus     .Aluminium.       Die     Erfindung    betrifft einen     Heizkörper,     insbesondere     aus    Aluminium, mit grossem  Anteil an Wärmeabgabe durch     Strahlung     und besteht     darin,    dass wenigstens ein Teil  der dem Raume zugekehrten Oberfläche       anodisch    oxydiert ist. Die     anodisch    oxydierte  Oberfläche kann gegebenenfalls gefärbt sein.  



  Aluminium ist wegen seiner     Leichtigkeit,     Billigkeit und Luftbeständigkeit ein guter  Baustoff für     Wärmeaustauscher,    insbeson  dere auch für Radiatoren. Ein     Nachteil     liegt in der geringen Strahlungszahl des me  tallischen Aluminiums, deshalb werden Alu  miniumanstriche zur Herabminderung der  Sonneneinstrahlung auf Dächern     etc.    mit Er  folg verwendet.  



  Diesem Nachteil kann     nun    begegnet wer  den durch die sogenannte     anodische    Oxyda  tion der Aluminiumoberfläche, wodurch diese  eine sehr hohe Strahlungszahl erhält und  gleichzeitig noch unempfindlicher gegen  atmosphärische     Einflüsse        wird.    Nach aus  geführten Messungen kann die Strahlungs  zahl bis über     -90%    der absoluten schwarzen         1I@i     I    Strahlung gesteigert werden, wodurch     die          Leistungsfähigkeit    von     Wärmeaustauschern,     die einen grösseren Anteil der Wärme durch  Strahlung abgeben, gesteigert     wird.    Das Be  streben,

   den Strahlungsteil zu erhöhen, wird  ganz besonders im     Radiatorenbau        intensiv     verfolgt.  



  Da sich die     anodisch    oxydierte Oberfläche  auch leicht färben     lässt,    so ist     damit    gleich  zeitig ein     Mittel    an die Hand gegeben, die       weisse    Oberfläche von     Aluminium-Heizkör-          pern    mit jedem beliebigen     gewünschten    Farb  ton zu versehen, der ebenfalls sehr haltbar  ist,     weil    die     anodisch    oxydierte Aluminium  oberfläche     schwammartig    ist und     gewisse     Farben sehr     intensiv        aufsaugt.     



  Statt einem Teil der dem     Raum    zuge  kehrten Oberfläche kann auch die ganze  Oberfläche, sogar innen und aussen, des     Heiz-          körpers        anodisch        oxydiert        sein.  



  Radiators, especially made of aluminum. The invention relates to a radiator, in particular made of aluminum, with a large proportion of heat emission by radiation and consists in that at least part of the surface facing the room is anodically oxidized. The anodically oxidized surface can optionally be colored.



  Because of its lightness, cheapness and air resistance, aluminum is a good building material for heat exchangers, especially radiators. One disadvantage is the low radiation number of the metallic aluminum, which is why aluminum paints are used to reduce solar radiation on roofs, etc. with success.



  This disadvantage can now be countered by the so-called anodic oxidation of the aluminum surface, which gives it a very high radiation number and at the same time becomes even less sensitive to atmospheric influences. According to measurements carried out, the number of radiation can be increased to over -90% of the absolute black 1I @ i I radiation, which increases the efficiency of heat exchangers, which give off a larger proportion of the heat through radiation. The effort,

   Increasing the amount of radiation is being pursued intensively, especially in radiator construction.



  Since the anodically oxidized surface can also be easily colored, it also provides a means of providing the white surface of aluminum radiators with any desired color, which is also very durable because it is anodic oxidized aluminum surface is spongy and absorbs certain colors very intensively.



  Instead of part of the surface facing the room, the entire surface, even inside and outside, of the heating element can be anodically oxidized.
