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.
