Definitions
- the invention relates to a radiator according to the preamble of claim 1.
- Radiators usually have a base made of unalloyed steel and a surface coating to achieve a special colored look. Depending on the location of the radiator, different coating processes are used. For example, radiators in living areas are often powder-coated or painted, and radiators in bathrooms are also electroplated.
- a disadvantage of the solutions described above is that the surface coating has a negative influence on the thermal output of the steel radiator.
- galvanically chrome-plated steel radiators result in reduced outputs of around 20% to 30% compared to painted or powder-coated steel radiators.
- This poor heat output with chrome-plated steel radiators requires large and expensive radiators that take up a lot of space.
- the object of the present invention is to provide a radiator with a high-gloss surface similar to that of chromed radiators, which eliminates the aforementioned disadvantages and is simple and inexpensive to produce in terms of device technology.
- the radiator according to the invention has a base body made of metal, in particular aluminum.
- the surface of the base body is machined in such a way that galvanic chrome plating or gold plating to protect and to produce a high-gloss surface is not necessary.
- any other metal such as stainless steel, can also be used.
- the surface is high-gloss and has a degree of gloss of approximately 80% to 100%.
- the radiator according to the invention has a significantly better heat output than conventional chromed steel radiators.
- a conventional steel radiator with galvanic chrome plating has a 30 to 40% lower thermal output than a high-gloss radiator according to the invention
- radiator according to the invention can be designed to be significantly smaller and more cost-effective with the same heat output, which is particularly advantageous in bathrooms with mostly limited space.
- the metal base body of the radiator according to the invention is mechanically ground, mechanically polished and chemically or electrochemically polished.
- radiator according to the invention advantageously has an anodized layer to increase the corrosion resistance and to maintain the degree of gloss.
- Another embodiment provides a clear lacquer layer to increase the corrosion resistance and to maintain the degree of gloss.
- Radiators known per se with an aluminum base body are often chrome-plated to achieve a high-gloss surface, which is not only complex and expensive, but also significantly reduces the heat output.
- Figure 1 shows a perspective view of an inventive
- the radiator 2 has a base body 4 and two connections 6, 8 for connecting an inlet line for supplying water and an outlet line (not shown).
- the base body 4 has two parallel tubes 12, 14 which are spaced apart by rungs 16 arranged transversely to the tubes 12, 14. The water flows through the rungs 16 between the two tubes 12, 14, so that towels (not shown) can be hung over the rungs 16 for drying, for example.
- the base body 4 does not require a surface coating to achieve a degree of gloss, but the surface 10 of the base body 4 is machined in such a way that it increases the overall aesthetic impression of the radiator 2 and also protects the base body 4 against corrosion and damage.
- surface 10 has a gloss level of about 80% to 100%.
- a reflectometer according to DIN 67 530 is suitable as an aid for gloss assessment.
- a major advantage of the radiator 2 according to the invention is that it has an improved thermal conductivity compared to conventional chromed steel radiators.
- An example is a chrome-plated steel radiator that develops a thermal output of approximately 750 W, whereas an aluminum radiator 2 of the same size according to the invention has a thermal output of approximately 1100 W. That the radiator 2 according to the invention has an almost 50% higher heating capacity with the same size, its high thermal conductivity allowing a quick reaction to switch-on and switch-off processes, for example by room thermostat control, which noticeably reduces heating costs.
- the metal base 4 of the radiator 2 is mechanically ground, mechanically polished and chemically bwz to achieve the desired degree of gloss. electrochemically polished.
- Mechanical grinding usually begins with coarse grinding to remove large unevenness or scratches on the surface 10 by means of a grinding wheel.
- grinding is dry, the peripheral speed being in principle within a range from 420 to 1200 rpm.
- a grinding wheel or Lamella discs made of alumina with 60 to 120 mesh, cloth, sheep leather or muslin are used at 1500 to 1800 rpm.
- peripheral speeds of up to 3000 rpm are also permissible.
- the grinding is followed by the fine grinding or pre-polishing.
- grinding wheels made of felt or sheep leather or diagonally cut muslin discs with emery of 100 to 200 meshes and air cooling are used.
- the peripheral speed is approximately in the range of the process steps described above or is slightly increased.
- the surface 10 is mechanically polished with a polishing disc in order to eliminate grinding marks and to achieve a shine.
- the polishing disc has a plurality of discs, preferably made of loose or stapled cotton fabric, and rotates at about 2000 to 2600 rpm. You can choose between dry or wet polishing. In order to change the hardness of the polishing disc, in addition to changing the number of threads of the cotton fabric, cloth, wood or paper inserts can also be arranged between the individual discs.
- the surface 10 does not overheat and does not tear.
- this can be done by a suitable choice of the speed of rotation, the contact pressure of the disks, as well as by a appropriate formation of the discs or by using abrasive or polishing agents such as greases, oils or pastes.
- the surface 10 is preferably finally electrochemically anodized or anodized, so that the resistance to corrosion of the surface 10 is increased by an anodized layer. This is particularly advantageous if the radiator 2 is used in rooms with high humidity, such as bathrooms or, as mentioned above, for drying damp towels.
- the surface 10 is chemically converted, so that a porous aluminum oxide layer is formed, which is sealed in a last process step.
- the surface 10 can also be provided with a clear lacquer layer to increase the corrosion resistance instead of the anodized layer.
- the lacquer layer can be applied, for example, by spraying, in the form of a powder, using a brush or in an immersion bath.
