RADIATOR AND METHOD FOR MANUFACTURING IT 1 1 U ° n U

The invention relates to a radiator comprising a jacket member and a heat source therein, for example a circulating water pipe or electric resistor, which is in intimate contact with the heat-accumulating jacket member for delivering heat to it and further to room air. The invention also relates to a process for making a corresponding radiator.

10 Existing radiators for space heating are usually placed close to walls and sometimes even partially submerged. Due to the location of the installation, some of the heat radiated by the radiator goes to heat the wall, which further conducts the heat to the outside air without being useful for heating the apartment spaces in question.

3-D radiators are made of concrete and soapstone. The concrete radiator is poorly resistant to moisture and will deteriorate over time. In spite of the possible surface treatment 20, dust may also be removed from the concrete radiator. Soapstone elements have been used as heat accumulators in fireplaces. There is a pipeline in the stone where the liquid is stored. , heat and give it to the stone. Stone or stone; the liquid contained in the piping can also be heated by electrical resistors. If the fireplace is not heated, the liquid and stone will cool and the heating effect will disappear.

It is an object of the present invention to provide a new type of radiator for heating an apartment. Characteristic features of one of the preferred radiators 30 are set forth in the appended claim 1 and features of the method of manufacture of the radiator according to the invention are set forth in the appended claim 10. The radiators of the invention provide considerable advantages. As a by-product of the soapstone industry's 35 by-products, the hitherto completely untapped rock-based filler provides a new useful application. By mixing mineral filler and 110543 2 binder, the radiators used for heating can be made by casting. In addition to very good heat storage capacity, the radiator has excellent design and color variation, which also gives it interior design features. The radiator can be installed in a room to fill, for example, wasted spaces such as corners. It can also be used, for example, as a seat bench, flower stand or the like. The radiator made of mineral filler is ideally suited, for example, to humid areas, where known radiators will, over time, show corrosion or weathering depending on the material used. In principle, a radiator is eternal because it does not have the same effect. According to a preferred embodiment, the radiator also does not exhibit dust problems specific to concrete, for example, and is easily cleanable with the flat surface of the jacket portion 10. According to another embodiment, the diaper portion 10 may also be textured, providing additional interior features. In addition, the radiator must be fully recyclable, since when decommissioned it can be crushed and utilized, for example, as a filling country 20 or as a whole, for example in civil engineering.

: ·. In the following, the radiator will be described with reference to the accompanying drawings, which show some examples of radiators according to the invention. 25

Fig. 3 is a cross-sectional view of the radiator with electric resistor of Fig. 2.

· The radiator of Fig. 1 is triangular prism shaped at the ends and is heated by a circulating water. The radiator casing portion 10 is made of a mineral filler mixed with a binder material.

The heat source for the radiator is a circulating water pipeline 11, which is connected to the district heating or district heating network (not shown) by the inlet water connection 12 and the return water connection 13. The piping 11 is formed during the casting stage so that it is inserted into the mold 5 prior to the casting of the jacket portion 10.

Figure 2 shows a radiator provided with two electric resistors 14. The resistors 14 heat up the radiator casing portion 10. Power to the electrical resistors 14 is supplied through the control electronics 16 of the radiator 10, which is further connected to external electrical conductors 15. The control electronics 16 is mounted which is covered with deck 17.

15 If the electrical resistor is to be replaced, it can be mounted in a special housing that opens to the surface of the radiator. Another possibility is to detach the radiator from two parts between which a resistor is inserted. 1

The radiators of Figures 1 and 2 are manufactured by: • 7 pouring a mixture of mineral filler and binder into a casting mold pre-set prior to mass calculation. ,: either the circulation pipe 11, the electrical resistor 14 or both as the heat source. The mold may be of almost arbitrary shape; 25 which gives it a wide range of geometric shapes. When ·. the mixture formed by the sheath portion 10 is lowered into the mold by applying a compressive pressure to bring the mixture of the heat-storing sheath portion 10 into intense heat-releasing contact around the heat sources 11, 14 and further to room air. If necessary, the mold is heated to the requirements of the binder. Once the mixture has been pressed for a suitable time, it is allowed to 7. dry and cure before removing the radiator from the mold. Now, finishing surface treatment operations, such as grinding, can be performed on the jacket member 10, such as abrasions 12, 13 for recirculating water or the like or for conducting electricity to resistors 14.

The compression of the mold can also be achieved under reduced pressure. Often even a slight compression is sufficient.

After casting, keep the radiator in the oven to degass the harmful substances. The heat treatment improves the strength properties of the radiator.

It is essential for the invention that the radiator sheath portion 10 is formed of a rock-based filler which can be cured with the binder in its desired shape. For example, crushed residues from the soapstone industry, which generally have a diameter of 0-8 mm and an amount of 63 to 85% by weight of the sheath portion, may be used as the rocky filler. There has been no rational utilization of the crushed residue, which is why it is in huge quantities in the quarries of quarries and similar refineries. As a binder, for example, a polymeric resin can be used which accounts for 10 to 25%, more preferably 12 to 15% by weight of the diaper portion 10. Other types of binder and rock-like material, such as crushed glass, may also be used in the manufacture of the radiator 20 casing member 10. The color of the diaper portion 10 is obtained by: adding the desired dye to the diaper portion 10:; to the mixture. When used as a heat source, the circulating water piping 11 may be, for example, copper, plastic or otherwise, preferably; ; stainless and easily bendable material. Particularly: 25 known as an advance over the flow-through heating system, which is known to be water-cooled, is that, for example, district heating or district heating water can be connected to the radiator to continuously supply new heat to the diaper portion 10 and thus not cool down. fireplace as a heat source technology.

• · The electrical resistors 14 and the circulation piping 11 may be alternative heat sources, or both may be in the same radiator. In this case, the water, 35 oil or other suitable liquid in the circulating piping 11 is heated indirectly by an electric resistor 14 mounted on the radiator to heat the jacket member 10 or alternatively directly. Alternatively, the heat source may also be located on or in recesses such as grooves in the surface of the sheath portion 10.

Both the piping 11 and the electrical resistors 14 may also travel along different paths than those shown in the examples of Figures 1 and 2. According to one embodiment, an insulating material (not shown) may also be fitted to the radiator on the surface of the sheath portion 10, for example, facing the wall. The purpose of the insulating material 10 is to prevent the radiation of heat into a heat-absorbing wall structure, for example stone, concrete or the like. According to another embodiment, the dielectric can be used to control the heat transfer rate of the radiator. This is to insulate the jacket portion 10 from all sides. The fully insulated radiator may be provided with means for transferring heating power to the environment by means of an airflow means (not shown), including a fan and a control device preferably operated by an airflow size control flap. The heating power of the radiator is controlled by the fan rotation speed and the airflow 20 by controlling the flap position.
