Description

The present invention relates to a radiator, in particular for central and / or District heating systems with at least one heat dissipation section with a heat carrier fluid, for example water, is at least partially fillable, according to the upper Concept of claim 1. Furthermore, the invention relates to a heat absorption body, especially for radiators, according to the preamble of claim 1 Claim 17.

Conventional radiators have convector inserts on the back of a heating plate or are arranged between two or more heating plates. Here the convector body often welded on. This process is regularly difficult and time-consuming also leads to major problems when coating the radiators Colour. This often leaves uncoated surfaces that rust, so this type of known plate radiator with regular quality problems and manufacturing problems brings.  

Another problem with this type of radiator is the fact that the fixed Mounting the convectors means that they become very dirty after a short time and through their extremely poor accessibility to an annoyance and an over perform moderate cleaning work. Because of these problems, a Very often completely refrain from cleaning such radiators, which in turn leads to severe hygiene problems and health problems, especially for Allergy sufferer leads.

This is where the present invention comes in by tackling the task set forth above to eliminate at least partially the listed deficiencies in the prior art. Ins in particular, it is the object of the present invention, a radiator or a To provide heat absorption body that is easier to clean.

The above object is achieved by a radiator with the in claim 1 Features listed or a heat absorption body with the in the claim 17 listed features solved. Advantageous embodiments go from the sub claims.

The advantages that can be achieved according to the invention are based on the fact that heat absorption body is reversibly arranged in a radiator, the latter in the radiant heat Convection heat is implemented. In this way, the radiant heat of the radiator used effectively in a building, particularly on the side facing away from the room become. Accordingly, the radiant heat between two heating plates one Radiator is also used to heat the room, so that the heat output of a corresponding radiator by up to 20% or even more can be increased.

The absorption body according to the invention can also be used in a conventional heating element with convector. However, the convector should be preferred be shaped that the use of a correspondingly shaped absorbent body according to a  Aspect of the invention can be used in the convection body of the radiator without the Absorbent body must have a too complicated shape. It is particularly too prefer if the convection body is designed so that it as a coherent flat plate, as a flat tile, flat tarpaulin or the like in the convection body can be used. Of course, the absorption body can also have the shape of the convex tion body in the radiator follow to an even higher amount of radiant heat to be able to convert to convection heat due to a larger area.

It is particularly important to note that convection bodies that are not closed Convection chimneys for indoor air are much more accessible than that in the prior art mostly used convection body with closed convector tion fireplaces. Here is a much easier assembly of convection bodies possible, later the, for example, ripped convection body together with the Absorbent bodies can in turn form convection chimneys.

Of course, the absorption body in the radiator according to the invention or the Absorbent body according to the invention can be reversibly provided. However is it is preferable if a specially designed mounting device is preferred reversible fixing of the absorption body on the radiator is provided. The Monta Geeinrichtung itself can also be arranged reversibly. In this way can make it possible to improve or increase the heating capacity of a radiator vary, with the absorption body according to the performance requirements can be formed or correspondingly adapted assembly facilities for the under different conceivable absorption bodies can be used. You can all advantages achievable according to the invention are retained, namely an increased one Heating power, easy manufacture of the radiator itself and good manageability speed, which includes the possibility of easy cleaning of the radiator as a whole.

The absorption body can preferably also have a surface structure that can be regular or irregular, for example. The absorption body can  in this advantageous embodiment, for example, corrugated, honeycomb-shaped, nubbed etc. be, which increases the area for the absorption of heat radiation results and at the same time the surface over which the radiant heat is increased converted to convection heat by air passing the absorption body can be delivered.

According to a further aspect of the invention, one designed as a convector can also be used here Absorbent body reversibly on a heat dissipation section, for example one Heating plate of a plate radiator, be attached or between the heat dissipation cuts, for example heating plates, are introduced, such a convection body preferably due to the material-specific inherent elasticity on or between the components of the radiator can be kept. It is also preferred here the absorption or convection body at least over vertical subregions of the assigned radiator vertically aligned channels or chimneys to the rise of channel and heat heated air.

The absorption body according to the invention can itself advantageously be designed such that that its position and / or its heat-related effectiveness can be varied. The absorption body can, among other things, be roller-blind, curtain-like, blind-like, be designed with slats or the like. Here, for example, in a climatically mild time the absorption bodies are rendered ineffective or the heat output of the radiator can be varied. Heating power could be saved be reduced, such as heating oil consumption, and on the other hand, a Ver soiling of the absorbent body can be avoided. A pleasant jet is preferred power output and the convection (= dust whirling up) is restricted. In in the event that the absorption body consists of lamellae, could be set up or a pivoting of the slats in a horizontal position also the heating power of Radiator can be reduced overall, with the horizontally placed slats in addition, the air flow through the radiator is obstructed or completely Could be brought to a standstill. Here, too, there would be an additional influence on the  Heating capacity of the radiator easily possible. Here are the expert in relation to the Formation of the absorbent body many different possibilities in the prior art known, for example from the shading technology of flow technology, etc. The here known means can in various ways also in the present field Be put into action.

In order to influence the heating capacity of the radiator, it is also sufficient if according to one advantageous embodiment of the absorption body from a flat plate, a flat Cloth or the like is made, wherein at the upper end or, if appropriate, on lower end of this plate of the absorbent body a pivotable or fold out barer section is provided, the air flow between two heating plates of the radiator pers hindered or completely prevented in this way, the heating power of the To change or specifically adjust the radiator.

The holder of the absorbent body can be made of materials that have poor heat have management. Such a holder can be designed, for example, as a clamp be the one of the absorption body on the radiator or between the heating plates Radiator clamped. It is also possible to attach to a Ver provide part of the radiator clothing, for which especially the top cover of a Radiator, for example in the form of a grill, comes into question.

Insofar as the absorption body is provided with pivotable sections, For example, pivotable sections designed as slats also around a vertical Axis can be pivoted, so that by pivoting these sections, the air flow can not be affected or influenced by the radiator, but the Heizlei Stung varies due to the absorbent body and can be regulated.

The absorption provided according to the other aspect of the present invention body is designed according to the above explanations, but can also be detached  used by the radiator itself and thus used in existing radiators are that are not designed for this absorption body from the outset.

Below is a table from which the gain in heating power can be seen is when the absorption body is used in a radiator.

In the following description of the figures, the same or at least equivalent are Components mostly provided with the same reference numerals or at least reference numbers.

In Fig. 1, the components of the radiator, preferably a plate heater, here the heating plates, are generally designated by the reference numeral 10 . In the embodiment shown in Fig. 1, two heating plates 10 are provided, between which an absorption body 12 is provided. This absorption body 12 may be in the form of a plate, a cloth, in particular a stretched cloth, a solid cardboard or the like forms. The absorption body can be colored dark or black in order to be able to absorb as much radiant heat as possible. The surface of the absorbent body can be smooth or blunt, with a surface grain or creasing which gives a blunt impression is preferred, since in this way a larger surface is made available, with the possibility of a larger amount to absorb heat radiation (see "Natural convection enhancement on micro-grooved surfaces" by Wang, Ting; Mislevy, Scott P .; Huang, John CP, published in Journal of Enhanced Heat Transfer v 1 n 3 1994. p 245-254).

Of course, the invention can also be used with other types of radiators, e.g. B. for radiators with registers made of vertical or horizontal pipes.

The absorption body 12 can be held between the heating plates 10 via cross struts 14 , which can serve as spacers. The Querver struts 14 preferably do not extend over the entire length of the radiator, but are only provided in sections. The introduction between the heating plates can be done in that the elastically flexible absorption body is bent in order to be able to sink the struts 14 between the heating plates.

In the embodiment according to FIG. 2, a panel radiator for centralized heating systems, that is to say for central heating systems or centralized heating systems based on district heating, can also be seen, in which the absorption body 12 is held by a T-shaped strut 14 , which is located at the upper end of the radiator can be inserted between the welding hubs of the heating plates 10 . Here it is also possible to continuously design the holding or mounting device formed with the cross strut 14 , in order to thereby simultaneously provide an upper cover.

If the absorbent body 12 is made, for example, of fabric, such as black felt or the like, it is advantageous if it is provided with one or more weights at the lower end so that the absorbent body cannot be moved by the rising warm air. It is advantageous if the weights are removable so that it is possible to wash the absorbent body wet, for example in a conventional washing machine.

In Fig. 3, a radiator according to a particularly simple embodiment of the inven tion is shown, where an absorption body in the form of a plate, such as a plate made of cardboard, plywood, sheet metal or the like, has been placed between two heating plates 10 of a plate heater. If necessary, the absorption body 12 can also be pulled out and cleaned here. A fixation, that is, for example, welding the absorption body 12 to the plate heating element is not necessary here.

FIGS. 4 and 5 show another embodiment of a heater with a body Absorp tion according to the invention. In this absorption body 12 a, various movable sections are provided in succession, which can be pivoted about a vertical axis. This vertical axis extends in the vertical direction of the radiator. If the individual sections of the absorption body 12 a are aligned substantially parallel to the heating plates, the absorption body can develop its optimal performance and convert the radiant heat of the heating plates 10 essentially into convection heat by transferring the heat to the room air. The radiator shown here is attached to the heating plate provided with the retaining tabs 11 on a building wall or a standing console or the like and the absorption body 12 a ensures a more effective use of the radiant heat of the heating plates 10 , which otherwise mostly dissipated with the heating medium, for example water would become and thus would not be available to the indoor climate. The rear side of the heating plate provided with the holding tabs 11 radiates onto a building surface, and for more effective use of this heat portion it may be necessary to also arrange an absorption body or convection body behind the rear heating plate 10 in order to further increase and heat the heating power of this heating element to reduce any heat leak in the building.

Here, too, the absorption body 12 a can be assembled by using the shape of the heating plates along the weld seams or hubs 10 a.

In Fig. 5, a position of the individual portions of the absorbent body 12 a is shown, in which the absorbent body 12 a only a minimal amount of radiant heat into convection heat transforms. Here, of course, it is advisable, depending on the heat requirement, to pivot the slats or sections of the absorption body 12 a. For this purpose, an adjusting device can be provided on the radiator or on the paneling of the radiator, for example an adjusting knob or the like, as can be used in conventional slats, blinds or the like.

In FIG. 6 and FIG. 7, another embodiment illustrated in accordance with the invention, which makes use of the principal layout of the absorbent body 12 a shown in FIGS. 4 and 5. Here, however, the absorption body 12 b has the additional advantage that not only the conversion coefficient of the radiant heat into convection heat can be regulated via this, but also the air flow between the heating plates 10 can also be influenced or even completely prevented. In this way, the performance of a radiator can be extremely affected. In addition, there is the possibility here of providing a particularly simple and reversible fastening for the absorption body 12 b in connection with an upper covering 16 of the radiator.

In FIGS. 8 and 9, a further advantageous embodiment is shown in which an absorption body 12 c is disposed on a rotatable shaft 18 so that this arrangement provides a roller blind which can be disposed within a heater.

FIG. 10 shows a further embodiment of an absorption body 13 d which is inserted into the convection chimneys of an existing convection body 20 with cantilevers of the absorption body 12 d assigned to them. A bracket can be accomplished detached from this type of introduction of the absorbent body 12 d.

The heat transfer from the radiation surface 10 to the absorbent body 12 is substantially determined by the surface of the radiation surface 10 . The heat transport can be increased by increasing the radiation area 10 . This can be done by means of ribs 20 or by increasing the specific surface (grain, grooves or the like). A combination of both on the radiation surface and on the absorption body is particularly advantageous.

A corresponding embodiment is shown in FIGS. 11a and 11b, which shows a formed as a flat plate, cloth or the like absorbent body 12 d, which is fitted between convection bodies 20 , which are attached to the respective heating plates of the two-plate heating element. Here, convection chimneys are formed between the convection body 20 and the heating plate 10 assigned to it. Here, the performance of the absorption body 12 d is already lower than that of the absorption body 12 d according to FIG. 10 due to its smaller area.

FIG. 12a to 12i show various types of differently shaped absorption or Konvektionskörper 12 e, which can be connected by inserting between two heating plates or behind a hot plate with a heating element, in particular a panel radiator.

The absorption or convection body 12 e to 12 h are designed so that one or more convection chimneys are formed between the heating plates and the absorption or convection body.

Only the absorption or convection body 12 i has additional closed convection chimneys 13 c, which are already easily created by the manufacture of the absorption or convection body 12 i.

The absorption or convection body 12 e to 12 h form their convection channels or chimneys over their geometry, which bears with the respective surfaces 13 b on the radiator or is jammed with it, with heat transfer to the convection body also being desired here can. The air can rise here in the convection chimneys 13 a in order to be heated. This is also possible in the embodiment according to FIG. 12e, in which case the convection chimneys 13 c in the convection body 12 e themselves additionally participate.

All of the embodiments according to FIGS . 12a to 12i have in common that they can also be held in or on the radiator via mounting devices, but can also be clamped in order at the same time to enable heat transfer from the radiator itself to the convection body.

The embodiment according to FIG. 13 shows an absorption body 12 k, which is provided with a pivotable section 24 which can be pivoted about a pivot axis 22 in such a way that the convection channel between the heating plates 10 is closed. The left-hand illustration according to FIG. 13 shows the position of the pivotable section 24 , in which the absorption body 12 k, on the one hand, has its optimal effect and, on the other hand, air can rise through the heating element, ie between the heating plates 12 , for an additional heat output to unfold. The right-hand illustration according to FIG. 13 shows an adjustment of the pivotable section 24 in that no air can rise through the heating element, so that the heating power of the heating element is greatly reduced. In both cases, the lower section of the convection body always acts 12 k, but the radiant heat converted into convection heat cannot be given off to rising air in the case shown on the right, so that the heat output of the heating body can be drastically reduced.

Referring to FIGS. 14 and 15 of the other holding devices are represented for the absorbent body 12. In both cases shown, the absorbent body 12 is fixed to the respective holding devices 26 , 28 on the upper panel 16 of the radiator with the heating plates 10 .

In the case of the embodiment according to FIG. 14, a clip-like device is seen before, between whose jaws the absorption body 12 is held. The bracket-like device 28 can be fixed by means of screws 26 in the slots of the upper cover 16 .

The embodiment according to FIG. 15 is similar to that according to FIG. 14, but with the fixing of the absorbent body on the mounting device 28 being effected by clamping the wings 28 . Subsequent assembly and removal of the absorption body 12 for later cleaning is also particularly easy here.

Of course, the attachment of the absorption or convection body according to the invention also possible in that a support on water channels with respect to the pre and The radiator returns.

It should also be noted that the convector body for plate heating elements provided according to the invention is not firmly connected to the heating plate (s) of the heating element, for example by welding or soldering, but can be held reversibly by the spring action of its own structure. The existing lamella structure of the convector, as shown in FIG. 12, is not, as is conventionally the case, perpendicular to the heating plate, but parallel to it.
