Description

The invention relates to a guide profile for convectors, as well as equipped with at least one guide profile convector, which is preferably used in a central heating system, the connection to the supply and return lines of the heating system is compact or in valve design.

Convectors are radiators consisting of heating tubes with threaded lamellae, the so-called heat registers, which are provided with a function essential for the cladding, the convectors resting on suitable carrying devices and / or consoles. The cladding should largely reduce the heat emission by radiation, but almost exclusively promote the heat transfer by convection. The heating tubes themselves have different lengths and cross-sectional shapes. The lamellae threaded close together to increase the external heating surface and increase the heat transfer are fastened either mechanically or by galvanizing. Basically, a distinction is made in convectors between those with natural (static convectors) and those with forced circulation (fan convectors). Various connection variants are possible for connecting the convectors with heat registers to the connection lines of a heating system for central and / or district heating. This also depends on whether it is a connection with valve design or a standard compact connection. The convectors rest, as already mentioned on more or less suitable carrying devices or consoles and are usually attached to the panel of the convectors with these. During assembly and piping, tension and twisting of the heat register may occur. Especially with larger pipe lengths, the risk of instability of the convectors increases. Another disadvantage of the known clad radiator is that when heating and cooling of the radiator due to the rigid attachment tensions occur, which leads to unwanted noise being able to lead.

From the DE 298 09 012 U1 a guide profile for a radiator is known, which is also suitable for a convector heater and in the case of use of a convector heater with its heating coil (not shown) and the cover is in detachable connection and is arranged on at least one side of the radiator, wherein the Profile is bent at right angles and with the vertical side of the heater is attachable and wherein on this side facing the heater side of the profile provided openings for receiving connection pipes and a horizontally bent away at right angles from the heating coil side with an opening.

From this teaching, the subject of the present invention differs in that the horizontally bent away at right angles from the heater side of the guide profile has openings for receiving connection pipes and / or trimmings.

From the DE 198 08 466 A1 a guide profile for a convection heater is known, which is in detachable connection with the heating coil of the convection heater and the cover and is arranged on at least one side of the radiator, wherein the profile is bent at right angles and can be attached with the vertical side of the heater and wherein a horizontal part has an opening for receiving connecting pipes and / or trimmings, from which the subject matter of the present invention differs in that openings are provided for receiving connection pipes on this side of the profile which is sent to the heating register.

Based on this problem, the invention has for its object to improve the elements used to attach the panel to a convector to the extent that tensions and twisting of the heat register during assembly and the piping can be largely prevented. In addition, the stresses occurring during heating and cooling of the radiator due to the rigid attachment, which can lead to unwanted noise developments, should be avoided.

This object is achieved in that the convector heater is equipped with a guide profile which communicates with the heating coil of the convector heater and the cover in detachable connection and is arranged on at least one side of the radiator, wherein the profile is bent at right angles and with the vertical side can be attached to the heater. On this side facing the heating of the profile openings for receiving the heating tubes are provided, wherein the horizontally bent away at right angles from the heating coil side has openings for receiving connection pipes and / or trimmings. It is advantageous that the horizontally bent away at right angles from the heating coil side is T-shaped. This is an optimal use of materials and good access to the clothing of the radiator connected.

The profile according to the invention is outstandingly suitable for guiding and preventing rotation of the heating tubes of the convector. Furthermore, assembly forces (torques) can be taken particularly advantageous. The profile is used to connect the heat exchanger to the panel and provides a compact prefabricated unit that allows for short assembly times. The profile also serves to stabilize the entire radiator. In a further embodiment of the invention, it is advantageous that the guide profile between the panel and the heater and / or the profile and at least one heating tube of the Heating register is provided with at least one thermal expansion element, in particular a sliding element or a sliding clip.

For this purpose, the sliding element has a slot-shaped recess and a latching means for adaptation to the panel or the heating register. The sliding clip is for this purpose provided with a recess for the latch-shaped recording of the heating pipes. Thus, the tension occurring during heating and cooling of the radiator due to the rigid attachment, which lead to undesirable noise developments, can be largely avoided.

The scope of the invention also includes a convector heater with a heating coil and a surrounding the heating coil panel, which is equipped with at least one guide profile according to one of the above features and is thus equipped with all the advantages of the invention outlined above.
