Description

The The invention relates to a fixed or portable tans for rooms after the The preamble of claim 1. The tubular heater has a plurality of Radiation tubes arranged in one or more rows are connected and interconnected by at least two transverse tubes are.

In such an off CH 365 849 known tubular heaters, the radiation tubes consist of double-walled tubes, which form an inner flow channel for air.

Out DE 44 09 767 A1 a tubular heater is known, the radiation tubes having a depression in the longitudinal direction to form two chambers in the tubular body for flow and return, which can flow through the space formed by the indentation air.

It are generally tubular heaters known, consisting of a plurality of small diameter tubes exist and arranged side by side in one or more rows are and are associated with common brackets that are normally consist of an upper cross tube and a lower cross tube. These Lower and upper cross tubes also function as collectors to the Circulating the heated water that is inside the individual radiation tubes flows.

These radiator can stationary be attached to the wall of the room to be heated, or you can be transportable and mounted on a movable base become.

Of Further can the radiators Have radiant tubes arranged vertically or horizontally are, straight or curved and executed in different colors, for special aesthetic Forms in relation to the space and the way of use.

For special Facilities, for example for a bathroom or a kitchen, are provided spaced apart pipe groups to toiletry towels, towels, etc. put on and preheat to can.

These tans See the use of side-by-side radiant tubes small diameter and round shape.

Of the Invention is based on the object to optimize the efficiency and a stronger one Heating the room at the same temperature and with a smaller one Allow the amount of circulating water.

at a tubular heater of the type mentioned, this task is characterized by the characterizing Characteristics of claim 1 solved.

preferred Embodiments of the invention are specified in the dependent claims.

Of the advantage obtainable by the invention is, in particular, that at the same temperature of the circulating water, the heating power is maximized.

One Another advantage of the invention is that the amount of Circulating water is reduced at the same heating effect, thereby achieved a saving in terms of consumption in the boiler can be.

Of the tans according to the invention like a conventional one Construction a number of rows of tubes arranged side by side are and are connected to a lower and an upper cross tube, who as a collector for the Circulating water act.

each Radiation tube has a substantially with a circular edge provided shape, an outer, incomplete and closed ring at the ends where the heated water circulates, and a central, both at the ends and at the sides open Section where air circulates.

These Shape is achieved by a single tube, which is suitable bent inwards.

The Farm of the resulting tube ensures a larger radiant area and therefore a higher one radiation capacity every single radiant tube.

There a continuous, internal chamber is present, the circulation favors a flow of air, which is performed as a result of a chimney effect from bottom to top and on top of the radiator exit. It is through contact with the inner wall of the water circulation ring heated so the heating effect of the radiator even increased becomes.

Of Further, the amount of circulating water and therefore the consumption in the boiler very much diminished, since the water only in the outer ring of each Radiation tube flows.

This outer ring is welded at the ends and is closed by it.

According to one Variant, each radiant tube is closed at the top by a socket having a hole with the continuous inner Chamber matches, through which the air flows, and with this jack can also special aesthetic and a personal one Rating solutions for the radiator according to the invention be brought about.

Of the tans according to the invention can be of fixed or movable type and it can be any desired number have juxtaposed tubes which are vertical or horizontal are arranged, straight or curved and in groups close to each other lie or are spaced.

embodiments The invention will be explained in more detail with reference to the drawing. In the drawing shows:

1 in a perspective view of the tubular heater;

2 the radiator of 1 in cross-section;

3 an enlarged detail of 2 ;

4 in perspective, a variant of 1 ;

5 in cross section a variant of 2 ,

The in 1 illustrated tubular heater 10 consists of two sets of pipes 11 in which the heated water circulates, and each on opposite sides with two cross tubes, one upper each 12 and a lower one 13 , are arranged for connection and as a holder.

Every radiant tube 11 is made of a single profiled tube by bending inwards, so that the configuration results, in particular in the 2 and 3 can be seen.

Every radiant tube 11 is particularly limited by an outer ring 14 for the water circulation, the curvature of which extends over a desired angle, which is in any case less than 360 °.

By bending the radiation tube 11 in the middle becomes a continuous inner chamber 15 formed by the inner wall 16 of the outer ring 14 is limited.

In this continuous inner chamber 15 along is the air in each radiant tube 11 due to a chimney effect led from bottom to top, heated by the contact with this inner wall 16 and exits the top of the radiant tube 11 in the room and thereby increases the heating effect caused by the radiation from the wall of the pipe 11 is determined.

Furthermore, it comes as a result of the configuration of the radiation tube 11 to increase the radiation area caused by the presence of the inner wall 16 is determined, and therefore at the same temperature of the circulating water to a greater heating effect in space and therefore to a higher thermal efficiency.

Furthermore, since the heated water is only inside the outer ring 14 each radiant tube flows, the amount of water in circulation decreases, and therefore there is a saving in the boiler.

4 Provides the solution with a single row of radiant tubes 11 whereas 5 the solution is the two opposing flocks of radiant tubes 11 on the outside of the cross tubes 12 and 13 are fixed, as well as a third, middle row which provides, between the cross tubes 12 and 13 is arranged.

This third, middle row can be used both with round radiant tubes and with radiant tubes 11 be carried out according to the invention.

When solving in 1 are the radiation tubes 11 above with a sleeve element 17 connected to the surface of the outer ring 14 completely closes and a hole 18 for those in the inner chamber 15 having flowing air.

This sleeve 17 For convenience's sake, only on the side of the radiant tubes 11 is advantageously carried out in brass and / or colored to achieve an appealing aesthetic effect with a personal touch.
