Description

The invention relates to a wall or a vertical one in particular Surface to be mounted, in particular band-shaped or strip-shaped heating and / or Heatsink with a back bar spaced from the wall and at least two or more heating or cooling pipe (s) running in the back web for receiving a heat or coolant fluid and / or a heater, e.g. a heating element, wherein the heating and / or cooling body has an upward web extension, of the back web or body, especially from the area of the upper (top) Heizbzw. Cooling pipe, goes off and with its end region of the wall or surface approximates and from the back bridge, especially from the area of the lower (lowest) Rohres, a downward, possibly with its end portion of the Wall, approximate, lower bridge extension is worn.

Radiators in the form of strips or strips are known from the prior art. Such radiators are installed on the wall at a short distance from the floor or attached to the wall with a variety of fasteners. Such radiators are heated with heating fluids, e.g. Hot water, and / or introduced into the heating pipes Electric heating elements heated. In principle, such radiators can also simultaneously Hot water and electric radiators are heated.

The disadvantage of the known radiators is that the structure is structurally complex and the convection and radiant heating power developed by them is not optimal.

The aim is further to represent an installation element that today's Requirements of energy prices, comfort requirements and low installation costs Takes into account. Due to an expected different tariff model for heating and Cooling energy, monovalent energy systems are no longer competitive. Furthermore, the Influence of environmental protection on the forms of energy in the future significantly the price determine. The possibility is to be offered, energy forms in the form of fossil Energy sources, solar energy, wind energy, biomass and other forms of energy to use.

According to the invention, these goals are at the beginning of a heating or cooling body mentioned type, achieved in that the back body and the at least two heating or Cooling tubes are formed in one piece, in particular from one by extrusion manufactured profile are formed.

Due to the fact that the smallest distance between the body and the Wall is located where the upper web extension approximates the wall, flows Air heated between the body and the wall through this gap essentially along the wall directed upwards and warmed the wall so that this heat begins to radiate, which creates a pleasant indoor climate. The cost of that Assembly and installation of such radiators are carried out by appropriate Modular design and simple assembly kept low. The product due to the simple design solution low manufacturing costs and transport costs. The Solution according to the invention is characterized above all by simplicity and assembly and Serviceability from. The radiator is manufactured in a continuous casting process, conditionally therefore low tool and manufacturing costs and is directly on site producible, which avoids long transport routes. The system can be used as Supplement or replacement of conventional elements for heating and cooling Serve rooms with almost all room condition requirements.

In terms of heating technology, it is an advantage if one is designed to face the wall directed convection flow on the back of the body or between the wall and the body of the end region of the upper web extension at a distance from the wall lies or in the assembled position of the body, the distance between the end region and the wall is smaller than the wall distance of the back web and / or the pipes. On this way the wall area above the body will be over some Height range intensely warms and radiates this heat into the room, creating a extremely pleasant indoor climate is achieved. The inside of the body is said to thus allow the heated air to be as laminar as possible and against the wall rises; if a corresponding curvature or a corresponding course of the Is present on the outside of the body, the support that arises along the outside is supported Convection flow of this flow and the wall to which the body is attached can be heated over a considerable area with the rising warm air.

In terms of flow, it is expedient if from the body, in particular from Back web or from the bottom (bottom) heating or cooling tube, one down, if necessary towards the wall, outgoing, lower web extension is carried, whereby the wall distance of the end region of the lower web extension is greater than that Distance from the wall of the end area of the upper web extension going upwards. On this way, for a defined air flow rate between the heating or cooling element and the wall is taken care of, or the amount of air that has passed through the top The bridge extension is limited and thus turbulence and undefined conditions avoided.

If the heating or cooling element is only used for cooling purposes, the Heating or cooling element at the appropriate height - if necessary with the upper one Bridge extension now pointing downwards - mounted on a wall. In this case strips cooled air between the wall around the heating or cooling element of the wall downward.

The air flow between the heating or cooling element and the wall to keep defined, it is provided that the web extensions and / or the Backrest and possibly the outer surface of the body presented to the tubes is closed or free of air openings. Such air passage openings would have a negative impact on the flow or cause turbulence, whereby the rising or falling air flow at most from the wall would be loosened or the heating or cooling capacity would be impaired.

It is also provided that the outer surface of the body at least over the Much of their extension has an outwardly curved or convex course, which is formed by straight lines and / or curved lines through this outer curvature the flow of the heated or cooled air along the Wall or the convex course supported.

The heating or cooling body, which can consist of metal or plastic, is optionally produced by extrusion. The back bridge with the tubes and the upper and the lower web extension and / or the holding webs and / or the further The web and / or the ribs and / or the reinforcing ribs is formed in one piece.

Attaching the radiator to the wall is simplified if at least one of the tubes and / or of the back web and / or the web extensions, preferably go off two, or are integrally formed with this, the cooperate with a holding device that can be attached to the wall, e.g. into this or can be snapped onto them, screwed onto them, hung onto them or the like. The Stability of the radiator or heat sink is increased if the distance from the back web after formed on the inside to form a further web connecting the or mostly two pipes or if there is a cavity between the tubes, the back bridge and the further bridge or a chamber is formed which, if necessary, by means of reinforcing ribs is stiffened.

It is also provided that the heating or cooling pipes and / or the Back bridge and / or the bridge extensions at least one, preferably several, ribs directed in particular obliquely downwards to the wall are formed by these ribs sloping downwards flow through, in particular those towards heated air flowing at the top is kept flowing; it is done by everyone such a rib has a certain turbulence in the air and even heating; the air flowing through between the upper web extension and the wall evened out.

It is particularly advantageous if the end or corner covering of a heating or Heat sink at least one profile strip is provided, which from the outside to the end region the upper and the lower web extension can be clamped or clipped on. To this Such bodies can be covered in particular in the end or corner area. Such end or corner covers can be mitred, the corner areas dress up.

The heating and cooling elements are installed in the usual way. From Corresponding inlet or return lines on the floor or wall side are the pipes supplied with heating or cooling fluid by making appropriate connections. The These connections are made in particular after the heating or Heat sink by means of the holding devices on the wall.
