Definitions
- the present invention relates to one of two concentric tubes existing radiator, as described in the preamble of claim 1 is.
- tubular radiators are known, for example from CH-A-338478, and are used in apartment heating systems and especially in the bathrooms, where they are also often used as tumble dryers.
- the known tubular radiators essentially consist of two collecting tubes, one for the water inlet and the other for the water return after flow in the radiator, connected to one another by a series of parallel tubes which form a type of conductor. The space between two parallel tubes is used as a dryer for delicates.
- Similar examples of construction of tubular radiators are shown in the following patent documents: CH-A-675293, CH-A-675472 and EP-A-0564422. These radiators, which are very aesthetically pleasing, have two important disadvantages that make their use difficult.
- the individual horizontal tubes must be attached to each manifold by welding or otherwise. This means a high cost burden for the manufacture of such radiators, since the many welding points have to be carried out with the utmost care in order to guarantee radiator tightness on the one hand and perfect aesthetic appearance on the other. This point is particularly expensive to manufacture these radiators from difficult-to-work material, such as stainless steel, which would be particularly suitable for the function as a radiator in bathrooms. Furthermore, the ladder-shaped radiators, that is to say with collectors attached on both sides, have the disadvantage that, when used as a dryer, the delicates have to be inserted "vertically compared to the tubes" into the narrow gaps between two tubes, which can be extremely tedious .
- a heating or cooling device is known from CH-A-338478, which has the features of the preamble of claim 1.
- the known radiator has a tube in which at least one section is surrounded by a line through which the heat or cold carrier flows after the flows through the said tube and the outside surface of which the heat or cold is given off to the outside.
- the said tube can be bent in a meandering shape.
- the design of the double pipe according to this prior art in which the inflow liquid flows through the entire pipe length before it can flow back through the annular gap formed between the inner pipe and the outer pipe, does not regulate the temperature distribution over the length of the pipe allowed.
- this construction one is forced to accept the automatically forming temperature distribution along the length of the pipe, since there is no way to actively influence this distribution.
- the tubes with a circular cross-section are also considered to be more excellent in the field of the present invention.
- 1 shows an outer tube 1 curved in several points (in the specific case in 5 points) and forms a type of snake lying on one level. Inside the tube 1, an inner tube 2 is contained, which accordingly turns out to be substantially concentric compared to the outer tube 1 - this concept is then better explained below.
- the outer diameter of the tube 2 is smaller in comparison to the inner diameter of the tube 1, so that between the two tubes 1 and 2 a substantially annular cavity of adequate size for the passage of the liquid at the desired speed is formed.
- the concept of the snake according to the present invention has the expanded meaning of a flat, curved tube (flat snake) or three-dimensional, for example in the spiral snake, which is achieved by winding the tube around a virtual cylinder, so that windings with a desired Slope arise.
- a flat, curved tube flat snake
- three-dimensional for example in the spiral snake, which is achieved by winding the tube around a virtual cylinder, so that windings with a desired Slope arise.
- a first preferred form of such a snake shown in FIG. 4, it consists of at least two straight sections 3 and 4 connected by a curve 5. This is the simplest embodiment of the present invention.
- the snake consists of at least two first straight sections 6, 7 (see FIGS.
- the snake shown as an example in FIG. 1 includes six straight arms connected by five curved zones: This is also a graphic simplification of the inventive concept, since a real radiator according to the invention can have many more "branches" (that is, by means of two straight parts connected to a curved zone (serpentine bends formed), as many as are necessary to achieve the heat radiation effect required for use.
- the outer tube 1 has a connection on one side, shown in detail in FIGS. 2 and 3, while it is closed at the other end by an end plate 11.
- the inner tube 2 has a plurality of connection openings (14 ', 14 ", ..., 14 x) which are distributed along the inner tube (2).
- the tubular radiator and the manufacturing method of the same according to the invention make it possible to achieve the purposes mentioned in the introduction in an optimal way, they open the way radiators of a new dimension and of any type, without any welding and suitable for a variety of uses, particularly as dryers and radiators for bathrooms. Due to the absence of any welding, they also offer materials that would otherwise hardly be used for the purpose, the possibility of using them (such as stainless steel and aluminum) and thus the costly and demanding choice of colors can be dispensed with (think of the infinite variant of colors on the market).
