Definitions

  • the present invention relates to a radiator element for a radiator, wherein the radiator element consists at least partially of aluminum.
  • radiator elements for radiators are known and find use, for example, in sectional radiators, in which more radiator elements are connected to a radiator as desired and required. Furthermore, radiator elements made of aluminum are known in which a heat-carrying medium, such as water or steam, is conveyed under pressure through a single chamber. Since aluminum is an expensive material, an attempt is made to keep the material thickness of the aluminum used as low as possible.
  • the conventional radiator elements have the disadvantage that the compressive strength is limited due to the structural design of only one chamber, since the chamber has, for example, a polygonal cross-section, which weak points are given. Therefore, for example, a steel tube is inserted into the chamber to increase the compressive strength, which makes the production more expensive and technical problems due to the different thermal expansion coefficients of the two materials and the different corrosion behavior occur. In addition, a poorer heat transfer is generated by the multi-layered.
  • the object is achieved in that the radiator element comprises at least two tubular chambers.
  • the advantage is that the tubular formation of the chambers weak points are avoided, which would limit the pressure resistance.
  • the material used for the radiator element may also be aluminum alloys, which have the desired properties, in addition to aluminum. Furthermore, it is of course conceivable to use other metals or plastics, if a radiator element to be produced for a corresponding radiator. However, the present invention is limited to the use of aluminum or aluminum alloys and to production by die casting or injection molding or by extrusion.
  • tubular chambers extend in a plane.
  • the tubular chambers extend in the direction of the longitudinal extension of the radiator element.
  • the radiator element is easy to manufacture.
  • the tubular chambers are parallel to each other. This embodiment also simplifies the production of a radiator element, and at the same time gives it a higher stability and a higher internal pressure resistance.
  • the tubular chambers terminate in inlet and outlet openings. These are for example tubular and pass through the ends of the radiator element. Each tubular chamber thus connects the supply of a heat-carrying medium with its derivative.
  • the inlet and outlet openings are preferably tubular, and correspond in length about the Width of a radiator element. But it is also an oval or angular configuration of the openings conceivable.
  • the radiator element has at least one heat-emitting blade.
  • a plurality of fins are arranged on a radiator element, whereby the heat-emitting heating surface is increased.
  • the lamellae may for example extend parallel to one another, in the direction of the longitudinal extent of the radiator element, and extend over the entire length of the radiator or only in parts thereof.
  • the slats can be flat, curved, or designed as a diaphragm.
  • the radiator element on its side facing the heatable space over its entire longitudinal extent may have a lamella in the form of a diaphragm, which blends the entire width of the radiator element to create a pleasant look. Due to the design and arrangement of slats, the stability of a radiator element is also increased.
  • the radiator element is manufactured in one piece in a die casting or injection molding process.
  • the high internal pressure resistance is achieved without additional components only by the tubular design of the chambers.
  • the inner walls of the chambers may also have a smooth or ribbed in the longitudinal extent of the chambers surface.
  • radiator element can be connected to further radiator elements.
  • a radiator may be formed having as many radiator elements as needed.
  • the connection is preferably made at the inlet and outlet opening, between which a seal, such as an O-ring may be provided.
  • radiator element 1 shown has two tubular chambers 2, which extend from a feed opening 3 to a discharge opening 4 and terminate in this.
  • more slats 5 are also arranged, which increase the heat-emitting heating surface.
  • On the side facing the heated space and the radiator element 1 facing lamellae 6 are arranged, which are formed as wide as the radiator element 1.
  • the radiator element 1 offers a more pleasant sight, whereby a radiator composed of these radiator elements 1 also beautifies, and a quasi-smooth front of the finished radiator is formed.
  • a protective lamella 7 is formed, which is a protection against bottom-side contact with objects.
  • This embodiment of the radiator element 1 is an efficient and rapid heat dissipation possible because also the material thickness of the radiator element 1 is low, so that not only a longer heating phase of the material must be done before the heat is released to the environment.
  • Fig. 2 shows a perspective view of a portion of the radiator element 1. It can be seen the discharge opening 4, in which the tubular chambers 2 end, which should be indicated by the opening 9 through which the heat-carrying medium flows from the tubular chambers 2 in the discharge opening 4 , In addition, in Fig. 2 to see well the columns 8 through which the ambient air flows when heated.
  • Fig. 3 shows a cross section through a heating element 1, wherein it can be seen that the heating element 1 is formed in one piece and without built-in parts.
