Definitions

  • the invention relates to an electrical heater designed as a heating element or tubular heating element with at least one coiled, wire-shaped heating element, which is embedded in a metal jacket, for example made of steel or stainless steel in a compact Isolierstofföllung of metal oxide, in particular magnesium oxide, embedded, wherein the heating conductor with out of the metal shell provided out guided electrical connections and switchable via at least one temperature-dependent activatable, electrical switching and / or control element.
  • both cartridge heaters and tubular heaters of the generic type have been known for some time. While the metal sheath of a heating element is closed at one end by a solid bottom and usually the electrical connections are led out from the other end of the metal shell, the metal shell of a tubular heater usually consists of a tube at both ends after filling by subsequently inserted end plates is closed, wherein the electrical connections of the heat conductor are usually passed through the two end plates to the outside.
  • a bimetallic switch is disposed in a tubular insulating case inserted into a terminal-side end portion in the metal jacket tube of the heating cartridge.
  • the bimetallic switch is on the one hand with the Schudrahtwicklung and on the other hand with an energy source in combination. Whether the Schudrahtchtl this heating cartridge is embedded in a compacted Isolierstoffmasse, can not be found in the description.
  • this mentioned cavity for fixing the switch or regulator and / or the connections must be poured separately by means of a synthetic resin.
  • the temperature-dependent switch and / or regulator within the second jacket tube can also be arranged in an insulating sleeve.
  • additional installation work is to be provided here by which in particular the manufacturing process of this known heating cartridge is made more expensive.
  • the integration of a compacted heating cartridge of the generally speaking "temperature component" only possible in the end regions of this heating cartridge, so that temperature fluctuations can only be detected in these end regions.
  • thermo components are usually extremely sensitive to high temperatures, so that, for example, such a temperature component in the ground area can be difficult to integrate, as a rule, the bottom of such a heating element after the introduction of the temperature component still needs to be welded, resulting in high thermal loads of the temperature component. Accordingly, an arrangement of "temperature components", for example, between two Schuleiterabitesen is not possible in particular in highly compressed heating cartridges. However, such high-density cartridge heaters are often used, and it is here, in order to achieve a targeted temperature control, desirable to be able to arrange the "temperature component" within the heating cartridge almost arbitrarily.
  • a method for producing a heating cartridge in which in an end region of the metal shell regulating and securing elements for the remaining area of the cylindrical metal shell embedded in a compressed insulating material Schudrahtchtln are arranged. According to this method, prior to insertion of the electrical components, the end portion provided for receiving the regulating and securing elements is reduced in diameter to a dimension corresponding to the final dimension of the diameter to which the remainder of the jacket tube is reduced during compression of the insulating material package becomes.
  • the cavity of a Isolierstoffhülse is provided, which is used in the pre-reduced diameter portion and separated by an insulating disc consisting of insulating material of the Schudrahtchtln.
  • the control and safety elements are located outside of the insulating material, in which the Schudraht Listeln are embedded.
  • the thermal connection to the heating elements is thus inadequate.
  • This deficiency is further increased by the fact that the control and securing elements receiving cavity with a thermally insulating potting compound, eg. B. silicone, is poured out.
  • the temperature-dependent devices can be connected only after filling of the metal shell with the terminals of the heating element or and used in the still open end of the metal shell. This causes a considerable costly work, which should be avoided by the inventive solution.
  • the invention has the object, in particular in highly compressed cartridge heaters to provide an embodiment in which arranged in a simple manner a temperature-dependent activatable electrical switching and / or control or a fuse element in different axial regions as close to the heating coil can be.
  • the inventive design a heating cartridge is provided, which is extremely easy to produce.
  • the switching or control element can be arranged in the immediate vicinity of the heating conductor, at the same time being embedded in the insulating material filling.
  • the switching or control elements can be integrated axially outside the heating conductor (s) in approximately any axial position in the metal shell or in the heating cartridge. So, as required, in one or each of the end regions and / or in one or more regions in between.
  • the portion of the metal shell with light or unver Whyter Isolierstoff spallung with the one or more switching and / or control (s) is in the end of the heating cartridge, from which the electrical connections of or from a the switching and / or control elements controlled heating element are led out of the front side of the metal shell.
  • the connections can be led out of the heating cartridge only on one side or on both sides.
  • the lightly or uncompacted portion is located in only one end region of the metal shell, while with two-sided lead-out of the connections, the light or uncompressed section in both end regions the heating cartridge is arranged.
  • a "single-sided" arrangement of the switching and / or control elements in only one end region can be provided independently of the lead-out of the connections.
  • the portion of the metal shell is arranged with slightly or non-sealed Isolierstoff spallung with the one or more switching and / or control elements in an axially between two sections of the metal shell with compressed Isolierstoff spallung.
  • the one or more portions of the metal sheath with lightly or uncompacted Isolierstoff spallung can each be in a portion of the metal shell whose cross-sectional shape and / or cross-sectional size of that corresponds to a portion of the metal shell with compacted Isolierstoff spallung.
  • the sections of the metal shell before compacting in the region of the insulating material to be compacted have a larger inside diameter than the portions of the metal shell, which contain only slightly or non-densified Isolierstoff spallung after completion.
  • fasteners e.g. mounted in the form of a mounting flange and welded or soldered to the metal shell. Since high temperatures (melting temperatures) arise during welding and soldering, which can be detrimental to control or regulating elements, it is important and advantageous if these welding or soldering operations can be carried out even before the temperature-sensitive components are inserted into the metal jacket. For this purpose, it is necessary that the portion of the metal shell to which the fastener is welded or soldered, already has its final shape. Due to the embodiment of claim 6, this advantage is perceived.
  • the metal shell is closed in its the outgoing terminals axially opposite end portion by an end wall. This reliably prevents the insulating material from escaping from the heating cartridge during the compression process.
  • claims 9 and 10 may be provided in the metal shell an additional formangepasstes metal tube, which rests against the metal shell over the entire surface both before the compression process and after the compression process.
  • an additional formangepasstes metal tube which rests against the metal shell over the entire surface both before the compression process and after the compression process.
  • This additional, integrated metal tube has a very good thermal conductivity, which directs the heat, especially for example in the "drying" of a provided in a washing machine heating element very quickly in the range of the temperature sensor or the temperature switch or the temperature fuse to these temperature elements faster to bring the "response".
  • the additional metal pipe functioning as a heat pipe can be used e.g. Made of copper or aluminum or any other suitable material with high thermal conductivity.
  • the jacket tube according to claim 9 axially either over the entire length of the metal shell or only over a partial area, in particular only over the compressed or the light or uncompressed portion of Isolierstoff spallung extend.
  • the sections of the metal shell before compression in the region of the "strong" to be compacted Isolierstoff spallung have the same inside diameter as the portions of the metal shell, which contain after completion light or uncompressed Isolierstoff spallung and that the sections of the metal shell have after compaction in the field of "strong” to be compacted Isolierstoff spallung a smaller inner diameter than the sections of the metal shell, which contain after completion light or uncompressed Isolierstoff spallung.
  • the switching and / or control elements are designed as a fuse, Platinmesswiderstand, NTC, bimetal switch or a combination of these.
  • the heating element is customizable as needed to the present "switching or monitoring tasks" in a simple manner.
  • the switching and / or control elements and / or their electrical connections to the heating conductor or the heating conductors are guided in an insulating, the switching and / or controls leading support body in the metal tube, which passages, in particular in the form of outside recesses and / or "inner" through holes for have the Isolierstoff spallung and / or form such passages with the metal shell.
