Description
Positiv-Temperature-Coefficient-Heizelemente werden unter anderem auf keramischer Basis hergestellt und sie verfügen über dynamische Charakteristika. So zum Beispiel übernehmen PTC-Heizelemente ohne Zusatzanbauten die Funktionen der Heizung, der Temperaturregelung und der Temperaturselbstbegrenzung. Vorzugsweise werden diese PTC-Heizelemente in der Industrie, der Kosmetik sowie in der Medizintechnik verwendet. Hinzu kommt der Einsatz dieser Heizelemente in Haushaltsgeräten und in Automobilen (Dieselheizsysteme). Sie dienen der Erwärmung von Festkörpern, Behältern und von Flüssigkeiten mit statisch/dynamisch -Strömung.Positive temperature coefficient heaters are manufactured on a ceramic basis and they have dynamic Characteristics. So for example take over PTC heating elements without additional attachments the functions of the heating, the temperature control and the temperature self-limiting. Preferably, these PTC heating elements used in industry, cosmetics and medical technology. Added to this is the use of these heating elements in household appliances and in automobiles (diesel heating systems). They serve the warming of Solids, containers and of liquids with static / dynamic flow.
PTC-Elemente werden aus dotierter, polykristalliner Keramik auf der Basis von Bariumtitanat im Sinterverfahren gefertigt. Sie zählen zu den Kaltleitern. Sie haben einen Widerstandstemperaturverlauf mit stark positiven Temperaturkoeffizienten. Im Bereich einer Regeltemperatur wechselt der Widerstandswert von nieder- zum hochohmigen Verhalten und steigt dabei sprungartig um mehrere Zehnerpotenzen an. Daraus erhält man ein dynamisches, selbstregelndes Heizelement. Das PTC-Heizelement kann ganz einfach an einen zweipoligen elektrischen Stecker verkabelt werden, was einen großen Vorteil dieser Heizelemente darstellt. Durch den geringen elektrischen Verdrahtungsaufwand ist ein simpler Aufbau und Anschluss gewährleistet. Ein weiterer Vorteil dieser Heizelemente ist, dass die Leistungsregulierung kontinuierlich und völlig verschleißfrei arbeitet. Es werden hierbei zum Beispiel durch ständiges Ein- und Ausschalten der jeweiligen Systeme keine anfälligen Kontakte beansprucht.PTC elements are made of doped polycrystalline ceramics based on Barium titanate produced by sintering. They count the PTC thermistors. They have a resistance temperature curve with strong positive temperature coefficient. In the range of a regulation temperature the resistance changes from low to high impedance behavior and rises suddenly by several orders of magnitude. This gives you a dynamic, self-regulating heating element. The PTC heating element can simply wired to a two-pin electrical plug be what a big one Represents advantage of these heating elements. Due to the low electrical Wiring effort is a simple construction and connection guaranteed. Another advantage of these heating elements is that the power regulation continuously and completely wear is working. For example, they are and switching off the respective systems claimed no vulnerable contacts.
Weitere bisher bekannte besondere Eigenschaften dieser PTC-Heizelemente sind, dass diese zum Beispiel in elektrischen Spannungsbereichen von 12 Volt bis 24 Volt genauso wie in Spannungsbereichen von 100 Volt bis 240 Volt und in Sonderspannungen von zum Beispiel 400 Volt und mehr einsetzbar sind, im Fehlerfall besteht bei Keramikbauteilen keine Brandgefahr.Further previously known special properties of these PTC heating elements are that, for example, in electrical voltage ranges of 12 volts to 24 volts as well as in voltage ranges of 100 volts up to 240 volts and in special voltages of for example 400 volts and can be used more, in case of failure there is no ceramic components Fire.
Bekannte
PTC-Heizelemente werden zur Zeit meist als kleine Vorwärmeeinheiten
in den oben genannten Industriezweigen verwendet. Sie sind derzeit
bekannterweise scheibenförmig
aufgebaut. So zum Beispiel auch in Kraftfahrzeugen zur Erwärmung des
Dieselkraftstoffes. Solche Heizvorrichtungen sind beispielsweise
bekannt aus der
Da PTC-Heizelemente derzeit noch nicht als größere Elemente, außer in Kfz.-Klimaanlagen, verbaut werden und da die Verarbeitung dieser Elemente derzeit noch scheibenförmig ist, hat es sich die vorliegende Erfindung zur Aufgabe gemacht, diese PTC-Elemente als Anwendungen in größeren Bauarten, dies vorzugsweise als wabenartiger Aufbau zu verwenden. Die Verwendung der sinnvollen Ausnutzung der Wärmeübertragungsfläche, Wärmeerhaltung mit relativ wenig Energiezufuhr wird bis dato bei diesen Heizelementen nicht im großen Stil ausgenutzt. So stellt der Erfinder hierbei ein Heizungssystem vor, bei welchem die PTC-Heizelemente nicht herkömmlich in scheibenförmiger Weise aufgebaut sind sondern bei welchem die PTC-Heiz- und Wärmeleitelemente wabenförmig aufgebaut und mithilfe einer vorzugsweisen Nanomerbeschichtung isoliert werden die dann zum Beispiel auch als Heizkörper oder als Wärmeleitung ohne Wärmeverlust in der Haustechnik verwendet werden können.There PTC heating elements currently not yet as larger elements, except in Kfz.-air conditioners, installed and because the processing of these elements is currently disc-shaped, It is the object of the present invention to provide these PTC elements as applications in larger designs, this preferably to be used as a honeycomb structure. The usage the sensible utilization of the heat transfer surface, heat conservation with relatively little energy supply is to date with these heating elements not in the big one Exploited style. Thus, the inventor in this case provides a heating system in which the PTC heating elements are not conventionally disc-shaped are constructed but in which the PTC heating and Wärmeleitelemente honeycombed structure and isolated using a preferred nanometer coating which then, for example, as a radiator or as heat conduction without heat loss can be used in home automation.
Der wabenförmige PTC-Elementeaufbau hat vor allem den großen Vorteil, dass nahezu unendliche Fließmengen eines Mediums exakt temperiert werden und dass hierbei beim Mediumfluss, bzw. bei der Erwärmung nur geringe Temperaturunterschiede zwischen den jeweiligen Keramikkammern (Waben) entstehen. Hierbei kann ein großer Vorteil sein, dass die Vorlauftemperatur an der Heizstelle durch den geringen Wärmeverlust in den Rohrleitungen nicht mehr so hoch sein muss und sich daraus Rohstoffeinsparungen erwirtschaften lassen. Dies kann unter anderem in Anwendungen wie die der Elektrospeicheröfen wie auch zum Beispiel bei der Gas- und Ölheizung von positiven Nutzen sein. Durch die Eigenschaften der PTC-Elemente kann hierbei eine Überhitzung der Heizungsleitungen komplett vermieden werden. Dies ist vor allem auch ein großer Vorteil, wenn die Heizelemente als Fußbodenheizung in der Haustechnik installiert werden, da hierbei die Bodentemperatur wunschgemäß temperiert werden kann. Hierbei stellt die einfache Installation der Heizelemente zudem noch einen weiteren großen Vorteil gegenüber der herkömmlichen Verlegung von Rohren dar.Of the honeycombed Above all, PTC element construction has the great advantage of being almost infinite flow amounts a medium are exactly tempered and that in this case the medium flow, or during heating only small temperature differences between the respective ceramic chambers (Honeycomb) arise. This can be a great advantage that the Flow temperature at the heating station due to the low heat loss in the piping does not have to be so high and out of it Generate raw material savings. This can be, among other things in applications such as the electric storage heaters as well as for example the gas and oil heating to be of positive use. By the properties of the PTC elements this can cause overheating the heating pipes are completely avoided. This is above all also a big one Advantage if the heating elements as underfloor heating in home automation be installed, since in this case the temperature of the floor tempered as desired can be. This is the simple installation of the heating elements also another big one advantage over the conventional one Laying of pipes
Auch schlägt der Erfinder eine Warmwasserleitung vor, die mithilfe von PTC-Elementen, einem Temperaturverlust auf dem Weg vom Boiler zum Wasserhahn entgegenwirkt. Hierbei ist darauf zu achten, dass die PTC-Heizelemente zum Beispiel gegen Ablagerungen mit vorzugsweise spezieller Nanotechnologie vorbehandelt werden. Damit ist es auch einrichtbar, dass an Kaltwasserleitungen das fließende Wasser mithilfe eines derartig isolierten und beschichteten PTC-Elements entsprechend erwärmt wird ohne diese mit einem Boiler zu verbinden. Somit ist auch ein entsprechendes Umwälzen des Mediums möglich.Also, the inventor suggests a hot water line, which counteracts a temperature loss on the way from the boiler to the tap by means of PTC elements. It should be ensured here that the PTC heating elements are pretreated, for example, against deposits with preferably special nanotechnology. It is therefore also possible to set up the cold water pipes to heat the flowing water using a PTC element insulated and coated in this way without connecting them to a boiler. Thus, a corresponding circulation of the medium is possible.
Eine weitere Variante der Erfindung stellt das Einfassen von PTC-Heizelementen in zum Beispiel zwei Hüllen dar, wobei die PTC-Heizelemente hierbei mit einem speziellen wärmeleitfähigen und Strom isolierenden Verguss umhüllt werden. So ist es zum Beispiel vorstellbar, dass diese PTC-Heizelemente entsprechend in schützende sowie zum Beispiel auch leitende Metallhüllen gefasst werden können.A Another variant of the invention provides the enclosure of PTC heating elements in for example two cases in which the PTC heating elements in this case with a special thermally conductive and Power insulating encapsulation sheathed become. For example, it is conceivable that these PTC heating elements accordingly in protective as well as, for example, conductive metal sheaths can be taken.
Außerdem schlägt der Erfinder PTC-Heizelemente vor, welche mit einem Lack zur Isolation eingefasst sind.In addition, the inventor proposes PTC heating elements, which are edged with a paint for insulation are.
Der Erfinder schlägt zur Isolation des PTC-Elements auch eine Kunststoffumspritzung vor, welche mit entsprechenden Kontakten versehen ist.Of the Inventor proposes for the isolation of the PTC element also a plastic extrusion before, which provided with appropriate contacts.
Durch die Eigenschaften der PTC-Heizelemente schlägt der Erfinder auch einen Frostwächter vor, welcher auf Grund der Außentemperatur komplett selbstständig arbeitet und eine gewünschte Temperatur des Mediums nie unterschreiten lässt.By the properties of the PTC heating elements, the inventor also proposes a Frostguard before, which due to the outside temperature completely independent works and a desired temperature never fall below the medium.
Somit sind die Einsatzbereiche eines PTC-Elements mit einer derartigen vorzugsweisen Nanomerbeschichtung bei der Erwärmung bzw. Temperaturüberwachung eines Mediums nahezu unbegrenzt. Diese Eigenschaft wird bei einem größeren Mediumfluss durch einen wabenartigen Aufbau sehr unterstützt.Consequently are the applications of a PTC element with such a Preferably, nanometer coating during heating or temperature monitoring a medium almost unlimited. This property is at a larger medium flow very much supported by a honeycomb construction.
