Definitions
- the present invention relates to a component having the features of the preamble of claim 1 and a method for producing such a component.
- the invention therefore relates in particular to components with a base body, a heating layer for electrically heating the component and electrical contacts for contacting the electrically heatable heating layer, with a heating layer arranged on the base body and/or integrated in the base body for electrically heating the component being provided.
- the components to be manufactured have to be heatable and also have to meet - sometimes high - requirements with regard to, for example, a particularly smooth surface finish.
- the heating of certain components that are used in a cabin e.g. should be placed very close to the surface.
- the heater should only be separated from the outside by a thin decorative layer, for example a foil, a layer of leather or a coating, and should ensure a smooth outer surface and feel that is as smooth as possible.
- Another example would be heaters that should be placed very close to the surface, for example for improved or optimized energy efficiency, and at the same time the outside of the surface should be flat throughout, for example for technical reasons.
- Such technical reasons can exist, for example, because a flush connection to a supporting surface has to be guaranteed, as can be the case with battery heaters or in a cabin.
- Wires or the like that serve as such a heater or at least as a contact for the heater often do not have one due to their inherent thickness desired influence on the surface to be heated (which is referred to here as the front side).
- the object of the invention is therefore to provide a heatable component and a method for its production, the influence of the heating on the surface structure of the component being minimized—in particular eliminated.
- heating layer has at least one extension that is folded over onto a rear side or front side of the base body, and the electrical contacts are arranged on that part of the at least one extension that is located on the rear side or front side of the base body.
- an electrically heatable heating layer provided with at least one extension is applied to a front side of the base body
- the at least one extension is folded over onto a rear side or a front side of the base body or the heating layer is applied to the base body with the at least one extension in the folded-over state and
- the heating layer is contacted at that part of the at least one extension that is located on the back or front side of the base body.
- an electrically heatable heating layer provided with at least one extension is integrated into the base body
- the at least one extension is folded over onto a back or front side of the base body or the heating layer is integrated with the at least one extension in the folded state into the base body and
- the heating layer is contacted at that part of the at least one extension that is located on the back or the front side of the base body.
- the heating layer is only applied to the base body with at least one extension in the open state or integrated into it and then the at least one extension is folded over onto the back or front side of the base body.
- the heating layer is applied to the base body with the at least one extension when it is already folded over or integrated into it.
- the heating layer could be applied to the base body with one of the extensions already folded over or integrated into it and another extension could then be folded over.
- the result is a base body with a heating layer which has at least one extension folded over onto the rear side or front side.
- the extension can be in contact with the end face of the base body or at a distance from it.
- the heating layer can be integrated into the base body in various ways.
- the integration can take place during a primary shaping process for producing the base body.
- the heating zone could be back-molded or encapsulated in an injection-molding process for producing the base body.
- the at least one extension can be in contact with the base body or at a distance from the base body.
- the at least one extension of the heating layer on the edge area of the front side has—at least essentially—the same basic structure as the rest of the heating layer, no or only extremely little influence on the surface structure of the cover layer can be assumed.
- the component according to the invention is resistant to damage and, if damage does occur, is easy to repair.
- extension can also be folded over at an opening in the base component.
- the inner peripheral area of the opening is then also considered to be the end face.
- the contacting on the back or the front is also reflected in a higher electrical safety against electric shocks and a simpler connection to the power supply of the entire arrangement (i.e. on the system side).
- the manufacturing method according to the invention has the further advantage that it is very simple and can therefore be carried out with relatively little effort.
- thermoelectric de-icing systems for aircraft, sensors, cabin heaters or battery heaters.
- An example of the use of the invention would be heating of certain components that are used in a cabin, for example, of an airplane, ship, rail or road vehicle and can therefore be placed very close to the surface, for example for the purpose of improved or optimized energy efficiency.
- the heater can only be delimited from the outside by a thin decorative layer, for example a foil, a layer of leather or a coating and ideally ensure a smooth outer surface and feel that is as smooth as possible.
- heaters that can be placed very close to the surface, for example for improved or optimized energy efficiency, while at the same time the outside of the surface can be flat throughout, for example for technical reasons. In this way, for example, a flush connection to a support surface can be ensured, as can be advantageous with battery heaters or in a cabin.
- the invention can basically be used in all situations where the surface structure on a side to be heated (the front side) of the component is important and at the same time there should preferably not be too great a distance between the heating layer and the surface.
- a side of the base body that has to be heated and where a desired (e.g. smooth) surface structure is to be achieved, which according to the invention is minimally or not at all impaired, is referred to as a front side within the meaning of the invention.
- the back can be understood as a side facing away from the front. There can be one or more end faces between the front side and the back side.
- the back will be the side that faces away from the front.
- the back or front can generally be considered as one where the surface structure is of lesser importance.
- the base body itself can be layered and/or flexible (at least in some areas). Alternatively or additionally, the base body can be a “solid” or hollow (volume) component, at least in some areas.
- the base body can be made of plastic or be designed as a plastic composite component. If the base body is metallic and/or conductive, an insulating intermediate layer (or intermediate layer) can be advantageous.
- optional adhesive layers are also conceivable as intermediate layers.
- Intermediate layers can also be advantageous between the heating layer and the top layer, e.g. to achieve a special surface structure.
- the at least one extension is folded over onto the back or the front side of the basic component can be understood to mean that the at least one extension extends over to the rear side or the front side in order to be able to produce the electrical contacts for the electrically heatable heating layer there.
- the folding does not have to be done only when the heating layer is already on the base body.
- the at least one extension can also be present in the partially or completely folded over state and placed on the base body in this form.
- a device in particular an aircraft, a ship or other devices that have a battery, for example, with a component according to the invention, the heating layer being electrically connected to an electrical network of the device via the contacts.
- the base body could also be referred to as a substrate to which the heating layer is applied.
- the heating layer can be designed to cover the full surface or partially of the base body.
- the at least one extension is folded over from a front side to the back or front side of the base body and/or the at least one extension protruding from the base body is folded over to the rear side or front side of the base body.
- the fleece layer may have a backing. This represents an embodiment of the invention that is particularly easy to produce.
- the felt element can be designed as a printed conductive layer.
- a conductive lacquer which is arranged on the carrier and/or the base body, can be provided for the felt layer. This can serve to further simplify the fixing process, in particular the fixing process according to the invention, because a conductive lacquer can be applied in a particularly simple manner. This is especially true when the carrier or base is flexible because the conductive paint can tolerate deformation even after application.
- the conductive paint can be arranged on the carrier over the entire surface, in a grid, in strips and/or in a meandering manner.
- a full-area, grid-like, strip-like or meandering design can also be provided for the heating layer if the heating layer is realized in a way other than with a conductive lacquer (for example with a metal foil).
- the conductive lacquer can be applied to the carrier by spraying methods, printing methods (for example screen printing or offset printing) or direct application (for example using a brush-like device).
- the conductive lacquer can be part of the heating layer or can form the heating layer, the conductive lacquer can also be printed on as an alternative or in addition.
- the carrier can have a layer made of a foil, of a textile and/or with a lattice carrier.
- the carrier and therefore the heating layer does not have to be a full-surface layer, but can have recesses and the like.
- the at least one extension can preferably be arranged on one side of the heating layer and in particular can only extend over part of a length of the side (can also be understood in the sense of an edge).
- extension there can be a single extension on which there are two or more contacts for the electrically heatable heating layer. Alternatively, one extension can be provided for each contact.
- a cover layer (e.g. a decorative layer) can be provided, which is preferably arranged on the heating layer or the base body.
- the cover layer can have a layer made of leather, a textile, in the form of a foil, made of wood and/or a metal.
- the cover layer can be arranged on the heating layer, ie the heating layer is then arranged between the base body and the cover layer.
- the cover layer can also be arranged between the base body and the heating layer if the cover layer “only” acts as a cover layer for the base body.
- the cover layer can preferably be applied to the base body after the heating layer.
- the heating layer can be applied to the base body in combination (i.e. simultaneously) with the cover layer.
- the shape of the heating layer and/or the cover layer can be adapted to the front side of the base body or a part thereof.
- the contact can be designed as a printed contact and/or as an etched and/or soldered contact.
- the contact can have a stranded wire, a strip made of solid material and/or a braided strip made of a conductive material.
- the heating layer and/or the cover layer can be attached to the base body by gluing, screwing and/or clamping.
- the attachment of the heating layer and the cover layer can be carried out separately or can be solved by a joint attachment (e.g. screwed or clamped).
- the heating layer can also be held on the support by the cover layer.
- FIG. 1a shows an exemplary embodiment of a component 1 according to the invention.
- the component 1 has a base body 2, on the front side 3 (the side that has to be heated and whose surface structure is relevant) a heating layer 5 and above that an (optional) cover layer 4.
- An extension 7 can be seen, which is folded over onto the rear side 8 of the component 1 .
- the folding is implemented as a (double) fold.
- the heating layer 5 can be electrically heated by applying an electrical voltage to the contacts 6--e.g. by ohmic heat from a conductor in the heating layer 4 (i.e. heat generated by the resistance of the conductor).
- FIG. 1 b the component 1 from FIG. 1 a is shown in a perspective view of the front side 3 of the component 1 . It can be seen that the contacting has no effect whatsoever on the surface of the cover layer 4 . Thus, the surface structure of the cover layer 4 is not impaired by the heating layer 5 or its contacting.
- FIGS. 2a to 2c Various options for the configuration of the at least one extension 7 are shown in FIGS. 2a to 2c. This can extend over the entire edge length of one side of the heating layer 5 or over only part of the same.
- the heating layer can have a carrier 11 and a heating element arranged thereon.
- the heating element is formed as a layer of conductive lacquer 12.
- FIGS. 3a and 3b for possibilities of the precise configuration of the arrangement of the conductive lacquer 12.
- FIG. 2b It is also apparent from FIG. 2b that more than two contacts 6 can be present, for example in order to achieve better energization of the heating element (ie the heating layer) or in order to be able to heat different areas of the heating element separately.
- Fig. 3a a meandering arrangement of the heating element (in this embodiment, a conductive paint 12) is shown.
- FIG. 3b shows an (essentially) full-area arrangement of the conductive lacquer.
