- Motor vehicle a method for producing an electric heater, a method for operating a heater and a use of a
- EP 1 912 028 AI From EP 1 912 028 AI it is known to stack a plurality of (electric) heating elements of a heating arrangement, wherein the heating elements are spaced apart by additional spacers and the individual heating elements are threaded over corresponding tie rods.
- the spacers should particularly preferably be made of the same material as the tie rods. Overall, the design of EP 1 912 028 AI is perceived as consuming.
- Liquid and / or air heater and to propose a corresponding use of a heater.
- This task is in particular by an electric heater after
- an electric heater preferably a fluid heater, in particular a liquid and / or air heater, preferably for a vehicle, more preferably for a motor vehicle, in particular for a passenger and / or truck (and / or for a watercraft and / or aircraft ), comprising a first (electric) heating element with a corresponding main body and at least a second (electric) Heating element with a corresponding main body, wherein between the
- Electrode heating elements a gap is formed, can be flowed through the fluid (ie, a liquid and / or a gas, such as air) to its heating, wherein the heating elements arranged on at least one between them, in particular (electrically) conductive, spacers together are connected, wherein the spacer is an integral part of the first heating element.
- the fluid ie, a liquid and / or a gas, such as air
- Heating elements (specifically, the first heating element, which does not preclude that a further spacer is associated with a further heating element) is formed.
- an efficiently operating (electric) heater can be realized with a comparatively simple production.
- the heating element can have exactly one or more than one
- Heating element may (exactly) have one or more spacers, which may be constructed and formed as described with respect to the spacer or the first heating element. Furthermore, a third, fourth or further heating element may also be provided. These further heating elements may also have spacers, which are formed and constructed, as described in connection with the one or more spacers of the first heating element. Insofar as in the
- solid constituents of the further heating elements in each case with respect to one of the further heating elements, a plurality of the further heating elements or all further heating elements and / or, based on a single heating element or on several or all heating elements, in each case with respect to a spacer, several - if provided - spacers or all spacers).
- the (respective) main body of the (respective) heating element is a portion of the (respective) heating element, which in particular structurally delimits from one or more optionally provided spacers (s). Inasmuch as (for example, for a second or further heating element) no spacer is provided as an integral part, the
- corresponding main body also define the complete heating element.
- the main body of the respective heating element forms
- the main body may be a plate-shaped body (a plate).
- the respective plate is preferably at least substantially planar (variations in thickness, if any, are particularly such that a maximum thickness is not greater than a minimum thickness plus 20% of the minimum thickness).
- the spacer (s) is preferably protruded at an angle from a main plane defined by the main body.
- the spacer may, for example, at an angle of at least 30 °, preferably at least 60 °, possibly at least about 90 ° relative to this main plane extend (at least over the majority, ie more than 50% of its total extent, possibly also can go crooked).
- a "solid" constituent of the first heating element is to be understood as meaning, in particular, a constituent which is connected to the corresponding main body such that it does not come loose or only lie loosely when the heating element is present separately only in that the electric heater in the assembled state comprises a plurality of heating elements, which in turn hold the spacer between them ..
- Such a spacer should in particular not be understood as an integral part of the first (or any) heating element.
- the spacer is permanently connected to the main body of the first heating element.
- an insoluble compound is in particular a compound to understand, which can not be solved without destruction (that is, by destroying the structure of the heating element) or at a break-up the (solid) connection can not be reversed again (without the addition of new fasteners).
- the spacer may be material, force and / or form-fitting with the
- Main body of the first heating element to be connected.
- the cohesive connection is preferably carried out by welding, in particular laser welding. However, gluing (alternatively or additionally) is also possible.
- the spacer is particularly preferably designed as an integral, in particular monolithic, component of the first heating element.
- An integral component is to be understood as meaning, in particular, a component in which there is no (unambiguous) material boundary between the spacer and the main body. A transition from main body to spacers is so
- a monolithic constituent is in particular a constituent in which the heating element as a whole is present as a uniform block.
- spacers and / or main body are constructed of several materials, this is preferably true for at least one of the respective materials, possibly for several or all of the materials.
- the spacer can at least be made
- heating layer include.
- a material of the spacer from which the spacer is formed to at least 50 wt .-% be a material from which the main body to at least 50%, preferably 80%, is formed.
- the respective or the respective) spacers of a heating element may constitute (in terms of weight) less than 20%, preferably less than 10% of the total weight of the heating element. If several spacers are provided, this can be for each individual and / or all
- the respective heating element may comprise a polymer structure which contains a polymer component and a conductive component, in particular carbon component.
- the respective heating element may each comprise one, in particular insulating, substrate and / or as polymer structure a polymer layer. Such a heater is particularly easy to manufacture and effective in operation.
- the first and / or second (electric) heating element can be electrically contacted via the one (or more) spacers, possibly only via the (or the plurality of) spacers.
- the spacer can be formed from the respective (in particular first) heating element by cutting (or at least partial separation) and / or punching and / or bending.
- the spacer is
- a connection to the other parts of the heating element ie in particular to the main body
- a connection to the other parts of the heating element ie in particular to the main body
- is not interrupted in particular not in sections
- the (respective) spacer in (direct) electrical and / or mechanical contact with a first and the second heating element electrically and / or mechanically connecting carrier and / or bridge element.
- a support member is in particular an element to understand that at least partially (possibly completely) carries the first and / or second heating element, ie in particular holds (possibly in cooperation with at least one or just another support member).
- a bridge element is in particular an element to understand the first and second heating element electrically (possibly also mechanically) bridged or connects.
- Carrier and / or bridge element can also with other components of the heating element (ie not only with the spacer) in electrical and / or mechanical
- a connection between spacers, on the one hand, and Carrier and / or bridge element, on the other hand, is preferably non-positive and / or material fit, for example by pressing and / or soldering and / or
