Definitions
- the present invention relates to an electric heater, in particular for a vehicle.
- Modern motor vehicles especially motor vehicles, which do not include a fuel-powered internal combustion engine and are electrically powered often include electric heaters to provide the heat required for vehicle interior air conditioning.

- the present invention has for its object to provide an electric heater, which is reliably deactivated in case of defects.
- the electric heating device comprises a heat exchanger body which has a heat transfer surface.
- a medium to be heated may be present on the heat transfer surface and / or heat may be introduced by an electrical heating device, for example a heating layer. Indirect contact with the heating layer may suffice, for example via copper conductors which conduct heat well and form the electrical contact of the heating layer.
- the heat transfer surface is a surface of the heat exchanger body at which heat is introduced or discharged into the heat exchanger body as a function of an existing temperature gradient.
- the electrical heating ZUNE further comprises an at least partially closed cavity, wherein the at least partially closed cavity has an at least partially closed cavity partially delimiting wall portion adjacent to the heat transfer surface.
- the expression “adjoining” can be understood here to mean that the wall section partially delimiting the at least partially closed cavity forms on its side facing away from the at least partially closed cavity a part of the heat transfer surface on which the medium to be heated is present and / or generated heat is registered.
- a pyrotechnic charge is arranged in the at least partially closed cavity.
- the at least partially closed cavity has a further wall portion partially delimiting the at least partially closed cavity, to which an electrical connection line of the electrical heating device adjoins.
- the expression “adjoining” can be understood here to mean that the electrical connection line runs on the side of the further wall section facing away from the cavity, or alternatively, that the further wall section is formed by the electrical connection line itself.
- An at least partially closed cavity is a cavity which in some places may still have openings in wall sections delimiting it, for example in the form of gaps at or between edges of individual wall sections.
- the pyrotechnic charge may in particular be a temperature-sensitive material which reacts spontaneously chemically when an ignition temperature is reached, gas and solid particles being released.
- gas and solid particles In the course of the ongoing chemical reaction, for example, 10% of gases and 90% of solid particles can be liberated as reaction products.
- the gas and solid particle releasing chemical reaction can lead to a large increase in pressure within the at least partially closed cavity, which leads to bursting of the cavity, wherein the electrical connection line is interrupted by bulging of the further wall portion during the bursting of the at least partially closed cavity.
- the pressure increase is achieved by the thermal energy released in the chemical reaction, which heats the gas present in the at least partially closed cavity, and the reaction products liberated during the chemical reaction, in particular the released gas.
- the electrical connection line can be an electrical supply line to one or more heating cables, which can be connected in parallel or in series.
- the heating cables can be designed as conventional ohmic resistors. In particular, it is possible to use for the heating cables materials which have no intrinsic properties which counteract an undesirable rise in temperature.
- the electrical connection line can itself already be part of the heating cable.
- the electrical connection line can comprise a plurality of individual line paths, which can run separately in the region of the further wall section.
- the temperature threshold at which the temperature-sensitive material reacts represents the ignition temperature of the pyrotechnic charge.
- the ignition temperature of the pyrotechnic charge can be varied by appropriate choice of materials in wide temperature ranges, that is set.
- the ignition temperature of the pyrotechnic charge may be, for example, between 295 ° C and 305 ° C, which corresponds to a mean ignition temperature of 300 ° C. It is also possible, for example, an ignition temperature of about 260 ° C.
- the electric heater may have a plurality of pyrotechnic charges in different at least partially closed cavities, so that electrical connection lines can be interrupted at different points of the electric heater.
- the at least partially closed cavity partially delimiting further wall portion opposite to the at least partially closed cavity partially delimiting wall portion.
- the term "opposite" may be understood in particular as meaning that the wall section and the further wall section are connected by a direct straight line which runs completely within the at least partially closed cavity. can become.
- the pyrotechnic charge is arranged on the wall section, it is particularly easy to realize a directed force development by the pyrotechnic charge in the direction of the further wall section in order to be able to separate the electrical connection line particularly easily. This allows, for example, the use of a smaller pyrotechnic charge, which increases the safety of the electric heater.
- the wall portion and the further wall portion are not just opposite each other, but form mutually perpendicular surfaces, for example.
- the force released by the pyrotechnic charge during ignition is then deflected within the at least partially closed cavity, for example on a correspondingly curved wall section in order to direct it to the further wall section in a targeted manner.
- a slightly larger pyrotechnic charge may be required.
- the deflection allows a freer design of the electric heater.

It can be provided that the at least partially closed cavity between the heat transfer surface and another heat transfer surface, is entered at the electrically generated heat in the heat exchanger body is located.
- the further heat transfer surface is a surface of the heat exchanger body, is registered or discharged at the heat in dependence on an existing temperature gradient in the other heat exchanger body.
- the at least partially closed cavity is formed at least partially outside the heat exchanger body in a cover, which also leads the electrical connection line.

- the cover may be cork-shaped and clamped in the recess in the heat exchanger body which forms the other walls of the at least partially closed cavity.
- the at least partially closed cavity partially delimiting wall portion is at least partially limited by predetermined breaking points.
- the provision of predetermined breaking points delimiting the further wall section facilitates the controlled severing of the electrical connecting line which adjoins the further wall section.
- a smaller pyrotechnic charge can be used, since the force required to bulge the further wall section is less.
- the electrical connection line comprises at least one line break point, which lies in a region of the electrical connection line which adjoins the further wall portion partially delimiting the at least partially closed cavity. In this way, when the further wall section bulges out after the triggering of the pyrotechnic charge, a controlled separation of the electrical connection line can be realized.
- an anvil is arranged in the at least partially closed cavity between the pyrotechnic charge and the at least partially closed cavity partially delimiting further wall portion.
- the anvil can be accelerated in the direction of the further wall section by the temperature-induced release of the pyrotechnic charge and the resulting gases and solid particles which flow in the direction of the anvil, whereby the bulging of the further wall section can be supported.
- the anvil may consist of an electrically insulating material. An electrically insulating anvil, in particular if it at least partially penetrates the further wall section and / or remains in this connection, can lead to a particularly reliable and cutting edge. len separation of the electrical connection line, which takes place in particular without temporary formation of arcs.
- the pyrotechnic charge is arranged in a firing hatch.
- a primer is a standard component which is available in standard sizes in a cost-effective manner, so that the manufacturing costs and possibly maintenance costs, if the primer cap has to be exchanged, can be low.
- the primer cap can be arranged, for example, clamped in the at least partially closed cavity.
