Definitions

  • the present invention relates to a heat-generating element having at least one PTC heating element and an insulated housing surrounding the PTC heating element, as well as electrical traces resting on opposite sides of the PTC heating element.
  • Such a heat-generating element is as part of a Zuloomers for a motor vehicle, for example from the EP 0 350 528 known.
  • Other heat-generating elements are for example from the DE 32 08 802 .
  • the problem with such generic heat-generating elements is that a good contact resistance is to be provided by good mechanical contacting between the conductor track and the PTC element, so that energization of the heat-generating element without substantial heating at the phase boundary to the PTC element is possible , This requirement becomes particularly relevant when the heat-generating element is to be supplied with high operating voltages of about 500 volts or more.
  • the conductor track which is usually formed by an electrically conductive sheet metal, encapsulated by a surrounding the heat-generating element sleeve which applies the conductor with a certain pressure against the at least one PTC element (see above DE 32 08 802 ).
  • the PTC element is surrounded with the mutually adjacent tracks with a metallic sleeve, which is coated on the inside with silicone rubber, so that the conductive metal sheets are held in the insulating sleeve.
  • This arrangement alone is not sufficient to build up a sufficient contact pressure for pressing the strip conductors against the PTC element. Accordingly, the entire layer structure is surrounded by a press plate.
  • the previously known heat-generating element is relatively sluggish, ie heat generated by the PTC element is relatively poorly dissipated to the outside.
  • the As a result, the previously known heat-generating element has a poor thermal efficiency and reacts relatively slowly to changing thermal conditions.
  • radiator elements formed on both sides of the heat-generating element by means of meandering bent metal sheets. These are applied under spring bias against the heat-generating element. Since the interconnect between the radiator element and the at least one PTC element is provided so as to be freely movable, the interconnect is applied against the PTC element via the spring force. In this construction, however, there is the problem that creepage currents migrating away from the radiator element and / or the frame, especially when the heat-generating element is operated at high voltages, can not be avoided. In addition, the current-carrying parts are exposed on the outside of the heat-generating element, which is also questionable for reasons of safety.
  • the aforementioned disadvantage with respect to a poor heat conduction has also from the DE 28 04 749 known heating element, in which three generic heat-generating elements are arranged at an angle of 120 ° about a cylinder axis. Between the individual heat-generating elements are cylindrical circular segment pieces of an electrical insulating material, in each of which a flow channel for a to be heated by the heating cartridge fluid are recessed. Such a structure is insufficient particularly in the convective removal of heat generated by the PTC element by air. Heat can not be dissipated to the required extent by the PTC element.
  • the present invention is based on the problem of specifying a heat-generating element in which a good contact between the conductor track and the at least one PTC element can be ensured and which is electrically insulated from the environment in an improved manner.
  • the present invention provides an improved electrical heater for a motor vehicle.
  • the present invention provides a heat generating element having the features of claim 1.
  • This has a housing consisting of a housing shell element and a shell counter element, which abut each other with the interposition of a sealing strip and the at least one heating element encloses sealed.
  • this known per se holding frame is formed as a housing which holds the PTC heating elements and not only in a plane in a predetermined manner and spaced from each other, but also seal the PTC heating elements from the environment.
  • the invention proposes a shell-shaped housing which comprises a housing shell element and a shell counter element.
  • the two housing elements lie with the interposition of a sealing strip to each other, so that the peripherally enclose the at least one PTC heating element cross edges of the housing elements sealing the PTC element.
  • the housing is formed as a flat, preferably in several PTC heating elements on a heat generating element elongated strip-shaped component whose height is preferably not higher than the height of the corresponding PTC heating elements. At least one housing element, namely the housing shell element should grasp the edge of the PTC heating element.
  • This edge-mounted version lies with the interposition of the sealing strip close to the shell counter-element, which may be formed, for example, in the manner of a housing shell, or may be formed substantially as a flat strip, so that the lateral edges of the housing shell element substantially over the entire height of PTC heating element extend.
  • the shell counter-element which may be formed, for example, in the manner of a housing shell, or may be formed substantially as a flat strip, so that the lateral edges of the housing shell element substantially over the entire height of PTC heating element extend.
  • a sealing strip in the sense of the present invention can be, for example, a sealing element arranged between opposite end faces of the housing shell elements, which is supported on said end faces.
  • the sealing strip can also be made in one piece on the housing shell element or the housing shell counter element be educated.
  • a tongue and groove connection In such a tongue and groove connection, the spring forms the sealing strip.
  • the spring engages in a formed on the other housing member groove, which is preferably dimensioned such that the two housing elements are movable within certain limits transverse to a plane which extends parallel to the conductor tracks.
  • the tongue and groove connection also prevents direct access to the interior of the housing from the outside and thus forms a sealing strip in the context of the present invention.
  • the above-mentioned mobility of the two housing elements relative to each other in a direction transverse to a plane extending parallel to the two interconnects allows a certain adjustment of the clear distance of the parallel conductor tracks, so that manufacturing tolerances are compensated especially on the part of the PTC heating elements can, without having to dispense with a flat and good conditioning of the PTC or the heating elements on the respective tracks.
  • a corresponding mobility is also due to a sealing strip having a certain compressibility and is supported between opposite end faces of the housing elements. All that is important here is that the two housing elements are movable relative to one another at least slightly transversely to the plane which extends parallel to the conductor tracks, without the seal of the interior of the housing being lost.
  • the mobility should preferably be designed so that the said manufacturing tolerances due to different thickness PTC heating elements and / or thermal stresses during operation of the heat-generating element can be tracked by relative movement between the two housing elements. It is assumed that this mobility of a few tenths of a millimeter is sufficient. This does not necessarily mean that greater mobility must be prevented constructively. Rather, the heat-generating element is particularly suitable for installation in a layer structure consisting of heat-generating elements and radiator elements, which is held under compressive stress, so that the conductor tracks abut the PTC heating element at all times and the structural integrity of the housing by the externally acting pressure force is ensured.
  • the heat-generating element usually forms a strip-shaped layer of a layer structure, which comprises at least one, preferably two on opposite sides of the heat-generating element adjacent radiator elements. These are arranged in a frame.
  • the radiator elements and the heat-generating elements lie as elongated layers of the layer structure within the frame.
  • the housing in this case serves to fix the PTC or the heating elements within the position of the heat-generating element, in a direction transverse to the longitudinal extent of the heat-generating element and preferably also in the longitudinal direction of the heat-generating element.
  • spacers or the like may be provided on the housing, which hold the arranged in a plane behind the other PTC heating elements at a predetermined distance from each other.
  • the housing elements are preferably formed from a highly insulating plastic, such as an electrically high-quality polyamide or Teflon.
  • the material used in each case should have a high tracking resistance.
  • the CTI value for the PTC element received in the housing should be at least 400, preferably 600.
  • the sheet metal strip is preferably located directly between the insulating layer and the PTC heating element and adjacent thereto and serves to energize the same.
  • the previously mentioned injection-molded part can be in conventional plastic injection-molded part, preferably from the above-mentioned electrically high-quality plastic.
  • a housing element may be formed as a CIM component (Ceramic Injection Molding).
  • the ceramic powder for producing the at least one housing element is mixed with plastic in order to obtain a flowable suspension, which is processed with an injection molding machine.
  • the injection-molded green compact is freed from the binder. Thereafter, the Bönling thus obtained compacted to a sintered ceramic part.
  • a housing element designed as a sintered ceramic part can cooperate with the injection-molded plastic housing element.
  • This ceramic part can rest for example as a flat plate on the cross-sectionally U-shaped and the at least one PTC heating element laterally grasping plastic injection molded part with the interposition of the sealing strip.
  • the band-shaped ceramic part in turn forms the outside of the housing.
  • a further metal strip is usually provided between the ceramic part and the PTC heating element to which the PTC heating element is applied directly and via which the PTC heating element is energized.
  • the PTC heating element may form a substantially U-shaped housing element as a ceramic component. It has proved particularly expedient to form the ceramic parts as alumina molded sintered parts.
  • both housing elements may be formed as plastic injection molded parts.
  • both housing elements d. H. Housing shell element and shell counter element as identical components form, each of which has a U-shaped cross-section and each hold a part of the PTC heating element at the edge.
  • the shell shell element and the shell counter element have substantially half the thickness of the PTC heating element.
  • Each of the housing elements summarizes a part of the PTC heating element as a shell element laterally.
  • the sealing contact of the two housing elements on the sealing strip can be done by an external force, which is introduced after installation of the heat-generating element in an electric heater from the outside to the heat-generating element.
  • This may be a force acting from the outside on the layer structure spring force, for example, from the EP 0 350 528 is known.
  • the sealing strip may also have an adhesive function, so that the housing shell element and the housing counter element are glued to one another via the sealing strip. This bond can be such that the components are permanently and firmly attached to each other. It is also conceivable to apply the sealing strip so that it exerts a tensile force on the opposite housing elements, so that manufacturing tolerances, in particular justified by the PTC heating element, as well as expansions due to temperature differences can be compensated by the sealing strip, for a uniform elastic bias provides the housing elements, which usually each include a sheet metal strip, which lie directly on one side - regularly the top or bottom of the PTC heating element and energize this.
  • the two housing elements are preferably applied under bias against each other.
  • This bias is either generated by the sealing strip or - which will probably be the rule - via an externally acting on the housing clamping force, which leads to a compression of the sealing strip for sufficient sealing of the two housing elements against each other.
  • inventive heat-generating element as part of a layer structure, for example according to EP 0 350 528 is arranged under spring tension in a frame, the adhesive sealing strip, the two housing elements add to a unit that is easier to handle and install during assembly.
  • the present invention further claims an electric heater with a frame and a layered structure received in the frame, which comprises at least one heat-generating element according to one of claims 1 to 13 and at least one radiator element extending parallel to the heat-generating element.

  • Typical radiator elements are formed from a meandering bent metal strip or formed as an extruded aluminum profile and preferably have at least one planar contact surface for the installation of the heat-generating element.
