Definitions

  • the present invention relates to an electric heater with a frame in which a preferably spring-loaded layer structure of heat-emitting radiator elements and arranged therebetween heat-generating elements comprising between parallel contact strip arranged PTC heating elements is provided.
  • Such an electric heater is for example from the DE 199 11 547 . US 5,854,471 . EP-0 350 528 or DE 197 06 199 known.
  • the layer structure is held under spring bias in the frame.
  • This type of mounting of the heat-generating elements and heat-emitting elements, which are also referred to as radiator elements, formed heating block has prevailed in practice.
  • alternative embodiments are also known in which the individual elements of the heating block are glued and held in the frame. In the latter case, the frame substantially forms the contact surface for sealing edges of air ducts, for example in a motor vehicle, through which cold air is guided in the direction of the electric heater and the heated by the electric heater warm air is discharged.
  • the frame also serves to re-load the spring force.
  • This spring can - as from the US 5,854,471 known - be formed as an integral part of the heating block.
  • the spring is arranged with respect to a good heat dissipation of the heat generated by the heat generating elements to the heat passed through the frame air flow adjacent to heat emitting radiator elements.
  • the other possible alternative in a design of the spring as an integral part of the heating block is from the DE 199 11 547 known. It is also possible to provide the spring in the region of the frame legs ( DE 197 06 199 ), so that the space spanned by the frame interior is essentially exclusively for receiving the heating block available.
  • Electric heaters of the generic type are used in particular in motor vehicles.
  • electric heaters are produced for different automobiles with different electrical heating power, which in each case requires an adjustment of the frame geometry.
  • the present invention is based on the problem to provide a generic heating device that can be easily and inexpensively adapted to different heat outputs.
  • the present invention proposes an electric heater having the features of claim 1. This differs from the generic state of the art by at least one placeholder included in the frame.
  • the placeholder element is a thermally ineffective consideration of the heater substantially ineffective element.
  • the choice of a suitable placeholder element is determined primarily by cost considerations.
  • the placeholder element is neither a heat-generating element, nor does it have the radiator or heat-emitting elements suitable suitability for heat dissipation to the air.
  • the placeholder element may heat up due to heat conduction in the plane of the heating block. Since the placeholder element is located in the interior of the frame and is accordingly flowed through by the air flowing through the frame, the heating of the placeholder element can also contribute to a small extent to the heat emission of the electric heater.
  • the placeholder element of the electric heating device according to the invention is located within the frame, ie is exposed in the interior of the frame and is flowed through by the air flowing through the frame.
  • the placeholder element can be on the edge the heating block, ie be provided directly between the heat-generating and heat-emitting elements and a leg of the frame. Alternatively, the placeholder element can also be an integral part of the heating block.
  • One or more placeholder elements can be provided.
  • radiator elements of identical dimensions and heat generating elements of identical dimensions are usually installed in the frame, alternating radiator elements and heat-generating elements on a regular basis.
  • the heat-generating elements can be replaced by one or more carrier strips whose dimensions substantially equal to the dimensions of the heat-generating elements, but do not contain PTC heating elements and their main function is to provide a flat contact surface for adjacent radiator elements (see. EP-0 350 528 ).
  • the placeholder element is preferably formed so that it fits into this grid.
  • the placeholder element in the width direction of the width of a radiator element or the cumulative width of a radiator element and a heat-generating element correspond.
  • the overall width of the placeholder element can also be composed of the width of a radiator element and a width of a part of the heat-generating element, for example a sheet metal strip or a sheet-metal strip and the position of the PTC heating elements.
  • the interior of the frame can be filled by replacing a radiator element and / or a heat-generating element and inserting a placeholder element varying with unchanged frame.
  • a particularly high flexibility in the adjustment of the heating power is achieved in that both the width of the heat-generating element and another of the width of the radiator element corresponding placeholder element is available. Accordingly, the electric heater can be adapted to the desired heat output while maintaining the frame usually produced by means of plastic injection molding in the manner of a modular system.
  • FIG. 1 to 3 a first embodiment of a heating device according to the invention is shown, the structure of which in the earlier patent applications of the applicant EP-1 432 287 A1 respectively.
  • EP-04 002 958 can correspond to described structure.
  • the electric heating device has a planar frame 2, consisting of two plastic frame halves 4a, 4b, which are clipped together, on whose one end face a flange element 6 with an integrally formed plug housing 8 is clipped.
  • the frame 2 forms at its outer edge encircling, extending parallel to the frame plane bearing surfaces 10, through which the frame 2 at the channel ends a ventilation duct, not shown, for example, a motor vehicle can be connected.
  • These contact surfaces 10 serve as sealing surfaces for the opposite ends of the ventilation duct, in which the electric heating device is inserted.
  • the contact surfaces 10 define an interior space 12, which dictates the maximum available space for forming a heating block 14 in the frame 2.
  • the heating block 14 consists of elongated elements, namely to a heat-generating elements 16, which are formed by a plurality of in a plane one behind the other PTC heating elements 18, which are each arranged between parallel metal strips 20.
  • the heating block 14 comprises heat-emitting radiator elements 22 formed from meandering bent sheet-metal strips 20.
  • the heat-generating elements 16 and the radiator elements 22 are formed essentially with the same length and the same thickness (dimension at right angles to the frame plane).
  • the heating block is preferably only in the width direction against the inside of the frame 2. In the present case, the heating block 14 is held in the frame under bias of a built-in frame 2 spring 24, which in detail in the European Patent Application 04 002 958 is described.
  • the frame 2 has on its side surfaces on a grid structure 26 with at right angles extending longitudinal and transverse webs.
  • the lattice structure 26 is designed such that the longitudinal struts are aligned with the heat-generating elements 16.
  • the heat-emitting radiator elements 22 are exposed on both sides of the outer sides of the frame 2 via windows formed by the lattice structure 26.
  • the heat flowing to the air flowing through the frame 2 forms a heating block, which is provided only in the bottom five rows of rows of the grid structure 26.
  • the top row of the layer structure is formed by a placeholder element 28, which is provided as a separate component (cf., FIG. 2) and which is provided on its one longitudinal side on the heating block 14 and on its other longitudinal side against the one in FIG Frame 2 held spring 24 is applied.
  • the placeholder element 28 is presently formed by a plastic injection molded part, which has a honeycomb structure 30, which is shown in more detail in Figure 2.
  • the honeycomb structure 30 has a longitudinal web 32 and a multiplicity of transverse webs 34, which are widened at locations provided corresponding to the transverse webs of the lattice structure 26.
  • the honeycomb of the honeycomb structure 30 have air passage openings 36, which are formed continuously in the direction of air flow, so that the air flowing through the frame are also passed through the blank holder element 28 by the electric heater can.
  • the dimensioning of the honeycomb structure 30 is preferably selected so that it opposes the air flow passed through the frame substantially the same air resistance, as a radiator element 22. This creates the same fluidic conditions in all parts of the air flow through the layer structure, which in view of a simple thermal design of the electric heater is preferable.
  • the installation space available for receiving heat-generating elements 16 and heat-emitting radiator elements 22 is reduced by the placeholder element 28 in the transverse direction of the layer structure.
  • the placeholder element 28 has a length substantially corresponding to the length of the radiator elements 22 or the heat-generating elements 16.
  • the thickness of the placeholder element 28, ie the extent of the same in the direction of air flow substantially corresponds to the thickness of a radiator element 22 and a heat-generating element 16, which with its metal strip 20 in practice for forming the ends of a radiator element 22 comprehensive edges usually a little thicker than the radiator element 22 is formed.
  • the placeholder element 28 is provided instead of a heat-emitting element 22 and parts of a heat-generating element 16.
  • the placeholder element 28 Between the placeholder element 28 and the adjacent radiator element 22 is only a metal strip 20, which is led out to a recorded from the flange 6 circuit board side of the layer structure to form a connection element. Consequently, the placeholder element 28 has a thickness which corresponds to the cumulative thickness of a radiator element 22, a sheet metal strip 20 and the position of the PTC heating elements 18.
  • the placeholder element 28 forms his respective, provided in the thickness direction longitudinal sides planar contact surfaces on which the sheet metal strip 20 and the spring 24 lie flat.
  • FIGs 4 and 5 show a second embodiment of an electric heater according to the invention, which has been explained in its basic structure to that previously with reference to Figures 1 to 3.
  • the same components are identified by the same reference numerals.
  • FIGS. 4 and 5 differs substantially only from the previously discussed embodiment in that the placeholder element 28 is provided in the middle of the layer structure, ie as an integral part of the heating block 14.
  • the length and width of the placeholder element 28 corresponds to the respective dimensions of the previously discussed embodiment.
  • a metal strip 20 at is on the one hand.
  • This sheet metal strip 20 forms the arrangement shown in relation to FIG. 4, 5 from the lower neighbor of the placeholder element 28.
  • a radiator element 22 Adjacent to the upper longitudinal side of the placeholder element 28 is on the other hand, another metal strip 20, which in turn forms the contact surface for PTC heating elements 18 on its opposite longitudinal side.
  • the lower longitudinal side of the placeholder element 28 rests only for electrical contacting of the adjacent radiator element 22 with the interposition of a metal strip 20 on this radiator element 22, located on the opposite side a complete heat-generating element 16.
  • the width of the placeholder element 28 substantially corresponds to the width of a Radiator element 22.
  • the thickness of the lower sheet metal strip 20 contributes substantially nothing to the overall thickness of the layer structure and can be easily compensated by the spring travel of the two springs 24. Consequently, it is not absolutely necessary to consider the thickness of a sub-layer of the heat-generating element, in particular a metal strip 20 in the design of the spacer element 28 in the width direction of the layer structure, at least in those cases in which the layer structure by one or more springs under bias in clamped in the frame.
  • the placeholder element 28 preferably should be formed with a width corresponding to the width of the radiator element 22 width.
  • a possible tolerance compensation can be effected by the spring 24.
  • further sheet-metal strips can also be inserted into the frame 2, which merely serve for the slight broadening of the layer structure.
  • the placeholder element is located in the middle of the layer structure and serves - as Figure 5 can be seen - the electrical insulation of various heating circuits within the heating block 14.
  • the heating circuit 15 is understood to be a subunit of the heating block 14 to be controlled or controlled separately.
  • the associated control or regulating elements can for example be connected directly to the frame 2.
  • the upper heating circuit 15a is electrically and thermally separated from the lower heating circuit, which means that substantially no heat conduction in the plane defined by the frame 2 transversely to the layers of the layer structure between the one heating block 15a and the other heating block 15b is directed.
  • the placeholder element 28 is preferably formed from an electrically and / or a thermally insulating material.
  • the placeholder element is an injection-molded plastic part which reduces the installation space provided for accommodating heat-generating elements 16 and heat-emitting elements 22 in the frame by approximately 17%, in the transverse direction of the layer structure , ie in the width direction.
  • this space is formed essentially by the opposite edges of the contact surfaces 10, since the spring 24 is an integral part of the frame 2 and is received between the frame halves 4a, 4b.
  • the space in question here is formed by the opposite side surfaces of the frame 4.
  • Figures 6 and 7 show alternative embodiments of the electric heater according to the invention, in which a placeholder element 38 is formed as an integral part of the frame 2 at its edge.
  • the placeholder element 38 is located here within the contact surfaces 10 and is traversed by the air.
  • the structure of the placeholder element 38 with air passage openings 36 and a honeycomb structure substantially corresponds to that of the placeholder element 28 of the previous embodiments.
  • the grid of the honeycomb structure 30 can be selected independently of the grid of the lattice structure 26.
  • the heating block 14 facing the longitudinal side of the placeholder element 38 limits the space provided for receiving the heat-generating elements 16 and the heat-emitting elements 22 in the frame 2 space and forms on one side of the contact surface for the spring-loaded heating block 14.
  • the other contact surface, i. the opposite, so the lower in Figure 6 contact surface for the heating block 14, is formed by the there recorded in the frame 2 spring (not shown).
  • a further spring element is formed at the upper edge, i. be provided between the placeholder element 38 and the uppermost element of the heating block 14.
  • the frame 2 shown in FIG. 6 with the placeholder element 38 integrally formed thereon can be produced in an economical manner, for example, by inserting into an injection mold a core which predetermines the honeycomb structure 30 of the placeholder element 38. Depending on the desired heating power of the heater, the installation space can be replaced by further cores, i. further placeholder elements are reduced. If, however, an electric heater with a higher heating power is desired, the core or cores is removed, so that substantially a frame shown in FIGS. 1 to 5 can be sprayed with corresponding frame.
  • FIG 7 a further embodiment is shown, which substantially corresponds to the embodiment shown in Figure 6, wherein, however, by two arranged on the front side of the heating block 14 placeholder elements 40 for receiving heat-generating elements 16 and heat-emitting elements 22 in The space provided for the frame in the longitudinal direction of the layer structure is reduced.
  • the provision or removal of the placeholder elements 40 accordingly requires a lengthwise adaptation of the individual layers of the layer structure and thus a modification to the plant layers preparing the respective layers of a device for producing the electric heating device.
  • it can also be thought of forming the individual elements of the layer structure subdivided in the length direction thereof and electrically and / or thermally connecting to one another at the interfaces which are preferably located behind the transverse webs of the lattice structure 16.
  • the space provided in the longitudinal direction of the layer structure can be changed without much effort by one or more, preferably on the grid of the grid structure 26 adapted placeholder elements.
  • the present invention is not limited to the embodiments shown.
  • a frame which has identical outer dimensions.
  • the frame may contain one or more placeholder elements to reduce the effective space for receiving a heating block.
  • the space is reduced, without it being necessary to change the outer dimensions of the frame. It can thus be very economical to produce electric heaters with different heat outputs.
  • heating systems are being considered, in particular, as auxiliary heaters for a motor vehicle with average heating powers of approximately 700 to 1200 W.
  • the placeholder elements can occupy up to 50% of the interior of the frame. If the placeholder elements have air passage openings, the desired end temperature of the airflow downstream of the electric heating device can be adjusted with the placeholder elements via a mixing of heated air passing through the heating block and cold air passing through the placeholder elements. In addition, it can generate a hot air stream enclosing cold air flow through which the plastic parts of the air duct provided downstream of the heater are thermally protected, provided that the or the placeholder elements fully or teilumffitlich on outer edge of the inner surface of the frame are provided.
