Definitions

  • the invention relates to a heating arrangement with a PTC element, in particular for a motor vehicle, according to the preamble of claim 1.
  • DE 101 44 757 A1 discloses a heating arrangement with a PTC element known for passenger vehicles, with an additional heating with a Radiator, which flows through during operation of the additional heating of heating air is, and with at least one air outlet opening in the foot of a Passenger compartment is provided, to which the heating air is passed.
  • a Radiator which flows through during operation of the additional heating of heating air is, and with at least one air outlet opening in the foot of a Passenger compartment is provided, to which the heating air is passed.
  • To be flexible Create a vertical temperature stratification in the passenger compartment to be able to, especially when sitting in the rear felt comfortable when the radiator is designed as an electrical PTC element, which is arranged directly at the air outlet opening in the foot area is.
  • Such a heater can still be desired.
  • a PTC element in the form of several Schuwaben arranged in a plastic frame not described in detail, which encloses the air outlet opening.
  • a heating arrangement with a PTC element is provided, the one the PTC element and this associated corrugated ribs, including other, corrugated ribs corresponding heat transfer arrangements to be understood, receiving plastic frame has, which is formed in two parts.
  • the connection between the two parts of the plastic frame by means of a clip connection, however, other compounds, especially one, are also included Sliding connection, possible.
  • the plastic frame preferably has at least one opening, in particular two openings, for two contact sheets on, with the plastic frame in the vicinity of the opening or the openings preferably as Plug is formed.
  • the plug is preferably at a right angle to the electrical Made contacting contact plates, wherein a cable and the Plug are preferably aligned parallel to the direction of the air flow. This allows a simple, space-saving arrangement.
  • the PTC element is on a contact plate by means of an adhesive connection appropriate.
  • an adhesive connection is easy to produce and forms a secure connection.
  • Preferred is a two-component silicone adhesive used. Preferred are on both sides attached to the PTC element contact plates, which are parallel to each other run.
  • a corrugated fin On the side facing away from the PTC element of the contact sheet is preferably a corrugated fin by means of an adhesive connection attached, in particular using a two-component silicone adhesive. Further, it is preferable on the side of the corrugated rib facing away from the PTC element another contact plate attached by means of an adhesive connection to the corrugated fin, preferably by means of a two-component silicone adhesive.
  • two contact sheets are formed such that they at their one end formed as part of a plug. This simplifies the assembly, because no connector must be attached to the contact plates.
  • the two contact plates are preferably L-shaped.
  • the attachment may preferably by means of one or more screws or by means of a clip connection respectively.
  • a single-stage PTC heating arrangement 1 with a PTC element 2 is the PTC element 2 between two contact plates 3 and 4 glued, in this case by means of a two-component silicone adhesive, wherein the contact plate provided with the reference numeral 3 is L-shaped is formed and with its angled end a part of a Plug 5 forms.
  • the designated by the reference numeral 4 contact plate is substantially rectangular in shape and parallel to the other Contact plate 3 is arranged.
  • a part 7 ' has a rectangular area, which the PTC element 2, the contact sheets 3 and 4, and the corrugated fins 6 and a box-shaped area connected thereto, which forms the outer part of the plug 5, on.
  • the second part 7 " the plastic frame 7 is C-shaped and designed on the first part 7 'clipped by means of a clip connection 8.
  • the two Legs of the second part 7 projections provided in corresponding in the first part 7 'provided openings protrude and a fast and secure connection of the two parts 7 'and 7 "allow, the second Part 7 "ensures that the assembly is held securely in the plastic frame 7 becomes.
  • first part 7 On the first part 7 'ribs 9 are arranged, which are parallel to each other in the direction run the air flow. The direction of the air flow is shown in Fig. 5b indicated by arrows.
  • the ribs 9 increase the strength of the plastic frame 7.
  • first part 7 'two slot-shaped openings 10th provided, which form a passage for the L-shaped contact plates 3.
  • Projections 11 are provided, which the additional fixation of the arrangement serve in the plastic frame 7.
  • the plastic frame 7 also has a portion 7 'arranged Tab 13, which means for attachment in an air duct a screw (not shown) is used (see Fig. 5b). Alternatively, the Attachment made for example by means of a clip connection.
  • the ratio of the free area which is about a x d corresponds to the total area b x c quite large, so that the pressure drop in the air duct is relatively low, so that a relatively low fan performance is required.
  • a corresponds to the permeable width
  • b the total width
  • c the total length
  • d the permeable length of the Heating arrangement 1 without plug 5.
  • the ratio of a x d to b x c at approx. 84%.
  • the heating arrangement with PTC element as decentralized Heater outside the air conditioner, for example, in appropriate Air ducts in the A-pillar, B-pillar, C-pillar or arranged in a door.
  • FIGS. 8 to 12 second embodiment substantially corresponds to the previously described first embodiment, so that same and equivalent elements are provided with the same reference numerals.
  • the arrangement of two contact plates 3, 4 in a two-part plastic frame 7, consisting of a first part 7 'and a second part 7 ", corresponds to that of the first embodiment, however, the frame 7 no clips connection 8, but a sliding connection 8 'on, in particular Fig. 11 can be removed.
  • the second part 7 " a suitably trained slot provided laterally over a Constriction between the PTC elements 2, the contact plates 3, 4 and the corrugated rib 6 receiving area and the plug 5 of the first part 7 'is pushed, so that the heater assembly 1 securely held together becomes.
  • the frame 7 ribs. 9 providing a distance between the heated elements, hereinafter also understood as the contact plates 3, 4 and the corrugated fin 6 will cause, and the frame 7, so that the heat load of the frame 7 is reduced.
  • the frame 7 is made of a plastic with an increased temperature resistance, such as polyamide.
  • the frame 7 itself forms an insulating wall, so that the heat loss As low as possible and adjacent components, such as Seat belts, due to the increased temperature in the case of a zunningens not impaired or damaged.
  • the insulating wall can also be formed separately.
  • PTC elements 2 which has an operating temperature from between 80 ° C and 120 ° C, unlike the conventional PTC elements with a surface temperature of 130 ° C. up to 165 ° C.
  • Appropriate protection can also be achieved through use a regulator can be achieved when reaching a certain temperature in the environment of the heating arrangement the power is reduced or temporarily shuts off the power supply completely.
