Definitions

  • the invention relates to an electric heater according to the preamble of patent claim 1.
  • Such electric heaters can be used, for example, in the blow-by system of internal combustion engines or for heating a tank of an SCR system (Selective Catalytic Reduction).
  • SCR system Selective Catalytic Reduction
  • these have a heating section which is inserted into a correspondingly shaped receptacle of the component to be thermostated, for example a tank or a flow path of the blow-by gas.
  • This heating section goes into a plug or contacting part, in which the power supply lines for the heater are arranged.
  • resistance elements for example PTC heating elements are used, which are energized via the power supply lines of the contacting and as possible abut against a wall portion of the housing portion, so that the heat transmitted directly through the wall of the heating section and the adjacent wall of the component to be thermostated becomes. It is important that on the one hand to improve the heat transfer, a large heat exchange surface is present and further no insulating air gaps are arranged in the heat transfer path.
  • the problem is that it may come to an insulating air gap in the area of the system of the heating element to the wall due to tolerances in the production and temperature fluctuations in the operation of the heater or the component to be heated.
  • This disadvantage can be ruled out if the fits for the heating elements supporting areas are very narrow, but then the installation of the heater due to the required tight fitting dimensions is relatively difficult, so that in particular when using PTC components, the risk of damage of the heating element.
  • a heating device for heating flowing media which comprises a heat exchanger which can be heated by PTC resistors and which contains a slot-like pocket.
  • a cuboid substrate body is adapted in shape to the shape of the pocket and inserted into this.
  • the substrate body surfaces have recesses for receiving the PTC resistors and a contact spring.
  • the mutually facing surfaces of the substrate body and the pocket are bevelled inwardly from the insertion side.
  • the invention has for its object to provide an electric heater, in which an optimal heat transfer is ensured with simple installation.
  • the electric heater according to the invention has a heating section which can be inserted into a receptacle of a component to be thermostated.
  • the heater also has heating elements powered by power supply.
  • the heater is designed with an activation pin, which is adjustable from a release position into an activation position. In the release position, the respective heating element is in a play-loaded mounting position in which the heating element is not or only slightly in thermal contact with the wall or in electrical contact with the power supply lines. By moving the activation pin in the activation position, the heating element or the power supply is adjusted to an operative position in which the thermal and / or electrical contact is formed substantially free of play and area.
  • a heater in which the heating elements are initially arranged in a game-afflicted, not in a compact, contact with the wall to be heated or the power supply lines.
  • the activation pin is adjusted, so that the heating elements are adjusted or moved into their operative position. In this way, the assembly of the heater is much easier, since the heating elements are initially taken up with relatively large game in the housing. In the activation position of the activation pin this game is then canceled, so that the desired thermal and electrical contact is made with very good heat transfer.
  • the thermal and / or electrical contacting produced by virtue of the displacement of the activation pin is preferably accompanied by mechanical contacting, which ensures that the heating elements are pressed against the corresponding wall of the receptacle of the component.
  • the mechanical contacting can be carried out additionally or independently of the thermal and electrical contacting. In this case, the mechanical contacting of the heating elements indirectly, i. via intermediate components or directly.
  • the heater has at least two opposing heating elements, each associated with a spring element, wherein the activation pin dips in its activation position between the two spring elements to act on the heating elements by the spring force in the direction of the wall or in the sense of contacting.
  • two heating elements can thus be pressed against mutually opposite walls of the receptacle of the component to be heated, so that a significantly improved heat input with high power density can be realized due to the improved heat transfer surface compared to the cited in the introduction of the prior art.
  • the activation pin has an actuating projection projecting from a housing section and a heater-element-side activating section which comes into operative connection with the heating element for activating the heater by adjusting the actuating projection, wherein the activating pin can abut directly or indirectly on the heating element.
  • the structure of the heater is particularly simple if at least one of the power supply lines is formed with a spring element which, in the active position of the activation pin, acts on the heating element in the direction of the wall.
  • a spring element is attached to a power supply. This can be maintained, for example, via Crimplaschen the power supply.
  • At least one of the power supply lines is resilient, so that by the spring action tolerance deviations can be compensated and a flat contact of the heating element is ensured in its operative position.
  • the power supply can have an approximately U-shaped construction, wherein on a U-base, a spring effect providing concavity is formed.
  • both power supply lines are resilient and / or formed with spring elements, via which, for example, at least one heating element in the direction of its operative position can be acted upon.
  • a variant of the invention provides that a total of four heating elements are provided which face each other in pairs and between which spring elements and an activation pin is arranged.
  • the activation pin can be made of metal as a stamped and bent part with a folded activation section or made of plastic.
  • the activation pin is fixed in position in its activation position by frictional or positive engagement with a further component of the heater, for example, the aforementioned plug part.
  • This fixation can be done, for example, by latching, in which a tongue snaps into a recess of the activation pin or in kinematic reversal, a projection of the activation pins in a recess of the plug part or other housing-fixed portion of the heater.
  • the electrical heater is designed with PTC resistor elements.
  • An advantage of the described embodiment also that the heater is removable again. After deactivation of the activation pin, the heater is again powerless removable and can be replaced, for example, in case of service. However, it is important to ensure that the heater is not removed arbitrarily. It makes sense to use a special tool here.
  • FIG. 1 shows a view of a heater 1, which consists in principle of a heating section 2 and a plug part 4.
  • the power supply lines for contacting the heater 1 are arranged in this plug part 4.
  • the heating section 2 is inserted into a receptacle or pocket of a component to be heated, for example an SCR tank, the heating section 2 lying flat against the wall of this receptacle so that a good heat transfer is ensured.
  • a non-electrically insulating insulating film 6 which optimizes the heat transfer is provided in the abutment region on the receptacle, not shown, on the heating section 2, which will be described in more detail later.
  • a plug contour is attached, to which a correspondingly profiled plug connection of the power supply is applied, this plug contour 8 being designed so that a correct position mounting is ensured.
  • FIG. 2 shows a plan view of the plug part 4 FIG. 1 , It can be seen a plug flange 10, in accordance with the view FIG. 2 covers the heating section 2 and also acts as insertion limit for this.
  • the profiled plug part 4 engages with a peripheral wall a plug space 12, in which the above-mentioned plug of the power supply is at least partially immersed.
  • a plug space 12 At the bottom of this plug chamber 12 can be seen two projecting into this tongue-shaped power supply lines 14, 16 of the heating section 2 and also in this plug space 12 hineing protruding actuating projection 18 of an activation pin 20.
  • This actuating projection 18 is supported on two spring tongues 22, 24 of the plug part 4 and extends through the bottom of the plug space 12 into the heating section 2.
  • the spring tongues 22, 24 each have a locking projection which dips into recesses 26, 78 of the activation pin 20. In the release position of the activation pins 20, the spring tongues 22, 24 engage in the recess 78 of the activation pin 20, this is thus fixed in position against accidental displacement. If one acts on the actuating projection 18 in the illustration according to FIG. 2 From the viewer forth with a thrust, so the resilient engagement of the spring tongues 22, 24 is released, so that the activation pin 20 can be moved in the direction of the heating section 2. In the operative position, the Spring tongues 22, 24 then into the recess 26 of the activation pin and lock it. This feature is explained in detail below.
  • FIG. 3 shows the heater 1 according to FIG. 1 With removed insulating film 6.
  • FIG. 4 shows the plug part 4 alone without heating section 2. Accordingly, extending from the plug flange 10 down on both sides of the heating section ( Fig. 3 ) arranged holding legs 28, 30, which form practically end walls of the heating section 2. These holding legs 28, 30 are in turn designed with a profile 32, which allows a positional fixation in the recording of the component to be heated.
  • the plug part 4 of the heater 1 is preferably made by injection molding of plastic.
  • the latching lugs 33, 35 take the force (activating force) resulting from the insertion of the activation pin 20 onto the heating insert FIGS. 5 and 6 on.
  • FIG. 5 shows a representation of the heater 1 with removed connector part 4. It can be clearly seen the U-shaped insulating film 6, the open side areas by the above, in FIG. 5 not visible retaining legs 28, 30 are covered. In this illustration, one recognizes the two power supply lines 14, 16 and the activation pin 20 with its actuating projection 18. In this the above-described recess 26 is formed, in which the (non-visible) spring tongues 22, 24 resiliently engage, said resilient engagement relatively easily can be canceled.
