Definitions

  • the invention relates to a PTC thermistor heater according to the preamble of claim 1.
  • a heater is known from DE-OS 30 42 420.
  • PTC radiators of the aforementioned type generally contain several flat heating elements which, if necessary by an insulating plate with openings for receiving the heating elements, are kept at a mutual distance and are clamped between two electrode plates which supply current to the heating elements.
  • the heat developed in the PTC heating elements is emitted from their flat sides to the outside, which requires good heat conduction between the PTC heating element and the heat sink as a consumer.
  • the invention has for its object to provide a PTC thermistor of the type mentioned, which is particularly suitable for heating a tubular heat sink.
  • the invention provides a PTC heating element in which, with the aid of the angled edge strips attached to the covering element, the heat absorbed by the covering element is directed in approximately the same direction in which the side of the PTC heating element facing away from the covering element emits its heat.
  • the heat emitted on both sides by the PTC heating element is thus dissipated to essentially a single side, where it can be emitted to a heat sink which is accommodated in the channel which is formed in the carrier profile body.
  • This channel can in particular have a semicircular cross section, so that a tube with a circular cross section can be accommodated in it.
  • the individual parts of the radiator can be assembled in a very simple manner, without the need for any bending processes or casting, the individual components only need to be superimposed in a suitable manner and are then clamped together by at least one clamping bracket and secured to each other.
  • the PTC heater consists of a support profile body 1, a PTC heater from four PTC resistance elements 2 in the present case (FIG. 2e), a position plate 3, which secures the PTC resistance elements 2 in their position , and upper and lower contact plates 4 and 5 with connecting conductors 6, an insulating film 7, a heat-conducting bracket 8 and a spring clip bracket 9.
  • the carrier profile body 1 consists of a highly thermally conductive material, for example aluminum or copper, and has no bearing surface 10 for receiving the PTC heating element.
  • a channel 11 is formed below the support surface 10, which in the present case has an approximately semicircular cross section.
  • walls 12 extend upwards, which have laterally projecting edges 13 and 14 at their upper and lower ends.
  • a groove 15 is formed between each of these walls 12 and the walls that delimit the channel 11.
  • the position plate 3 has four openings 16, which are intended to receive the PTC resistance elements 2 and are adapted accordingly to their sizes.
  • the position plate 3 consists of an insulating material and has notches 17 on both sides of the edges.
  • the Contact plates 4 and 5 have at their longitudinal edges downwardly angled lugs 18 and 19 and cutouts 20 and 21, the lugs and the cutouts on the contact plates being aligned with respect to one another such that after the sandwiching of the contact plates , the position plate and the PTC resistance elements existing PTC heating element and the bending of the flags 18 and 19 do not touch the two contact plates.
  • This structure of the PTC heating element is already known from DE-OS 30 42 420.
  • the heating element is wrapped by the insulating film 7 (see FIG. 1) and in this state lies on the support surface 10.
  • the insulating film 7 electrically insulates the heating element from the carrier profile body 1, but ensures good heat conductivity. It is therefore made of a highly thermally conductive material.
  • the heating element thus insulated is covered by the heat-conducting bracket 8, which consists of a highly heat-conductive material and has a cover plate 22, to which are connected laterally angled edge strips 23 which engage in the grooves 15 in the carrier profile body 1 and on the adjacent walls thereof fit tightly.
  • the heat-conducting bracket 8 is held by the spring clip 9, which is locked on the edges 13 projecting on both sides on the walls 12 of the carrier profile body 1, as FIG. 1 clearly shows.
  • the spring clip 9 is preferably provided in the middle with a bulge 24 which presses elastically on the heat-conducting bracket 8. Possibly.
  • Several such spring clamps can be used if a particularly high compressive force and an associated improvement in heat transfer to the carrier profile body 1 is desired.
  • the heat given off by the heating element via the contact plates 4 and 5 and the insulating film 7 is absorbed, on the one hand, directly by the carrier profile body 1 and, on the other hand, by the cover plate 22 of the heat-conducting bracket 8, from which it passes over the edge strips 23 in the lower region of the carrier profile body 1 is derived near the channel 11.
  • the carrier profile body 1 can be clamped to a pipe (not shown) with the aid of a comparable spring clip (not shown), which is clamped at the edges 14, in order to give off heat thereon.
  • a comparable spring clip (not shown)
  • the cross section of the channel 11 need not be semicircular, but can also have any other shape adapted to the outline of the body to be heated.
  • Fig. 3 shows a modified embodiment of a carrier profile body 1a, which has two contact surfaces 10 ⁇ and 10 ⁇ with associated walls, grooves, etc., which are arranged at an angle to one another and enclose the channel 11 between them. In this way it is possible to attach two PTC heating elements to the carrier profile body or to carry out a different mounting of the PTC heating element.
  • an insulating film can be dispensed with if the carrier profile body consists of an insulating material, for example a ceramic material.
  • the insulation can also be carried out by means of insulating plates, as is already known per se from the prior art.
  • edge strips 13 and the grooves 15 are coordinated in their dimensions so that a good fit is achieved, so that sufficiently large thermal bridges arise.
  • a certain elasticity of the material of the carrier profile body can also contribute to this, which allows a slight spreading of the grooves 15 due to a corresponding fit of edge strips and grooves.
  • grooves can also be formed on the wall 12, into each of which one or more suitably designed spring clamps can be locked.
