Definitions

  • a heating device of the type mentioned in the preamble of claim 1 in EP-A 9 136 6 falls under “Article 54.3 EPC” has already been proposed.
  • the carrier has a semicircular groove in a head surface, which is supplemented by a semicircular groove of a pressure piece screwed onto the head surface to form a pressure ring in which an oil-carrying pipe is clamped as a flow channel.
  • a U-shaped recess is arranged in the carrier, which forms the space for accommodating the heating elements made of cold-leaking material, the electrodes and the ductile inserts, as well as the insertion of wedges with which the heating elements, the electrodes and the inserts are wedged in between.
  • the object of the invention is to design the heating device of the type mentioned in the preamble of claim 1 in such a way that the heat is transferred from the heating elements to the flow channel in a particularly advantageous manner.
  • the object is achieved by the training specified in the characterizing part of claim 1.
  • the arrangement of the channel sections in the rod elements results in a splitting of the flow channel, which is accompanied by an enlargement of the area which improves the heat transfer and is wetted by the heating oil.
  • With the arrangement of the intermediate space between the rod elements there is a linear heat flow in the direct direction from the heating elements to the sections of the flow channel in the rod elements.
  • heating elements 1 made of cold-conducting material, the heating elements covering electrodes 2 for the power supply and electrically insulating ductile inserts 3 are pressed into an intermediate space 4 of a carrier, which has a flow channel for the Heating oil is united.
  • the carrier has two rod elements 5, 6 which are adjacent to one another at a distance forming the intermediate space 4.
  • the heating elements 1, the electrodes 2 and the inserts 3 are clamped in the space 4 with a wedge 7.
  • the rod elements 5, 6 each have at least a section of the flow channel. 1 to 3, three sections 9 of the flow channel are arranged one above the other in each rod element 5, 6.
  • each rod element contains only a section 9a of the flow channel.
  • the heat-emitting surface of the channel section 9a is enlarged by molded-in ribs, which contributes to improving the heat transfer.
  • inserted ribs or similar elements which increase the heat transfer area or cause swirling of the oil to be heated can be inserted into the sections of the flow channel located in the rod elements 5, 6 (not shown).
  • the rod elements 5, 6 engage in a holder 10, 11 in a sealed manner at each end. As indicated in FIG. 1, the rod elements 5, 6 can be soldered or welded into the holders 10, 11.
  • FIG. 3 A possible outline of the rod elements 5, 6 at the point of engagement in the holder 10, 11 is shown in FIG. 3.
  • the holders 10, 11 each have a transition space 12 (FIG. 1) which is connected to the channel sections 9, 9a of the rod elements 5, 6 and a connection section 13 of the flow channel.
  • connection sections 13 can, as shown in FIG. 1, be provided with a connection thread 14 for the connection of the oil inflow or outflow line. It is also possible to form one of the holders 10, 11 for connecting the nozzle of a burner (not shown).
