Definitions

  • the invention relates to a heating device for preheating heating oil according to the preamble of claim 1.
  • a heating device has already been proposed in the preamble of claim 1.
  • 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 receiving the heating elements made of cold-conducting material, the electrodes and the ductile inserts, as well as the holding 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 lie next 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. Both 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 members 5,6 engage at each end sealed into a holder 1 0. 11 As indicated in Fig. 1, the beam elements 5,6 can be in the holders 1 0 may be soldered or welded. 11
  • FIG. 3 A possible outline of the rod members 5,6 at the point of engagement in the holder 1 0, 11 is shown in Fig. 3.
  • the holder 1 0, 11 each possess is a transition chamber 12 (Fig.1) connected to the channel sections 9,9a 'of the rod elements 5,6 and a connecting portion 13 of the flow channel in connection.
  • connection sections 13 can, as in Fig. 1 shown, be provided with a connection thread 14 for the connection of the oil inlet or outlet line. It is also possible for one of the holders 1 0, 11 to form a burner for the connection of the nozzle (not shown).
