Definitions

  • the invention relates to a panel radiator with at least one of two half-shells connected heating plate, wherein between the half shells an upper collecting channel, parallel to the upper collecting channel a lower collecting channel and the upper collecting channel and the lower collecting channel connecting heating channels are formed for a heating means, and with a the upper collecting channel formed vent opening of the heating plate, as well as with a spacer between the half shells at the vent opening, which divides the upper collecting channel in a front area arranged in front of the spacer and a rear portion arranged behind the spacer rear portion, and having a flow area through which at Venting the panel radiator air from the front area in the spacer and flows out of this through the vent opening from the heating plate, wherein the spacer flows through the heating medium between the rear region (H) and the Vent vent prevents.
  • the half-shells of such panel radiators are typically thermoformed from sheet steel and assembled and welded essentially under tolerance of the resulting deviations from the ideal shape.
  • spacers Before joining spacers are inserted into the heating plate there in the collecting ducts, where this Schuffenan gleich- and vents has to be welded to the heating medium in the further course of the production of the panel radiator or vent pipes.
  • the spacers can also be welded to the half-shells, so as to stabilize the shape of the collecting channel and the heating plate at the joint both during welding and on the finished panel heater. Usually, however, the spacers are only loosely inserted.
  • Such plate heaters and various forms of spacers are general, for example from the AT 411 493 B known.
  • the spacers are installed in the upper collecting channel so that between the outer circumference of the spacer and the inner sides of the half-shells in each case two approximately triangular passage cross-sections of the collecting channel remain open.
  • venting the known panel radiator air flows from the rear of the collecting channel - to which the spacers are closed - past the spacer in the front area and from there through the flow cross-section to the vent opening of the heating plate.
  • the invention has for its object to improve the efficiency of the plate radiator.
  • the spacer fills the upper collecting channel in the flow direction tight and has a relative to the flow cross-section smaller vent passage through which air flows from the rear area against a flow direction of the air from the front area in the spacer when venting the panel heater.
  • appreciable leakage currents of the heating means are effectively avoided by the spacer.
  • the air can also flow past, so that the air from the rear region - likewise counter to the flow direction of the air from the front region - at the flow cross section or the inner Free space of the spacer flows past to get in this way in the front area, from where - as the air there is also - an escape through the flow area is possible.
  • the ventilation channel prevents the heating medium from flowing through during operation of the panel radiator.
  • any leakage current of the heating medium is avoided in the rear region of the upper collecting channel.
  • the high surface tension of the water commonly used as heating means in combination with its greater viscosity vis-a-vis air, permits different generally known designs of the venting channel, which effectively avoid flow through.
  • the air from the two areas passes to two different ones Paths in the flow cross-section of the spacer and from there to the vent valve.
  • the spacer preferably has at least one polymer sealant which seals the upper collecting duct.
  • Such a spacer seals reliably and permanently even without extensive preparation of the mounting location of the upper collecting duct.

  • the support area in the region of the venting duct can have an increased wall thickness compared to the other areas.
  • the cross-section of the venting channel may depend on the environment of the spacer, i. typically decrease from the rear of the upper collection channel to the inner space of the spacer.
  • a conical shape of the venting channel is here a particularly preferred embodiment.
  • venting channel is that it is arranged in a polymer sealant which adjoins a support region on the outside and runs tangentially to the approximately annular support region.
  • a polymer sealant which adjoins a support region on the outside and runs tangentially to the approximately annular support region.
  • there is no connection between the rear portion of the upper collecting channel and the inner space of the spacer but there is a kind of overflow of the rear into the front region of the collecting channel, from where the air can escape through the flow cross-section of the respective heating plate.
  • the spacer or the vent channel integrated therein has a kind of bypass function in this case.
  • a pipe section may be embedded in a material having a significantly greater rigidity than that of the polymer material.
  • a piece of metallic tube will be used here.
  • a vent channel in the polymer sealant may alternatively or in addition to a vent channel in the metallic support region of the spacer are used.
  • a vent channel arranged in the polymer sealant should be arranged as far up in the upper collecting channel as possible in order to allow air to flow from the rear to the front region.
