Definitions

  • the invention relates to a single or multi-row radiator according to the preamble of claim 1.
  • This is in particular a multi-row flat or panel radiator, with a flow connection and a return connection as well as a first through-flow radiator panel, preferably facing the room to be heated, and at least one further and preferably behind-flow radiator panel, with the radiator panels being connected via connection - And connecting pieces are connected to each other and the radiator plates consist of sheet metal shells to be connected, between which support parts provided with openings are provided.
  • radiators with inserts or support parts.
  • Known support parts/inserts of this type have the task of facilitating the welding on of fittings (connecting and connecting pieces) and/or of influencing the distribution/flow of the heating medium within a plate and thus the heat output of the radiator.
  • Radiators of this type are described, for example, in EP 1 227 290 B1, DE 32 16 922 C2 and DE-PS 2517 611.
  • an insert is arranged in one of the transverse channels in the area of a flow aisle, with the flow water being able to be conducted to the other transverse channel through the insert.
  • an insert is arranged in one of the transverse channels in the region of a connecting piece, it being possible to prevent the heating water from overflowing from the transverse channel into the connecting piece by the insert.
  • DE 32 16 922 C2 describes a heating element with an insert with which the inflow to the first sink channel of the heating plate is inhibited by the fact that the first outlet opening has a relatively small cross section, whereby a short-circuit flow is avoided, but not the first sink channel is completely shut off, so that heat is also emitted in the area of this channel. All of the above solutions are aimed at influencing the flow within a heating plate.
  • DE-PS 2517 611 describes a panel radiator whose flow is to be influenced by built-in parts in the T-pieces or by the inlet and/or outlet sockets.
  • EP 1227290 B1 describes a heating element arrangement with at least two plate-shaped heating elements, at least one heating element being designed as a heating water flow and another heating element being designed as a heating water return.
  • the plate-shaped heaters each have an upper transverse channel and a lower transverse channel between which a plurality of essentially vertically running vertical channels are provided, the vertical channels being designed with a defined different flow resistance to make the flow more even.
  • at least one insert part is arranged, which should preferably have the function of a support part at the same time.
  • At least one flow straightener is fixed in a collecting channel, which directs the heating medium flowing into the heating plate through a support part, which is connected to a connection opening of the heating plate, and the heating medium flowing into the heating plate via an adjacent riser channel in the direction of the middle of the heating plate and thus from the Affected afflicted with leakage currents supporting part away.
  • the leakage flows described in the prior art usually occur on the support part in its usual form without sealant when it is used alone for the targeted distribution of the heating medium or directing the flow in a heating plate area.
  • the use of a flow straightener according to the invention is more suitable, which almost completely intercepts and deflects the heating medium flow before the mentioned support part with leakage flows. Since the deflected flow of heating medium follows the laws of fluid dynamics after leaving the flow straightener, there is no need for an additional tight closure of the collection channel behind the flow straightener. As a result, difficulties with venting the heating plate and additional production costs can be avoided.
  • tubular or funnel-shaped flow straighteners made from steel or flow straighteners made from angled sheet steel or from arched or bent steel profiles.
  • the flow straightener is fixed with one end in the upper area of the riser channel, the lower area of which opens out on the support part adjacent to the connection opening of the heating plate, and with the other end in the horizontal collecting channel with the open cross-section pointing towards the center of the heating plate.
  • Heating means conducted through the flow straightener and away from the further support part located behind the flow straightener.
  • the radiator according to the invention is then designed as follows.
  • the front heating plate of the panel radiator consists of two half-shells which are profiled and fluid-tightly connected, with two parallel zuei nander running horizontal collecting channels between the two half-shells and between the collecting channels verti cal riser channels are formed for a heating medium.
  • a support part In the area of a heating medium connection opening penetrating a half-shell, a support part is fixed in an upper and lower collecting channel in such a way that opposing support surfaces of the support part come into contact with opposite inner surfaces of the two half-shells bordering on the heating medium connection opening.
  • Such support parts are, as already mentioned, well known and are described, for example, in the above-mentioned publications in various versions, statically and in terms of function.
  • the support parts can also be designed in a manner other than ring-shaped if they guide or guide the heating means as desired and thereby fulfill the support function.
  • the support part is fixed to a heating plate opening at the bottom in such a way that the radial opening corresponds to the connection opening for heating means in the half-shell.
  • the opening on the lateral surface opens into a vertical water channel. This is how the heating medium gets from the connection pipe into the vertical water channel of the front heating plate.
  • On the side of the support part opposite this opening there is advantageously a recess which allows the heating medium to flow past the lower horizontal water channel.
  • One end of the flow straightener is preferably in the vertical water channel through which the heating medium rises from the connection pipe, the other end is in the upper horizontal water channel and is arranged in the direction of the middle of the heating plate so that the heating medium flowing in from the vertical water channel into the horizontal water channel towards the middle of the heating plate.
  • the flow director is connected to the vertical water channel in a fluid-tight or non-fluid-tight manner.
  • the flow straightener is not fluid-tightly connected to the horizontal water channel.
