Description

The invention relates firstly to a method for conducting a heating medium according to claim 1, on the other hand a plate radiator according to claim 2 such a plate radiator according to claim 2.

Method and a "serial" Plattenheizkörper according to the preamble of claims 1 and 2 discloses DE 200 14 519 U1 , wherein the Heizmittelstrom is introduced through a centrally located Heizmittelanschluss in the hot plate and passed depending on the connection by one of two attached to the two upper corners Heizmittelrohren in the other heating plates.

In the known panel radiator the Heizmittelstrom after leaving the first riser channel in the upper collecting channel into two streams - one to the one and one to the other - divided, which then divide on the sink channels, flow together again in the lower collecting channel and together to the drain off further riser channel. In the heating plate of the known panel radiator, the guide element always reduces the free passage in the lower collecting channel for one of the two streams Direction of the further riser. In the sink channels on both sides therefore different heating medium flows and thus on both sides of the hotplate different heating outputs during operation.

task

The invention has for its object to achieve a more uniform heating power.

solution

Starting from the known method, it is proposed according to the invention that the heating means in the lower collecting channel of the heating plate is divided into two streams and the streams are passed separately through the further riser channels from the heating plate and into the at least one further heating plate. The separation according to the invention of the heating medium flow in the lower collecting channel allows a symmetrical design of the flow cross sections for both streams and thus leads to a more uniform heating power of the plate radiator.

Starting from the known panel radiator is proposed according to the invention that two Heizmittelrohre each separate a stream of the heating medium from the riser channels of the heating plate in the at least one further heating plate. The panel heater according to the invention enables the method according to the invention described above and is characterized by the advantages described for this.

Preferably, a panel heater according to the invention has two Heizmittelanschlüsse for connecting the panel radiator, each with a flow line or a return line of a heating circuit. Such a panel radiator according to the invention can, if required, be traversed by the heating means in both directions between the heating medium connections 6, depending on the structural requirements.

a water model of the panel heater according to the invention in ten phases from the inflow to complete filling with the heating medium.

The in FIG. 1a shown plate heater 1 has a heating plate 2 (the "front panel"), which faces away in the assembled state of a wall 3 of a not further shown space and two other identical heating plates. 4

On a bottom 5, which faces a bottom, not shown, of the room in the mounted state, the plate heater 1 has approximately on both sides depending one (in FIG. 2a shown in detail) Heizmittelanschluss 6 for connection to likewise not shown, prepared in the room piping of the heating system. Starting from the Heizmittelanschlüssen 6 lead Heizmittelrohre 7, which are integrated together with the Heizmittelanschlüssen 6 in a connection part, to the (front) heating plate 2 and to the other (rear) heating plates. 4

On an upper side 8 of the panel radiator 1, the heating plate 2 is connected at both corners 9 by two Heizmittelrohre 10 with the other heating plates 4. At the Heizmittelrohren 10, the plate heater 1 has two functional connections for connecting a bleed valve, not shown.

In the FIG. 1b sectional heating plate 2 of the panel heater 1 according to the invention is welded from two half-shells 11, which are deep-drawn profiled sheet steel. Between the half-shells 11 are formed by the profiling on the underside 5 of the panel radiator 1, a lower collecting channel 12, at the top 8, an upper collecting channel 13 and between the collecting channels two first riser channels 14, sink channels 15 and two further riser channels 16.

At two heating medium openings, not shown, at the lower collecting channel 12 of the heating plate 2, a guide element 17 is welded to the heating medium pipe 7 coming from the heating medium connection 6. The guide element 17 is for the substantially directed introduction of a in the FIGS. 2a to k formed in the "water model" heating means 18 in the first riser channel 14 and at the same time as a spacer between the half-shells 11. The guide element 17 has a flow opening facing the riser channel 14 in the mounted state.

Two separating elements 19 are welded to not shown Heizmittelöffnungen at the upper collecting channel 13 of the heating plate 2 with the leading to the function terminals Heizmittelrohren 10. The separating elements 19 are sheathed with rubber sleeves 20 and separate the upper collecting channel 13 in each case from the further rising channels 16. Through the further rising channels 16 and the separating elements 19, heating means 18 or air can flow from the heating plate 2 to the functional connections during operation of the panel heating element 1.

Also in Figure 1c shown in section further (rear) heating plate 4 of the panel heater 1 according to the invention is made of two profiled sheet steel deep-drawn half-shells 21 welded. As in the heating plate 2, a lower collecting channel 22, an upper collecting channel 23 and between these sinking channels 24 are also formed in the further heating plate 4.

Two guide elements 25 are welded to heating medium openings, again not shown, on the upper collecting channel 23 of the heating plate 4 with the heating medium tubes 10 coming from the functional connections. By the guide elements 25, the heating means 18 is introduced in the operation of the plate heater 1 coming from the front heating plate 2 in the further heating plate 4 or air out of the other heating plate 4 to the function connections.

Two further guide elements 26 are welded to heating medium openings, again not shown, at the lower collecting duct 22 of the further heating plate 4 with the heating medium pipes 7 leading to the heating medium connections 6. By one of these guide elements 26, the heating means 18 is in the operation of the panel heater 1 from the further heating plates 4 are derived to the functioning as a return connection heating medium connection 6.

• Das Heizmittel 18 wird zunächst aus dem Heizmittelanschluss 6 in den unteren Sammelkanal 12 der Heizplatte 2 (Figur 2a), durch den ersten Steigkanal 14 zum oberen Sammelkanal 13 (Figur 2b), aus dem oberen Sammelkanal 13 durch die Sinkkanäle 15 zum unteren Sammelkanal 12 (Figur 2c), aus dem unteren Sammelkanal 12 durch die weiteren Steigkanäle 16 (Figur 2d) und durch die Heizmittelrohre 10 in den oberen Sammelkanal 23 der weiteren Heizplatte 4 eingeleitet (Figur 2e), strömt durch die Sinkkanäle 24 (Figur 2f) in den unteren Sammelkanal 22 und aus diesem zum Rücklaufanschluss 7 (Figur 2g).

The FIGS. 2a to g illustrate on the basis of the various stages of a Heizmittelfront a first method according to the invention in operation of the panel heater 1. Here, for simplification, only one of the other heating plates 4 is shown:

• The heating means 18 is first from the heating medium connection 6 in the lower collecting channel 12 of the heating plate 2 ( FIG. 2a ), through the first riser channel 14 to the upper collecting channel 13 (FIG. FIG. 2b ), from the upper collecting channel 13 through the sink channels 15 to the lower collecting channel 12 (FIG. Figure 2c ), from the lower collecting channel 12 through the further riser channels 16 (FIG. Figure 2d ) and introduced by the Heizmittelrohre 10 in the upper collecting channel 23 of the other heating plate 4 ( FIG. 2e ) flows through the sink channels 24 (FIG. FIG. 2f ) in the lower collecting channel 22 and from this to the return port 7 ( Figure 2g ).

Both functional connections of the panel heater 1 according to the invention allow the connection of a vent valve.
