Description

Die vorliegende Erfindung bezieht sich auf Wärmeaustauscher, insbesondere Heizkörperglieder, die im zusammengebauten Zustand senkrechte, mit Flossen oder Rippen besetzte Luftheizkanäle bilden.The present invention relates to heat exchangers, in particular Radiator members that are vertical when assembled, with fins or Form air heating channels occupied by ribs.

Erfindungsgemäß sind an den lotrechten Rändern der Heizkörperglieder durchgehende Querrippen und an den Stirnflächen Heizflossen oder Rippen angeordnet. Nach dem Zusammenbau bilden je zwei Glieder mit den durchgehenden Querrippen einen seitlich geschlossenen, oben und unten offenen Luftkanal. Die Naben mit den Ein- und Austrittsöffnungen für das Heizmittel werden dabei zweckmäßig außerhalb des Luftkanales angeordnet, um den freien Luftquerschnitt im Kanal nicht zu verengen. Über den Luftaustrittsmündungen wird ferner zweckmäßig eine aufrollbare Decke oder ähnliches angebracht, mittels deren die Luftheizkanäle abgeschlossen bzw. der Luftstrom gedrosselt werden können.According to the invention are on the vertical edges of the radiator members continuous transverse ribs and heating fins or ribs arranged on the end faces. After assembly, each two links with the continuous transverse ribs form one Laterally closed air duct open at the top and bottom. The hubs with the and outlet openings for the heating medium are expediently outside the Air duct arranged so as not to narrow the free air cross-section in the duct. Furthermore, a rollable cover or is expediently over the air outlet openings similar attached, by means of which the air heating ducts completed or the air flow can be throttled.

Gegenüber den bekannten Heizkörpern wird durch die mit Flossen oder Rippen besetzten Kanalwände, bei gleichen äußeren Abmessungen, eine Vergrößerung der Heizkörperoberfläche erzielt. Ferner erhält man durch die Flossen- bzw. Rippenanordnung sowie durch die Schornsteinwirkung der Luftkanäle einen besonders hohen Wärmeübergang von der Heizkörperwandung an die zu erwärmende Luft. Durch die Abdeckung einiger oder aller Luftkanäle kann, auch bei konstanter Heizmitteltemperatur, wegen der starken Abhängigkeit der Heiz'körperleistung von der Luftgeschwindigkeit an der flossenbesetzten Kanalheizflächt eine weitgehende Regelung dieser Heizkörperleistung erreicht werden.Compared to the known radiators is by the with fins or Ribbed canal walls, with the same external dimensions, an enlargement the radiator surface achieved. The fin or rib arrangement also provides as well as a particularly high heat transfer due to the chimney effect of the air ducts from the radiator wall to the air to be heated. By covering some or all air ducts can, even with a constant heating medium temperature, because of the strong dependence of the radiator output on the air speed at the Fins-fitted duct heating area largely regulate this radiator output can be achieved.

In der Zeichnung ist ein Ausführungsbeispiel eines Heizkörpers gemäß vorliegender Erfindung dargestellt.In the drawing, an embodiment of a radiator is according to Present invention illustrated.

Abb. i zeigt die Seitenansicht, Abb.2 den Querschnitt eines solchen Heizkörpergliedes; Abb.3 stellt die Draufsicht zusammengebauter Heizkörperglieder dar.Fig. I shows the side view, Fig.2 shows the cross section of such Radiator member; Figure 3 shows the top view of assembled radiator sections represent.

Durch die äußeren durchgehenden Querrippen a an den Heizkörpergliedern werden im zusammengebautenZustand zwischen je zweiGliedern seitlich geschlossene Kanäle b gebildet. Für die Kanalbildung können z. B. auch an Stelle der angegossenen durchgehenden Querrippen gegen die Heizkörperglieder gepreßte oder in Nuten eingezogene Blechstreifen vorgesehen sein. Durch diese Kanäle muß die zu erwärmende Luft, infolge des natürlichen Auftriebes, mit erheblicher Geschwindigkeit von unten nach oben strömen. Kanalseitig angeordnete Flossen bzw. Rippen c vergrößern die Heizfläche und erhöhen ferner durch ihre besondere Anordnung den Wärmeaustausch. Das Heizmittel wird durch oben und unten angeordnete seitliche Naben d den einzelnen Gliedern gemeinsam zugeführt und entnommen.Through the outer continuous transverse ribs a on the radiator members are closed laterally between two links in the assembled state Channels b formed. For the channel formation z. B. also in place of the cast continuous transverse ribs pressed against the radiator members or drawn into grooves Sheet metal strips can be provided. Through these channels, the air to be heated, as a result of natural buoyancy, from bottom to top with considerable speed stream. Fins or ribs c arranged on the channel side increase the heating surface and also increase the heat exchange due to their special arrangement. The heating medium is shared by the individual links through lateral hubs d arranged above and below fed and removed.

Abb.4 zeigt einen schematischen Längsschnitt durch einen zusammengebauten Heizkörper. Durch die aufrolllrare Decke e oder ähnlich wirkende Absperrungen können einzelne oder alle Luftkanäle b albgedeckt werden, wodurch die Wärmeabgabe des Heizkörpers auch bei 'konstanter Heizmitteltemperatur geregelt werden kann, denn nach Abdeckung der Kanäle kann durch die Außenheizfläche (Strahlungsheizfläche) nur noch ein Bruchteil der Gesamtwärmeleistung abgegeben werden.Fig.4 shows a schematic longitudinal section through an assembled Radiator. The roll-up ceiling or similar barriers can be used individual or all air ducts are b albcovered, whereby the heat dissipation of the radiator can be regulated even at 'constant heating medium temperature, because after cover of the ducts can only be reduced to a fraction by the external heating surface (radiant heating surface) the total heat output.
