Description

Feuerfester, mit Außenrippen versehener Gitterstein für Wärmeaustauscher. Zur Erzielung von schraubenförmig gewundenen Durchgängen in Winderhitzern u. dgl. sind Hohlsteine mit schraubenförmig gewundener Öffnung bekannt. Diese Steine sind aber praktisch nicht verwendbar, weil sie nicht oder nur mit großen Schwierigkeiten herstellbar sind, zu viel Durchgangswiderstand haben und die Gitterwerkzüge nicht durchfahrbar machen.Fireproof grille with external ribs for heat exchangers. To achieve helically wound passages in hot water heaters and the like. hollow stones with a helically wound opening are known. These stones are but not practically usable because they cannot be used, or only with great difficulty can be produced, have too much volume resistance and the latticework does not make it passable.

Die Übelstände werden durch die Erfindung beseitigt, die einen Gitterstein zum Gegenstand hat, der an den Außenseiten mit derart gestalteten Leitrippen versehen ist, daß beim Zusammensetzen mehrerer solcher Steine schraubenförmig gewundene Durchgangskanäle entstehen. Diese Bauart ermöglicht durch entsprechende Bemessung der Form, Ausdehnung und Anzahl der Rippen jede Steigung zu erlangen und ein günstiges Verhältnis zwischen Wärmeaustauschfläche und Steingewicht herzustellen. Die einzelnen Kanäle haben einen geradlinigen Kern und um diesen herum gewundene, durch die Rippen gebildete Züge, wodurch eine starke Durchwirbelung und Mischung der Gase sowie eine bedeutend stärkere Wärmeabgabe erreicht wird. Dabei sind die Widerstände sehr gering, und die Kanäle können durchleuchtet und durchstoßen werden.The drawbacks are eliminated by the invention, which is a lattice stone has the object, which is provided on the outside with guide ribs designed in this way is that when assembling several such stones helically wound passage channels develop. This design enables expansion through appropriate dimensioning of the shape and number of ribs to achieve each pitch and a favorable relationship between Establish heat exchange surface and stone weight. The individual channels have one rectilinear core and threads wound around it, formed by the ribs, resulting in a strong turbulence and mixing of the gases as well as a significantly stronger one Heat release is achieved. The resistances are very low, and so are the channels can be x-rayed and pierced.

Die Herstellung der Steine ist einfach, da sie keine Höhlungen besitzen.The stones are easy to manufacture because they have no cavities.

Die Grundrißflächen der Steine sind so, daß die Steine lückenlos aneinander gesetzt werden können.The plan areas of the stones are such that the stones are seamlessly attached to each other can be set.

Bei der obersten Steinschicht sind die oberen Kanten der Leitrippen stark abgerundet (Abb. 2), so daß trichterartig erweiterte Eingänge in die Kanäle geschaffen werden, wodurch der Widerstand beim Eintritt der Gase in das Gitterwerk erheblich vermindert wird. Es ist bei Winderhitzern wünschenswert, in den oberen Lagen des Gitterwerks ein anderes Verhältnis von Steingewicht zur Heizfläche zu haben als in den unteren Lagen. Mittels des neuen Steines kann dies durch zweckentsprechende Gestaltung der Form und Abmessung der Rippen ohne Schwierigkeit erreicht und es können zwischen den Steinen in den Lagen von oben nach unten Durchgänge mit verschieden großen bzw. wechselnden Ouerschnitten und -größen geschaffen werden. Das Gitterwert: kann auch teilweise aus alten bekannten Steinen hergestellt sein.The top edges of the guide ribs are on the top stone layer strongly rounded (Fig. 2), so that funnel-like widened entrances into the canals created, whereby the resistance when the gases enter the latticework is significantly reduced. It is desirable in the case of hot water heaters in the upper Layers of the latticework have a different ratio of stone weight to heating surface than in the lower layers. By means of the new stone this can be achieved through appropriate Shaping the shape and dimension of the ribs achieved without difficulty and it can be between the stones in the layers from top to bottom with different passages large or changing cross-sections and sizes are created. The grid value: can also be partially made from old known stones.

Abb. i zeigt einen Stein, mit dem das Gitterwerk nach Abb. 2 hergestellt wird. Die im Grundriß kreuz- oder sternförmigen Durchgänge sind in den benachbarten Kanälen abwechselnd nach links und rechts gewunden. Abb. 3 zeigt zwei Steine, die zur Herstellung des Gitterwerkes nach Abb. .1 dienen, das gleichfalls rechts- und linksgewundene Durchlässe hat.Fig. I shows a stone with which the latticework according to Fig. 2 is made will. The cross-shaped or star-shaped passages in plan are in the neighboring ones Channels wound alternately to the left and right. Fig. 3 shows two stones that serve to produce the latticework according to Fig. 1, which is also right and has left-handed passages.
