  Distanzstück für Kühlrippen von Wärmeaustauschern und Verfahren zur Herstellung desselben 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 
 EMI2.1 
 Blechteile am Lochumfang, Stauchen der so erhaltenen niedrigen, zylinderartigen Kragen und Stanzen der Blechränder, wogegen man gemäss Fig. 6 von einem stärkeren Blech ausgeht, aus welchem durch Lochen, Kaltfliesspressen und Stanzen die dargestellte Bauart erzeugt wird. 



   Bei den bekannten Konstruktionen mochte es vorkommen, dass die Passung der Distanzringe an die zugeordneten Leitungsrohre ungenau bzw. locker ausgefallen   ist, wodurchsich eine unzulängliche   Wärmeabgabe ergab. Auf Grund der ausgleichenden Wirkung der Stege kann nun ein solcher Mangel nicht mehr vorkommen. Durch die zusätzliche Wärmeleitung durch die Stege in den erfindungsgemässen Distanzstücken wird der Wirkungsgrad des Wärmeaustausches besonders bei den   zumeist verwendeten Luftströmun-   gen mittlerer und grösserer Stärke bedeutend erhöht. 



    PATENTANSPRÜCHE :    
1. Distanzstück für Kühlrippen von Wärmeaustauschern, das zwischen diesen Kühlrippen angeordnet ist,   gekennzeichnet durch   einen durch mehrere in einer Reihe angeordnete Öffnungen (2) durchbrochenen Blechstreifen   (1),   in welchem der Durchmesser der Öffnungen (2) mit dem Aussendurchmesser der Leitungsrohre des Austauschers und der Abstand zwischen den einzelnen Öffnungen mit dem Abstand der einzelnen Leitungsrohre voneinander gleich ist.

 EMI2.1
 Sheet metal parts on the circumference of the hole, upsetting the low, cylinder-like collars obtained in this way and punching the sheet metal edges, whereas according to FIG. 6, a thicker sheet metal is assumed from which the design shown is produced by punching, cold extrusion and punching.



   In the known constructions, it may happen that the fit of the spacer rings to the associated conduit has turned out to be imprecise or loose, resulting in inadequate heat dissipation. Due to the compensating effect of the webs, such a defect can no longer occur. Due to the additional heat conduction through the webs in the spacers according to the invention, the efficiency of the heat exchange is significantly increased, especially with the mostly used air currents of medium and greater strength.



    PATENT CLAIMS:
1. Spacer for cooling fins of heat exchangers, which is arranged between these cooling fins, characterized by a sheet metal strip (1) perforated by several openings (2) arranged in a row, in which the diameter of the openings (2) corresponds to the outer diameter of the pipes of the exchanger and the distance between the individual openings is the same as the distance between the individual conduits.

Claims (1)

2. Verfahren zur Herstellung eines Distanzstückes nach Anspruch l, dadurch gekennzeichnet, dass das Distanzstück aus Blech durch Lochen, Ausranden, Stauchen und Stanzen bzw. durch Lochen, Kaltfliesspressen und Stanzen hergestellt wird (Fig. 5 und 6). 2. A method for producing a spacer according to claim l, characterized in that the spacer is made from sheet metal by punching, edging, upsetting and punching or by punching, cold extrusion and punching (Fig. 5 and 6).
