Description

Gegenstand der Eriiindueg ist :eine, luftgekühlte: Eldktränentöhra;-welche dadurch gekennzeichnet ist;, daß die Wandung _ eines die vakuumdichte Einschmelzung der Elektro,d@enanschlüs.se umgebenden Raumes mit Durchbrechungen 'versehen ist, durch welche Kühlluft zur Umspülung :der Anschlüsse hindurchströmt.-Inder Fg., r ist eine solche Elektronenröhre in ihren hier interessierenden wesentlichen Teilen dargestellt: Der in der Fig. i teilweise wiedergegebene Anodenzylinider i ist mit Kühlrippen versehen-, von denen in der Fi;g. ii nur die Rippen :2 und 3 wiedergegeben sind. Diese Kühlrippen werden von einem Mantel q. umschlossen, welcher mit Vorsprüngen zur Halterung und Führung :der- Elektronenröhre versehen-.ist. Mittels eines angeschärften Kupferringes 5 ist auf den Anodenzylinder i die Gefäßwand 6 aus Glas vakuumdicht.. aufgesetzt, welche wiederum mittels eines angeschärftenKupferringes 7 mit dem sog. Gitterteller 8 vakuumdicht verbunden ist. Letzterer trägt Iden hier nicht :gezeigten, in den Anodenzylinder i hineinragenden Gitteraufbau, der-Elektronenröhre. Durch einen weiteren .arigeschärften Kupferring g ist,die Glashaube io mit Odem Gitterteller 8 vakuumdicht verbunden. In die Glashaube io sind Anschlußibolzen i r und. 12 vakuumdicht eingeschmolzen, welche an ihren nicht gezeigten Enden und einem dritten Auf ltager :den ebenfalls -nicht dargestellten Kathodenaufbau der Elektronenröhre halten. Über biegsame MetallBlähder i3 und 14. stehen die Anschlußbolzen vi und 12 mit den Anschlußstiftenti5 und 16 in Verbindung, welche in einer Keramikplatte 17 ruhen.;De Keramikplatte 17 wird von der Wandung des in den Gitterteller 8 eingeschraubten Bauteiles @18 gehalten. Über das Bauteil 18 ist :ein Gitterring -iig nach Art :einer Überwurfmutter geschraubt, bis dieser Gitterring ig auf dem Gitterteller 8 ruht. Die Wandung dies Bauteiles 1r8, welche einen die vakuumdichte Einschmelzung der Elektrodenanschlüsse umgebenden- Raum umschließt, weisst zahlreiche, auf ihrem (Umfang ver= teilte Durchbrechungen, z. B. -2a @und-2i, -auf, durch welche die zur Kühlung der Elekträdenansc'hlüsse dienende Luft hindurchströmt. Ziese. Kühlluft wird von einem Gebläse geliefert, welche unterhalb der Elektronenröhre den Anodenzylinder r und die schon erwähnten Kühlrippen umspült sowie an dem in der Fig. i gezeigten Teil der Elektronenröhre hochsteigt. Ein Teil dieser Kühlluft strömt dann durch in der Fig. 2 im einzelnen dargestellte, an der Unterseite des Gitterringes ig vorgesehene Ausnehmungen 2z und durch die Durchbrechun@gen, z. B. 2o und 2i, in der Wandung des Bauteiles 18 um die Elektradenanschlüsse herum; von dort aus gelangt sie durch Durchbrechungen; z. B. 2 1 2.4 und 25, in der Keramikplatte ,17 nach außen. In die Fig. i sind derart verlaufende Strömungslinien eingatragen. Wie die Fig:2 erkennen läßt, sind die schon erwähnten Ausnehmungen 22 gleichmäßig an der Unterseite des Gitterringes ig verteilt, so da.ß die Kühlluft allseitig in,den von :der Wandung des Bauteilesi,i8 umgebenen Raum eindringen kann.The subject of the invention is: an, air-cooled: Eldktränentöhra; - which is characterized by the fact that the wall of a space surrounding the vacuum-tight melting of the electrical and d In FIG. 1, such an electron tube is shown in its essential parts that are of interest here: The anode cylinder i, partially shown in FIG. ii only the ribs: 2 and 3 are shown. These cooling fins are covered by a jacket q. enclosed, which is provided with projections for holding and guiding: the electron tube. By means of a sharpened copper ring 5, the vessel wall 6 made of glass is placed on the anode cylinder i in a vacuum-tight manner. The latter does not have the Iden here: the lattice structure shown protruding into the anode cylinder i, the electron tube. The glass hood io is connected to the Odem grid plate 8 in a vacuum-tight manner by a further .arigeschärften copper ring g. In the glass hood io there are connecting bolts ir and. 12 vacuum-tight, which at their ends (not shown) and a third support: hold the cathode structure of the electron tube, which is also not shown. The connecting bolts vi and 12 are connected to the connecting pins ti5 and 16 via flexible metal blades i3 and 14, which rest in a ceramic plate 17. The ceramic plate 17 is held by the wall of the component @ 18 screwed into the grid plate 8. About the component 18 is: a lattice ring -iig of the type: a union nut screwed until this lattice ring ig rests on the lattice plate 8. The wall of this component 1r8, which encloses a space surrounding the vacuum-tight seal of the electrode connections, has numerous perforations distributed on its circumference, e.g. -2a @ and-2i, through which the for cooling the Air serving for electrical connections flows through it. Cooling air is supplied by a fan, which flows around the anode cylinder r and the cooling fins already mentioned below the electron tube and rises up the part of the electron tube shown in FIG. 1. Part of this cooling air then flows through In Fig. 2 shown in detail, on the underside of the grid ring ig provided recesses 2z and through the perforations, z. B. 2o and 2i, in the wall of the component 18 around the electrade connections; from there it passes through Breakthroughs, e.g. 2 1 2.4 and 25, in the ceramic plate, 17 to the outside. Flow lines running in this way are entered in FIG. 1. As can be seen in FIG. the already mentioned recesses 22 are evenly distributed on the underside of the grille ring, so that the cooling air can penetrate on all sides into the space surrounded by the wall of the component.
