Description
Es ist bekannt, durch Stromdurchgang erzeugte Wärme durch Verdampfen einer Kühlflüssigkeit abzuführen. Solche Anordnungen finden sich beispielsweise bei Anlassern, Nietwärmern, Widerstandsschweißmaschinen und ähnlichen Vorrichtungen. Bei dieser Art der Kühlung braucht man im Vergleich mit einer Umlaufkühlung bedeutend weniger Kühlflüssigkeit. Die Anordnung hat aber den Nachteil, daß diese Kühlflüssigkeit im Maße der Verdampfung ersetzt werden muß. Wird dies vergessen, so wird die Vorrichtung infolge Fehlens der Kühlung beschädigt.It is known to heat generated by the passage of current by evaporating a cooling liquid to dissipate. Such arrangements can be found, for example, in starters, rivet warmers, Resistance welding machines and similar devices. With this type of cooling you need in comparison with one Circulating cooling means significantly less cooling liquid. The arrangement has the disadvantage that this coolant has to be replaced as it evaporates. If this is forgotten, the device becomes as a result Lack of cooling damaged.
Nach der Erfindung soll dieser Nachteil durch eine Vorrichtung vermieden werden, die gerade die Menge des verdampften Wassers ersetzt. Vorrichtungen, die hierzu geeignet sind, sind bekannt. Eine Ausführungsform zeigt das folgende Beispiel, das eine wassergekühlte obere Elektrode eines Nietwärmers darstellt.According to the invention, this disadvantage is to be avoided by a device which just replaced the amount of evaporated water. Devices that are suitable for this are known. One embodiment is shown in the following example, which is a water-cooled top electrode of a rivet heater represents.
ι ist der zu erwärmende Niet, der zwischen der unteren Elektrode 2 und der oberen Elektrode 3 eingespannt ist. Die Elektrode 3 hat einen in den Behälter 4 hineinragenden Ansatz 5. Der Behälter 4 enthält die Kühlflüssigkeit. Da der Niet beim Stromdurchgang erwärmt wird, wird auch der Elektrodenhalter heiß; dadurch wird die Kühlflüssigkeit zum Verdampfen gebracht. Der Dampf kann durch die öffnung 6 entweichen. 7 ist ein Schwimmer, der bei genügendem Vorhandensein von Kühlwasser die Wasserzuleitung 8 in bekannter Weise verschließt. Sobald der Kühlwass,erspiegel unter das zulässige Maß sinkt, öffnet der Schwimmer den Wasserzufluß und verschließt ihn wieder, wenn der richtige Wasserstand erreicht ist, so daß immer die erforderliche Kühlwassermenge vorhanden sein muß. _ι is the rivet to be heated between the lower electrode 2 and the upper electrode 3 is clamped. The electrode 3 has a shoulder protruding into the container 4 5. The container 4 contains the cooling liquid. Because the rivet heats up when the current passes through becomes hot, the electrode holder also becomes hot; this causes the cooling liquid to evaporate. The steam can get through the opening 6 escape. 7 is a swimmer who, if there is enough Cooling water closes the water supply line 8 in a known manner. As soon as the cooling water, level falls below the permissible level, the float opens the water supply and closes it again when the correct water level is reached, so that always the required amount of cooling water must be available. _
Die Vorrichtung hat vor einer Umlaufkühlung noch den großen Vorteil, daß man nur einen Wasserzufluß braucht, der in Werkstätten usw. meistens verhältnismäßig leicht zu schaffen ist, während die Bereitstellung eines Wasserabflusses häufig größeren Schwierigkeiten begegnet.The device has the great advantage of a circulation cooling that you only needs a water supply, which in workshops etc. usually increases relatively easily creating is often more difficult while providing a water drain encountered.
