Abstract

Kühlrohr für einen Plasma-Lichtbogenbrenner, bestehend aus einem hohlzylindrischen Elektrodenkörper mit einer zentralen Innenbohrung, an deren vorderen Ende ein Elektrodenkernhalter mit einem dort eingesetzten Elektrodenkern angeordnet ist, und einem abdichtend in die Innenbohrung eingesetzten, hohlzylindrischen Kühlrohr, welches in seiner Innenbohrung einen als Vorlauf ausgebildeten Kühlkanal und im Zwischenraum zwischen seinem Außenumfang und dem Innenumfang des Elektrodenkörpers einen als Rücklauf ausgebildeten Kühlkanal ausbildet, wobei das Kühlrohr an seiner dem Elektrodenkernhalter zugewandten Innenseite abstandshaltende Mittel (z.B. eine Abstandsscheibe oder Drähte oder Stäbe) aufweist, die zur stirnseitigen Anlage am Elektrodenkernhalter geeignet sind.
