Definitions

  • the subject of the present invention is a ventilation and cooling device for a cassette supporting at least one transmitter, in particular UV, said transmitter being in the form of a rod placed substantially at the focus of a reflector consisting of a part of two longitudinal reflective walls arranged opposite and the other part of a longitudinal reflecting shield partially masking the junction between two walls of the same reflector, the neighboring walls of two contiguous reflectors joining in a sector in V.
  • Cassettes of this type generally have a thickness close to 200 mm.
  • Ventilation is ensured by a conventional fan placed on the back of the cassette.
  • the cassettes cannot have a thickness greater than approximately 65 mm. Such a thickness no longer allows the use of a fan which, in any event, would cool only a small part of the elements of the cassette.
  • the ventilation can be further optimized.
  • the cassette generally referenced (1), essentially comprises a frame (2) and a cover (3).
  • ventilation and cooling are provided by a plurality of perforated tubes (7), mutually parallel and parallel to the rods.
  • These tubes can be of any section, for example cane, circular, rectangular, oval, etc.
  • the ventilation between the shield and the reflector also has the function of maintaining an anti-pollution pressure above the treated products.
  • the ventilation in the tubes (7) will be pressurized with adjustable flow rates, cane by cane.
  • the air from the rods comes from a support ramp, not shown, and is evacuated on the radiating face of the cassette as on the back of the latter.
  • the air is then taken upstream and downstream of said cassette by usual extraction means (2) to be evacuated or recycled.

Claims (5)

  1. Lüftungs- und Kühleinrichtung für einen Gehäuseträger mit zumindest einem rohrförmigen Strahler, insbesondere UV, welcher in etwa im Brennpunkt eines Reflektors angeordnet ist, der einerseits aus zwei in Längsrichtung einander gegenüberliegend angeordneten reflektierenden Wänden und andererseits aus einer länglichen Abschirmung besteht, die teilweise den Raum zwischen den beiden einen Reflektor bildenden Wänden reflektierend abdeckt, wobei die benachbarten Wände von zwei aneinanderstoßenden Reflektoren mit einem V-förmigen Bereich zusammentreffen, dadurch gekennzeichnet, daß sie aus einem gelochten Rohr (7) zum Zuführen von Kühlluft oder mehreren davon besteht, welche an ihren jeweiligen Enden mit Verteiler bildenden Rampen verbunden sind, daß das Rohr oder die Rohre in etwa prallel mit dem Strahler oder den Strahlern verlaufen und außerhalb der Reflektoren (5) angeordnet sind und ihre Achsen im wesentlichen in derselben Ebene wie die Rohre der Strahler liegen.
  2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß das Rohr (7) zueinander und zu den Rohren der Strahler (4) parallel verlaufen.
  3. Einrichtung nach einem der Ansprüche 1 und 2, dadurch gekennzeichnet, daß die Rohre einen quadratischen, kreisförmigen, rechteckigen oder ovalen Querschnitt haben.
  4. Einrichtung nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß der Luftstrom stattfindet:
    - zwischen der Abschirmung und dem entsprechenden Reflektor, um den Strahler von oben her zu umspülen;
    - an der äußeren Basis der Reflektoren, die zu diesem Zweck mit Durchbrüchen versehen sind, zum Beispiel am First (8) oder der Basis (9) des Reflektors für die in Längsrichtung verlaufenden, seitlichen Bereiche;
    - durch die Abdeckung (3) hindurch aufgrund in dieser vorgesehener Durchlässe (10).
  5. Vorrichtung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß die Ventilation in den Rohren (7) pro Rohr einstellbar mit Überdruck erfolgt.
