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.
