Patent DE-4214141-A1 (DE)
Title: Air flow generator esp. for cooling reflector or object radiated with UV or IR - uses air pressure source with elongated air distributor connected to it and at least one outlet opening at distributor kept at pressure of 0.06 - 1.5 bar
Inventor: STUMPE WALTER
IPC: F24C7/06
Filed: 1992-04-29
Abstract: A slot nozzle (12) of small depth and height is provided extending across at least one long side of the air distributor (10). A continuous air flow leaves this in operation. The lateral definition of the nozzle merges at one of the two nozzle longitudinal sides, in a continuous edge free rounding off (16) to deflect the outgoing air flow laterally laminarly outwards. A longitudinally extending air conducting surface (18) esp. the outer surface of a reflector is connected to the convex rounding off (16). This further conducts the deflected air flow, and a sucked up strengthening external air flow is created as a result. USE/ADVANTAGE - For cooling surface coated with paint or lacquer and dried using electric motor (22) driven UV or IR heater (20). Highly effective air flow build up is achieved with unit which is small and simple in design and is cost effective.
