Abstract (en)
[origin: WO03078072A1] The device for homogeneous impingement of a planar surface (2) of a tool with a heated gas comprises a nozzle plate (5) which is provided with nozzles (3) and which extends in a parallel position to the planer surface, being provided with openings for the nozzles (3). The nozzles (3) are disposed in a normal position with regard to the surface (2) which is to be impinged upon and are embodied in a tubular form. A spiral-shaped deflector device (6) is arranged therein. Since the gas jets impact upon the surface (2) to be impinged upon in a normal position, the shortest possible jet path arises and heat transition loss is reduced. Spiral shaped guidance of the jets increases the cross-sectional area upon exit, whereupon the surface (2) to be impinged upon is covered in a homogeneous manner when the nozzles (3) are arranged in a suitable manner.
