摘要： Continuous ovens are known including heat radiators, especially electrical infrared radiators for the thermal treatment of thin, plate-like components, especially printed circuit boards fitted with electronic components, including a conveying device which has two spaced-apart, parallel, synchronously driven continuous drive bands each having support elements for the plate-like components. In order to make a continuous oven including a conveying device wherein the printed circuit boards to be soldered are carried through the oven on a defined plane in their entire structural length such that the structural changes involved do not strongly affect the thermal conditions in the oven, an auxiliary drive band is disposed between the two drive bands and parallel thereto. If necessary, the auxiliary drive band is equipped with projections directed vertically to the band plane of the band which is created by the drive bands and the length of which does not surpass the support surface for the plate-like components formed by the support elements.

摘要： Continuous ovens are known for soldering electronic components on circuit boards, with a conveyor belt having supports for the circuit boards, and having infrared radiators disposed in a spaced-apart relationship along the conveyor belt above and/or below the plane of belt movement, which are associated with at least one preheating zone and, following this zone in the direction of movement of the belt, with a soldering zone. To develop a continuous oven such that the temperatures between large and small components to be soldered on circuit board will be nearer one another in the soldering zone than in conventional ovens, a cooling zone is disposed between the preheating zone and the soldering zone, in which a forced cooling is performed with a gaseous coolant which is driven by a blower through nozzles disposed in the cooling zone substantially perpendicularly to the plane of the conveyor belt.

摘要： Disclosed is a self-contained radiant unit in the form of a portal for use particularly as a drying and baking tunnel for the automobile industry which is equipped with a plurality of infrared lamps on its inner surfaces. Air inlet openings are provided in the roof and/or side walls of the portal, at least over the region midway along with their horizontal extension, for the turbulence-free removal of the vapors emanating from the surface of the object being treated as well as of suspended particles present in the drying and baking zone.
