Definitions

  • the invention relates to a device for tempering workpieces, in particular for drying vehicle bodies, with a) a housing; b) a tempering tunnel housed in the housing; c) a tempering for tempering the workpieces.
  • the invention relates to a system and a method for tempering workpieces.
  • tempered air is understood to be one which has the temperature required for temperature control of the vehicle body. The same applies generally to workpieces of all kinds.

  • Vehicle bodies have recently become increasingly complicated in structure. In particular, they have different masses in different areas. For example, the lowermost area, the sill area or the floor area, is heavily massed and therefore has a considerable heat capacity. When heating the various areas of the vehicle body, it takes a considerable time until the heat has completely penetrated these areas. In addition, this time differs locally, depending on how the distribution of mass and the distribution of heat capacities are in the respective area.
  • the B-pillar or areas on the roof rails are further examples of areas of a vehicle body, which specify different heat capacities and make different demands on a drying process.

Abstract

L'invention concerne un dispositif servant à réguler la température de pièces (16), en particulier pour le séchage de carrosseries de véhicule (18), comportant un boîtier (20), un tunnel de régulation thermique (22) monté dans le boîtier (20), et un système de régulation thermique (86, 94) servant à réguler la température des pièces (16). Le système de régulation thermique (86, 94) comprend un dispositif de régulation thermique intégrale (86) qui permet de réguler une pièce en totalité, et un dispositif de régulation thermique locale (94) qui permet de réguler de manière ciblée la température de parties localement délimitées (18a, 18b, 18c) des pièces (16) et qui comprend à cette fin plusieurs unités de régulation thermique (96) pouvant être activées et commandées indépendamment les unes des autres. Le dispositif de régulation thermique intégrale (86) et le dispositif de régulation thermique locale (94) sont agencés dans le tunnel de régulation thermique (22) de telle manière qu'une pièce (16) peut, au moins dans une section active (98) dans le tunnel de régulation thermique (22), se trouver soumise à la fois à l'action du dispositif de régulation thermique intégrale (86) et à l'action du dispositif de régulation thermique locale (94). L'invention concerne en outre un système (14) et un procédé permettant de réguler la température de pièces (16).
