ABSTRACT:
The invention relates to a dryer for objects, in particular for motor vehicle bodies (1). Known dryers comprise a drying tunnel (6), located within an insulated housing (2), a number of nozzles (25) being arranged in the lateral walls (8) of said tunnel. These nozzles are used to direct hot circulatory air against the objects (1). The circulatory air is extracted from the drying tunnel (6) by means of extraction openings (7) below the objects (1) and is supplied to two air chambers (13) located at the sides of the drying tunnel (6). The circulatory air is extracted upwards via said chambers with the help of fans (18). A heat register (26) is located in each of the two air chambers (13) and is aligned in a substantially vertical direction, said registers consisting of a number of intercommunicating pipe sections that are traversed by hot primary air and are surrounded by the circulatory air. The circulatory air that is heated in this manner is supplied to air distribution chambers (24), which are located on the pressure side of the fan (18), are adjacent to the lateral walls (8) of the drying tunnel (6) and which communicate with the internal chamber of the drying tunnel (6) by means of the nozzles (25).
