<p>An industrial tunnel oven for the heat treatment of parts (15), such as motor vehicles bodies and the like, comprises at least one outer wall (11, 111, 211, 311) and preferably also an inner wall (17, 117, 217, 317) for defining a tunnel (12) through which the parts pass. Air is introduced into the tunnel by means of openings (18, 118, 218, 318) for emitting hot air inside the tunnel. The outer wall has a substantially cylindrical form, except, where required, in a base zone, and interspaces are defined therewith for circulation of the hot air towards the said outlet openings (18, 118, 218, 318) and/or towards a hot-air evacuation path</p> |
