ABSTRACT:
An air-conditioning element includes ducts, through which gaseous or liquid media are passed for cooling or heating. The air-conditioning element is constructed as a solid metal sandwich with a light core of corrugated aluminum and covering layers of smooth aluminum strip. The media guides are formed between the corrugated aluminum and the covering layers, and the media guides are connected with one another by way of the ducts. A method for the production of the air-conditioning element includes the steps of joining together at a joint a stack of two covering layers and a core of corrugated aluminum, which is disposed between the covering layers, by hot rolling, adhesives, lacquers or other adhesion promoters that have been previously brought into the regions of the joint; and after the stack has cooled, milling a duct in a perpendicular direction to the course of the corrugations, and then closing off the open sections of the duct by a metal strip.
