A composite insulating panel having an insulating foam core and a plurality of heat exchange conduit means

摘要

An insulating panel includes a first sheet, a second sheet, and a body of insulating foam between the sheets. The foam has a plurality of longitudinally extending conduits through which a heat exchange medium such as air is circulated. A barrier is used to create an enlarged void space for air circulation. The barrier is located below profile crowns to prevent foam from entering the crowns and to create additional foam-free voids below the crown. Heat transfer efficiency is increased.
