ALUMINIUM HEAT INSULATING PANEL WHEREIN BULK HEAT INSULATING MATERIALS IS FIXED TO BOTH SIDES OF ALUMINIUM RADIATION HEAT INSULATING MATERIAL WITH CONNECTING PINS, AND METHOD FOR MANUFACTURING THEREOF

摘要

PURPOSE: A aluminium heat insulating panel is provided to insulate conductive heat, convective heat and radiation heat by inserting aluminium radiation heat insulating material between two bulk heat insulating materials and fixing with connecting pins without adhesives. CONSTITUTION: The aluminium heat insulating panel has the structure wherein the bulk heat insulating materials(2b) are fixed on the both sides of aluminium radiation heat insulating material(1) with plastic connecting pins(3), and skins(5) are attched on the both sides of the bulk heat insulating materials with adhesives(4). The aluminium radiation heat insulating materials are those wherein on the both sides of reinforcing materials for molding is attached a aluminium foil with direct or indirect heat. Also, on the surface of the aluminium radiation heat insulating material are formed minute holes. The skin is one of aluminium sheet, enamel, stainless or polymetal. The plastic connecting pins are comprised of toothed members or locking members.
