Method for molding and connecting vacuum insulating board with non-planar surface area in inner plastic wall of e.g. refrigerant housing, involves pressing vacuum panel on non-planar surface area such that panel receives surface structure

摘要

The method involves manufacturing a vacuum panel (1) as a flat plate, and pressing the vacuum panel on a non-planar surface area to be insulated such that the vacuum panel receives a surface structure (2), where the non-planar surface area is made of plastic. A flat vacuum insulating board is manufactured by using loose powder filling at loading pressure of about 1 bar. A cavity is provided between a plastic inner wall and an outer wall and foamed with polyurethane foam. The surface structure appears partially or completely on an opposite lying side of the vacuum insulating board.
