Patent CA-2488078-C (CA)
Inventor: VELTKAMP WESSEL BART
IPC: F25D23/06
Filed: 2004-11-18
Granted: 2012-09-25
Abstract: The invention relates to a thermal insulation panel. The panel includes a housing with a first main wall and a second main wall which each extend perpendicularly to a temperature gradient. The housing also includes auxiliary walls connecting both main walls and extending parallel to the temperature gradient.  The auxiliary walls are connected along edges to the main walls. A filling is placed in the housing and is able to withstand pressure forces. The pressure within the housing is reduced to a value at which no heat transfer of any significance takes place.  The housing is manufactured from metal. A strip of the auxiliary wall contacting edges is welded to the main wall, and a welding strip is welded onto the weld. With the mere welding of a sufficiently thin metal foil it is practically impossible to obtain a weld of sufficient quality. With a sandwich weld it is possible to obtain a sufficiently strong and reliable welded connection, even when a very thin metal foil is used as an auxiliary wall.
