Abstract

A thermally insulated housing has a substantially vacuum-tight outer shell and an at least substantially vacuum-tight inner enclosure that is spaced apart from the outer shell. The elements are connected to one another in a vacuum-tight fashion by a connection section that is at least approximately U-shaped in cross section and which is secured by its section limbs to the outer shell on the one hand and to the inner enclosure on the other by welding. A point of connection of the limbs of the U-shaped connection section to the outer shell or to the inner enclosure is thickened. The thickened area has at least essentially the thickness of material of the inner enclosure or of the outer shell.
