The device has a rupture of a thermal bridge comprising means of a reduction of the differential expansion between an outer body and a body inside which associates

摘要

The device has a connection unit (4) for breaking a thermal bridge between inner and outer bodies (2, 3). A reinforcement unit (7) is connected to the outer or inner body by a rigid connection. The reinforcement unit is made up of steel having an elasticity coefficient and an expansion coefficient different from that of aluminum used to fabricate sections (5, 6) of inner and outer bodies of the device.
