Abstract (en)
The assembly has an interior housing (8) formed fluid-tightly and defining flow paths (10) for conveying a fluid. An insulating layer (16) thermally surrounds the interior housing at an external side. An external housing (14) externally and sportingly surrounds the insulating layer, and is made of metal. The interior housing is manufactured as an injection molding part, and is made of a composite material i.e. fiber-reinforced plastic. A support element (18) is arranged between interior and external housings, and transmits load from the interior housing to the external housing.
