Abstract: The frigorie accumulator comprises a housing which defines in its interior a region for holding a frigorie storage substance such as a eutectic solution, and at least one duct which extends in a heat-exchange relationship with the housing and can contain a refrigerant fluid for removing calories from the storage substance held in the housing until it brings about freezing thereof. The housing comprises: a substantially tubular, extruded profiled section, made of a thermally conductive material, defining first heat-exchange walls between the region and the environment outside the housing, and second heat-exchange walls between the region and the refrigerant fluid contained in the duct, and a first end closure element and a second end closure element which can be connected in a fluid-tight manner to the ends of the extruded profiled section.
