Abstract
A heat or cold exchanger and storage device comprises a main container of elongated configuration, divided into two chambers by a longitudinal partition and provided at either end with a perforated plate. The two chambers communicate with each other at an end opposite an inlet and outlet end, so that an cold or heat carrier medium circulates in countercurrent relationship in the two chambers. A relatively great number of elementary containers are stacked in the two chambers. These elementary containers are so shaped as to provide a free gap therebetween, when stacked, to permit the circulation of the carrier medium, and each elementary container has an air pocket therein to permit the expansion of the complete assembly. Preferably each elementary container consists of a pair of substantially semi-spherical halves providing, in their assembled condition, a gap between the self-stacking elementary containers enclosed in the main container.
