Abstract
A discoid cold cartridge filled with a latent heat storage medium, is formed from at least two parts joined together, of which one part includes the discoid main wall facing the scraper and stirrer tool and the other part of a trough-shaped base. The discoid main wall serving to act together with the scraper and stirrer tool has an inherently stable, curved shape and at least one wall of the base is reversibly adaptable to the change in volume of the latent heat storage medium in phase transition.
