Device for generating cold and heat by a magneto-calorific effect

A device for continuously generating cold and heat by a magnetic effect. The device includes a magnetic field generator, which is arranged in at least one crown segment and defines an annular space crossed by a circular coaxial part provided with radial transverse cavities and contains at least one type of magneto-calorific material. The inventive device also includes a circulating pump for axially supplying a heat carrier to the cavities. A first collector picks up the heat carrier, which passes through the radial cavities in the area containing the magnetic field generator, and a second collector picks up the heat carrier which passes through the radial cavities in an area located outside of the magnetic field generator.
