Abstract
The present invention provides a regenerator having magneto caloric material (MCM) configured with flow channels for the passage of a heat transfer fluid through the MCM. The flow channels are created by positioning elongate elements of the MCM adjacent to each other. The elongate elements provide surface area necessary for heat transfer while the flow channels reduce the pressure drop incurred by the heat transfer fluid as it flows through the regenerator. The elongate elements can also be configured with MCM having different Curie temperatures (e.g., different Curie temperature ranges) in order to accommodate a variety of ambient conditions in which the regenerator may be used.
