MAGNETIC REFRIGERATOR

摘要

[Problem] To improve heat transport capability and heat transport efficiency and reduce the size, weight, and cost. [Solution] A magnetic body arranged plate (700) has a plurality of magnetic body units (200A, ...) each including a plurality of magnetic members (10Aa, ...) made of the same material and arranged in row at intervals. The magnetic body units (200A, ...) are arranged side by side at intervals in a direction perpendicular to the arranging direction of the magnetic members (10Aa, ...). A low-temperature side heat exchange unit and a high-temperature side heat exchange unit are disposed at one end and at the other end of each magnetic body units (200A, ...), on the magnetic body arranged plate (700), respectively. A plurality of permanent magnets and a plurality of heat conductive members facing the magnetic body arranged plate (700) are arranged on a magnet/heat conductive member arrenged plate. When the magnetic body arranged plate (700) and the magnet/heat conductive member arranged plate are moved relative to each other in the arranging direction of the magnetic body units (200A, ...) by a driving unit, the permanent magnets apply magnetism separately to the magnetic members (10Aa, ...) of each magnetic body unit (200A, ...). The magnet/heat conductive member arranged plate creates a temperature difference and conducts heat in one direction between the magnetic members of each magnetic body units (200A, ...), between the magnetic member positioned at one end of the magnetic body units (200A, ...) and the low-temperature side heat exchange unit, and between the magnetic member positioned at the other end of the magnetic body unit (200A, ...) and the high-temperature side heat exchange unit.
