1. A magnetic refrigeration system configured to transport heat from a low-temperature-side heat exchanger toward a high-temperature-side heat exchanger, the magnetic refrigeration system comprising:
a plurality of heat transporters, each of the heat transporters being configured to be switched between a heat-generating state and a heat-absorbing state in response to magnetic field application and cancellation of the magnetic field application, the plurality of heat transporters being arranged between the low-temperature-side heat exchanger and the high-temperature-side heat exchanger;
a magnetic field application unit configured to apply a magnetic field to the plurality of heat transporters so that a heat transporter of the heat transports to which a magnetic field is applied and a heat transporter of the heat transporters to which a magnetic field is not applied are alternately arranged in a heat transport direction from the low-temperature-side heat exchanger toward the high-temperature-side heat exchanger; and
a drive mechanism configured to periodically move at least the plurality of heat transporters
so that a heat transporter to which the magnetic field is applied by the magnetic field application unit is periodically switched and
so that a state of thermal contact among the low-temperature-side heat exchanger, the plurality of heat transporters, and the high-temperature-side heat exchanger is periodically switched,
an end portion of at least one heat transporter of the plurality of heat transporters, in the heat transport direction, is a heat transfer accelerator that accelerates heat transfer.
