Magnetic cooling device and cooling cycle apparatus including the same

A cooling cycle apparatus comprising:

• a first heat exchanger configured to discharge heat;
• a second heat exchanger configured to absorb heat;
• and
• a magnetic cooling device disposed between the first heat exchanger and the second heat exchanger and configured to operate by sequentially switching between a first mode and a second mode,
• wherein the magnetic cooling device includes:
• a magnetocaloric material configured to allow a heat transfer fluid therethrough;
• a magnet configured to form a magnetic field around the magnetocaloric material;
• and
• a current generating device disposed adjacent to the magnetocaloric material and configured to generate a current,
• wherein in the first mode, the magnet is configured to approach the magnetocaloric material, and the current generating device is configured to generate a current in a first direction to cause the heat transfer fluid having an increased temperature to flow toward the first heat exchanger, and
• wherein in the second mode, the magnet is configured to move away from the magnetocaloric material, and the current generating device is configured to generate a current in a second direction to cause the heat transfer fluid having a decreased temperature to flow toward the second heat exchanger.
