description The utility model relates to a vehicle permanent-magnet retarder rotor drum with favorable heat dispersion. On the structural basis of a present retarder rotor drum, a forcing heat-sinking air duct of radiation vanes is additionally arranged, which changes the state of fluid in the rotor drum, increases the disturbance of airflow in the air duct, increases the heat exchange rate between the rotor drum and air, and reduces the temperature rise of the rotor drum when a retarder acts, so that the braking stability of a permanent-magnet retarder is improved.
