It is possible for magnetic heat dissipation to be separated from the protective shell, because the magnetic radiator transfers heat to the heat sink through magnetic force, and the protective shell only plays a protective role and will not affect the magnetic transmission. However, it should be noted that the material of the protective shell should have a certain thermal conductivity in order to better transfer heat, otherwise it will affect the heat dissipation effect. At the same time, it is also necessary to pay attention to maintaining good ventilation during use to ensure the best state of heat dissipation.
