Abstract: A thermal module includes a thermal conductor and at least one first magnetic element. The thermal conductor is disposed above a carrier. In addition, the thermal module may further include at least one second magnetic element or at least one magnetically susceptible element. Either the second magnetic element or the magnetically susceptible element and the first magnetic element can produce magnetic attractive force or magnetic repulsion force therebetween. By such magnetic force, the thermal conductor can be retained with respect to the carrier, thus making contact with a heat generating component.
