Abstract:
Heat-radiating module structure comprising:a heat-radiating module formed with locating sockets corresponding to locating thread holes of a circuit board on which a heat source is mounted, a center of the bottom of the locating socket being formed with a restricting thread hole;a resilient member disposed in the locating socket of the heat-radiating module, a bottom end of the resilient member being fitted around the restricting thread hole; anda fastening bolt, one end of the fastening bolt being formed with a restricting cap, the other end of the fastening bolt being formed a first screw section having slightly larger outer diameter and a second screw section under the first screw section, the first screw section being able to be screwed into/unscrewed out of the restricting thread hole, the second screw section being able to be screwed into the locating thread hole of the circuit board, the fastening bolt being fitted into the resilient member and screwed through the restricting thread hole of the heat-radiating module, whereby by means of the outer thread of the first screw section and the inner thread of the restricting thread hole, when the second screw section is unscrewed from the locating thread hole, the first screw section abuts against a lower side of the restricting thread hole and is stopped thereby so as to prevent the fastening bolt and the resilient member from bounding away.
