Abstract: Heat-radiating module structure. Locating thread holes are formed on a circuit board around a heat source mounted on the circuit board. The heat-radiating module is formed with locating sockets corresponding to the locating thread holes, in which a resilient member is inlaid. The bottom of the locating socket is formed with a restricting thread hole through which a fastening bolt is screwed. When a second screw section of the fastening bolt is screwed into the locating thread hole, the resilient member is compressed to exert a resilient pressure onto and locate the heat-radiating module on the heat source under a certain pressure. When the second screw section is unscrewed from the locating thread hole, a first screw section above the second screw section abuts against a lower side of the restricting thread hole to prevent the fastening bolt and the resilient member from bounding away from the locking socket.
