Abstract: An active heat-radiating structure attached to a passive heat-radiating part comprises a fan, an outer frame, and two mounting members. The outer frame comprises two first connecting portions arranged at two opposite sides of the outer frame, the two mounting members are disposed on the passive heat-radiating part and connected with the outer frame. Each mounting member is provided with a first mounting portion connected with one first connecting portion. Further, each first connecting portion comprises a track provided with a plurality of positioning points and a guide groove disposed in parallel with the track, and each first mounting portion comprises at least one elastic sheet stressed to move on the track and limited by the positioning point, and a guide block stressed to slide in the guide groove. The position of the fan is adjusted by the two first connecting portions and the two first mounting portions.

Abstract: A liquid-cooled heat sink includes a heat absorption module having a liquid storage container with one heat conductive side, a liquid inlet and a liquid; a liquid transport module including one inlet tube having a first end connected spatially with the liquid inlet of the storage container and a second end connected spatially with a pump unit, and an outlet tube having a first end connected spatially with the liquid outlet of the storage container and a second end connected spatially with a storage chamber; and a heat exchange module including a fin assembly, one connection passage extending through the fin assembly and one fan unit disposed on the fin assembly, which has two opposite ends respectively connected to the pump unit and the storage chamber, the connection passage having two opposite ends respectively connected to the pump unit and the liquid storage chamber.
