Abstract: A heat dissipation device has a frame assembly, a gravity loop thermosyphon, and a dissipating fin assembly. The gravity loop thermosyphon has a heat exchanger, a condenser, two bendable tubes, and working fluid. One end of each bendable tube communicates with the heat exchanger and another end of each bendable tube communicates with the condenser and thus the working fluid may circulate therein. After the bendable tubes are bent, the condenser can be moved to an appropriate location or tilted to an appropriate angle according to the environment, and then the location and the angle are fixed via the frame assembly so the gravity loop thermosyphon can adapt for different dissipation assemblies.
