1. A flexible heat dissipation device comprising:
a condenser;
an evaporator having at least one vapor chamber, a liquid inlet and a vapor outlet, a capillary structure and a working fluid being received in the vapor chamber, the liquid inlet and the vapor outlet being in communication with the vapor chamber;
a vapor tube, one end of the vapor tube being in communication with the vapor outlet, the other end of the vapor tube being in communication with the condenser;
a liquid tube, two ends of the liquid tube being respectively in communication with the evaporator and the condenser, whereby the evaporator, the vapor tube, the condenser and the liquid tube form a loop for the working fluid to flow through; and
at least one bellows section disposed on one or both of the vapor tube and the liquid tube, the bellows section having multiple waved stripes, one or more of heights, widths and pitches of at least one of the multiple waved stripes being unequal to a height, a width and a pitch of an adjacent one of the multiple waved stripes;
wherein the heights of the multiple waved stripes are gradually decreased from two sides of the bellows section to a middle of the bellows, so that when the bellows section is bent, the waved stripes at the middle of the bellows section will not interfere with the waved stripes on the two sides of the bellows section.
