Abstract
A flexible heat dissipation device includes an evaporator, a vapor tube, a liquid tube and a condenser. The evaporator has at least one vapor chamber. A capillary structure and a working fluid are received in the vapor chamber. Two ends of the vapor tube is respectively in communication with one end of the evaporator and the condenser. Two ends of the liquid tube are 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. At least one bellows section is disposed on one or both of the vapor tube and the liquid tube. The bellows section has multiple waved stripes. More than one of the heights, widths and pitches of the multiple waved stripes are equal to or unequal to each other.
