Abstract
A loop heat pipe for dissipating heat generated by a heat source includes a pipe, a first capillary structure, a second capillary structure, and a working fluid in the pipe. The pipe has a condensing section, an evaporating section adapted to contact the heat source thermally, and an obstructing section adjacent to the evaporating section. The first capillary structure on an inner surface of the pipe is disposed between the condensing section and the obstructing section. The second capillary structure has a first and a second parts connected with each other. The first part on the inner surface of the pipe is extended from the evaporating section to the obstructing section. The second part passing through the obstructing section is extended from the obstructing section to the condensing section. A space between the first capillary structure and the second part of the second capillary structure defines a compensation room.
