Patent ID: 7891413

Claim:
A heat pipe comprising: a shell containing a working fluid therein, the shell comprising an evaporating section, a condensing section and an adiabatic section located between the evaporating section and the condensing section; a capillary wick arranged within the shell, the capillary wick comprising a first segment, a second segment and a third segment, the first segment fully filling a whole of the evaporating section, the third segment being received in the condensing section and being connected to the first segment by the second segment; and a vapor channel defined between the second segment of the capillary wick and the shell; wherein a partition is employed between the shell at the adiabatic section and the second segment of the capillary wick, and is attached on an outer surface of the second segment of the capillary wick; and wherein a plurality of retainers are provided between the shell and the partition to retain the partition and the second segment of the capillary wick in a center of the shell.
