Abstract
A heat pipe structure includes a first tubular body and a second tubular body. The first tubular body has a first receiving space. A first working fluid is contained in the first receiving space. The second tubular body is disposed in the first receiving space. The second tubular body has a second receiving space. A second working fluid is contained in the second receiving space. The solidification temperature of the first working fluid is different from the solidification temperature of the second working fluid so that the heat pipe structure can be activated at low temperature to keep operating at normal temperature to enhance the performance. Moreover, the assembly applicability is enhanced to lower the assembling cost.
