Abstract
A composite fiber capillary structure includes a first interlacing layer and a second interlacing layer. The first interlacing layer is formed as a hollow cylindrical net structure by metal wires with a first diameter. The second interlacing layer is also formed as a hollow cylindrical net structure by metal wires with a second diameter. The first diameter is larger than the second diameter, and the second interlacing layer covers the first interlacing layer in a sleeving manner. In addition, a fabricating method of the composite fiber capillary structure and a heat pipe with the composite fiber capillary structure are also provided.
