A heat pipe (<bold>10</highlight>) includes a main body (<bold>12</highlight>), an inner layer (<bold>16</highlight>), a chamber (<bold>13</highlight>) and working material (<bold>18</highlight>). The main body is made of metallic material having a high heat-transfer coefficient. The chamber is surrounded by the inner layer, and is substantially a vacuum. The working material is sealed in the chamber. The inner layer is fixed to an inner surface of the main body. The inner layer is inert to the working material, and isolates the working material from the main body. Furthermore, the working material readily globularizes when it is in contact with the inner layer.
