  • Publication number: 20160018164
    Abstract: A heat pipe includes a metal tube and a sintered powder layer. An inner sidewall of the metal tube thereon defines a clearance area. The sintered powder layer is formed on the inner sidewall without covering the clearance area, such that the clearance area is exposed out without being covered by the sintered powder layer. Because of no sintered powder on the clearance area, the heat pipe can be bent at the clearance area without damaging the capillary structure formed by the sintered powder. The flow path of the working fluid is not interrupted or influenced, so the heat transfer efficiency can be maintained, which overcomes the decrement of the heat transfer efficiency of a bent heat pipe in the prior art.
