Document Type and Number:
WIPO Patent Application WO/2011/139005
Kind Code:
A1
Abstract:
The present invention relates to a heat pipe production method comprising: a tubular member preparation step involving the preparation of a tubular member in the shape of a tube formed with space on the inside; a mould preparation step involving the preparation of a mould provided with an inner space having a volume corresponding to the volume of the tubular member, and with at least one escape space having a predetermined volume added to the inner space; a moulding preparation step in which the tubular member is disposed in the inner space of the mould; a compression moulding step in which pressure is applied to the empty space on the inside of the tubular member, from the ends on both sides of the same, such that one part of the tubular member is expansion moulded into the escape space and a contact joint is formed; a sintering step in which, after the tubular member that has undergone the compression step has been released from the mould, a sintered body of a metal powder is formed on the inside wall of the tubular member; and a sealing step in which a work fluid is injected into the tubular member on which the sintered body has been formed, a vacuum state is created, and the inner space is sealed.
