Title:
THIN HEAT PIPE AND METHOD OF MANUFACTURING THE HEAT PIPE
Document Type and Number:
WIPO Patent Application WO/2001/063195
Kind Code:
A1
Abstract:
A thin heat pipe capable of increasing the circulating capacity of working fluid and reducing the dependency on its gravity position and style, wherein a steam transfer pipe line part (16) is extended through a heat receiving part (11), a heat insulating part (12), and a heat radiating part (13) at their axial center part, a plurality of independent working fluid transfer pipe line parts (17) are installed on both side parts of the steam transfer pipe line part, pipe wall sides in contact with the steam transfer pipe line part (16) form open type slits (15, 20) comprising a plurality of slits, the working fluid transfer pipe line parts (17) are overlapped partly with the open type slits (15, 20), connected through connection holes (18), and communicating with the working fluid evaporating part (14) and steam condensing part (19) through the open type slits (15, 20), respectively, whereby, because the working fluid transfer pipe line parts (17) are independent of the steam transfer pipe line part (16) at the heat insulating part (12), the circulating capacity of the working fluid increases and the dependency of the heat receiving and radiating parts on the gravity position and style is improved.
