Title:
THIN PLATE-TYPE HEAT PIPE USING PIPE BODY AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/221938
Kind Code:
A1
Abstract:
Provided in the present invention are a thin plate-type heat pipe using a pipe body and a method for manufacturing same, comprising the steps of: manufacturing a circular pipe by cutting a metal pipe material; press-processing the circular pipe while a moving frame is inserted into the circular pipe to form a plurality of protrusions on the inner surface of the circular pipe, so as to form a throttle way between the plurality of protrusions; forming a wick space by press-processing the circular pipe while the moving frame is inserted into the circular pipe; arranging, in the wick space, a fiber wick comprising aramid fiber which has been reformed to be hydrophilic; forming a housing by closing the two ends of the circular pipe while the fiber wick is arranged; and injecting, into the housing, a working fluid flowing through the throttle way through an injection port, rendering the inside of the housing into a vacuum state through the injection port, and then sealing the injection port.
