Patent ID: 7543629

Claim:
A type of loop heat conducting device ( 1 ), comprising an evaporator ( 10 ) and a condenser ( 30 ) which are connected together by means of a loop pipe ( 20 ), in order to form a cyclic loop for a liquid working medium, wherein said evaporator ( 10 ) comprises a pressure-filled airtight space formed from a casing ( 11 ) and a cover section ( 12 ), said casing ( 11 ) having a bottom section and side walls, said evaporator ( 10 ) further having a wick network core ( 13 ) tightly connected to said bottom section and side walls of said casing ( 11 ), a plurality of tunnels ( 131 ) being formed on said wick network core ( 13 ), one end of the tunnels converging at a vapor chamber ( 15 ) and being connected to said loop pipe ( 20 ) to form a gaseous working medium outlet ( 21 ), another end of said loop pipe ( 20 ) passing through the condenser ( 30 ) and forming a liquid working medium inlet ( 22 ) connected to said evaporator ( 10 ), the end point ( 22 a ) of the pipe ( 20 ) extending into and coming into contact with said wick network core ( 13 ) in a compensation chamber ( 16 ) for the liquid working medium formed at the upper section of a space located between said cover section ( 12 ) and said wick network core ( 13 ), said evaporator ( 10 ) further comprises a buffer lining ( 14 ) provided along the inner side edges of said casing ( 11 ), between said wick network core ( 13 ) and said cover section ( 12 ), the surrounding edge of the cover section ( 12 ) having a corresponding protruding edge ( 121 ) that protrudes out from the inside of said casing ( 11 ) and presses against the upper part of said buffer lining ( 14 ).
