Abstract
A heat pipe (100) includes a first substrate (102) including a plurality of first low fins (14) and high fins (16), and a second substrate (104) opposing the first substrate and including a plurality of second low fins (14) and high fins (16). A plurality of micro grooves (18) is formed between adjacent fins to form liquid channels (106) of the heat pipe. The first and second high fins are received in corresponding micro grooves of the heat pipe and soldered to the second and first substrates, respectively.

15. A method of making a heat pipe assembly, comprising steps of:
-
providing a continuous plate extending along a longitudinal direction;
forming a plurality of fins including low fins and high fins on one surface of the plate along a transverse direction perpendicular to said longitudinal direction wherein every adjacent two high fins are spaced from each other by more than one low fins and wherein a plurality of micro grooves are formed between every adjacent two fins, respectively;
cutting a section of said plate with a predetermined length along said longitudinal direction wherein said section includes at least one high fin;
folding said cut section to form two spaced parts opposite to each other in a vertical direction perpendicular to said longitudinal direction and said transverse direction wherein said at least one high fin, which is located one of said two parts, is retainably received in one corresponding micro groove in the other of said two parts under a condition that the low fins of said one of the two parts are spaced from the low fins of the other of the two parts in said vertical direction. - View Dependent Claims (16, 17, 18, 19)
