Abstract

The invention relates to a method for manufacturing a flat-plate heat tube. The method comprises the following steps: (1) providing an upper cover plate and a lower cover plate; (2) providing a plurality of first metal powders, and after being sintered, the first metal powders form a plurality of supporting columns; (3) arranging one end of each of the supporting columns on the upper surface of the lower cover plate, and correspondingly, the height of each supporting column is equivalent to the distance between the corresponding positions of the upper cover plate and the lower cover plate; (4)providing a plurality of second and third metal powders, filling the bottom of the lower cover plate with the metal powders, arranging the metal powders in the way of surrounding the supporting columns, and sintering the lower cover plate at a high temperature so as to enable the second metal powders to form a first capillary structure attached to the upper surface of the lower cover plate and toenable the third metal powders to form a second capillary structure attached to the upper surface of the first capillary structure; (5) welding the supporting columns and the lower cover plate on thelower surface of the upper cover plate so as to form a rough blank; and(6) processing the rough blank by vacuum-pumping, working fluid injection, degasification, sealing and surface heat treatment, thereby obtaining the final product of the flat-plate heat tube.

Description

technical field [0001] The invention relates to a method for manufacturing a flat heat pipe, in particular to a method for manufacturing a flat heat pipe with a composite capillary structure. Background technique [0002] At present, heat pipes are commonly used in the industry to solve the high-density heat dissipation problem of high-speed computers, such as heat pipes, loop heat pipes, and flat heat pipes (Vapor Chamber) and other products. [0003] The working principle of the flat heat pipe is the same as that of the traditional heat pipe. Because it has a larger heat conduction area than the traditional heat pipe, and meets the high practical value of "light, thin, short, and small", it is widely used in electronic products with large heat dissipation surfaces. superior. [0004] like figure 1 and figure 2 As shown, a general flat heat pipe has an upper cover 100 prepared by a stamping process, a lower cover 101 matched with the upper cover 100 , and a capillary st...
