Embodiment Construction

[0019] Please refer to Figure 1 to Figure 5 The flat heat pipe in the first embodiment of the present invention includes a shell 11 , a capillary structure 13 formed on the inner wall of the shell 11 , and a supporting structure 15 accommodated in the shell 11 and abutting against the capillary structure 13 . An appropriate amount of working fluid is filled in the casing 11 .

[0020] The casing 11 is formed by flattening a metal pipe body 10, so that the casing 11 is in the shape of a sealed flat plate. The capillary structure 13 is formed on the inner wall of the housing 11 by sintering. It can be understood that the above-mentioned capillary structure 13 may be other forms of capillary structures, such as wire mesh, grooves and the like.

[0021] see again Figure 4 , the above-mentioned support structure 15 is a stamped and formed metal sheet body in some embodiments, which has a certain strength to provide strong support for the capillary structure 13 and the shell 11...

Abstract

The invention relates to a flat type heat pipe, which comprises a platelike seal shell, a capillary structure formed on the inner wall of the shell and working fluid accommodated in the shell, wherein a sheeted support structure is arranged in the shell; the support structure comprises a plurality of support parts convexly arranged upwards; a through hole is formed at the top end of each support part; a channel running through from top to bottom is formed between the two adjacent support parts; the top end of each support part is butted against and is attached to the capillary structure of the wall surface on the upper side of the shell, and the bottom end of each support part is butted against and is attached to the capillary structure of the wall surface on the lower side of the shell; and the support structure is positioned in the flat type heat pipe to support upper and lower inner walls of the flat type heat pipe, so that the flat type heat pipe resists compression, is difficult to deform and damage in the using process, and has the stable performance.

Description

technical field [0001] The invention relates to a flat heat pipe and a manufacturing method thereof, in particular to a flat heat pipe with stable performance and a manufacturing method thereof. Background technique [0002] With the advancement of electronic technology, the degree of integration of electronic components is increasing day by day, and the heat generated during work is also increasing. However, the surface area of ​​electronic components tends to be smaller, and the heat flux density is increasing day by day, which is very unfavorable for the heat dissipation of electronic components. [0003] In order to quickly and efficiently disperse a large amount of heat generated by electronic components to the heat dissipation area of ​​the heat dissipation device, a flat heat pipe (vapor chamber) that uses the principle of phase change to transfer heat is a better choice. The traditional flat heat pipe has a bottom cover attached to the electronic components and a to...
