Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] figure 1 One embodiment of the invention is shown.

[0023] The flat heat pipe includes an extruded flat frame 1. The flat frame 1 includes a group of rectangular through holes 2 arranged side by side. A group of micro fins 3 are arranged on the two opposite inner walls of the through holes 2. The micro fins 3 are integrated with the flat frame 1. extruded.

[0024] The flat heat pipe of the present invention is made of metal with good thermal conductivity, especially aluminum.

[0025] figure 2 Shown is a schematic structural view of another embodiment of the present invention.

[0026] In this example and figure 1 The difference shown is that the edges and corners of the flat frame 1 are all arcs, which is not only convenient for extrusion preparation, but also convenient for transportation.

Abstract

The invention relates to the technical filed of heat exchange, in particular to a novel flat thermotube with a stratose microflute micro heat pipe group, comprising a metal flat formed by integral extrusion, more than one array through hole arranged side by side is arranged in the flat thermotube; a plurality of micro-fins made from heat conducting material are arranged at the inner wall of the through hole in sequence; a capillary microflute is formed between adjacent micro-fins; the through hole is filled with working substance to form a micro heat pipe; two ends are enclosed to form the integral flat thermotube. The flat thermotube is completely formed by extrusion; the flat thermotube has both simple structure and high reliability and is capable of remarkably reducing volume and size of a thermotube system to achieve remarkable miniaturization or micromation so as to result in brand new application and popularization of the thermotube technology in the heat exchange field or the cooling field, thereby having high social and economic values. Meanwhile, the flat thermotube of the invention can be applied to other heat exchange fields to replace the existing various heat exchangers.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a flat heat pipe with a micro heat pipe group having micro grooves. Background technique [0002] Compared with other heat exchange technologies, heat pipes have the characteristics of high heat exchange efficiency, small size, low cost, and high reliability. Therefore, they have been widely used and developed in industry and daily life. [0003] Traditional heat pipes generally use circular tubes with a certain diameter, and the two ends are closed after filling the working fluid. Compared with other heat pipes, such as shell-and-tube heat exchangers, plate heat exchangers, etc., this structure not only has high heat exchange efficiency , and small size, long service life, maintenance-free and other advantages. [0004] For the flat heat exchange surface, the use of flat heat pipes has the characteristics of small thermal resistance and high heat exchange efficiency, but ...
