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
The present invention relates to the heat transfer technology field, particularly relate to a kind of plate shaped heat pipe with low-grade fever nest of tubes of microflute.
Background technology
Heat pipe has the heat exchange efficiency height for other heat transfer technology, volume is little, and cost is low, and therefore high reliability features, in industry and daily life, has all obtained large-scale application and development.
Traditional heat pipe generally is to adopt the pipe with certain diameter, closed at both ends after the can working medium, and this structure is compared other heat pipe, as shell-and-tube heat exchanger, plate type heat exchanger etc., not only heat exchange efficiency height, and volume is little, long service life, advantage such as non-maintaining.
For dull and stereotyped heat-transfer surface, adopt flat-plate heat pipe to have the characteristic that thermal resistance is little, heat exchange efficiency is high, but the optimization of structure, bearing capacity, processing technology and heat exchange property all also is in the development phase.Based on capillary slot has obtained good utilization in the circle heat pipe, and the based on capillary slot structure is used for flat-plate heat pipe, when can improve heat pipe heat exchanging efficient, has improved heat pipe structure intensity.
Summary of the invention
The object of the present invention is to provide a kind of novel flat-plate heat pipe with low-grade fever nest of tubes of stratose microflute.
Technical scheme of the present invention is as follows:
A kind of novel flat-plate heat pipe with stratose microflute low-grade fever nest of tubes, it is characterized in that: comprise one by the monolithic extruded metal matter flat board that forms, include the more than one array through hole that is arranged side by side in the described flat-plate heat pipe, be disposed with little fin that some Heat Conduction Materials are made on the described through-hole wall, form the based on capillary slot of stratose between adjacent little fin, be filled with working medium in the described through hole and form micro heat pipe, thereby sealed at both endsly form whole flat-plate heat pipe.
Comprise the micro heat pipe that is arranged side by side more than 2 in the described flat-plate heat pipe, described each micro heat pipe inwall is disposed with little fin, forms based on capillary slot between adjacent little fin.
The channel cross-section of described micro heat pipe is shaped as rectangle or triangle.
In the passage of described micro heat pipe, in each side inwall, a side is provided with little fin.
In the passage of described micro heat pipe, in each side inwall, have at least both sides to be provided with little fin.
Described little fin is for forming with described slab construction one extruding.
Technique effect of the present invention:
The present invention is by utilizing the monolithic extruded slab construction that forms, dull and stereotyped inside is provided with one or more through holes, through-hole wall is provided with little fin, constitute based on capillary slot between adjacent little fin, can working medium in the through hole, dull and stereotyped sealed at both ends, thereby constitute holistic flat-plate heat pipe, owing to be provided with a large amount of little fins in the through hole, on the one hand, can form a large amount of based on capillary slot, on the other hand, these can improve the heat transfer efficiency of flat-plate heat pipe through little fin that extruding forms, and make the traditional relatively heat pipe of flat-plate heat pipe of the present invention have higher heat exchange efficiency and littler volume.
Flat-plate heat pipe of the present invention utilizes dull and stereotyped interior micro heat pipe, because the significantly increase of heat pipe specific area can realize significantly reducing of volume under identical radiating efficiency, can save material consumption.For dull and stereotyped heat-transfer surface, adopting flat-plate heat pipe to have the characteristic that thermal resistance is little, heat exchange efficiency is high simultaneously, is that traditional circular heat pipe is incomparable.But also can be in a lot of fields, in order to substitute existing cooling device, as in field of electronics, because the restriction of structure space, the cooling of electronic devices and components can only rely on fan to finish usually, but use flat-plate heat pipe of the present invention, just the significant miniaturization of flat-plate heat pipe, microminiaturization can be used for electronic devices and components are carried out cooling heat dissipation.
