Description
Technical field
The present invention relates to a kind of slim heat pipe structure and manufacturing approach thereof, You Zhike realizes slimming and promotes hot transfer efficiency and the slim heat pipe structure and the manufacturing approach thereof of the yield rate of lifting manufacturing process.
Background technology
Heat pipe, the pyroconductivity on it is apparent are about several times to tens times of metals such as copper, aluminium and therefore suitable excellence is that quilt is applied to various hot countermeasure correlation machines with element as cooling.From shape, heat pipe can be divided into the heat pipe of round tube shape, the heat pipe of flat shape.For the part to be cooled of the e-machine that cools off CPU etc., in part to be cooled and can obtain the viewpoint of broad contact area, should use planar heat pipe to dispel the heat based on easy mounting.Along with miniaturization, the save spaceization of cooling body,, necessity of the utmost point slimming of being strict with this heat pipe is arranged more in the situation of the cooling body that uses heat pipe.
Be provided with the stream that the space is used as working fluid at inside heat pipe, be contained in the working fluid in this space, the phase change through evaporation, condensation etc. and move etc., and carry out the transfer of heat.The action of next detailed explanation heat pipe, this heat pipe possesses the blank part of sealing, the phase change of the working fluid through being contained in this blank part with move the transfer of carrying out heat.
Therefore; Industry adopts the element of heat pipe as heat conduction, and heat pipe is arranged in the radiating fin, utilizes low boiling hydraulic fluid (evaporation ends) heat absorption evaporation at the heat-generating electronic elements place of inside heat pipe filling; Move to radiating fin; (condensation end) is passed to radiating fin with the heat that heat-generating electronic elements produces at the radiating fin place, utilizes radiator fan that the heat that produces is taken away, and accomplishes the heat radiation to electronic component.
The manufacturing approach system of heat pipe sees through and in a hollow tube, inserts metal dust; And the mode that this metal dust sees through sintering formed a capillary structure layer in this hollow tube inwall; This body vacuumized and insert the last tube sealing of working fluid thereafter; Because of the slimming demand of electronic equipment, need heat control is made slim.
Known technology system sees through processes hollow tube flattening flat tabular; Use the demand that meets slimming; Capillary sintered body inserted this hollow tube in, insert working fluid again and vacuumize and the tube sealing operation, though it can process flat with heat pipe thereafter; But if opposite heat tube is when bending moulding, the position that then inner capillary sintered body then can embrittlement decomposes or break away from original setting becomes substandard product.
Other is the person; Also there is industry technical staff that heat control is made when slim; At first be heat pipe to be filled out behind the powder sintering this heat pipe flattened become flat, carry out tube sealing at last after inserting working fluid thereafter, or the body of heat pipe is pressed into is flat-shapedly filling out the powder sintering operation thereafter earlier; But because of the body internal chamber very narrow; Cause and fill out the powder job execution and be difficult for, and because the capillary structure in the heat pipe will have concurrently simultaneously and support and the capillary force conduction is used, then effect is limited in too narrow space.
Person in addition, the steam channel of inside heat pipe will be because of the excessive narrow vapour-liquid circulation that influences, and then this manufacturing process and structure are very inappropriate.
So known technology has disadvantage:
1. the processing of slimming heat pipe is difficult for;
2. capillary structure in the destructible heat pipe;
3. manufacturing cost is higher.
Summary of the invention
The present invention's main purpose is providing a kind of slim heat pipe structure of realizing the heat pipe slimming.
Another purpose of the present invention is providing a kind of slim heat pipe structure manufacturing approach that can be made into the slimming heat pipe.
For reaching above-mentioned purpose, the present invention proposes a kind of slim heat pipe structure, is to comprise: a body, one first supporter;
Said body has at least one accommodation space and one first blind end and one second blind end, and said first and second blind end is communicated with aforementioned accommodation space, has working fluid in this accommodation space; This first supporter is arranged in the aforementioned accommodation space and defines one first chamber and one second chamber jointly with this accommodation space, and this first and second chamber is axially set in this body.
For reaching above-mentioned purpose, the present invention proposes a kind of slim heat pipe structure manufacturing approach, is to comprise the following step:
One body and one first supporter are provided;
This first supporter is inserted in this body;
This body added be pressed into flat;
This body is vacuumized and inserts working fluid;
Seal this body.
See through the present invention's slim heat pipe structure and manufacturing approach thereof, be to make the Heat Pipes slimming, and significantly promote hot transfer efficiency.
