The specific embodiment
In order further to understand feature of the present invention and technology contents, consult following about detailed description of the present invention and accompanying drawing, yet accompanying drawing only provide with reference to and be used for illustrating, be not to be used for the present invention is limited.
Consult Fig. 1, the invention provides a kind of loop type heat pipe structure, it roughly comprises evaporimeter 1, fluid-tight container 2 and closing pipe line 3.Wherein:
What evaporimeter 1 was loop type heat pipe is subjected to the thermal site part, and it has by the made evaporation body 10 of heat-conducting, and described heat-conducting can be aluminium or copper material etc.So evaporation body 10 is essentially heat exchange block (heat spreader), and has contact-making surface 100 (as shown in Figure 3) in order to develop mutually with thermal source 5.Thermal source 5 is meant electronic heating component, is generally central processing unit (CPU), but is not limited to this.And in the present embodiment, be provided with first containing hole 101, second containing hole 102 and the 3rd containing hole 103 at least on the evaporation body 10, and between per two described containing holes 101,102,103, be through with access opening 104,105.As shown in this embodiment, be through with access opening 104 between first and second containing hole 101,102, then be through with access opening 105 between second and third containing hole 102,103.
Consult shown in Figure 2 in the lump, fluid-tight container 2 can be heat pipe (heat pipe), after it penetrates in second containing hole 102 that evaporates body 1, further use tin solder or heat-conducting glue etc. to have the scolder or the sticker of heat-conducting effect again, set firmly the joint operation with the fluid-tight container 2 and second containing hole 102 are welded, gummed etc., fluid-tight container 2 is installed in second containing hole 102.Fluid-tight container 2 inwalls are pasted with capillary structure 20, and pile up certain thickness and form wet seal area 200 with capillary structure 20 in one end place.And described " end " is that bottom 21 with general heat pipe is for good, because the other end is for injecting sealing end 22 with operations such as vacuumizing in order to carry out working fluid, so capillary structure 20 is unfavorable for being blocked in sealing end 22 places.In addition, the capillary structure 20 on fluid-tight container 2 inwalls can by powder sintered form or curl with wire netting 201 (as shown in Figure 4) after insert, wet seal area 200 is then all with powder sintered formation.
Closing pipe line 3 can be formed by body 30 curved establishing, and is perhaps connected continuously to be provided with by the body more than two or two 30,31 to form (as shown in Figure 5), and is pasted with capillary structure at body 30,31 inwalls.In the present embodiment, closing pipe line 3 bends to the loop shape by body 30.And body 30 has two blind ends 300,301, two blind ends 300,301 penetrate respectively in first and third containing hole 101,103 of evaporation body 10, and the scolder or the sticker that further use tin solder or heat-conducting glue etc. to have heat-conducting effect, set firmly the joint operation with two blind ends 300,301 of body 30 and evaporation body 10 are welded, gummed etc.Then, wear described access opening 104,105 from evaporation body 10 outsides again.Consult Fig. 2 and shown in Figure 3 earlier, access opening 104,105 is all blind hole to evaporation body 10, and it is only in order to connect between fluid-tight container 2 and two blind ends 300,301.And then after closing pipe line 3, fluid-tight container 2 were bonded into one with evaporation body 10, closing pipe line 3 can constitute closed circuit by access opening 104,105, promptly as shown in Figure 1.Simultaneously, access opening 104,105 is provided with sealing 106 in evaporation body 10 outsides, sealing 106 can be a cock body, and (plug forms welding structure (as shown in Figure 4) as shown in Figure 3) or for filling up by the welding fusion, effectively access opening 104,105 is sealed in evaporation body 10 inside.
And after closing pipe line 3, fluid-tight container 2 form closed circuit with access opening 104,105, in first and third containing hole 101,103 of evaporation body 10, have one at least for running through the through hole that evaporates body 10.The present invention for embodiment in, be to be all the through hole kenel for example with first and third containing hole 101,103.So, be convenient to that at least one described blind end 301 end can protrude out outside the evaporimeter 1 from the containing hole 103 that is the through hole kenel in the closing pipe line 3, and protrude out the sealing end that blind end 301 outside the evaporimeter 1 is body 30.Can be from here before not sealing clean, vacuumize or operation such as degasification, form enclosuring structure 302 through production process such as the draw, pressing and welding with blind end 301 is terminal again after finishing to operation closing pipe line 3 and access opening 104,105.In addition, have the condensing zone 303 of a place or many places on the lower tube body 30, and can further descend to wear a plurality of radiating fins 4 on the condensing zone 303.
And the present invention piles up with capillary structure 20 in fluid-tight container 2 one end places and is formed with wet seal area 200, wet seal area 200 can allow the working fluid that is in a liquid state after the condensation be full of wherein and form fluid-tight, to form the evaporating area of maximum area, make that thermal resistance is little, heat output is greater and faster naturally, and then possess good heat transfer characteristic.
Therefore, form, can obtain loop type heat pipe structure of the present invention by above-mentioned structure.
In addition, as shown in Figure 5, in the present embodiment, closing pipe line 3 is connected continuously to be provided with by the body more than two or two 30,31 and forms, and 30,31 of each bodys are connected in series mutually with a contiguous block 6.Contiguous block 6 mainly is provided with for each body 30,31 or fluid-tight container 2 bottoms and penetrates two affixed connecting holes 60 and the access opening 61 that connects two connecting holes 60.The place is provided with sealing 62 outside access opening 61 passes contiguous block 6 simultaneously, its structure is similar to evaporimeter 1, but difference is in and need be defined as by heat-conducting made in contiguous block 5, be to connect each body 30,31 and fluid-tight container 2 and it is communicated with each other because of it mainly acts on, rather than in order to contact thermal source 5.
In sum, the present invention can reach the application target of expection really, and solves the disappearance of known technology.Yet above-mentioned accompanying drawing and explanation are embodiment of the present utility model only, and the utility model is not limited thereto.Will be understood by those skilled in the art that according to feature category of the present utility model, other equivalent transformation or the modification done all should be encompassed in the claim scope of the present utility model.
