Fig. 2-7, a kind of intelligent terminal heat pipe 1 of the utility model embodiment are please referred to, including is stacked and is welded in one
Upper copper sheet 10 and lower copper sheet 20, the top surface of lower copper sheet 20 has groove 21 along its length, copper powder is equipped in groove 21 and is burnt
Fluid passage 22 made of knot are equipped with steam channel 23 between 21 edge of fluid passage 22 and groove, are equipped in fluid passage 22
Liquid, and groove 21 is vacuum negative pressure condition.
Wherein, the wall thickness of upper copper sheet 10 and lower copper sheet 20 is 0.05mm-0.1mm.
Further, multiple support columns 25 are arranged in groove 21 and its length direction interval.
Further, it is provided with the water injection pipe 30 sealed on lower copper sheet 20, in flat, thickness is about water injection pipe 30
0.3mm.Working fluid is injected in the groove 21 enclosed by this upward copper sheet 10 of water injection pipe 30 with lower copper sheet 20, injection work is complete
Water injection pipe 30 is sealed after.
Specifically, water injection pipe is copper pipe, and the diameter of copper pipe is 1mm, wall thickness 0.1mm.
In the present embodiment, upper copper sheet 10 is in "-" type with lower copper sheet 20, therefore welds the intelligent terminal heat pipe formed and be also in
"-" type.It certainly, can also be as shown in figure 8, upper copper sheet 10 and lower copper sheet 20 be L-shaped.Alternatively, upper copper sheet 10 and lower copper sheet 20 are equal
In S font.
Referring to Fig.1, the production method of intelligent terminal heat pipe 1 provided by the embodiment of the utility model, including following technique step
It is rapid:
S1, preparation can be stacked the upper copper sheet 10 and lower copper sheet 20 of docking, square along its length in the top surface of the lower copper sheet 20
To groove 21 is opened up, fluid passage 22, the fluid passage 22 and institute made of being sintered as copper powder are set in Yu Suoshu groove 21
It states and reserves steam channel 23 between 21 edge of groove, the liquid injection port being connected to the groove 21 is set in lower 20 side of copper sheet
24。
Specifically, as shown in Figure 2 and Figure 3, in this step, the upper copper sheet 10 of preparation is in "-" type structure, and upper copper sheet 10
Bottom surface be plane.By etching with a thickness of the copper sheet of 0.2mm, upper 10 thickness range of copper sheet after molding is upper copper sheet 10
0.05mm-0.1mm.Correspondingly, lower copper sheet 20 is also in "-" type structure, and length, width matches with upper copper sheet 10, ultimately form
Intelligent terminal heat pipe 1 be also be in "-" type structure (as shown in Figure 7).Certainly, in other embodiments, according to practical intelligence
Terminal inner structure is different, and heat pipe shape can also be different, as shown in figure 8, when intelligent terminal heat pipe 1 is L-type, in this step,
Directly prepare the lower copper sheet 20 of L-shaped upper copper sheet 10 and L-type.Alternatively, upper copper sheet 10 and lower copper sheet 20 are S-type etc..
In this step, reference fig. 4 to fig. 6, groove 21 are formed using etching, and are grown in groove 21 along it in etching
Reserve multiple spaced support columns 25 in degree direction.Using multiple support columns 25, keep lower 20 inner plane degree of copper sheet more preferable,
Structure is stronger.Wall thickness is 0.05mm-0.1mm to lower copper sheet 20 after the etching.Likewise, the wall thickness of upper copper sheet 10 is 0.05mm-
0.1mm.Upper copper sheet 10 and lower 20 thickness matching of copper sheet, to ensure to form the stability of heat pipe after welding.
In this step, fluid passage 22 made of copper powder sintering is one, and fluid passage 22 is in "-" type.Liquid is logical
Road 22 is equipped with multiple apertures 221, corresponds with multiple support columns 25.When fluid passage 22 is placed in groove 21, each support column
25 pass through each aperture 221.It is of course also possible to be sintered to form a plurality of fluid passage 22.Moreover, fluid passage 22 and 21 edge of groove
Between the steam channel 23 reserved be in U type, it is of course also possible to reserved one or more "-" type steam channel 23.
In this step, certain region is reserved between 21 peripheral distance of groove and the edge of lower copper sheet 20, this region is
Scaling powder region 26.
Further, in this step, when copper sheet 10 is with lower copper sheet 20 in preparation, in the both sides of the edge of upper copper sheet 10, setting is more
A upper locating plate 11, the both sides of the edge of lower copper sheet 20 are correspondingly arranged multiple lower locating plates 27.
S2, the upper copper sheet 10 is stacked with the lower copper sheet 20 and is docked, water injection pipe 30 is plugged at Yu Suoshu liquid injection port 24,
And the upper copper sheet 10, the lower copper sheet 20 and the water injection pipe 30 are welded as a whole.
In this step, by upper copper sheet 10 and lower copper sheet 20 are stacked dock when, by upper locating plate 11 and lower locating plate 27
Fitting docking, the Dock With Precision Position between upper copper sheet 10 and lower copper sheet 20 provide reliable positioning datum respectively, it is ensured that do not occur
Dislocation.
In this step, water injection pipe 30 is copper pipe, and the diameter of copper pipe is 1mm, wall thickness 0.1mm.
Liquid is injected in S3, Xiang Suoshu water injection pipe 30, and is extracted vacuum by the water injection pipe 30 and sealed.
In this step, before welding in scaling powder region 26 place scaling powder 40, using scaling powder 40 by upper copper sheet 10,
Lower copper sheet 20 and water injection pipe 30 are welded as a whole.Specifically, scaling powder 40 is copper fibre material.In welding, copper fibre material fills upper copper
Gap between plate 10 and lower copper sheet 20, the seamless connection in guarantee between copper sheet 10 and lower copper sheet 20.
Working fluid is injected by water injection pipe 30 after the completion of welding, then extracts vacuum, allows copper sheet 10 and lower copper sheet 20
Between space keep negative pressure state, then water injection pipe 30 is sealed.Specifically, using cutter mould and mash welder by water injection pipe
30 sealings, then sealing part is crushed to 0.3mm thickness.Finally, lower locating plate 27 and lower locating plate 27 are cut, formed final
Intelligent terminal heat pipe 1.The thickness of finished product intelligent terminal heat pipe 1 is by the groove on upper copper sheet 10, lower copper sheet 20 and lower copper sheet 20
21 depth is formed by stacking, and the thickness using finished product intelligent terminal heat pipe 1 made of the above method is about 0.3mm.
In the utility model embodiment, intelligent terminal is made by the way of upper copper sheet 10 and the stacked welding of lower copper sheet 20
Upper copper sheet 10 and the setting of lower copper sheet 20 can be in directly required shape, for spy in this way by the way of separating selection by heat pipe 1
Other shape is not required to carry out bending again after shaping, and such processing is not limited by shapes and sizes, will not generate fold,
Strong applicability；And internal fluid passages 22 are sintered using copper powder, perfect heat-dissipating.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
