Description

Heat sink

Technical field

The utility model relates to a kind of heat sink, particularly about a kind of the heat pipe and the supporting construction of flattening is combined closely, and forms the heat sink of good heat conduction structure.

Background technology

Heat sink generally is to constitute airtight hollow housing by copper sheet; its hollow space is pumped into vacuum and is inserted working fluid; inner walls is then with capillary structure; so in vacuum; be difficult to control last sintering quality on the technology; it is evenly smooth for the heat sink surface is reached; supporting construction is inserted by regular meeting in hollow housing; traditional supporting construction is utilized copper mesh; and on copper mesh, form a plurality of wavy supporting surfaces; with the upper and lower wall of support hollow housing, also have in hollow housing, to form a plurality of support columns.

But, be supporting construction with the copper mesh, need to form a plurality of wavy supporting surfaces on the copper mesh, technology is comparatively complicated; If adopting support column is supporting construction, then need cooperate and upper and lower two blocks of heat sinks, by the weld job combination, also inconvenient.

In view of this, this creation artificially improves and solves above-mentioned disappearance, is that the spy concentrates on studies and cooperates the utilization of scientific principle, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned disappearance finally.

Summary of the invention

Main purpose of the present utility model is to provide a kind of heat pipe that utilizes to flatten the inner heat sink of filling in supporting construction and forming.

Another purpose of the present utility model, be to provide a kind of by reticulate body in conjunction with supporting construction that cylinder constituted.

A purpose more of the present utility model is to provide the capillary structure on the cylinder of a kind of inwall that is formed at heat sink and supporting construction, to reach good hot conduction.

In order to achieve the above object, the utility model provides a kind of heat sink, and it comprises:

One housing, its inside are to be formed with an accommodation space, and the wall that surrounds the inwall of described accommodation space is provided with capillary structure; And

One supporting construction is arranged in the described accommodation space, and it comprises a reticulate body and a plurality of cylinder, and a plurality of holes of described reticulate body tool and confession group are put the combined hole of described a plurality of cylinders, and the upper and lower end face of described a plurality of cylinders then supports described inwall respectively.

In the preferred implementation, described housing is a flat.

In the preferred implementation, described capillary structure is the capillary structure of copper powder.

In the preferred implementation, described reticulate body is a copper mesh.

In the preferred implementation, described reticulate body extends outstanding a plurality of fixtures from a plurality of ends of described combined hole, reaches group and puts described a plurality of cylinder.

In the preferred implementation, described a plurality of fixtures are to form angle with the plane of described reticulate body.

In the preferred implementation, described a plurality of fixtures are button hook, in order to seize described cylinder on both sides by the arms.

In the preferred implementation, be provided with capillary structure around the described cylinder.

In sum, the utility model compared with prior art has better hot conduction.

The specific embodiment

In order to make your juror can further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

Please refer to Fig. 1, this case is a kind of heat sink 1, and it comprises a housing 11 and a supporting construction 12, wherein:

Described housing 11, its inside are to be formed with an accommodation space 112, and the wall that surrounds the inwall 111 of accommodation space 112 is provided with the capillary structure 111a of copper powder.

Described supporting construction 12, it is to comprise reticulate body 121 and a plurality of cylinder 122, described reticulate body 121 has a plurality of holes 1211, and a plurality of combined holes 1212, described a plurality of combined hole 1212 is slightly larger than hole 1211, wherein said reticulate body 121 extends outstanding several fixtures 1213 from four ends of described combined hole 1212, it shown in the figure button hook form, in order to seize described cylinder 122 on both sides by the arms, but not as restriction, described fixture 1213 is described to be formed with angle (as Fig. 4) with plane reticulate body 121, described a plurality of cylinder 122 is to insert described a plurality of combined hole 1212 respectively, make described a plurality of cylinder 122 respectively in conjunction with being fixed on the described reticulate body 121 by described fixture 1213, and described a plurality of cylinder 122 on, the lower surface is held in described inwall 111 respectively.

Thus, treat that described heat sink 1 is affixed on the heater element (figure slightly), the inwall 11 of bottom can conduct to each cylinder 122 rapidly with used heat, then conducts to the inwall 111 at top, reaches better heat radiating effect, and this is simple in structure, and manufacturing process is more or less freely.

Above-mentioned cylinder 122 can be provided with capillary structure (figure slightly) around it.

As Fig. 5, described housing 11 can be the oval body of pressing, can directly insert supporting construction 12 in the accommodation space 112 of oval body, again to operations such as oval body flatten, vacuumizes, pours water and seals, as shown in Figure 6, form flat at last, utilize heat pipe to flatten innerly to fill in supporting construction and form the purpose of heat sink to reach.

More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
