Embodiment

Below cooperate graphic detailed description embodiments of the present invention.At first see also Fig. 1, the heat abstractor 100 of one embodiment of the invention is mainly formed by the metallic plate processing and fabricating of a rectangle, this metal can be aluminium or copper, the heat pipe 30 that wherein is formed with a plurality of hollows and is arranged in parallel in the inside of metallic plate, then be rib 11 spaces with strip between the aforementioned heat pipe 30, working fluid then can be inserted in order to transferring heat energy in these external heat pipe 30 inside.

What need special instruction is that when the heat abstractor material was aluminium, working fluid was acetone.When the heat abstractor material was copper, working fluid was water, so can reach optimum efficiency, but those skilled in the art should understand the good device materials of other kinds arranging effect and working fluid, do not repeat them here.

See also again Fig. 1～Fig. 3, one end of aforementioned heat abstractor 100 can and form at least one first bend 20 and at least one the second bend 21 (such as Fig. 2, shown in Figure 3) along line of cut 12 cuttings after the different directions bending, wherein on the line of cut 12 configurable ribs 11 between heat pipe 30, cause heat pipe 30 to break in the time of can avoiding cutting thus and cause working fluid to leak.Will be appreciated that, aforementioned heat pipe 30 is arranged parallel to each other in configuration, and can comprise one or more heat pipe 30 between each line of cut 12.

Can be found out by Fig. 2, Fig. 3, the heat abstractor 100 of the present embodiment is formed with a body 10 and a plurality of first,

second bend

20,21 that extends from body 10 after cutting and bending process, wherein aforementioned heat pipe 30 extends to first,

second bend

20,21 from body 10 inside, and the structure that aforementioned body 10 and first,

second bend

20,21 are one of the forming, thereby can be effectively with the end of thermal energy transfer to heat abstractor 100.

As shown in Figure 2, aforementioned body 10 has a center line C, and body 10 is formed with the turning point 13 of an arcuation, and wherein the first bend 20 and the second bend 21 lay respectively at the opposition side of center line C.In the present embodiment, a tangent line direction and the center line C of aforementioned the first bend 20 are formed with the

first angle theta

1, and 1＜180 ° of 0 °＜θ; In addition, a tangent line direction and the center line C of the second bend 21 are formed with the second angle theta 2, and 2＜180 ° of 0 °＜θ.

Thus, first,

second bend

20,21 can form dendritic structures at heat abstractor 100 ends, but and then heat radiation usefulness.For example, one side of aforementioned body 10 can be in contact with one another with thermal source 50, can be with thermal energy transfer to first,

second bend

20,21 after the working fluid in the heat pipe 30 is heated vaporization, then then can get back to thermal source 50 places when working fluid after first,

second bend

20,21 cooling liquids and continue to absorb heat energy, so iterative cycles is to reach the effect that continues heat radiation.

Then see also Fig. 4, the heat abstractor of another embodiment of the present invention mainly is all to be provided with first,

second bend

20,21 at the first end 101 of body 10 and the second end 102, thereby can form at body 10 two ends dendritic structure, with enhance heat usefulness further.In the middle of the present embodiment, the more last embodiment of area of dissipation that the first bend 20 and the second bend 21 can form is many, therefore better radiating effect can be arranged.

Then see also Fig. 5 and Fig. 6, as shown in Figure 5, the heat abstractor of another embodiment of the present invention mainly is that line of cut 12 is arranged between the first end 101 and the second end 102 of body 10, can be after cutting be finished, towards upper and lower at least one first bend 20 and/or at least one the second bend 21 of bending out.Wherein on the line of cut 12 configurable ribs 11 between heat pipe 30, cause heat pipe 30 to break in the time of can avoiding cutting thus and cause working fluid to leak.Will be appreciated that, aforementioned heat pipe 30 is to be arranged parallel to each other in configuration, and can comprise one or more heat pipe 30 between each line of cut 12.

Although by previous embodiment the present invention is made above explanation, so it is not to limit the present invention.The technical staff in the technical field of the invention, without departing from the spirit and scope of the present invention, when doing a little change and retouching.Therefore protection scope of the present invention is as the criterion when looking the scope that the claims of enclosing define.
