Embodiment
Please refer to Fig. 1, be the three-dimensional exploded view of heat abstractor of the present invention.The invention provides a kind of heat abstractor 100, it comprises a plurality of fin that are adjacent to connect 10, a heat pipe 20 and a cover plate 30.This figure only part presents present embodiment, and the present invention mainly is to provide does not need scolding tin cover plate 30 is fixed in heat abstractor and the assemble method thereof of fin 10.Below cooperate the thin section of accompanying drawing that this heat abstractor 100 and assemble method thereof is described.
Each this fin 10 have plural fixedly tab 12 its end face, and a supporting part 15 between these a plurality of fixedly tabs 12, define an accommodation space 150 between this supporting part 15 and this a plurality of fixedly tabs 12.Each fin 10 has two fixedly tabs 12 in the present embodiment, yet its quantity is not as limit.Wherein this supporting part 15 of this fin 10 by its apical margin partially towards a lateral buckling.Wherein each this fin 10 further comprises the first brace 11 and one second brace 13, this first brace 11 be positioned at the outside of these a plurality of fixedly tabs 12 and by the apical margin of this fin 10 towards a lateral buckling, this second brace 13 by the root edge of this fin 10 towards a lateral buckling.
This heat pipe 20 has some and is placed in this accommodation space 150.Heat pipe 20 of the present invention can be a flat plate heat tube, utilizes to be closed in its inner hydraulic fluid and capillary structure, with transferring heat promptly.
This cover plate 30 forms a plurality of perforation 32 corresponding to these a plurality of fixedly tabs 12, and wherein these a plurality of fixedly tabs 12 pass these a plurality of perforation 32 and are fixed in this cover plate 30.Wherein the top of these a plurality of fixedly tabs 12 is towards a lateral buckling and be pressed against the end face of this cover plate 30.This cover plate 30 can be metal plate or plastic cement plate body, and this cover plate 30 normally places on the circuit board of electronic installation, and this kind situation is preferably that the thermal insulation board system becomes.Yet not as limit.
Please cooperate Fig. 2, be the assembling schematic diagram of heat abstractor of the present invention.The assemble method of heat abstractor of the present invention comprises following step:
At first, provide complex cooling fin 10, form a pair of fixedly tab 12 at the end face of each this fin 10;
Then, between these a plurality of fixedly tabs 12, form supporting part 15, and form an accommodation space 150 between this supporting part 15 and these a plurality of fixedly tabs 12;
Then, provide heat pipe 20, the some of this heat pipe 20 is placed in this accommodation space 150;
Afterwards, provide a cover plate 30, form a plurality of perforation 32 corresponding to these a plurality of fixedly tabs 12 in this cover plate 30;
Should pass these a plurality of perforation 32 and be fixed in this cover plate 30 by a plurality of fixedly tabs 12.
Fix the step of this cover plate 30 in the present embodiment, comprise that the top that bends these a plurality of fixedly tabs 12 is to be connected to the end face of this cover plate 30.For these a plurality of fixedly tabs 12 of bending, the present invention further provides a tool 9 to bend the top of these a plurality of fixedly tabs 12.This tool 9 can slightly be tabular, and its bottom forms a plurality of pieces 92 that compress with these a plurality of fixedly tabs 12 of backfin.
For making these a plurality of fixedly tabs 12 smoothly towards the same side bending, can be first with the top 12a of this a plurality of fixedly tabs 12, that is protrude from the part of these cover plate 30 end faces, bend obliquely towards the same side first.An end that for example utilizes this tool 9 pushes against gently along the end face of this cover plate 30, makes the top 12a of these a plurality of fixedly tabs 12 become skewed with respect to the position at the root 12b of these a plurality of perforation 32.
Then the piece 92 that compresses of this tool 9 is aimed at the top 12a that these a plurality of fixedly tabs 12 tilt, move down this tool 9, should flatten to push against in this cover plate 30 by a plurality of top 12a, namely finish fixing step.
The above-mentioned tool 9 of the present invention only is a kind of giving an example, and is not restricted to its structure.Please refer to Fig. 3, for example the piece 92a that compresses of tool 9a also can be indentation and have an inclined-plane 921.Cover plate 30 is placed after these a plurality of fin 10, utilize the top 12a that this inclined-plane that compresses piece 92a 921 directly first will these a plurality of fixedly tabs 12 to push into skewed, yet the end face along cover plate 30 moves horizontally tool 9 again, can should flatten to push against in this cover plate 30 by a plurality of top 12a.
After heat abstractor 100 assemblings of the present invention are finished, such as Fig. 4 and shown in Figure 5, do not need scolding tin fully, but utilize fin 10 structures own to fix this cover plate 30, meet the trend of now environmental protection.Cover plate 30 compresses this heat pipe 20 and is connected to this a plurality of fin 10.
See also Fig. 6, be the Application Example of heat abstractor of the present invention, wherein this cover plate 30 further extends to form an extension 34 towards a side, and this extension 34 is fixed a radiator fan 50 contiguous these a plurality of fin 10.This radiator fan 50 brushes these a plurality of fin 10 to accelerate rate of heat dispation.
See also Fig. 7, be the end view of the second embodiment of heat abstractor of the present invention.Comprise further in the present embodiment that at least one shell fragment 36a is arranged at the bottom surface of this cover plate 30 flexibly to be connected to the end face of this heat pipe 20.Present embodiment is that a pair of shell fragment 36a is set, and the end of shell fragment 36a is fixed in this cover plate 30.The purpose of this embodiment is that this heat pipe 20 is pushed against really in these a plurality of fin 10.
See also Fig. 8, be the end view of the 3rd embodiment of heat abstractor of the present invention.Comprise further in the present embodiment that at least one heat insulating mattress 38 is arranged between this cover plate 30 and this heat pipe 20.Heat insulating mattress 38 is preferably to have flexiblely, and its purpose not only can make this heat pipe 20 really push against in these a plurality of fin 10, also can completely cut off heat, in order to avoid be passed to electronic installation towards cover plate 30.
The main advantage of heat abstractor of the present invention and assemble method thereof do not need to be scolding tin with fixing heat pipe in fin; do not need the high temperature through Overwelding and rewelding furnace; can avoid heat pipe 20 through high temperature and impaired, not only can save cost, meet especially the trend of now environmental protection.
Only the above only be better possible embodiments of the present invention, and is non-so namely limit to claim of the present invention, so the equivalence techniques variation of such as using specification of the present invention and accompanying drawing content to do all in like manner all is contained in the scope of the present invention, closes and gives Chen Ming.
