With reference to Fig. 1, Fig. 2 and shown in Figure 3, the utility model provides a kind of radiating fin group and heat pipe assembly positioning structure, and it mainly comprises a plurality of radiating fin group 1,1 ', at least one heat pipe 2 and support and end plate 3, wherein:
Radiating fin group 1,1 ' by a plurality of radiating fins 11,11 ' punching press is stacked to form, at each radiating fin 11,11 ' the position of going up corresponding heat pipe 2 is provided with perforation 12 (figure does not show), 12 ', and at each radiating fin 11,11 ' punching out perforation 12, extended to form ringwall 13 in the time of 12 ', 13 ', ringwall 13,13 ' has perforation of being connected 12, oblique cone portion 131 on the 12 ' peritreme, 131 ' (as shown in Figure 5), and from oblique cone portion 131, the compressed part 132 that 131 ' bore smaller part extends, 132 ', when each radiating fin 11,11 ' when stacking together one by one, back a slice radiating fin 11,11 ' perforation 12,12 ' is nested with at preceding a slice radiating fin 11,11 ' compressed part 132, on 132 '.Heat pipe 2 can be the kenel of water cooling tube or heat pipe (Heat Pipe), and its shape can be the U-shaped pipe, in order to be set on a plurality of groups of radiating fin groups 1, on 1 ', and the compressed part 132 that makes last radiating fin 11 is embedded between the oblique cone portion 131 and heat pipe 2 outer peripheral edges of rear radiating fin 11, compress the radiating fin 11 of the superiors downwards with anchor clamps (figure does not show), to dwindle the spacing of 11 of each radiating fins, and will have being installed on the radiating fin group 1 ' of the superiors of through hole 31 to ending plate 3, and supporting the thickness that ends plate 3 must be greater than radiating fin 11,11 ' thickness supports the fixing strength of ending plate 3 to increase.At last, the bottom with heat pipe 2 is erected on the heat-conducting plate 4 again, to constitute heat spreader structures.
In addition, for satisfying the different demands of the heat that various pyrotoxin produces, and support to end the difference of the fixing strength that plate 3 presses downwards, can be as the structure kenel of present embodiment, adjacent two radiating fin groups 1,1 ' between a pair of spacer 5 is installed, this spacer 5 is provided with the through hole of establishing for heat pipe 2 strings 51, and is equipped with on the radiating fin group 1 ' of the superiors to ending plate 3, to improve closeness of contact.
In the utility model, before heat pipe 2 and each radiating fin 11 wear, can on the outer surface of heat pipe 2, be coated with one deck heat-conducting medium (not shown), this heat-conducting medium is a high density segmentation minor structure, as silicone oil, mineral oil or polypropylene glycol methyl ether (Polyethylene Glycol, PEG) etc., and has a lubricated effect, thereby when being worn, heat pipe 2 and each radiating fin 11 can be more prone to, and because this heat-conducting medium belongs to high density segmentation minor structure again, thereby can fill up the space of 132 of the compressed part of heat pipe 2 and each radiating fin 11 fully, to increase the contact effect.
In the utility model, support to end plate 3 and spacer 5 thereof when string is located on the heat pipe 2, coating sticker through hole 31,51 in earlier is to increase the fixing strength of supporting 2 of plate 3 only and spacer 5 thereof and heat pipes.
Continuation is with reference to Fig. 4, shown in Figure 5, to be set on the heat pipe 2 to ending plate 3, make to ending plate 3 location and support the place, top of ending in radiating fin group 1 ', before being embedded in, the compressed part 132 ' of back a slice radiating fin 11 ' of radiating fin group 1 ' locates (as shown in Figure 5) between the oblique cone portion 131 ' of radiating fin 11 ' and heat pipe 2 surfaces, to dwindle the spacing between each radiating fin 11 ', and then can make the ringwall 13 ' between each radiating fin 11 ' embed and be pressed on the heat pipe 2 successively, and be face with 2 of heat pipes and contact, to improve closeness of contact.
Fig. 6 is the generalized section of the utility model second embodiment.With reference to shown in Figure 6, support and end plate 3 except sentence the top that can be installed in radiating fin group 1 ', support to end plate 3 and also can be installed in the place, below of another radiating fin group 1, make two radiating fin groups 1,1 ' place, upper and lower both sides end plate 3 clampings and be positioned on the heat pipe 2 by supporting.
Fig. 7 is the section action schematic diagram of the utility model the 3rd embodiment.With reference to shown in Figure 7, when the sheathed three groups of radiating fin groups 1,1 ', 1 that are stacked with on heat pipe 2 " time; at first, will be set on the heat pipe to ending plate 3 earlier, again with radiating fin group 1 in the tight fit mode; be set on earlier on the heat pipe 2; secondly, a pair of spacer 5 is attached on the radiating fin group 1, and applies the power that compresses downwards; make the ringwall 13 of 11 of each radiating fins of radiating fin group 1 embed successively and be pressed on the heat pipe 2, to dwindle the spacing of 11 of each radiating fins.
Then, radiating fin group 1 ' is set on the heat pipe 2, radiating fin group 1 ' location is supported only to be located above last radiating fin group 1, moreover, another is attached on the radiating fin group 1 ' spacer 5 ', and apply the power that compresses downwards, make the ringwall 13 ' between each radiating fin 11 ' of radiating fin group 1 ' embed successively and be pressed on the heat pipe 2, to dwindle the spacing between each radiating fin 11 '.
Then, with radiating fin group 1 " be set on the heat pipe 2; make radiating fin group 1 " locate and support the place, top of ending in last radiating fin group 1 ', at last, supporting another only again, plate 3 is set on the heat pipe 2, make to ending plate 3 location and support the place, top of ending, thereby make three radiating fin groups 1,1 ', 1 in last radiating fin group 1 ' " location supports and ends on heat pipe 2, and can force each radiating fin 11,11 ', 11 " ringwall 13,13 ', 13 " with the driving fit more that contacts of 2 of heat pipes.
In the utility model, heat pipe 2 is not limited to the U-shaped pipe, also can be the heat pipe 2 of other different shape, for example, stereo appearance figure with reference to the utility model the 4th embodiment shown in Figure 8, heat pipe 2 ' the elliptical tube that slightly takes the shape of the letter U, relatively, perforation on the radiating fin 11,11 ' 12,12 ' and support also ovalize of the through hole 41 that ends on the plate 4.Perhaps, the stereo appearance figure of the utility model the 5th embodiment as shown in Figure 9, heat pipe 2 " rectangular pipe that slightly takes the shape of the letter U (or being called temperature-uniforming plate), relatively, perforation on the radiating fin 11,11 ' 12,12 ' and support the through hole 41 that ends on the plate 4 and also be rectangle.
In sum as can be known, in the process that a plurality of radiating fin groups 1,1 ', 1 ' are pressed on the heat pipe 2, can end function by supporting, prevent radiating fin group 1,1 ', 1 to the location of ending plate 4 and spacer 5 thereof " transport the distortion that gets loose in the process in assembling, and then reduce the defect rate of product.Simultaneously, utilize to ending the downforce that plate 4 and spacer 5 are applied, can force each radiating fin 11,11 ', 11 " ringwall 13,13 ', 13 " with the driving fit more that contacts of 2 of heat pipes, heat passes effect and is greatly improved naturally, to help the colling end quick heat radiating of heat pipe 2.
Yet, the above only is a preferred embodiment of the present utility model, be not so promptly limit claim of the present utility model, the equivalent structure transformation that every utilization the utility model specification and accompanying drawing content are done, directly or indirectly be used in other relevant technical field, all in like manner be included in the claim of the present utility model.
