With reference to shown in Figure 5, radiator of the present invention also can comprise groups of fins 40.Groups of fins 40 is formed by a plurality of fin 41 mutual stacked combination, is provided with on each fin 41 corresponding to collinear through hole 42 (figure does not show).Through hole 42 wears connection for the radiating end 22 of each heat pipe 20.In addition, closed fan frame 50 at the exterior circumferential cover of heat pipe 20 and groups of fins 40, the bottom of fan frame 50 is concaved with fixed head 51.Fixed head 51 is provided with the hole of the location hole 16 of corresponding heat-conducting block 10, and is fixedly connected for fixation kits such as screw, rivets.
With reference to shown in Figure 6, can install first fan 60 and second fan 61 in the forward and backward both sides of fan frame 50 respectively, and radiator of the present invention is arranged on pyrotoxin 70 (as: central processing unit) top.Pyrotoxin 70 will produce high heat in operation, these heats will be directly from the surface conductive of pyrotoxin 70 on the heat absorbing end 21 and heat-conducting block 10 of each heat pipe 20, and by the gas-liquid phase heat transfer mechanism of each heat pipe 20 inside and the conduction of heat of heat-conducting block 10, with heat is derived fast band from, and by being serially connected in heat transmission, the diffusion of the groups of fins 40 on each heat pipe 20, reach the forced air supply of each fan 61,62, significantly promote the heat dissipation of radiator.
With reference to Fig. 7, Fig. 8 and shown in Figure 9, the invention provides a kind of manufacture method of radiator, its step is as follows:
A) at first, prepare radiator material, an end of heat pipe 20 is passed the perforation 13 of heat-conducting block 10, and the other end of heat pipe 20 is embedded in the non-open slot 12 of heat-conducting block 10.In this step, can be earlier at the heat absorbing end 21 inboard coated with thermally conductive media 30 of heat pipe 20, two radiating ends 22 with heat pipe 20 pass the perforation 13 of heat-conducting block 10 from lower to upper from the bottom of heat-conducting block 10 again, and the heat absorbing end 21 of heat pipe 20 is embedded in the non-open slot 12 of heat-conducting block 10.The top peripheral shape is corresponding cooperates for the heat absorbing end 21 of the peripheral shape of non-open slot 12 and heat pipe 20, so that heat pipe 20 is able to attach mutually contact (as shown in Figure 7) with 10 of heat-conducting blocks.
B) secondly, on the groove 81 that the heat-conducting block 10 after the combination and heat pipe 20 are arranged on mould 80 accordingly.In this step, owing to be provided with depressed area 82 (as shown in Figure 8) in the groove 81 of mould 80 and under the non-open slot 12 corresponding to heat-conducting block 10, so can be earlier in the depressed area 82 of heat absorbing end 21 outsides of heat pipe 20 and mould 80 each coated with thermally conductive medium 30, the flat board 15 of heat-conducting block 10 is crossed on the end face of mould 80, body 11 bottom surfaces of heat-conducting block 10 then are flattened on groove 81 surfaces of mould 80 again.
C) in addition, heat-conducting medium 30 is injected from the perforation 13 of heat-conducting block 10, and fill out the space that the depressed area 82 that is distributed in heat pipe 20, heat-conducting block 10 and mould 80 is surrounded.In this step, heat-conducting medium 30 can be made by materials such as tin creams, can heat-conducting medium 30 be injected from perforation 13 tops of heat-conducting block 10 by modes such as extruding, simultaneously by 13 chamferings 14 that are provided with of boring a hole, in the space that the depressed area 82 that makes heat-conducting medium 30 be easy to filling heat-conductive piece 10, heat pipe 20 and mould 80 is surrounded, heat-conducting medium 30 is covered with on chamfering 14, with replenishing as the heat-conducting medium 30 of heat fused.And moderately adjust the relativeness of heat pipe 20 and heat-conducting block 10, so that each heat pipe 20 is provided with perpendicular to heat-conducting block 10.
D) moreover, mould 80 heating so that heat-conducting medium 30 fusings are filled up aforesaid space and infiltrate, lower the temperature and is cooled off so that heat-conducting block 10 is connected with heat pipe 20.In this step, the heat-conducting block 10, heat pipe 20 and the mould 80 that are marked with heat-conducting medium 30 can be sent into the heating furnace heating, so that heat-conducting medium 30 is able to evenly infiltrate in the hole or slit of filling up 20 of heat-conducting block 10 and heat pipes, and, behind heat-conducting medium 30 expanded by heating, can make its liquid fluid not produce overflow phenomena by the chamfering 14 that perforation 13 is provided with.Cooling method then can place cooling under the normal temperature, again the radiator after this moulding is taken off (as shown in Figure 9) from mould 80.
E) in addition, make it form the plane to the radiator bottom surface processed after the moulding.In this step, because the heat-conducting medium 30 after the moulding protrudes from body 11 bottom surfaces of heat-conducting block 10, so can pass through surface grinding machine, emery cloth, sand paper or abrasive band etc., directly processing grinding is carried out in the bottom surface of radiator, and make the root edge of radiator in the same plane, wherein the heat-conducting medium 30 that is bonded at heat-conducting block 10 bottom surfaces can be removed fully, so that each root edge of heat-conducting block 10 and heat pipe 20 is in the same plane.
In addition, the manufacture method of radiator of the present invention can comprise that also step f) is socketed in groups of fins 40 on the radiating end 22 of heat pipe 20.In this step, be socketed in again on the heat pipe 20 after groups of fins 40 is can be with a plurality of fin 41 stacked mutually, or in regular turn with each fin 41 being socketed on the heat pipe 20 one by one.
Therefore, by above-mentioned steps flow chart, can obtain the manufacture method of radiator of the present invention.
By after the above-mentioned explanation as can be known, the present invention directly is contacted with on pyrotoxin 70 surfaces of electronic installation by heat absorbing end 21 root edges of heat pipe 20, and being tightly connected of 10 of heat pipe 20 and heat-conducting blocks, and is significantly increased the thermal conduction rate and the lifting heat dissipation of radiator.
Yet above-mentioned disclosed accompanying drawing and explanation are embodiments of the invention only, and the present invention is not limited thereto.Will be understood by those skilled in the art that according to feature category of the present invention, other equivalent transformation or the modification done all should be encompassed in the claim scope of the present invention.
