The specific embodiment

Relevant technology contents of the present invention and detailed description, existing conjunction with figs. is carried out following explanation.

Fig. 1 is radiating fin of the present invention and heat pipe assembling schematic flow sheet.As shown in the figure, the once-forming assemble method of radiating fin of the present invention and heat pipe comprises the following steps: at first, in step 100, prepares sheet metal.

Step 102 is a plurality of radiating fins 1 with the sheet metal drawing.The front 11 of radiating fin 1 is formed with the ringwall 12 of a plurality of protrusions and the snapping portion 13 of accepting at a lateral edges.Offer a plurality of adjacent triangles or the opening 121 of U-shaped on the ringwall 12, opening 121 makes ringwall 12 have the elasticity of coating.Has the perforation 122 that runs through radiating fin 1 in the ringwall 12.Snapping portion 13 is convex shape, and is undertaken on the lateral edges of fin 1.Snapping portion 13 has the head 132 of protrusion, and is reverse setting with ringwall 12.Snapping portion 13 is provided with rectangular through hole 131, so as with snapping portion 13 windings (as shown in Figure 2) of another radiating fin (not shown).

Step 104, a plurality of radiating fins 1 are changed become to put in order string, the head 132 of the snapping portion 13 of radiating fin 1 is tightly fitted among the through hole 131a of the 13a of snapping portion of another radiating fin 1a, make the top of radiating fin 1a place the back side 14 of radiating fin 1, make and form gap 20 (as Fig. 3 A, 3B and shown in Figure 4) between radiating fin 1 and the 1a.

Step 106 is placed on the radiating fin group 10 of bunchiness on the platform 2 of machining machine and tool (as shown in Figure 5).

Step 108 utilizes oil hydraulic cylinder or pneumatic cylinder actuating device 3 the support fin 41 of supporting tool 4 to be pushed the space 20 between the radiating fin group 10 (as shown in Figure 6) from side direction.

Step 110 is sandwiched in a plurality of heat pipes 5 on the clamping device 61 of press-down type mechanism 6 (as shown in Figure 5).

Step 112 when 6 work of press-down type mechanism, penetrates heat pipe 5 in the perforation 122 of each radiating fin 1.Because opening 121 makes ringwall 12 have the elasticity of coating, therefore during by ringwall 12, the inwall of ringwall 12 can be strutted slightly at heat pipe 5, the inwall of ringwall 12 can be coated on after strutting on the surface of heat pipe 5 (as shown in Figure 7) tightly.

Step 114, after heat pipe 5 penetrated each radiating fin 1, the clamping device 61 of press-down type mechanism 6 was decontroled heat pipe 5.

Step 116, the support fin 41 of supporting tool 4 and the clamping device 61 of press-down type mechanism 6 leave radiating fin group 10 and heat pipe 5 simultaneously, promptly finish the winding (as shown in Figure 8) of radiating fin group 10 and a plurality of heat pipes 5.

Fig. 5 is the schematic diagram of radiating fin group of the present invention and a plurality of heat pipe windings.As shown in the figure, the length of the support fin 41 of the supporting tool 4 that discloses in this figure shortens from lower to upper gradually, mainly be because penetrate in the process of radiating fin group 10 at heat pipe 5, the speed that heat pipe 5 penetrates can be more and more slow, so the friction that inwall produced of the perforation 122 of the radiating fin of heat pipe 5 outer surfaces and radiating fin group 10 belows is bigger.For fear of the distortion of ringwall 12 peripheries, the length that supports fin 41 must heal down longer when design.

Because when

heat pipe

5 and 10 windings of radiating fin group, the support fin 41 with supporting tool 4 pushes in each gap 20 of radiating fin group 10 earlier, can prevent that therefore the ringwall of radiating fin 1 is out of shape or heat pipe 5 distortion because of heat pipe 5 extruding.Therefore the outer surface of heat pipe 5 can engage fully with the internal face of ringwall 12 after penetrating, and heat transmission can not hindered, and the heat energy that makes heat pipe 5 be absorbed can be passed on the radiating fin 1 effectively.
