Description
Technical field
The utility model relates to a kind of combined structure for heat radiation apparatus, particularly relates to a kind of radiator punching press a plurality of radiating fins of combination and fixed strip on cooling base.
Background technology
Traditional electronics and electric product radiator are to utilize aluminium as the substrate material of base plate, and make the base plate of radiator in the mode that extrudes, forges or cut, and the mode of radiating fin with welding are fixed on base plate at last again.The heat that the welding material that uses due to welding can increase between base plate and radiating fin passes impedance, and affects the integral heat sink usefulness of radiator, adds lead (Pb) composition that welding material has contaminated environment, and use gradually is under an embargo.In addition, because the arithmetic speed of chip constantly promotes, when estimating the arithmetic speed arrival 3.0GHz of chip, certainly will need the better base material of heat dispersion and more effective mode to make radiator, wherein the radiator with fine copper or copper alloy will become following main product.
Prior art also can utilize the mode of die forging to make radiator 100, as depicted in figs. 1 and 2, base plate 110 and the radiating fin 120 of radiator 100 are not one-body molded, therefore utilize the mode of die forging the invayination 122 of radiating fin 120 to be embedded in the groove 112 of base plate 110.as shown in the figure, at first the invayination 122 with each radiating fin 120 is disposed at respectively on the groove 112 of base plate 110, be slightly less than the width of groove 112 because of invayination 122 width of radiating fin 120, therefore failing directly to inlay, the invayination 122 of radiating fin 120 is fixed among groove 112, and must utilize the squeezing knife tool (not shown) to be placed between adjacent two radiating fins 120, form piston ring land 114 with punching press base plate 110 surface extruding down, and make piston ring land 114 pressurizeds produce plastic deformation, and by cutter both sides outwards pushing to groove 112, therefore contiguous groove 112 is pushed, make the invayination 122 of radiating fin 120 be embedded in groove 112.
Have now and utilize the die forging mode to make radiator 100, the heat-conductive characteristic between radiating fin 120 and base plate 110 is significantly promoted.Yet it should be noted that, when cutter pushes piston ring land 114 with larger external force, and the amount of plastic deformation that makes piston ring land 114 is when increasing, extruded piston ring land 114 is because can't lead off fully to the both sides of groove 112, can push to the bottom of ditch mortise 112 on the contrary, the effect that causes radiating fin 120 upwards to be pushed, and change its degree of depth, and can stay the space between the bottom of groove 112 and radiating fin 120, and then affect the heat-conducting effect of radiating fin 120 and base plate 110.In addition, cutter increases because impacting power, and the knife edge of cutter is relatively impaired more serious, shortens on the contrary cutting-tool's used life.
The utility model content
The purpose of this utility model is to provide a kind of combined structure for heat radiation apparatus, it utilizes each fixed strip to be pressed in the relative positioning groove of cooling base and between radiating fin, and each fixed strip becomes the crimp body towards lower compression, make the crimp body form lateral spread section, be fixed between location notch and relative radiating fin one side thereof with crowded, reach firm urgent positioning function, and facilitate making, processing and volume production.
For achieving the above object, heat abstractor of the present utility model includes: a cooling base, and its metal pedestal surface is interval with a plurality of location notchs; A plurality of radiating fins, its metal lamellar body one end is inserted in respectively in the location notch of relative cooling base down, and the thickness of each radiating fin is less than the width of relative positioning groove; A plurality of fixed strips, keep flat in the relative positioning groove that is pressed on cooling base, and it is positioned at a side of relative radiating fin, each fixed strip is made as the crimp body towards lower compression, make the crimp body have lateral spread section, be fixed in location notch and relatively between radiating fin one side with crowded.
According to preferred embodiment of the present utility model, this radiating fin can be different metal materials each other from fixed strip.Again, this radiating fin and fixed strip each other section can be different thickness.
According to preferred embodiment of the present utility model, the section of this fixed strip can be made as rectangle, circle, polygonal or ellipse.
By taking above technical scheme, the concrete following beneficial effect of the utility model: the utility model utilizes each fixed strip to be pressed between the interior and radiating fin of the relative positioning groove of cooling base, and each fixed strip becomes the crimp body towards lower compression, make the crimp body form lateral spread section, be fixed between location notch and relative radiating fin one side thereof with crowded, reach firm urgent positioning function, and facilitate making, processing and volume production.
