The present invention relates to a heat radiator comprising a base and a plurality of heat radiating fins. The base and the heat radiating fins are all made of metal with favorable heat-conducting performance; in addition, the heat radiating fins are fixed to the base by a punching way. The manufacturing method of the heat radiator comprises the following steps: (1) a base and a plurality of heat radiating fins are provided, and the heat radiating fins are provided with combination parts and heat radiation parts; (2) the combination parts of the heat radiating fins and the base are integrated by a punching way so that the heat radiating fins are fixed to the base; (3) projecting parts formed by punching are removed on the bottom surface of the base so that the bottom surface of the base is flat.
Description
The present invention relates to a kind of Radiator and its preparation method, be meant the Radiator and its preparation method that a kind of radiating effect is good, structure is firm especially.
Along with developing rapidly of information industry, the arithmetic speed of the chip (as central processing unit and display card chip) that electronic installation is inner set is more and more faster, and the ability of its deal with data is also more and more stronger.Yet, the speeding of companion chip arithmetic speed, the heat that it produced also increases considerably.For these heats can promptly be discharged, chip can be moved under normal working temperature, with the quality that guarantees that data are handled, stored and transmit, on the surface of this chip, be equipped with a radiator usually.Existing radiator sees also United States Patent (USP) the 5th, 038, No. 858, the radiator that it disclosed comprises a pedestal and several radiating fins, the upper surface of pedestal offers the slot of several parallel deployings, and this radiating fin is installed in the slot, and with the mutual clamping of slot.This clamping makes between the slot of radiating fin and pedestal and has gap improperly, thereby has influenced the heat transmission between radiating fin and pedestal, causes the radiating effect of radiator not good.
For fear of the problems referred to above, industry has and adopts as United States Patent (USP) the 5th, 625, the radiator that is disclosed for No. 229.This radiator comprises pedestal and radiating fin, and wherein this radiating fin is to be fixed on the pedestal by gluing mode, thereby combination between the two is comparatively tight, is unlikely to produce the gap.Though this kind radiator has solved foregoing problems, exist another drawback, promptly owing to be to combine between radiating fin and pedestal with adhesive means, its in conjunction with and built on the sand, radiating fin have from pedestal come off may.In addition, combined with viscose glue between this radiating fin and pedestal, this viscose glue belongs to the not good material of heat transfer effect eventually, therefore still has to a certain degree influence for the integral heat sink effect of radiator.
The object of the present invention is to provide the Radiator and its preparation method that a kind of radiating effect is good and structure is firm.
The technical scheme of Radiator and its preparation method of the present invention is: this radiator comprises a pedestal and several radiating fins, and this pedestal and radiating fin are made by the heat conductivility good metal, and this radiating fin is to be fixed on the pedestal with impact style.The manufacture method of this radiator is: (1) provides a pedestal and several radiating fins, and this radiating fin has joint portion and radiating part; (2) be combined as a whole by the joint portion and the pedestal of impact style, radiating fin is fixed on the pedestal radiating fin; (3) remove the protuberance that forms because of punching press on the base bottom surface, make base bottom surface smooth.
Because it is above technical characterictic of the present invention, feasible respond well and structure is firm by the prepared radiator heat-dissipation of the present invention.
The invention will be further described below in conjunction with accompanying drawing and embodiment.

Fig. 7 is the three-dimensional view of radiator the 5th embodiment of the present invention.
Fig. 8 is the schematic flow sheet of the manufacture method of radiator of the present invention.
See also Figure 1 and Figure 2, be the first embodiment of the present invention.This radiator comprises a pedestal 10 and several radiating fins 30.Pedestal 10 all is made by heat conductivility good metal (as aluminium alloy) with radiating fin 30, wherein pedestal 10 slightly is tabular, its bottom surface 12 is to contact with thermal source (as central processing unit, display card chip etc.), with respect to the end face 14 of bottom surface 12 then in order to radiating fin 30 to be set.Radiating fin 30 is made via operations such as shearing, bendings, and its section slightly is the U font, and forms joint portion 32 in the base, and dual-side forms radiating part 34.This joint portion 32 and the radiating part 34 common grooves 36 that form, the confession air carries out convection current and heat is taken away, and also is formed with groove 38 30 of adjacent two radiating fins, and its effect is identical with groove 36.Further offer otch 40 on the radiating fin 30,, form the heat dissipation channel that flows for air, be beneficial to cross-ventilation and dispel the heat, make radiator have better heat radiating effect to form perforations that intersect vertically of a groove 42 and groove 36,38.When this radiating fin 30 is set in parallel on pedestal 10 end faces 14, utilize frock that punching press is carried out in the joint portion 32 of radiating fin 30, joint portion 32 and pedestal 10 are combined as a whole, so can allow radiating fin 30 strong fixs on pedestal 10.Because through punching press, occur depressed part 44 and protuberance (figure does not show) on the bottom surface 12 of the upper surface of joint portion 32 and pedestal 10 respectively, wherein this protuberance can be processed and be removed, and to keep the flatness of bottom surface 12, pedestal 10 can be fitted tightly with thermal source.
See also shown in Figure 3ly, be the second embodiment of the present invention.This radiator comprises a pedestal and several radiating fins 50, wherein radiating fin 50 is that its section slightly is the L font by a metal plate brake forming, has joint portion 52 and radiating part 54, this radiating fin 50 is to be set in parallel on the pedestal, also is to be combined as a whole with impact style between the two.
See also Fig. 4 and shown in Figure 5, be the third embodiment of the present invention.This radiator comprises a pedestal and several radiating fins 60, and wherein radiating fin 60 is by a metal plate shear-bow moulding, has joint portion 62 and radiating part 64.Joint portion 62 is staggered in the both sides of radiating part 64, and when radiating fin 60 was set in parallel on the pedestal, two adjacent radiating fins, 60 staggered joint portions 62 will be owing to complementary relationship closely cooperates.Similarly, the pedestal of this embodiment is to combine with impact style with 60 of radiating fins.
See also shown in Figure 6ly, be the fourth embodiment of the present invention.This radiator comprises a pedestal and several radiating fins 70, and wherein radiating fin 70 is to be wavy by a bending and forming metallic sheets, has joint portion 72, radiating part 74 and top 76.72 of the joint portions of pedestal and radiating fin 70 are to be combined into one with impact style.
See also shown in Figure 7ly, be the fifth embodiment of the present invention.This radiator comprises a pedestal and several radiating fins 80, and wherein radiating fin 80 is by a bending and forming metallic sheets, have joint portion 82 and radiating part 84, and adjacent two radiating parts 84 fits tightly together.This pedestal also is to combine with impact style with 80 of radiating fins.
See also shown in Figure 8ly, be the schematic flow sheet of the manufacture method of radiator of the present invention, this method is divided into following step: (1) provides a pedestal 90 and several radiating fins 110, and this radiating fin 110 has joint portion 112 and radiating part 114; (2) be combined as a whole with pedestal 90 by the joint portion 112 of impact style, radiating fin 110 is fixed on the pedestal 90 radiating fin 110; (3) remove the protuberance 94 that forms because of punching press on pedestal 90 bottom surfaces 92, make pedestal 90 bottom surfaces 92 smooth.Not only structure is firm for the radiator made by above step, and radiating effect is good.
