Abstract
The present invention relates to a composite radiator and a production method, wherein the composite radiator comprises a base and two radiating fin sets arranged on the base. The base is formed by a squeezing way; a first lug boss positioned at the center is extended upwards from the top surface, and two secondary lug bosses are respectively positioned at two side edges. The radiating fin sets are punched and bent into a wave shape by a metal sheet to form a plurality of uniplanar bottom sheets, side sheets upwards extending from both sides of each bottom sheet, and top sheets positioned between two adjacent side sheets and oppositely staggered with the bottom sheets.
Description
The present invention especially refers to a kind of radiating effect is good and overall structure is firm combined radiator and manufacture method thereof about a kind of combined radiator and manufacture method thereof.
More and more wide along with the fast development of information industry and range of application thereof, also more and more high to the requirement of computer internal electronic element processing speed.Be accompanied by the raising of the speed of service, the heat that associated electronic components produces also rolls up, and if untimely with this heat discharge, the stability of use and quality will be greatly affected.
The existing radiator that is used for assisting electronic component to discharge heat is constructed, can be with reference to United States Patent (USP) the 5th, 304, and No. 846.As shown in Figure 1, this radiator 1 comprises a pedestal 3 and some it is fitted on the associated electronic components with pedestal 3 bottom surfaces from pedestal 3 upwardly extending radiating fins 5, and the heat that electronic component produces is in time discharged.Owing to adopting tradition (Extruding) mode that extrudes, radiator 1 gets, therefore under the restriction of manufacturing technology level, mould strength etc., on the design of the radiating effects that concern such as radiating fin density or integral heat sink surface area is considered, be difficult to realistic user demand.
Moreover, combined radiator is as shown in Figure 2 also arranged, this radiator 10 is made up of a pedestal 11 and some radiating fins 15 that is plugged on the pedestal 11.Make because the radiating fin 15 of this type of radiator 10 changes with impact style, therefore on radiating fin density and integral heat sink surface area, have bigger design space.But because the radiating fin 15 of this type of radiator 10 with the direct inlay card of plant mode in the groove 13 of pedestal 11, so integrally-built steadiness is obviously not enough, and the joint at radiating fin 15 and pedestal 11 grooves 13 also is easy to generate the space, and influences the radiating effect of radiator 10 greatly.
In addition, Figure 3 shows that another type radiator, this radiator 20 is made of a pedestal 21 and some radiating fin groups 23 that is bonded on the pedestal 21.Because this type of radiator 20 only clings this radiating fin group 23 and pedestal 21 with heat-conducting glue, therefore obviously not enough on integrally-built steadiness, and since this heat-conducting glue be in for a long time under the hot environment, therefore very easily aging and cause viscosity to descend or lose viscosity.
Therefore, how to provide the radiator that a kind of radiating effect is good and overall structure is firm, become the task of top priority.
The objective of the invention is to: a kind of radiating effect is good and overall structure is firm combined radiator and manufacture method thereof are provided.
Combined radiator of the present invention and manufacture method thereof are reached above-mentioned purpose by following means, and this combined radiator comprises a pedestal and two radiating fin groups that are installed on the pedestal.This pedestal is formed by the mode of extruding, and its end face extends upward one and is positioned at the first central boss, and two second boss that lay respectively at both side edges.This radiating fin group is bent into wavy through punching press by sheet metal, with form several coplanar egative films, from the upwardly extending lateral plate in egative film both sides, and be positioned between adjacent two lateral plates and relative staggered top flat with egative film.
Compare prior art, the resulting radiator of the present invention has the advantage that radiating effect is good and overall structure is firm.

The present invention is further illustrated below in conjunction with embodiment and with reference to accompanying drawing:
Please together consulting Fig. 4 and Fig. 5, is first embodiment of combined radiator of the present invention and manufacture method thereof, and this combined radiator 30 comprises a pedestal 31 and two radiating fin groups 41 that are installed on the pedestal 31.
This its seat 31 is formed by the mode of extruding, and its end face 33 extends upward first boss 34 that is positioned at central authorities, and two second boss 35 that lay respectively at both side edges.This first boss 34 forms one first groove 38 respectively and slightly is " T " font in both sides, this second boss 35 then forms one second groove 39 in the inboard.
This radiating fin group 41 is bent into wavy through punching press by sheet metal, with form several coplanar egative films 42, from the upwardly extending lateral plate 43 in egative film 42 both sides, and be positioned at 43 of adjacent two lateral plates and with egative film 42 relative staggered top flats 45.This egative film 42 further extends a protuberance 46 outwardly respectively at two ends, this protuberance 46 protrudes in outside lateral plate 43 lateral margins, with match with first groove 38 of pedestal 31 and second groove, 39 structures (back detailed description).
During assembling, the size by 39 of protuberance 46 and pedestal 31 first grooves 38 and second grooves cooperates, and two radiating fin groups 41 are slipped on the end face 33 that is installed in pedestal 31.Afterwards, utilize suitable tool to impact on first boss 34 of pedestal 31 and second boss 35 position again corresponding to radiating fin group 41 protuberances 46, promptly form inside pressing part 37 towards lower recess on this first boss 34 and second boss 35 this moment, with the protuberance 46 that firmly compresses radiating fin group 41, and radiating fin group 41 firmly is installed on the pedestal 31.
Moreover 33 of the egative film 42 of this radiating fin group 41 and the end faces of pedestal 31 can add suitable heat-conducting medium, as heat-conducting cream (thermal grease) or heat conduction adhesive tape (thermal tape) etc., with further raising radiating effect.
Please consult Fig. 6 and Fig. 7 again, be second embodiment of combined radiator of the present invention and manufacture method thereof, its overall structure and manufacture method are similar to aforementioned first embodiment.First boss, 34 ＇ and second boss, 35 ＇ of these combined radiator 30 ＇ pedestals 31 ＇ are simple raised line shapes, be not formed with groove structure, and correspondingly, the two ends of these radiating fin group 41 ＇ egative films 42 ＇ flush with the lateral margin of lateral plate 43 ＇, do not protrude in outside the lateral plate 43 ＇ lateral margins.During assembling, utilize tool to impact first boss, 34 ＇ and the last position of second boss, 35 ＇ of pedestal 31 ＇ corresponding to radiating fin group 41 ＇ egative films 42 ＇ two ends, promptly form inside pressing part 37 ＇ on this first boss 34 ＇ and second boss, 35 ＇ towards lower recess, firmly compressing egative film 42 ＇ of radiating fin group 41 ＇, and radiating fin group 41 ＇ firmly are installed on pedestal 31 ＇.
