Abstract
The utility model relates to a heat radiation fin with an improved structure, which comprises a fixing base, the upper edge of the fixing base is provided with a plurality of longitudinal embedding grooves, and the vertical embedding number is matched with the longitudinal embedding grooves. A plurality of heat radiating fin bodies are vertical to the fixing base, the width and the length of the heat radiating fin body are equal to the fixing base, the utility model also comprises a cover shell which is combined on the fixing base and can cover a plurality of heat radiating fin bodies, and a central circular hole is provided with screw holes for placing a heat radiation fan. The utility model ha the advantages of good radiation effect, simple structure and low cost.
Description
The utility model relates to a kind of fin that improves structure, refers to a kind of integral heat sink sheet by holder, multi-disc fin lamellar body and case institute be combined into especially.
Aluminium is high-thermal conductive metal, and is highly desirable as the material of fin.Because its material is softer, is suitable for monolithic extruded moulding, still, its fin need but be difficult to accomplish with the higher lamellar body extrusion molding simultaneously of multi-disc.Now the fin that uses all be short and small heat radiation lamellar body perpendicular on the substrate, its radiating effect is restricted, and then influences the normal operation of computer.In addition, also have and adopt casting forming, not only production cost is higher, and fin lamellar body or needle body have the bubble to exist easily, so that brisement is in mould during the demoulding, difficult treatment increases production cost virtually again.
Main purpose of the present utility model is to solve aforesaid difficulty and a kind of fin that improves structure is provided, this fin is that employing is aluminum extruded, the holder that most caulking grooves are arranged, and the chimeric multi-disc heat radiation lamellar body that has a plurality of aluminium flat sheets to make suitable height, constitute in conjunction with case outside again, can realize the requirement of high heat radiation.
The utility model is achieved in that it comprises: a holder is the rectangle lamellar body that is formed by the fine aluminium extrusion, and there is the formed groove in order to chimeric case of the flange of suitable height both sides; There are most bar caulking grooves of vertical cooperation fin body thickness in central authorities, in order to respectively chimeric heat radiation lamellar body one side location; One heat radiation lamellar body, its quantity cooperates the caulking groove of aforementioned fixation seat, has the width of setting, and a side is located perpendicular to aforementioned fixation seat caulking groove respectively; And a case, for slightly being down " U " shape cover, two ends are opening respectively, and upper limb central authorities have in order to the circular hole in conjunction with cooling fan.
Wherein the heat radiation lamellar body caulking groove of holder upper limb is made of paired arc lug.
The utility model is a kind of fin that improves structure, includes: a upper limb has many vertical caulking grooves, the holder of the fin that vertically fitting quantity cooperates; Multi-disc is set width, length is identical with holder and perpendicular to the heat radiation lamellar body of holder, and one be combined in cover on the holder and close the dispel the heat case institute be combined into of lamellar body of multi-disc, and hole, central garden is provided with device radiation fan screw.Good heat dissipation effect of the present utility model, and simple in structure, production cost is lower.
Structure of the present utility model and function are described in detail as follows with reference to embodiment and accompanying drawing:
Fig. 1 is stereoscopic figure of the present utility model.
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of Fig. 1.
Fig. 3 is structure of fixed holder and the partial enlarged drawing thereof of another embodiment of the utility model.
See also Fig. 1, shown in Figure 2, the fin (1) of the utility model first embodiment is by holder (2), heat radiation lamellar body (3) and case (4) institute be combined into.Wherein holder (2) is the rectangle lamellar body that is formed by the fine aluminium extrusion, and both sides are provided with the formed groove of flange (5) of suitable height, in order to chimeric fixedly case (4).Middle position has many caulking grooves (6) of vertical cooperation heat radiation lamellar body (3) thickness, in order to a side of the heat radiation lamellar body (3) of chimeric proper width respectively, it is located perpendicular to holder (2).There is combined hole (7) this holder (2) both sides, in order in conjunction with case (4).Aforementioned heat radiation lamellar body (3) is to be formed by fine aluminium plain film crush-cutting, and length cooperates holder (2), and width cooperates the heat dissipation capacity requirement, is embedded in holder (2) location with a side respectively.Case (4) is for slightly being down " U " shape cover, and is also made by fine aluminium, and two ends are opening respectively, the all sides of upper limb central circular hole (8) have some screws (9), in order to installing cooling fan (not showing on the figure),, reach the effect of quickening heat radiation to promote the flow velocity of air between heat radiation lamellar body (3).
Consult holder (2) structure of second embodiment of the present utility model shown in Figure 3, it also is to be formed by the fine aluminium extrusion, be the rectangle lamellar body, upper limb has most caulking grooves (6) that arc lug (10) is constituted, in order to chimeric heat radiation lamellar body (3), this heat radiation lamellar body (3) is identical with the structure and first embodiment of case (4), so do not repeat them here.
Claims (2)
1, a kind of fin that improves structure, it is characterized in that: it comprises: a holder is the rectangle lamellar body that is formed by the fine aluminium extrusion, and there is the formed groove in order to chimeric case of the flange of suitable height both sides; There are most bar caulking grooves of vertical cooperation fin body thickness in central authorities, in order to respectively chimeric heat radiation lamellar body one side location; One heat radiation lamellar body, its quantity cooperates the caulking groove of aforementioned fixation seat, has the setting width, and a side is located perpendicular to aforementioned fixation seat caulking groove respectively; And a case, for slightly being down " U " shape cover, two ends are opening respectively, and upper limb central authorities have in order to the circular hole in conjunction with cooling fan.
2, the fin of improvement structure as claimed in claim 1 is characterized in that: the heat radiation lamellar body caulking groove of holder upper limb wherein is made of paired arc lug.
