Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1: referring to accompanying drawing 1 to Fig. 6.The orientation title such as forward and backward, upper and lower in present specification is all take figure one as reference, and these orientation titles only are to understand the technical solution of the utility model, it are not construed as limiting.
a kind of structure improved radiator, as Fig. 1, shown in Figure 2, comprise a plurality of metal fixed blocks 2 that be arranged in parallel, the leading flank of described metal fixed block 2 is provided with at least one protruding joint pin 11, the trailing flank of described metal fixed block 2 is provided with the connecting hole corresponding with joint pin 11 15, at least be provided with a fin 3 between described two adjacent metal fixed blocks 2, described fin 3 is provided with the groove 21 that inserts for joint pin 11, the joint pin 11 that is positioned at the metal fixed block 2 of rear side in two adjacent metal fixed blocks 2 passes the groove 21 of corresponding fin 3 and the connecting hole 15 that insertion is positioned at the metal fixed block 2 of front side, and joint pin 11 and fin 3 riveted joints.
The technical program is when implementing, metal fixed block 2 and fin 3 are separately positioned on the both sides of workbench, metal fixed block 2 and fin 3 are by the processing stand operation of connecting gear to middle part, metal fixed block 2 moved to precalculated position before this, then fin 3 moves to the upside of metal fixed block 2, and what arrange due to fin 3 is groove 21, be joint pin 11 in conjunction with the time, can be nested into smoothly on joint pin 11, realize that fin 3 is attached to the surface of metal fixed block 2; Then second metal fixed block 2 moves to processing stand, the first metal fixed block 2 moves down certain distance, when second metal fixed block 2 moves to processing place, the connecting hole 15 of the trailing flank of the second metal fixed block 2 just in time with the joint pin 11 of first metal fixed block 2 with respect to, the second metal fixed block 2 is to pressing down joint pin 11, and the upper end of joint pin 11 is upsetting, and joint pin 11 is with connecting hole 15 interference fit or coordinate, simultaneously fin 3 is riveted on joint pin 11, so repeatedly.The radiator of this structure is riveted on fin 3 on corresponding joint pin 11 by metal fixed block 2 successively, stable connection, simultaneously adjacent metal fixed block 2 links together by joint pin 11 and the interference fit of connecting hole 15, make whole fin 3 need not connector, and connect compact.Certainly,, if machining accuracy is high,, as equivalent variations, can adopt through hole to substitute groove 21.
Joint pin 11 and connecting hole 15 when making, can directly generate by punching press, and processing is simple.
Further, as shown in Figure 6, described groove 21 is horn-like.
When fin 3 coordinates with metal fixed block 2, the groove of fin 3 21 need to be enclosed within outside joint pin 11.Loosening in order to prevent fin 3, when design, the width of General Requirements groove 21 is the same large with the diameter of joint pin 11, and this just requires the precision of processing, and makes fin 3 when mobile, and its groove 21 is just relative with joint pin 11.Otherwise can bending radiating fin 3.With groove 21 setting be horn-like after, the openend of groove 21 opens to both sides, forms larger opening, is convenient to joint pin 11 interspersed.Groove 21 imports can be enclosed within outside joint pin 11,, along with the movement of fin 3,, by coordinating of groove 21 and joint pin 11, make fin 3 progressively revise the position of oneself, reduce processing.
Further, as shown in Figure 3, in two adjacent metal fixed blocks 2, the metal fixed block 2 that is positioned at rear side is extended with forward at least one contiguous block 13, and the metal fixed block 2 that is positioned at front side is provided with the hole clipping 14 that matches with contiguous block 13.
For metal fixed block 2 is closely connected successively, the technical program has designed contiguous block 13 and hole clipping 14; Wherein contiguous block 13 can be that metal fixed block 2 extends outward, as shown in Figure 4, and then by being bent to form forward.In the course of processing, after metal fixed block 2 connects successively by joint pin 11, then by pressing plate, all contiguous blocks 13 are bent successively, snap onto after making the contiguous block 13 of the metal fixed block 2 of rear side bend in the hole clipping 14 of metal fixed block 2 of front side.
Further, as shown in Figure 3, described contiguous block 13 is trapezoidal, and the cross-sectional area of front end is greater than the cross-sectional area of rear end.
With contiguous block 13 design be trapezoidal after, it is trapezoidal that hole clipping 14 also is, contiguous block 13 is with after hole clipping 14 coordinates like this, two adjacent metal fixed blocks 2 can not outwards separate, thus stable fin 3 is clamped in therebetween.Simultaneously adjacent two metal fixed blocks 2 connect closely.
Further, described contiguous block 13 is T-shaped or L shaped.
In design, the position of contiguous block 13 can be selected according to actual conditions, as the upper end at metal fixed block 2, left end, right-hand member etc., all can arrange, and a place can be set, and also many places can be set.The present embodiment, as simple explanation, is arranged on contiguous block the upper end of metal fixed block 2.
Further, as shown in Figure 5, described radiator also comprises heat pipe 1, and the lower end of described metal fixed block 2 is provided with for the installing hole 12 that heat pipe 1 is installed, and an end of heat pipe 1 inserts described installing hole 12.
Further, as shown in Figure 3, the lower end of described fin 3 also is provided with for the installing hole 12 that heat pipe 1 is installed.
At fin 3, installing hole 12 is set, makes heat pipe 1 after installation, can contact with fin 3 and metal fixed block 2, enlarge active surface, improve radiating efficiency.
Further, described fin 3 is provided with louvre 22.
Embodiment 2: a kind of structure improved radiator, its structure difference from Example 1 is the design of contiguous block 13 and connecting hole 15, as Fig. 7, Fig. 8, shown in Figure 9, described contiguous block 13 is provided with connection chamber 17, and the middle part of described hole clipping 14 is provided with the projection 16 with connection chamber 17 clampings.
In design process, two metal fixed blocks 2 that front and back are adjacent for convenience couple together, here adopted the flanging technology, when producing, contiguous block 13 is in a plane with metal fixed head 2, after metal fixed head 2 and fin 3 are completed riveted joint, again with contiguous block 13 bendings, make the contiguous block 13 on the metal fixed block 2 that is positioned at rear before bend, and this contiguous block 13 just snaps in hole clipping 14 in the metal fixed block 2 in the place ahead, simultaneously the connection chamber 17 of contiguous block 13 just is enclosed within on projection 16 in hole clipping 14, as shown in Figure 7, forms snapping.So just, two adjacent metal fixed blocks 2 are coupled together, a plurality of metal fixed blocks 2 are connected in series.Metal fixed block 2 can adopt the making such as thick aluminium sheet.Its material is unrestricted.
Secondly, in the design, contiguous block 13 designs are in the both sides up and down of metal fixed block 2, and its every side is provided with two.Certainly in actual production process, contiguous block 13 can come design attitude and number as required, as the centre position that is arranged on the both sides, up and down respectively arranges one, so the design of the position of contiguous block 13 and number is unrestricted in this application.
In addition, the shape of the joint pin 11 on metal fixed block 2 can be: the cross section of joint pin 11 triangular in shape or hexagon or circle or rhombus or semicircle.And this cross section is perpendicular to the length direction of contiguous block.As shown in Figure 8,9.The shape of joint pin 11 can be according to actual production, need to design, its shape unrestricted in this application.
Be only below the application's preferred embodiment, equivalent technical solutions on this basis still falls into the application protection range, as changing position, the number of contiguous block 13; And the schemes such as shape of joint pin 11.
