[embodiment]
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
As shown in Figures 3 and 4, radiator of the present invention comprises some radiating fins that combine 10, each radiating fin 10 comprises a body 12 and two flangings 14, this two flanging 14 bends perpendicular to this body 12 in the same way from this limit, body 12 two opposite sides respectively, each flanging 14 is provided with a slot 17 with this inboard, body 12 junction, and this slot 17 is arranged at the centre position of corresponding flanging 14.The card 16 that these flanging 14 external end edges plug together mutually to should slot 17 positions stretch out a width and slot 17, the leading edge of card 16 forms a camber line limit.The position that is connected of this card 16 and flanging 14 form one to radiating fin 10 in the butting section 160 of lateral buckling, owing to the existence of this butting section 160, make this card 16 and corresponding flanging 14 with these flanging 14 vertical direction on differ the thickness of a flanging 14.In addition, but body 12 centre positions of each radiating fin 10 also are provided with the through hole 19 that heating tube wears.
The card 16 of each radiating fin 10 of assembling back is arranged in the slot 17 of adjacent last radiating fin 10 and is resisted against flanging 14 inboards, butting section 160 1 sides of card 16 are resisted against on the body 12 of last radiating fin 10, and opposite side is resisted against flanging 14 contiguous slots 17 positions of last radiating fin 10.
Fig. 5 is the manufacturing flow chart of radiator of the present invention, comprises following three steps: at first provide some radiating fins; Then described radiating fin is spliced mutually, at last the flanging of described radiating fin is carried out punching press and form radiator of the present invention.Introduce the manufacture process of radiator of the present invention in detail below in conjunction with Fig. 6 to Fig. 8.
With reference to Fig. 6, some radiating fins 10 ' at first are provided, each radiating fin 10 ' comprises a body 12 and two flangings 14 ' that bend in the same way perpendicular to this body 12 from this limit, body 12 two opposite sides, each flanging 14 ' is provided with a slot 17 with the roughly centre position of these body 12 junctions, flanging 14 ' the inboard depression 20 that is communicated with this slot 17 that forms, corresponding to this depression 20, this flanging 14 ' forms a convex closure 18 in its outside.The corresponding slot 17 of this flanging 14 ' leading edge is provided with a card 16 ', and this card 16 ' roughly is square, and outer rim forms the camber line limit, and card 16 ' and flanging 14 ' are in same plane.
Simultaneously with reference to Fig. 7 and Fig. 8, then with the splicing mutually of above-mentioned radiating fin 10 ', the card 16 ' of each radiating fin 10 ' passes the slot 17 of adjacent last radiating fin 10 ' and is positioned at the depression 20 of last radiating fin 10 ', and the flanging 14 ' of back one radiating fin 10 ' connects with the lateral margin of the body 12 of last radiating fin 10 '.
At last, flanging 14 ' to above-mentioned radiating fin 10 ' flattens, the convex closure 18 of each radiating fin 10 ' is deformed into and flanging 14 ' coplane, the card 16 ' that is positioned at depression 20 places is then to internal strain, the binding site of card 16 ' and flanging 14 ' is owing to be subjected to the butting section 160 that formation herein bends inwards that is blocked in of body 12, the final radiator that forms as shown in Figure 3, wherein 160 both sides, butting section are resisted against respectively on the body 12 and flanging 14 of adjacent last radiating fin 10, thereby limit radiating fin 10 perpendicular to moving on the direction of the body 12 of radiating fin 10, card 16 ' one side contacts with flanging 14, thus limit radiating fin 10 with body 12 parallel directions of radiating fin 10 on move.
