Abstract
The invention discloses a fastening structure for radiation fins of a laptop, which comprises a radiation component formed by fastening a plurality of monolithic radiation fins together, wherein the radiation fins have upward-bent parts and downward-bent parts in the same direction; the upward-bent parts and the downward-bent parts form protruding 'trapeziform' connecting parts; 'trapeziform' connecting holes are formed on the upward-bent parts and the downward-bent parts respectively; the 'trapeziform' connecting holes extend to the bodies of the radiation fins; the protruding 'trapeziform' connecting parts and the 'trapeziform' connecting holes are in the same direction; and when the radiation fins are connected, the 'trapeziform' connecting part of a radiation fin is arranged in the 'trapeziform' connecting hole of a previous radiation fin, the end of the 'trapeziform' connecting part of the radiation fin sinks towards the inside of the body of the radiation fin, and the sunken end face is stopped by the side of the body of the previous radiation fin. The fastening structure has high firmness, low cost and good radiation performance.
Description
Technical field
The present invention relates to a kind of radiating fin, especially a kind of buckling structure of radiating fin for portable computer.
Background technology
The radiating fin that present laptop computer is used has a variety of structures, the employing that is connected with of each heat radiator is established a connecting link in addition heat radiator is together in series, what have establishes a hook and a connecting hole in addition at the heat radiator side, places connecting hole to finish the connection of multi-disc heat radiator by hook.Right these structures make that the radiating fin strength of joint is low, production cost is high and thermal diffusivity is not good.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of fastening structure of radiating fin for portable computer, this fastening structure makes that the radiating fin cost is low, connecting fastness, to reach radiating effect by force better.
The present invention for the technical scheme that solves its technical matters and adopt is: a kind of buckling structure of radiating fin for portable computer, comprise by most one chip radiating fins and fasten the radiating subassembly of forming mutually, radiating fin have one in the same way last kink and following kink, last kink and following kink form " ladder " type connecting portion that is protrusion respectively, form the connecting hole that is " ladder " type on last kink and the following kink respectively, and " ladder " type connecting hole extends to the radiating fin body, " ladder " type connecting portion is identical with " ladder " type connecting hole direction, when each radiating fin links to each other, " ladder " type connecting hole of a slice radiating fin before " ladder " type connecting portion of back a slice radiating fin can place just, in preceding a slice radiating fin body side, two waist correspondences of back a slice radiating fin " ladder " type connecting portion contact at two waists of preceding a slice radiating fin " ladder " type connecting hole to radiating fin body sunken inside and depression end face backstop in " ladder " type connecting portion termination of back a slice radiating fin.
Further technical scheme of the present invention is:
The upper and lower kink shape of radiating fin identical (being that the width height is identical), and the connecting portion on every radiating fin identical with the connecting hole position (it is identical promptly to fasten point).
The upper and lower kink and the radiating fin body of radiating fin are rectangular.
Last kink and following kink form two connecting portions that are " ladder " type respectively at interval, and forming two is " ladder " type connecting hole at interval respectively on last kink and the following kink.
The described depression cross section parallel with the radiating fin body is V-shape, and the end of V-shape is pointed in the radiating fin body.
The invention has the beneficial effects as follows: when each radiating fin links to each other, " ladder " type connecting hole of a slice radiating fin before " ladder " type connecting portion of back a slice radiating fin just can fasten and place, " ladder " type connecting portion termination depression forming V-shape of back a slice radiating fin and backstop are in preceding a slice radiating fin body side, and two waist correspondences of " ladder " type connecting portion of back a slice radiating fin contact at two waists of preceding a slice radiating fin " ladder " type connecting hole.The connecting portion of back a slice radiating fin is that the structure fastness is good in the connecting hole of a slice radiating fin before being equipped in like this, and cost is low, can guarantee again heat radiator vertically and the ventilation distance between every heat radiator equate, collateral security thermal diffusivity preferably, and appearance looks elegant.

Fig. 2 is that most sheet radiating fin of the present invention fastens the back structural representation;
Fig. 3 is the front view (FV) after most sheet radiating fin of the present invention fastens;
Fig. 4 is Fig. 3 left view.
Embodiment
Embodiment: a kind of buckling structure of radiating fin for portable computer, comprise by most one chip radiating fins and fasten the radiating subassembly of forming mutually, radiating fin have one in the same way last kink and following kink, last kink and following kink form " ladder " type connecting portion 1 that is protrusion respectively, form the connecting hole 2 that is " ladder " type on last kink and the following kink respectively, and " ladder " type connecting hole extends to the radiating fin body, " ladder " type connecting portion is identical with " ladder " type connecting hole direction, when each radiating fin links to each other, " ladder " type connecting hole of a slice radiating fin before " ladder " type connecting portion of back a slice radiating fin can place just, " ladder " type connecting portion termination 3 of back a slice radiating fin to radiating fin body sunken inside and the 31 end face backstops that cave in preceding a slice radiating fin body 41 sides, two waists 5 of a slice radiating fin " ladder " type connecting hole before two waists, 4 correspondences of back a slice radiating fin " ladder " type connecting portion contact at.
The upper and lower kink shape of radiating fin identical (being that the width height is identical), and the connecting portion on every radiating fin identical with the connecting hole position (it is identical promptly to fasten point).
The upper and lower kink and the radiating fin body of radiating fin are rectangular.
Last kink and following kink form two connecting portions that are " ladder " type respectively at interval, and forming two is " ladder " type connecting hole at interval respectively on last kink and the following kink.
The described depression cross section parallel with the radiating fin body is V-shape, and the end of V-shape is pointed in the radiating fin body.
Manufacture process of the present invention is: the connecting portion of the upper and lower kink of back a slice radiating fin fastens and places the connecting hole of the corresponding preceding upper and lower kink of a slice radiating fin to get final product, by that analogy, finish the connection of multi-disc radiating fin, thereby constitute the radiating fin subassembly.
