Abstract
The utility model discloses a fastening structure of fins used in a notebook computer, and comprises a heat dissipation component comprising a plurality of single-plate type fins that are fastened with each other. The fin is provided with an upper kink part and a lower kink part that are in the same direction. The upper kink part and the lower kink part form respectively protuberant 'T'-shaped connection parts and 'T'-shaped connection holes; the 'T'-shaped connection holes extend to a body of the fin. The protuberant 'T'-shaped connection parts and the 'T'-shaped connection holes are in the same direction; when fins are connected with each other, the protuberant 'T'-shaped connection part of a back fin can be suitably positioned on the 'T'-shaped connection hole of a front fin; the end of the 'T'-shaped connection part of the back fin is sunken towards the fin body, the sunken end stops the lateral side of the front fin body, the shoulder of the 'T'-shaped connection part of the back fin is tightly contacted with the shoulder of the 'T'-shaped connection hole of the front fin. The fastening structure of the utility model has good fastness, low cost and good heat dissipation.
Description
Technical field
The utility model 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 utility model provides a kind of fastening structure of radiating fin for portable computer, and this fastening structure makes that the radiating fin cost is low, connecting fastness, to reach radiating effect by force better.
The utility model 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 the T-shape connecting portion that is protrusion respectively, form the connecting hole that is T-shape on last kink and the following kink respectively, and the T-shape connecting hole extends to the radiating fin body, the T-shape connecting portion is identical with T-shape connecting hole direction, when each radiating fin links to each other, the T type connecting hole of a slice radiating fin before the T type connecting portion of back a slice radiating fin can place just, in preceding a slice radiating fin body side, the shoulder of back a slice radiating fin T type connecting portion contacts at the shoulder of preceding a slice radiating fin T type connecting hole to radiating fin body sunken inside and depression end face backstop in the T type connecting portion termination of back a slice radiating fin.
Further technical scheme of the present utility model 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 T-shape respectively at interval, and forming two is the T-shape 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 beneficial effects of the utility model are: when each radiating fin links to each other, the T type connecting hole of a slice radiating fin before the T type connecting portion of back a slice radiating fin just can fasten and place, the T 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 the shoulder of the T type connecting portion of back a slice radiating fin contacts at the shoulder of preceding a slice radiating fin T 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.

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 the T-shape connecting portion 1 that is protrusion respectively, form the connecting hole 2 that is T-shape on last kink and the following kink respectively, and the T-shape connecting hole extends to the radiating fin body, the T-shape connecting portion is identical with T-shape connecting hole direction, when each radiating fin links to each other, the T type connecting hole of a slice radiating fin before the T type connecting portion of back a slice radiating fin can place just, the T 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, the shoulder 5 of a slice radiating fin T type connecting hole before the shoulder 4 of back a slice radiating fin T type connecting portion contacts 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 T-shape respectively at interval, and forming two is the T-shape 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 utility model 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.
