The required extruding pressure is small, an extruded product can form strong convection, and the heat dissipating efficiency can be improved.
Description
Technical field
The present invention relates to a kind of flow guiding aluminium alloy radiator section bar, particularly relate to a kind of buckle-type flow-guiding type aluminium alloy heat sink section bar.
Background technology
China is industrial power, along with the manufacturing industry of progressive China of science and technology is flourish, economy is become stronger day by day, and new technologies and materials is constantly emerged in large numbers, wherein aluminium alloy one of them, as almag, it has excellent mechanical performance and chemical property, is widely used in various field, as in radiator field, normal in electronics, electrical industry application is main material with aluminium alloy extrusions, as the thermal component of parts or machine.The existing aluminium section bar as radiator is all be made up of substrate and wing plate, during use, substrate contacts with heat generating components and connects, then by wing plate heat radiation, existing wing plate is all open being arranged side by side, wing plate distributes heat in air by directly contacting with air, so air flow property is most important to its emission efficiency, when not having wind, this structure cannot form larger convection current, so radiating efficiency is lower.Mostly this aluminium alloy extrusions is to be produced by expressing technique, during production extrusion molding hollow tubular product, aluminium alloy base first will enter multiple runner and arrive extrusion, converge again and combine together by extrusion extrusion molding, aluminium alloy base enters in multiple runner process and is separated into that multichannel is invisible improves resistance, need higher squeeze pressure ability shaping, affect by stable process conditions when multichannel aluminium alloy base converges and also easily occur fold or crack, these still await technology and solve.
Summary of the invention
In order to solve the problem, the invention provides a kind of buckle-type flow-guiding type aluminium alloy heat sink section bar.
The technical solution used in the present invention is: a kind of buckle-type flow-guiding type aluminium alloy heat sink section bar, it is characterized in that comprising main substrate and wing plate, main substrate and wing plate are elongated plates, the one side of main substrate is heat radiation joint face, wing plate is connected to the another side of the main substrate contrary with radiating surface, wing plate and longitudinal direction vertical with this joint face and main substrate longitudinal direction consistent, wing plate is at least more than three odd numbers, spacing transverse slat is connected with away from main substrate side from side number even number wing plate, be connected with wing plate in the middle part of spacing transverse slat, spacing transverse slat is close to main substrate gradually to both sides free end by wing plate end, be connected with the elastic plate extended to contiguous spacing transverse slat direction away from main substrate side from side number odd number wing plate, elastic plate free end to main substrate gradually away from, spacing transverse slat free end is positioned at the below of contiguous elastic plate free end and possesses gap, dispelling the heat with main substrate, joint face vertical direction upper limit transverse slat free end is overlapping with the projection of contiguous elastic plate free end to be overlapped, elastic plate free end can stick into below contiguous spacing transverse slat free end.
Further, described adjacent vanes spacing is at 10 millimeters to 20 millimeters.
Further, described elastic plate and/or spacing transverse slat are provided with thinning area extending longitudinally.
Be non-occluded configuration when aluminium alloy extrusions of the present invention is extruded, need not arrange runner to extrusion die outlet, need squeeze pressure less, need energy ezpenditure less, aluminium material surface fold and crack occurrence probability little, only need apply pressure during use and engage.During use, main substrate absorbs the heat of components and parts and transfers heat to wing plate, elastic plate and spacing transverse slat, heating part transfers heat to ambient air simultaneously, main substrate, wing plate, elastic plate and spacing transverse slat surround some longitudinal gas channels, air heats in air flue rises and is flowed out by upper shed, normal temperature air enters supplementary by air flue under shed, can form a stronger convection current, improves radiating efficiency.
