Description
Technical field
The present invention relates to the fin that a kind of aluminium alloy extruded section steel cutting makes, particularly relate to the clipping aluminum alloy heat sink of a kind of elastic clip.
Background technology
China is industrial power, and along with the manufacturing industry of progressive China of science and technology is flourish, economy is become stronger day by day, 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, be 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, there is good heat dispersion, there is moderate price advantage simultaneously.Existing is all be made up of substrate and wing plate as the aluminium section bar of power tube radiator in electronic product, during use, substrate contacts with heat generating components and connects, then by wing plate heat radiation, when substrate is connected with power tube, usually be all power tube is first fixed on radiator by screw substrate on be welded to circuit board again, the fastening dynamics of screw is not fine assurance, sensation entirely with workman operates, cross pine and affect heat trnasfer, tension easily produces the performance of stress influence power tube to encapsulation, expand with heat and contract with cold produce the bad performance that also can affect power tube of Stress Release, and power tube also can be made displacement is produced when turn-knob screw, make it out of position, affect later stage installation or irregular after installing, be welded on circuit board and be easy to damage pad by the turn-knob power that screw installation of heat radiator produces again, above problem can only lean on the qualification of workman to solve at present, and each radiator wants thread mill drilling or boring, fabrication and installation process is all cumbersome, these still await technology and solve.
Summary of the invention
In order to solve the problem, the invention provides the clipping aluminum alloy heat sink of a kind of elastic clip.
The technical solution used in the present invention is: the clipping aluminum alloy heat sink of a kind of elastic clip, it is characterized in that comprising aluminum alloy body and elastic clip, aluminum alloy body is provided with backboard, transverse slat, wing plate and clamping plate, transverse slat is connected to edge on backboard and both are mutually vertical overall in inverted "L" shaped, wing plate to be connected to above transverse slat and equidistantly to be arranged to away from backboard side by backboard side, clamping plate are positioned at below transverse slat and its upper end and are connected away from backboard side with transverse slat by wavy shell fragment, clamping plate hypomere is arc, the arc core axis of arc respectively with transverse slat below, parallel with the backboard inner face be connected below transverse slat, the back side contrary with arc core on arc is an arc pressure surface, arc pressure surface is near backboard, arc arc core side and the backboard back side are respectively equipped with the stopper slot with the arc centre axis parallel of arc, elastic clip is U-shaped folder, two bare terminal ends of U-shaped folder coincide respectively in two stopper slots.
Further, described stopper slot is the groove of recessed backboard and arc respectively.
Further, described stopper slot is surrounded by the muscle of outstanding backboard and arc respectively.
Power tube is placed between pressing plate and backboard when using by aluminum alloy heat sink of the present invention, then two bare terminal ends of U-shaped folder are coincide respectively in two stopper slots, because wavy shell fragment has certain deformability, arc pressure surface on U-shaped folder elastic force effect lower platen is pressed on power tube, make power tube near on backboard, the constant reliable stress of blessing power is little, the stress expanding with heat and contract with cold and produce can be discharged fully, improve power tube encapsulation performance, install easily, position can not produce torsion shift phenomenon when screw is fixed, also can first two bare terminal ends of U-shaped folder be coincide respectively in two stopper slots, then pressing plate is strutted with instrument and power tube put into by backboard, be suitable for power tube to be first welded on circuit board at installation fin, reduce the weight of circuit board during wave soldering, the absorption reducing heat energy during welding ensures welding stability, this fin is suitable for expressing technique and makes, section bar can be applied after cutting off, without the need to thread mill drilling, fabrication and installation process is all fairly simple, be suitable for applying.
